Functions of zinc in the body

An essential nutrient that the body can’t produce or store - Creation of DNA - Immunity - Growth and development

Zinc dosage

The Nutrient Reference Value (NRV) is 7.5mg per day. In every dose of the Heights Smart Supplement there is 5mg (equal to a whole lobster or 2 oz of pumpkin seeds). We don't include a 100% NRV in Heights as it is easy to get zinc from your food naturally. As a trace mineral, you don't want to get too much either (it is all about finding the right balance).

Zinc research

Studies have shown that symptoms of depression and low mood can be improved by zinc supplementation for some people, and it has seen positive results when trialled alongside antidepressants to improve efficacy.

Zinc and brain function

Zinc is known to be helpful for spatial memory - e.g. your recollection of the environment around you. It also helps with normal brain function, and a deficiency in zinc may result in issues with attention span, activity, neuropsychological behaviour and motor development.

Zinc benefits

Zinc has the following benefits

  • Vital for making new cells and enzymes

  • Important for metabolising macronutrients (carbs, fat and protein)

  • Wound healing and collagen formation and maintenance

Zinc absorption

Lots of things in our diet make it harder to absorb zinc, so taking it in supplement form can ensure your levels are topped up.

Clever stuff: Lack of zinc during pregnancy

Some child mental health issues can be traced back to low levels of zinc during pregnancy, so getting enough zinc might be able to help prevent mental health disorders in kids.
