Keep reading to find out more about the importance of getting enough zinc, the benefits of taking zinc supplements and how much your body needs to thrive.
Potential benefits of zinc supplements
Making sure you have enough zinc can help to support your overall health.3,5 However, zinc isn’t stored in the body.3 This means we need to make sure we’re getting enough of it every day, either through our diet or dietary supplements.3
There are several potential health benefits of getting enough zinc, including:3,5-7
- immune support – zinc is highly involved in the normal function of the immune system
- antioxidant properties – zinc contributes to the protection of cells from oxidative
- stress, which can lead to cell and tissue damage
- supports normal cognitive function
Should I take zinc supplements?
Most people can get enough zinc from eating a healthy, balanced diet.4 As a result, zinc deficiency is relatively uncommon, though it’s more frequent in certain groups of people, including:2,6
- those with gastrointestinal disorders – people with inflammatory bowel disease, coeliac disease or those who’ve had bariatric surgery are more likely to have a zinc deficiency
- vegetarians and vegans – although vegetarian and vegan foods contain zinc, the bioavailability of zinc from these foods is low
- pregnant women – growing foetuses need zinc to develop, meaning that pregnant women need an increased amount of zinc to accommodate the baby’s needs
- exclusively breastfed older infants – if a baby is being exclusively breastfed past the ninth month, it’s recommended they also consume age-appropriate foods or formula containing zinc
Consequently, these groups of people are more likely to be recommended a zinc supplement.2,6
Always check with your healthcare professional. Supplements are not intended to cure, treat or prevent any health conditions.
How much zinc to supplement?
Overall, people of different ages need slightly different amounts of zinc every day. Below are the recommended dietary allowances for zinc for adults:4
- for men aged 19-64 years: 9.5 mg a day
- for women aged 19-64 years: 7 mg a day
Overall, however, you shouldn’t take more than 25mg of zinc supplements a day.4 Additionally, you shouldn’t take iron supplements providing above 25mg alongside zinc, as this can reduce zinc absorption.2
