In this blog, I will write about zinc and its overall benefits. In my personal experience, zinc has benefited not just my overall health but also my progress in the gym. After reading this blog, you will be informed about all the benefits you can get with zinc, the best zinc supplement for you, and frequently asked questions about zinc.
Best Overall Zinc Supplement for Overall Health and Skin Support
Thorne Zinc Picolinate is a great overall choice for individuals seeking to address one of the following needs: adults with low to moderate zinc deficiencies or inadequate dietary intake, those focusing on immune support, those with absorption challenges, and those looking to support skin and wound healing. Why is it considered the best overall for overall health and skin support? Zinc picolinate is superior in bioavailability compared to other forms of zinc, such as zinc oxide, sulfate, and gluconate. This makes it more suitable to take as a supplement for any of the reasons listed above.
Best Overall Zinc Supplement for Gym Performance and Testosterone Support
OptiZinc (zinc monomethionine) is an excellent choice for gym-goers and anyone looking for testosterone support. This is because OptiZinc also has high bioavailability and a strong balance of absorption, making it effective and suitable for long-term use, and superior to gluconate and sulfate. OptiZinc is great because its components support testosterone production, muscle protein synthesis, and energy levels, which are key for athletes who often lose zinc through sweat and need it for hormone balance and performance. Studies show that zinc can boost testosterone levels post-exercise, especially for individuals with a deficiency. This makes OptiZinc a high-quality supplement for gym-goers, athletes, or those seeking testosterone support.
Best Budget Zinc Supplement
Holland & Barrett Zinc 15mg 120 Tablets
Holland & Barrette zinc tablets are an amazing budget option, costing approximately 6-10p per serving. It is a great entry-level option for most people, providing a decent dose of 15mg (slightly above the recommended dose for adults but without excess risk). Zinc gluconate (a type of zinc in this product) offers decent absorption, still better than oxide. Holland & Barrett is a well-known and trusted brand, with 4.5-star reviews on Amazon, especially in the UK. This brand of Zinc is strongly recognised for its immune support and everyday wellness. If you live in the UK, you can use the Holland & Barrett ‘near me’ search to find a store near you if you prefer to buy in person. This product is also vegan and vegetarian-friendly. This makes the product a reliable, low-risk pick for budget-focused individuals
Best Alternative to Our Best Overall Zinc Supplement
Now Foods zinc is a great alternative to the best overall, and can be used for any of your goals. Zinc glycinate has high bioavailability and is chelated, which means it is better absorbed than in the budget options. Unlike regular zinc supplements, which usually have poor bioavailability, the chelated form ensures your body actually uses most of the zinc, preventing it from going to waste. This makes it suitable for effective immune support, skin health, and your overall wellness. Even though you are not meant to take most supplements on an empty stomach, including zinc, many users report no side effects, such as nausea or GI upset, whilst taking them on an empty stomach (Does Not Mean You Should Take On an Empty Stomach). This shows the quality of this supplement is good, as one of the biggest complaints that zinc supplements receive is stomach discomfort. NOW Foods is a reputable brand with third-party testing. The soft gel format of the supplement is convenient: the tablets are not large, so you don’t have to choke them down, and it is suitable for most diets (check allergens if needed). The ratings of the product are a consistent 4.7 stars from across thousands of reviews, users praising it, saying it improved their immunity, sleep, and provided noticeable boosts in their wellness
Best Zinc Supplement Under £10
Nutravita Zinc tablets offer unbeatable value with their massive supply: 365 Vegan tablets (6-12 months, depending on your daily dosage), making it one of the cheapest zinc options on the market (2-3p per day). Each tablet has 50mg of elemental zinc from zinc gluconate, which is highly absorbable and effective for most people. This supplement supports normal immune system function and the maintenance of many body systems, including bones, vision, hair, skin, and nails (backed by EFSA). Users openly state about the noticeable improvements in immunity, skin quality, stronger nails, and overall energy levels, a good all-rounder for everyone, including men, women, vegans and anyone who prioritises keeping their natural health whilst on a budget. This product is vegan-friendly, UK-made, and well-trusted, with batches tested for purity, reassuring buyers who worry about the reliability of supplements. With 4.5 stars from almost 1000 reviews, most people praise the value and results you get with this supplement; some mention the tablets are a bit larger, but not a problem with water, and, in general, the benefits outweigh the minor cons. Each dose contains 50mg, which is safe for short-term use or even occasional use. I recommend consulting a doctor first to avoid copper imbalances or excess. It’s great for boosting when you need. Some people consider this the best budget high-strength zinc in the UK in 2026.
Zinc Alternatives and Supplement Stacks to Consider
Alternative 1- Vitamin D3 4000IU
Vitamin D3 is a good alternative to zinc for immune support and testosterone boosting, especially in low-sun environments such as the UK. Some of the benefits of vitamin D3 include enhanced muscle growth, reduced fatigue after a workout, and support for bone health among people who do heavy lifting. The dosage is 4000 IU, which makes daily use okay and works well when stacked with gym routines for better recovery. Some of the product perks are that it is a vegetarian product, UK-made, and provides a supply for more than a year (400 tablets). Science studies show that testosterone levels can increase up to 20%, and also an increase in immune function. Warning, test your levels beforehand, some rare side effects include nausea if overdone. This product has high ratings (4.5+ stars) and is budget-friendly for beginners.
Alternative 2- Magnesium Glycinate 120mg
Magnesium glycinate is a good zinc alternative for muscle recovery, regulating testosterone levels, and even stress reduction post-gym. Some benefits include relief from delayed-onset muscle soreness (DOMS), improved sleep quality to support gains, and even cortisol control for better performance. The product’s dosage is 120mg (evening dose), making it gentle on the stomach and ideal for intense athletes and gym-goers. Some of the perks of the product include being hypoallergenic (lower risk of causing an allergic reaction), no fillers, a bioavailable glycinate form, and 90 capsules that can last you up to 3 months. Science studies show benefits for athletes’ endurance and hormone balance. Warning, signs of deficiency such as cramps or fatigue, and also avoid when taking certain meds (Advised to consult with a Doctor if needed). This Magnesium Glycinate brand is premium and has 4.7 stars from thousands of reviews, making it a trustworthy product.
Alternative 3- Ashwagandha KSM-66 1500mg
Ashwagandha KSM-66 is a herbal alternative to zinc for natural testosterone boosting and adaptogenic stress relief in fitness. Some of the benefits include increased strength and endurance (up to a 15% increase in testosterone), aid in fat loss, and enhanced focus in the gym. Dosage of this supplement is 1500mg daily (best to split doses throughout the day). Cycle the product: 8-12 weeks on and 1-4 weeks off for optimal results. KSM-66 extract, which is potent, root-only, vegan, and non-GMO, has enough tablets for up to 6 months and is the perk of this product. Science shows clinical trials on muscle gains and anxiety reduction. Warning: possible mild upset. This product is the #2 bestseller in its category, having 4.5 stars from more than 4000 ratings.
Stack Consideration 1- Optimum Nutrition, ZMA
Optimum nutrition ZMA is a stack including zinc, magnesium, and vitamin B6, this stack works well for night time recovery. Some of the benefits of this stack include boosting testosterone levels, improving sleep quality, and accelerating muscle recovery for lifters. The recommended dosage is 3 capsules before bedtime on an empty stomach; it is best suited for men and women aged 30 or older. This product is produced in the EU, is easy to swallow, and is from a trusted brand. It comes in 90 capsules, which are for approximately 30 servings. Scientific studies show improved strength and reduced fatigue in athletes. Warning: vivid dreams are possible; monitor for any mineral imbalances. This product is favoured by athletes, has a 4-4.6-star rating, and has strong sports nutrition demand.
Stack consideration 2- Biotin + Zinc
Biotin and Zinc make a great stack for health, beauty, and fitness. Biotin is known for supporting hair growth, stronger nails, and glowing skin by aiding the production of a protein called keratin, which is found in hair and nails. This can be appealing to some gym lifters who want to look as good as they feel, preventing brittle nails from heavy lifting and maintaining healthy skin and hair despite sweat and stress. Biotin is a B vitamin that helps convert carbs, fats, and proteins into energy, which is crucial for intense gym sessions. Also improving endurance and post-workout recovery by indirectly supporting protein synthesis, helping rebuild muscle tissue after training. Biotin itself will not dramatically increase testosterone levels or muscle growth like zinc and magnesium do, but it contributes to overall energy metabolism and can help if you are deficient, which is rare in balanced diets. Some studies show that B vitamins (including Biotin) aid muscle repair and performance in active individuals. This stack is best for lifters dealing with hair thinning from stress and intense training, brittle nails, or poor skin from sweat. Also, it is great for women in fitness for hormonal balance, or for anyone on a restrictive diet, such as a low-carb or keto diet, where biotin intake often dips. Stacking this with Zinc is an excellent combo, as zinc supports immune, testosterone, and muscle recovery, while biotin enhances appearance and energy. This is the beauty booster every lifter needs. Remember to consult with a professional, especially if you are on medication. This brand is trusted, with over 95% positive ratings from over 500 customers.
Stack Consideration 3- Selenium + Zinc
Selenium and Zinc are both essential trace minerals, and are commonly stacked together for overall health and immune support, they both work differently but compliment eachother nicely. Selenium complements zinc because zinc supports immune cell function, skin health, and hormone balance. Selenium supports antioxidant enzymes in the body and also the thyroid gland function. Together, they help cover a wide range of micronutrient needs without overlapping. This stack is useful for people with a low dietary intake of selenium, individuals under high levels of stress or intense training, or those focused on immune resilience and general well-being. Selenium has a narrow safe range and is not safe to exceed the recommended doses, long term high intake is not adviced either. Best to take zinc and selenium together within the label guidelines, or consult a professional.
What is the best type of zinc supplement?
Zinc form matters a lot depending on what your goal is; each different chemical form of zinc affects the absorption, tolerance and bioavailability. Common forms of zinc include OptiZinc (zinc monomethionine), zinc picolinate, zinc glycinate, zinc citrate, zinc gluconate, and zinc oxide (lowest absorption). The best zinc sources for general health and daily use are zinc picolinate and zinc glycinate. This is because these forms are well absorbed, easier on the stomach, allow daily use, and support immune system function, skin health, and general well-being. The best zinc for gym performance or testosterone support would be OptiZinc, which is good because it has high absorption, balanced bioavailability and retention, is helpful for people who sweat a lot (you lose zinc when you sweat), and supports hormone balance. Each form of zinc affects how much zinc your body actually absorbs and how likely you are to experience side effects. I suggest sticking to the label directions and not exceeding the safe daily intake in the long term without consulting a professional.
Is OptiZinc better than zinc citrate?
OptiZinc is generally better absorbed, but zinc citrate is more affordable and still effective. This means that which one is better depends on your goals and budget, not that one is good and the other bad. OptiZinc is bound to an amino acid, which improves absorption and retention, while zinc citrate is a simpler salt form, with decent absorption but is not as efficient. Bioavailability and retention are where OptiZinc tends to have the edge. This means OptiZinc is better for lifters and athletes, people who sweat a lot and are focused on testosterone support and recovery. Zinc citrate makes more sense if you are a budget-focused user, a beginner trying zinc for the first time, or for general immune or everyday health support. Note that both forms are effective when used within recommended doses, and best to consult with professionals. If this answered your question, you can scroll up to Best Overall Zinc Supplement for Gym Performance and Testosterone Support or Best Zinc Supplement Under £10.
What’s the difference between zinc methionine and zinc citrate?
Zinc methionine is zinc bound to an amino acid (methionine), and Zinc citrate is zinc bound to citric acid. Depending on how it is bound, it affects absorption and retention. Zinc methionine (including OptiZinc) is chelated, meaning it is generally better absorbed and tends to remain in the body longer. Zinc citrate has lower absorption and lower retention than methionine. Chelated forms like merthionine are often more gentle on the stomach; citrate is usually well tolerated but can cause mild nausea in some people; response varies by individual.
Is biotin and zinc good for hair?
Zinc supports hair follicle function, protein synthesis, and scalp and skin health (studies show Zinc deficiency has been linked with hair thinning). Biotin plays a role in keratin production (the protein in hair and involved in protein synthesis) and in hair strength and structure. I previously recommended this stack for certain people, so feel free to scroll up to Stack consideration 2: Biotin + Zinc. Results depend on your nutrient status; hair changes can take weeks to months and are not effective for genetic hair loss.
Does zinc help with skin health?
Zinc plays an important role in skin health. It supports normal skin function, especially when dietary zinc intake is low, but it does not mean it is a treatment. Zinc is involved in cell growth and repair, supports wound healing, plays a role in collagen synthesis, and helps maintain the skin barrier. For skin improvements to kick in, it takes time, and it works best as part of your overall nutrition. Your results vary based on your diet and lifestyle
Should you take selenium and zinc together?
Selenium and Zinc can be taken together, and they complement each other when used appropriately. Zinc supports immune cell function, skin health, and hormone balance. On the other hand, selenium supports antioxidant enzymes and normal thyroid function, and together they help cover a wide range of micronutrient needs, rather than overlapping. I recommended this as a stack to take. Scroll up to Stack Consideration 3- Selenium + Zinc to find out more.
How much zinc should you take daily?
Daily zinc varies; it depends on an individual’s diet, age, training level, and whether a deficiency is present. The typical daily intake for adults is 15-30mg; higher doses are sometimes used, but only for the short term. For lifters and athletes, zinc dosages may need to be slightly higher due to heavy training, which causes sweating ( zinc is lost through sweat), but it is still recommended to remain within the given limits. I advise taking zinc with food to reduce symptoms such as nausea; check multivitamins if you take any to avoid stacking too much; and, finally, consistency matters more than timing.
