Ever wondered why your skin flares up, your child catches colds easily, or your teenager struggles with mood swings? Your body might be quietly calling out for more zinc.
Zinc is a tiny but mighty mineral that helps your body run smoothly behind the scenes. It supports your immune system, helps wounds heal, maintains healthy skin, and is vital for growth, brain health, and even mood stability.
In this article, we break down six powerful ways zinc supports your health, no matter your age or stage.
Why Zinc is Crucial for Everyone
Zinc is the second most common trace mineral in your body, and it’s a busy one. It helps over 300 enzymes do their jobs and supports about 1,000 transcription factors, which are like little switches that turn on important healing and repair processes.¹
That means zinc plays a key role in keeping things running smoothly, from making DNA to balancing hormones, supporting immune function, skin repair, brain development, and even our sense of taste.¹
Why Might You Need Zinc Supplements?
Even on a wholefood diet, zinc deficiency is surprisingly common. Australian soils are naturally low in zinc, and food processing further strips away this crucial mineral.² Research shows that many Australians, especially vegetarians and women, fall short of recommended zinc levels.³ Supplements can help bridge that gap.
How Long Should You Take Zinc, and How Much?
The amount you need depends on your age and stage⁴:
• Children (1-13 years): 3-6 mg/day
• Teenagers (14-18): 7-13 mg/day
• Adults: 8–14 mg/day
• Pregnant women: 10-11 mg/day
• Upper safe limit in adults: 40 mg/day.
Short-term supplementation (up to 6 weeks) at higher doses (25-40 mg/day) may be recommended during acute illness or for wound healing. Long-term supplementation should stay below the upper limit unless under practitioner guidance.
Be sure to follow the advice of a Healthcare Practitioner, as well as using well-absorbed forms, like zinc bisglycinate found in Meta Zinc with Vitamin C Powder.
A is for Adolescents and Kids for Growing Bodies
Zinc is like the scaffolding of a building; it helps hold everything together while it grows. For kids and teens, zinc plays a big role in helping their bodies and minds develop properly.
In children, zinc supports brain development, a strong immune system, and physical growth. One study showed that kids who took 5-10 mg of zinc each day had better motor skills and overall development.⁵,⁶
In 100 kids aged 8 to 13, 15 mg of zinc taken over 3 months helped them recover faster. Kids who took zinc had shorter coughs (1 day compared to 6 days), less runny noses (2 days compared to 5.5 days), and fewer days with multiple cold symptoms.⁷
For teenagers, zinc helps balance hormones, supports mood, and keeps the immune system strong. A study found that teenage girls with low zinc levels were more likely to feel anxious or depressed.⁸ In summary, during growth spurts and big changes in the body, zinc is a must-have nutrient.¹
C is for Cold, Flu and Immune Health
Zinc supports your immune cells to respond quickly and effectively to invaders. Without enough zinc, your immune system can become more susceptible to infection.⁹ Highlighting these benefits, a review found that when taken within 24-48 hours of symptoms starting, zinc can reduce the duration and severity of colds. When taken long-term (over 5+ months), zinc also lowered the frequency of colds and the need for antibiotics.¹⁰
M is for Mood and Brain Health
Zinc is essential for our mental well-being and brain function. When zinc levels are low, people may face mood challenges or have trouble focusing. Zinc helps boost something called BDNF, a protein that supports brain growth and healing. People with low mood often have low BDNF, and zinc helps bring it back up to support brain health.¹¹ Zinc also helps calm the brain by balancing glutamate, a brain chemical linked to mood and memory. Zinc may even help repair tissue damage from things like strokes, seizures, or head injuries.¹²

P is for Pregnancy and Making Babies
Zinc requirements increase during pregnancy and breastfeeding due to its role in genetic development and brain growth. It can also support healthy blood glucose levels and reduce the risk of high blood pressure during pregnancy.¹³⁻¹⁶
S is for Skin Health and Healing
Zinc acts like your skin’s maintenance crew. It helps repair tissue, reduce inflammation, and support collagen production. Low zinc levels can impact the rate of skin healing.¹⁷
Studies show zinc supports skin and wound healing with:
• Improved acne outcomes and reduced rosacea flare-ups.¹⁸
• Enhanced healing after surgery.¹⁹
Supplementing zinc can speed up skin recovery and reduce scarring, especially after injury or trauma.¹⁷
T is for Testosterone and Men's Health
Last but not least, zinc is an important mineral that helps support Men's health. In males, it helps support important hormones like testosterone needed for energy and mood balance. Studies show that low zinc levels can lead to lower testosterone, but taking zinc can help increase it.²⁰
Zinc also affects sperm health. One study found that men with low sperm motility or low sperm count had less zinc in their semen compared to fertile men.²¹
Z is for Zinc: A Small Mineral That Makes a Big Difference
Science is showing just how important good nutrition is for overall health, and zinc plays a key role. From immune support and mood to skin repair, growth, and fertility, this small but mighty mineral does a lot. To get enough zinc, regular intake through food or supplements is essential.
As a supplement, you can take it on its own, alongside other immune nutrients found in Meta Zinc with Vitamin C in delicious Orange and Raspberry flavours) to support all ages. While FemmeX, a magnesium formulation designed for women, or Male Essentials, a multivitamin and mineral complex both contain zinc along with other nutrients, designed provide whole-body support.
