Zinc Lozenges vs Zinc Supplements for Immune Support

Zinc lozenges vs zinc supplements is not a question of which one is better overall, because they are built for different jobs. Zinc lozenges dissolve in the mouth and release zinc ions directly in the throat, where they may help shorten a common cold when started within 24 hours of the first symptoms. Zinc supplements, sold as tablets and capsules, are swallowed and absorbed through digestion to correct zinc deficiency and support long-term immune function. In short, reach for lozenges at the first sign of a cold and use a daily supplement for steady, everyday immune defense. This guide compares how each one works, what the research shows, the right dosage for each type, side effects, and how to choose.

Zinc Lozenges vs Zinc Supplements at a Glance

The table below summarizes the main differences between the two forms before the sections that follow explain each point in detail.

How Zinc Lozenges Work vs How Zinc Supplements Work

The distinction between lozenges and supplements is not a marketing difference. It is a mechanistic one that determines whether you get the specific benefit you are after.

Zinc lozenges work locally. When a lozenge dissolves slowly in the mouth, it releases free ionic zinc into the oral cavity and throat. This localized zinc concentration is what is thought to drive the antiviral effect seen in cold trials. Researchers believe ionic zinc interferes with the ICAM-1 receptor binding that rhinoviruses use to attach to nasal and throat cells, and that it may also disrupt viral replication before the infection can establish itself. This process happens at the mucosal surface, which means the zinc must be present there in ionic form to work.

Zinc supplements bypass this mechanism entirely. They are digested and absorbed in the small intestine, then distributed systemically. This systemic availability is exactly what you need for correcting zinc deficiency, supporting immune cell production, enabling wound healing, and maintaining the enzymatic functions that zinc governs across the body. It is just not what you need to target a cold virus in your throat in the first forty-eight hours of illness.

What Are Zinc Lozenges Good For?

The main proven use of zinc lozenges is shortening the duration of the common cold in adults. Because colds caused by rhinoviruses often begin with a scratchy throat, lozenges are well suited to that early window, and people commonly use them alongside rest and fluids when symptoms like sore throat, nasal congestion, and cough first appear. Research has focused on overall cold duration rather than sore throat relief specifically, so the strongest reason to use them is to cut the illness short rather than to soothe one symptom. Zinc lozenges are not a substitute for a daily zinc supplement, and they are not proven for the flu or other infections, as covered later in this guide.

Zinc Lozenges Benefits for Sore Throat and Cold Symptom Relief

Many people search for zinc lozenges because a sore throat is often the first sign of a cold. It helps to separate what zinc lozenges are proven to do from what they are commonly used for. The benefit shown in clinical trials is a shorter cold overall, measured across symptoms such as sore throat, nasal congestion, sneezing, and cough, rather than fast relief of any single symptom.

Do Zinc Lozenges Help a Sore Throat?

Zinc lozenges can be part of your approach to a sore throat caused by a cold, because they act in the throat during the early phase of the infection. They are not designed as a numbing throat lozenge, and some people find the taste and mild mouth irritation make a sore throat feel worse at first. If your main goal is comfort, warm fluids, rest, and a spoonful of honey (for anyone over one year old) can sit alongside zinc. A sore throat that is severe, lasts more than a week, or comes with a high fever is a reason to see a doctor rather than rely on lozenges.

Zinc Lozenges for Cough and Congestion

Cough and nasal congestion were among the symptoms tracked in the trials that showed a shorter cold with zinc lozenges, so these symptoms may clear sooner when lozenges are started early. Zinc lozenges are not a cough suppressant or decongestant, though, and they work best as one part of a cold plan that includes rest, fluids, and time. If you are getting back on your feet after a cold, our guide on how to rebuild your immune system after illness covers the recovery phase.

What the Research Actually Shows on Cold Duration

The clinical evidence for zinc lozenges is real but specific. A 2024 Cochrane review found that zinc may shorten cold duration by approximately two days, though it rated the certainty of evidence as low due to formulation variability across trials. A 2017 meta-analysis of seven placebo-controlled lozenge trials found that zinc lozenges shortened colds by 33 percent on average, with zinc acetate lozenges shortening colds by about 40 percent compared to placebo.

Formulation explains much of the inconsistency across studies. Lozenges using zinc acetate or zinc gluconate as the sole zinc compound are the ones that have shown meaningful benefit. Formulations containing additives like citric acid, tartaric acid, or sorbitol tend to show little or no effect. These additives bind ionic zinc before it can act in the throat, which is why many flavored lozenges underperform in trials.

Timing is the other critical variable. The trials showing meaningful cold-shortening benefit generally enrolled participants who started zinc within 24 hours of symptom onset. Waiting beyond this window appears to reduce or eliminate the benefit, because the mechanism targets early infection, not advanced illness.

Zinc Acetate vs Zinc Gluconate Lozenges

Zinc acetate and zinc gluconate are the two lozenge forms with the most research behind them. In the 2017 meta-analysis, zinc acetate trials showed a 40 percent reduction in cold duration and zinc gluconate trials a 28 percent reduction, but the difference between the two was not statistically significant. The study's author concluded that properly formulated zinc gluconate lozenges may be as effective as zinc acetate lozenges. The trials used 80 to 92 mg of elemental zinc per day in most cases, and the review found no evidence that doses above 100 mg per day work better. In practice, the absence of zinc-binding additives matters more than which of the two salts you choose.

How Quickly Do Zinc Lozenges Work?

Zinc lozenges don't work like a pain reliever you feel within minutes. Their effect shows up as a cold that ends sooner, so most people notice the difference over several days rather than after the first lozenge. This is also the main practical difference between zinc lozenges and zinc pills when it comes to speed.

What to Expect Day by Day

In the trials that showed benefit, participants started lozenges within 24 hours of the first symptoms and kept taking them throughout the waking day. The result was a cold that resolved roughly two days sooner on average, not a cold that disappeared overnight. Starting late, skipping doses, or using lozenges with zinc-binding additives all reduce the chance of seeing that effect. A daily zinc tablet or capsule works on a much longer timescale, gradually maintaining or restoring zinc status over weeks.

How Much Elemental Zinc Is in a Zinc Lozenge?

The amount varies by product, and many lozenges contain somewhere in the range of about 13 to 23 mg of elemental zinc each. The label should state the elemental zinc per lozenge, not just the weight of the zinc salt, because zinc acetate and zinc gluconate contain different proportions of actual zinc. Knowing this figure lets you estimate your daily total during a cold and keep the course short.

How to Choose the Right Zinc Formulation

Not all zinc supplements are equivalent either. The systemic bioavailability of different zinc compounds varies meaningfully and affects how well a supplement corrects deficiency and supports ongoing immune function.

Zinc picolinate and zinc bisglycinate, a chelated form, are generally considered among the best-absorbed options, making them good choices for correcting deficiency and maintaining adequate zinc status. Zinc citrate and zinc gluconate absorb reasonably well and are widely available. Zinc oxide, found in many low-cost multivitamins, is less well absorbed and is a weaker choice for raising zinc status.

The form of individual vitamins and minerals determines how much actually reaches the tissues that need them, and zinc is a clear example. The elemental zinc content on a label tells you the total zinc present, but the compound it is bound to determines how much your body can actually use.

What to Look for on a Zinc Lozenge Label

The best zinc lozenges share a few label features that line up with the research:

• Zinc form: Zinc acetate or zinc gluconate listed as the active ingredient
• Elemental zinc per lozenge: Clearly stated, so you can track your daily total
• Inactive ingredients: No citric acid, tartaric acid, mannitol, or sorbitol, which bind zinc ions
• Format: A lozenge designed to dissolve slowly, not a chewable tablet or a nasal product

For a daily zinc supplement, check the elemental zinc amount per tablet or capsule, choose a well-absorbed form such as picolinate, bisglycinate, or citrate, and look at whether your multivitamin already contains zinc so you do not double up.

Zinc Supplement Forms Compared: Citrate, Picolinate, Gluconate, and Oxide

When people move from lozenges to a daily supplement, the next question is which form of zinc to buy. The table below compares the forms you are most likely to see on tablets and capsules, based on the absorption differences described above.

Is Zinc Citrate a Good Choice?

Zinc citrate is a practical middle ground. It absorbs reasonably well, is widely available in tablets and capsules, and is often less expensive than picolinate or bisglycinate. It is a sensible daily option for most adults, but it is not the form to look for in a cold lozenge, since citrate-based ingredients can bind zinc ions in the mouth. For lozenges, stick with zinc acetate or zinc gluconate.

Zinc and Long-Term Immune Resilience

While lozenges address the acute cold scenario, long-term immune health depends on sustained adequate zinc status. Zinc is required for the development and activation of T cells, natural killer cells, and neutrophils. It regulates inflammatory cytokine production and is essential for the thymic function that produces immune cells throughout life.

Zinc deficiency impairs virtually every branch of the immune system. Even mild, subclinical deficiency that would not show up as a clinical diagnosis can reduce immune responsiveness, increase susceptibility to infection, and slow recovery. Older adults are particularly at risk because zinc absorption decreases with age and dietary intake often falls short of requirements.

Zinc supplementation plays its most meaningful long-term role within a broader nutritional framework, particularly for adults managing age-related immune decline. Our guide to when to start immune supplements covers how to time that kind of daily support around the seasons.

Daily Zinc Requirements and Who Is Most at Risk of Deficiency

The recommended daily intake of zinc is 8 mg per day for adult women and 11 mg per day for adult men, according to the NIH Office of Dietary Supplements. The tolerable upper intake level for long-term daily use is 40 mg per day. Most adults who eat a varied diet that includes meat, shellfish, legumes, and nuts meet the basic requirement, but several populations are at consistent risk of insufficiency.

Vegetarians and vegans are at higher risk because plant-based zinc sources contain phytates that reduce bioavailability. Older adults absorb zinc less efficiently and often eat less. People with gut conditions including inflammatory bowel disease or celiac disease have impaired zinc absorption regardless of dietary intake. People who drink alcohol heavily excrete more zinc in urine than those who do not.

Gut health is directly relevant here, since a compromised gut lining reduces zinc absorption and compounds the deficiency risk in people who are already nutritionally vulnerable. Our article on the signs your gut lining needs repair explains what to watch for.

Best Food Sources of Zinc

Food remains the foundation of zinc status, and a few foods supply far more than others. Oysters are the richest source by a wide margin, followed by red meat, poultry, crab, and lobster. Beans, nuts, seeds, whole grains, dairy, and fortified breakfast cereals also contribute, although zinc from plant foods is less well absorbed because of phytates. If your diet regularly includes these foods, a lower-dose supplement or none at all may be enough.

Taking Zinc With Iron, Calcium, and Magnesium

Zinc does not only compete with copper. Several other minerals can affect how much zinc you absorb, which matters if you take a multivitamin or more than one single-mineral supplement. Spacing them out is usually enough to avoid problems.

Iron and Calcium

High-dose iron supplements can reduce zinc absorption when the two are taken together on an empty stomach, and calcium may have a similar effect at higher doses. If you take iron or calcium as separate supplements, take zinc at a different time of day. Iron and zinc together in food are much less of a concern than high-dose supplements.

Magnesium and Fiber

Very high zinc intakes can interfere with magnesium absorption, which is another reason to stay within sensible daily amounts. Many people take magnesium in the evening, as covered in our guide to magnesium for sleep, which naturally separates it from a morning zinc dose. High-fiber foods rich in phytates, such as whole grains and legumes, also lower zinc absorption, so taking zinc away from those meals can help.

Zinc's Relationship With Copper and Why It Matters

Zinc and copper share the same intestinal absorption pathway and compete for uptake. This is the most clinically significant safety consideration in zinc supplementation. When zinc intake is chronically elevated, copper absorption falls, and copper deficiency produces consequences that are both serious and slow to appear: anemia, neurological symptoms, reduced HDL cholesterol, and impaired bone health.

This interaction is a key reason the 40 mg daily upper limit exists and why it applies to total zinc from all sources, not just supplements. Someone taking a zinc supplement daily who also has a multivitamin containing zinc and eats a zinc-rich diet can exceed this threshold over time without realizing it.

For people who supplement higher doses of zinc long-term, adding a small amount of copper, often 1 to 2 mg daily, is commonly recommended to prevent the depletion that develops over months of zinc-dominant supplementation. Because individual compounds can interact in ways that are easy to miss, our guide on whether immunity supplements are safe offers useful context for avoiding a secondary deficiency while addressing a primary one.

Side Effects, Drug Interactions, and Safety

Both forms of zinc are well tolerated by most adults at appropriate doses, but each has its own side effect profile, and zinc interacts with several common medications. Knowing these in advance makes it easier to choose the right form and use it safely.

Zinc Lozenge Side Effects

The most common complaints with zinc lozenges are a bad or metallic taste, mouth irritation, and nausea, which are the main reasons people stop using them in trials. Because lozenges are used frequently over several days, these effects are more noticeable than with a once-daily supplement. Taking lozenges after a light snack rather than on a completely empty stomach can help with nausea, as long as you avoid eating or drinking for a short time after each one.

Zinc Supplement Side Effects

Daily zinc supplements most often cause nausea or stomach upset, especially when taken on an empty stomach. Taking the tablet or capsule with food usually solves this. Long-term intake above the upper limit can lead to copper deficiency and lower HDL cholesterol, which is why staying within a sensible daily dose matters more than taking more.

Avoid Zinc Nasal Sprays and Gels

Zinc lozenges should not be confused with intranasal zinc products. The U.S. Food and Drug Administration has warned that zinc nasal sprays and gels have been linked to loss of the sense of smell, which can be long-lasting. If you want zinc for a cold, a lozenge that dissolves in the mouth is the form supported by research.

Drug Interactions

Zinc can reduce the absorption of quinolone and tetracycline antibiotics, so take the antibiotic at least 2 hours before or 4 to 6 hours after zinc. Zinc can also reduce the absorption of penicillamine, a medication used for rheumatoid arthritis, and thiazide diuretics can increase how much zinc your body loses in urine. If you take any prescription medicine, ask your doctor or pharmacist before adding zinc lozenges or a zinc supplement.

Sleep, Stress, and Zinc Depletion

Zinc status is not just determined by diet. Psychological stress and poor sleep both affect the immune competence that zinc supports, and stress has been linked to increased zinc losses, which is one way chronic stress may gradually wear down immune function even in people eating adequate diets.

Poor sleep compounds this independently. The overnight window is when many immune functions are most active, including cytokine release and immune cell proliferation, and sleep deprivation reduces these processes.

That is why sleep and stress management belong in any nutritional immune support plan, and our sleep and stress reduction tips cover practical ways to address both. Supplementing zinc while ignoring these drivers is like refilling a bucket with a hole in it.

Zinc Alongside Other Key Immune Nutrients

Zinc does not operate in isolation in the immune system. Several nutrients work alongside it through distinct but complementary mechanisms, and combining them provides broader immune support than any single nutrient on its own.

Vitamin C supports collagen synthesis in mucosal barriers, acts as an antioxidant in immune cells, and supports the neutrophil function that zinc also depends on. Vitamin D regulates the expression of many immune genes and is one of the most common immune-relevant deficiencies in northern populations. Elderberry has been studied for reducing cold and flu duration and severity in several controlled trials.

Our article on elderberry for immune support covers this in detail and positions elderberry as a natural complement to zinc during the acute cold phase rather than an alternative to it.

Selenium, another trace mineral, supports thyroid function and antioxidant defense in immune cells and is frequently low alongside zinc in people with limited dietary variety.

If you would rather cover these nutrients in one daily step, the NuLifeSpan Immune Pack combines vitamin C and zinc with elderberry extract, vitamin D3, and antioxidant support in a pre-portioned daily pack, designed for everyday immune support rather than mega-dosing.

What Zinc Lozenges Cannot Do

Understanding what zinc lozenges cannot do is as practically important as understanding what they can. Lozenges do not prevent colds before symptoms start. Trials that examined zinc for cold prevention have not found a consistent benefit, and there is no good evidence that starting lozenges at the beginning of cold and flu season or at first exposure to a sick person reduces infection risk.

Lozenges are not proven to treat influenza. The research on zinc lozenges focuses on the common cold, much of which is caused by rhinoviruses, and influenza is a different virus that enters cells through different pathways. There is no good evidence that zinc lozenges shorten the flu the way they can shorten a cold.

Lozenges are also not a good fit for children. Evidence in children is limited and mixed, and the doses used in adult cold trials are far above children's upper intake limits, creating a risk of side effects without clear evidence of benefit. Our guide to immune support for kids covers safer approaches.

Practical Lozenge Protocol When a Cold Starts

For adults who want to use zinc lozenges correctly during an acute cold, the research points to a specific protocol that maximizes the chance of benefit.

Use zinc acetate or zinc gluconate lozenges exclusively. Avoid formulations containing citric acid, tartaric acid, mannitol, or sorbitol, which bind ionic zinc and reduce the effect. Start at the very first symptom, ideally within the first few hours but certainly within 24 hours. Take one lozenge every two to three hours while awake, allowing it to dissolve fully in the mouth rather than chewing or swallowing it. Avoid eating or drinking for at least 15 minutes after each lozenge to maintain zinc contact time with the throat.

Use lozenges only for the duration of the cold, typically up to about a week. The trials that showed benefit used total daily amounts above the 40 mg upper limit, which is set for long-term daily intake, not short courses. Because of this, keep lozenge use short, pause any separate zinc supplement while you are using them, and speak with your doctor first if you are pregnant, take prescription medication, or plan to use them for longer.

Lozenges also work best in people who already have good baseline immune health from consistent nutrition and lifestyle, as our guide to proactive health strategies explains, rather than as a shortcut for people whose immune resilience is already depleted.

Long-Term Zinc Supplementation for Immune Support

For adults whose goal is long-term immune support rather than acute cold treatment, a daily zinc supplement at a dose of 8 to 15 mg of elemental zinc is appropriate for most people without diagnosed deficiency. Those with confirmed deficiency, absorption issues, or significant risk factors may benefit from higher doses under medical guidance.

The best forms for systemic absorption are zinc picolinate, zinc bisglycinate, and zinc citrate. Taking the supplement with food reduces the mild nausea that some people experience on an empty stomach, though absorption is slightly better away from meals high in phytates such as whole grains and legumes. If taking higher doses for extended periods, including a small copper supplement helps prevent the competitive depletion that develops over time.

A nutrition-first approach makes zinc supplementation most meaningful, particularly for adults whose immune concerns reflect broader nutritional gaps rather than isolated zinc insufficiency. Our guide to nutrition and healthy eating covers that foundation.

Buying and Storing Zinc Lozenges and Supplements

Zinc lozenges and zinc supplements are both widely available, but quality and storage affect how well they work. A few simple checks help you get a product that matches what the research supports.

Where to Buy Zinc Lozenges and Supplements

Zinc lozenges are usually found in the cold and flu section of pharmacies, while zinc tablets and capsules sit with vitamins and minerals in pharmacies, supplement stores, and online shops. Wherever you buy, choose products that list the zinc form and elemental zinc amount clearly, and look for independent third-party testing seals, which confirm that the product contains what the label says. Your pharmacist can also help you check a lozenge's inactive ingredients. If you travel often and want to keep zinc on hand, our guide to immune support for frequent travelers covers what to pack.

How to Store Zinc Lozenges

Store zinc lozenges and supplements in a cool, dry place in their original sealed container, away from heat and humidity, which can soften lozenges and degrade tablets. Keep them out of reach of children, since flavored lozenges can look like candy and the adult doses are too high for children. Check the expiration date before cold season so you are not relying on an old pack when symptoms start.

Zinc Lozenges or Zinc Supplements: Which Should You Choose?

The right choice depends on your goal, and many adults end up using both at different times. Use this as a quick decision guide:

• Choose zinc lozenges if you feel the first signs of a cold and can start within 24 hours, and you are an adult who can use them for a short course.
• Choose a zinc supplement if your goal is daily immune support, you eat little meat or seafood, you are over 60, or you have a condition that affects absorption.
• Use both, one at a time, by taking a daily supplement year-round and switching to lozenges for a few days when a cold starts, pausing the supplement during that time.
• Talk to your doctor first if you are pregnant, take antibiotics or other prescription medicine, or are considering zinc for a child.

So are zinc lozenges better than zinc pills? For shortening a cold, yes, because pills do not deliver zinc to the throat. For everyday immune support and preventing deficiency, a daily tablet or capsule is the better tool.

Frequently Asked Questions

Do zinc lozenges actually shorten colds?

Yes, when used correctly. Clinical trials show that zinc acetate or zinc gluconate lozenges started within 24 hours of first symptoms can shorten a cold by roughly two days. The benefit depends on using lozenges without additives that bind ionic zinc and on starting early. Flavored lozenges with citric acid or sorbitol tend to fail in trials because these additives neutralize the zinc before it can act.

What is the difference between zinc lozenges and zinc supplements?

Zinc lozenges dissolve in the mouth and release ionic zinc locally in the throat, where it is thought to interfere with rhinovirus attachment and replication. They are designed for short-term cold treatment. Zinc supplements are swallowed and absorbed through digestion, delivering zinc throughout the body to correct deficiency and support immune cell function. The delivery method determines the effect, which is why research on one form cannot be applied to the other.

Are zinc lozenges better than zinc pills?

For shortening a cold, lozenges are the better option because they deliver zinc directly to the throat. For long-term immune support and preventing zinc deficiency, a daily zinc tablet or capsule is more appropriate. They serve different purposes rather than competing with each other.

How much zinc is safe to take per day?

The tolerable upper limit for adults is 40 mg per day from all sources combined for long-term daily use, including food, multivitamins, and supplements. Consistently exceeding this level can reduce copper absorption and lower HDL cholesterol. Cold trials used higher amounts from lozenges for a short period only, so keep lozenge courses to about a week and check with your doctor if you have health conditions or take medication.

Can you take zinc lozenges and zinc supplements together?

It is best to pause your daily zinc supplement while you use lozenges for a cold, since lozenges already provide a large amount of zinc. Once the cold has passed, return to your usual daily supplement. If you supplement higher doses of zinc long-term, adding a small amount of copper helps prevent depletion.

What is the difference between zinc acetate and zinc gluconate?

Both are zinc salts used in cold lozenges. In a 2017 meta-analysis, zinc acetate lozenges shortened colds by about 40 percent and zinc gluconate lozenges by about 28 percent, but the difference was not statistically significant. A well-formulated lozenge of either type, without citric acid or similar additives, is a reasonable choice.

What are the side effects of zinc lozenges?

The most common side effects are a bad or metallic taste, mouth irritation, and nausea. These are usually mild and stop when you stop the lozenges. Never use zinc nasal sprays or gels, which have been linked to loss of smell.

Why do some zinc lozenges not work?

Many lozenges that failed in trials contained additives such as citric acid, tartaric acid, mannitol, or sorbitol. These compounds bind ionic zinc in the mouth before it can act in the throat. A lozenge can contain the correct elemental zinc dose and still have little effect if its inactive ingredients neutralize the zinc, so reading the inactive ingredient list matters as much as the dose.

Is zinc good for immune health year-round?

Yes. Zinc is required for the development and function of T cells, natural killer cells, and neutrophils, and for regulating inflammatory cytokine production. Maintaining adequate zinc status year-round supports baseline immune resilience and recovery when illness does occur. For non-deficient adults, 8 to 15 mg of elemental zinc daily in a well-absorbed form such as zinc picolinate or zinc bisglycinate is a common range.

Can zinc lozenges prevent colds?

No. Trials that examined zinc for cold prevention in healthy adults have not found consistent evidence of benefit. Zinc lozenges work by acting on the virus early in an infection, so the evidence supports starting them at the very first symptom, not before illness begins.

What foods are high in zinc?

Oysters are the richest food source of zinc. Red meat, poultry, crab, lobster, beans, nuts, seeds, whole grains, dairy, and fortified cereals also provide zinc, though zinc from plant foods is less well absorbed.

How quickly do zinc lozenges work?

Zinc lozenges do not give instant relief. Started within 24 hours of the first symptoms and used throughout the day, they can shorten a cold by roughly two days, so most people notice the effect as an earlier recovery over several days.

Do zinc lozenges help a sore throat?

They can be part of your approach when a sore throat is the first sign of a cold, because they act in the throat early in the infection. Their proven benefit is a shorter cold overall rather than numbing throat pain, and some people find the taste irritating at first.

How much elemental zinc is in a zinc lozenge?

It varies by product, with many lozenges containing roughly 13 to 23 mg of elemental zinc each. Check the label for the elemental zinc amount per lozenge so you can track your daily total during a cold.

Is zinc citrate good for daily use?

Yes. Zinc citrate absorbs reasonably well and is a practical, widely available option for a daily supplement. It is not recommended for cold lozenges, where zinc acetate or zinc gluconate without citric acid is the better choice.

Should you take zinc with iron or calcium?

It is better to take zinc at a different time from high-dose iron or calcium supplements, since they can reduce zinc absorption when taken together. Minerals that come together in food are much less of a concern.

Is zink the same as zinc?

Yes. Zink is the spelling used in several European languages, including German and Dutch, for the same mineral. Products labeled zink contain zinc, so the same forms, doses, and safety limits apply.
