Why Glycinate is Better Than Other Forms of Zinc
The Underrated Mineral for Immune and Hormonal Health
Zinc is one of those quiet achievers in the world of micronutrients. It plays an essential role in dozens of physiological processes: from immune defence to hormone regulation, skin repair and reproductive health.
Yet, many people don’t realise they may be deficient or are taking forms of zinc that offer poor absorption. In this post, we’ll unpack why zinc matters, the evidence behind its most powerful health benefits, the best time to take zinc and how Veritroo’s Zinc Bisglycinate Capsules deliver this essential mineral in a form your body can truly use.
What is Zinc and Why Is It Essential?
Zinc is a trace mineral your body needs in small amounts, but for over 300 enzyme functions, that tiny amount makes a big impact. It’s involved in:
- Wound healing
- Healthy Reproductive Hormones
- Sperm Health
- Reproductive System Health
- Immune function
- Antioxidant protection
- Skin health
Because your body doesn’t store zinc long term, daily intake through food or supplementation is essential.
Which Form of Zinc is Best to Take?
Not all zinc supplements are created equal. Many supplement brands use forms like zinc oxide or zinc sulphate, which are poorly absorbed and more likely to cause stomach upset. These are cheaper to manufacturer but unfortunately offer less benefits to you.
Scientific studies show chelated forms, especially zinc bisglycinate (also known as zinc glycinate), offer superior absorption and gastrointestinal tolerance (Crawford et al., 2022; Momen-Heravi et al., 2017). It is why, at Veritroo, we choose to use Zinc bisglycinate.
Top Health Benefits of Zinc Glycinate
Let’s look at some areas where zinc makes a difference and the evidence behind it:
1. Supports Wound Healing
Randomised controlled trials (RCTs) demonstrate that zinc supplementation significantly improves wound healing in patients by promoting cell repair, collagen synthesis and immune function at the site of the injury. A higher dose of 50mg is recommended for wound healing. (Momen-Heravi et al., 2017; Song et al., 2020; Smith et al., 2022).
2. Enhances Immune Function
Zinc is essential for immune cell development and function. Systematic reviews found zinc enhances immune response and reduces the duration of colds, especially in those who are zinc-deficient (Crawford et al., 2022; Nault et al., 2024). A higher dose of 50mg taken within the first 24 hours of cold symptoms may reduce the length of a cold by up to 2 days.
3. Supports Healthy Reproductive Hormones
Zinc plays a vital role in hormone regulation for both men and women. Clinical studies have show zinc supplementation improves testosterone levels in men and supports hormone levels in women with PCOS and other reproductive disorders (Nasiadek et al., 2020; Liger Te et al., 2023).
4. Supports Sperm Health
Zinc supports sperm health by contributing to normal sperm formation, motility and overall sperm quality. Studies show zinc supplementation can significantly improve sperm count, motility, and morphology particularly in men with low seminal zinc levels (Dimitriadis et al., 2023; Zhao et al., 2016).
5. Antioxidant Protection
Zinc acts as a powerful antioxidant by helping to reduce free radicals formed in the body which can cause cellular damage. Clinical studies show that zinc supplementation supports oxidative stress reduction by increasing antioxidant capacity and lowering markers of inflammation and lipid peroxidation (Crawford et al., 2022; Mazaheri Nia et al., 2021).
6. Maintains Skin Health
Zinc plays an essential role in maintaining healthy skin by supporting skin structure and modulating inflammatory responses. Clinical Research shows that zinc can benefit individuals with inflammatory skin conditions such as acne, atopic dermatitis, and rosacea (Grey et al. 2019; Dhaliwal et al. 2020; Laing et al. 2020). It is associated with improved skin elasticity, hydration and barrier function.
Zinc Benefits for the Immune System
Perhaps the most well-known benefit, zinc’s impact on immunity is supported by large-scale research:
- A Cochrane review involving over 8,500 participants concluded zinc may reduce cold duration by around 2 days (Nault et al., 2024).
- Zinc improved immune response and reduced infection rates in older adults taking 45 mg/day (Crawford et al., 2022).
- It also supports white blood cell activity and regulates inflammation, both key in preventing and managing illness.
Zinc’s Role in Hormonal Health
Zinc is key for hormonal regulation across all stages of life.
For Men's Health:
- Zinc deficiency is associated with low testosterone and reduced fertility.
- Supplementation can improve sperm quality and healthy reproductive hormones (Liger Te et al., 2023).
For Women's Health:
- Zinc helps regulate oestrogen, progesterone, and androgens.
- In women with PCOS or dysmenorrhea, zinc supplementation improves insulin resistance, hormone levels, and reduces menstrual pain at a clinically researched dose of 50mg of elemental zinc (Nasiadek et al. 2020)
- Menopausal and postmenopausal women also benefit as zinc improves sexual function and testosterone levels (Mazaheri Nia et al., 2021).
When is the Best Time to Take Zinc Glycinate?
The best time to take zinc supplements is 1 hour before or 2 hours after meals. This helps your body absorb it more efficiently without interference. Some people may experience nausea when taking zinc without food. If that's you, take it with a light, low-phytate meal like a piece of fruit or some lean protein. Avoid high-fibre or grain heavy meals during this time.
Timing matters with other minerals. Don't take zinc alongside magnesium, calcium or iron as these all compete for absorption in the gut. Take zinc in the morning and schedule other minerals for later in the day. This simple timing trick helps maximise your nutrient absorption and supports overall effectiveness.
Are You at Risk for Zinc Deficiency?
Common risk factors include:
- High stress or frequent infections
- Plant-based diets
- Digestive disorders (e.g. Crohn’s, coeliac)
- Heavy sweating (athletes)
- Pregnancy and breastfeeding
Symptoms may include:
- Frequent illness
- Poor wound healing
- Acne, dermatitis or dry skin
- Hormonal issues
- Reduced libido or fertility
- Loss of smell or taste
What is the Recommended Zinc Dose?
The ideal zinc dose depends on your individual health goals and whether you are using it for short term therapeutic support, or long term maintenance.
For short term use, such as supporting wound healing or reducing the duration of the common cold, a higher dose of 50mg of elemental zinc per day (2 capsules) may be appropriate. This level of support is designed to target acute needs over a limited period.
For ongoing daily wellness, a maintenance dose of 25mg of elemental zinc per day (1 capsule) is generally sufficient to help support immune function, skin health and healthy reproductive hormones.
As with any supplement, it is important to consult your healthcare professional to determine the right dose for your personal needs and to avoid potential side effects from long term high dose use.
Why Veritroo Zinc Stands Out

Conclusion
Zinc might be a trace mineral, but its health benefits are anything but minor. From strengthening immunity to regulating hormones and improving skin health, zinc deserves a place in your daily routine.
But remember it's not just what you take, it’s what your body absorbs. That’s why bioavailable forms like Zinc Bisglycinate are the smarter choice for long-term health.
Always read the label and follow directions. Consult a healthcare professional to determine if this product is right for you. Supplements should not replace a balanced diet.
