Frequently asked questions (FAQs) about zinc supplements

What is zinc?

Zinc is an essential mineral that our bodies need to keep healthy and fit (2,3,4,5). It helps our immune systems in staving off harmful bacteria and viruses. Our bodies also need zinc for hair maintenance, cell division, and cell growth. It plays a role in breaking down carbohydrates, as well as helping our sense of taste and smell. Our bodies need zinc during pregnancy, infancy, and other key phases of our physical and mental development. Studies have shown the importance of zinc for hair regrowth as the mineral's crucial role in DNA and RNA production (2). Zinc is also involved in important processes that affect hair follicles, keratinocytes, skin and melanocyte health and function. There’s no doubt that zinc can provide an assortment of health benefits!

What is the connection between zinc and hair?

Zinc is responsible for hair tissue growth, repair and maintenance. Our hair and skin are made of connective tissue which is constantly in a cycle of renewal as old cells are shed and new ones are grown to replace them. Zinc is especially important in building this new connective tissue, which is especially important in improving restorative cell functions in older adults.

How does zinc deficiency impact hair?

Studies (3) have shown that a deficiency in zinc may lead to brittle hair and thinning of hair as its growth can be affected. Disruption in hair growth can cause weakened shafts, increased hair breakage and slow hair growth and development. In fact, poor hair health is a common symptom of zinc deficiency. The rule of thumb for great hair is to ensure that you consume enough zinc to reduce the risk of hair loss.

How much zinc do I need?

According to the Australian Government Health Guidelines, the number of zinc supplements to consume depends on a host of factors that stretch across gender and age groups. Adult men aged 19 years old and above are recommended to consume 14 mg/day, while women above the age of 19 years old require about 8 mg/day (2). For the most relevant zinc requirements, refer to the Australian guidelines (healthdirect.gov.au) and always consult with a health professional before supplementing.

Why do I need zinc supplements?

While it is totally possible to obtain the daily recommended intake of zinc through an ordinary diet, some of us might find it difficult to achieve our daily quota. This can be due to certain nutritional restrictions like a vegan or vegetarian diet, which are commonly low in animal-based sources of zinc. For this reason, vitamin and mineral supplementation may be required to ensure you’re getting the amount of zinc needed (4).
