Vitamin A functions

Vitamin A aids:

  • Normal growth and development of tissues

  • Immunity

  • Vision

Vitamin A dosage

The Nutrient Reference Value (NRV) is 800mcg a day. In Heights Smart Supplement there is 150mcg (equal to 2 boiled eggs or 2 cups of baked beans) this is 19% of the recommended amount.

Vitamin A and the brain

Beta carotene may improve cognitive function; one 18-year study of more than 4,000 men linked long-term beta carotene supplementation to the slowing of cognitive decline.

Vitamin A benefits

Vitamin A has the following benefits:

  • It may improve cognitive function

  • It helps to maintain a healthy immune system

  • Supports vision in dim light (carrots really do help you to see in the dark!)

  • It keeps skin and mucous membranes like inside the nose healthy

Plays well with

All immune-boosting nutrients as well as vitamin B2 for eye health (also in Heights!)

Clever stuff

Our bodies make vitamin A by converting its precursor, beta carotene into the active form. Beta carotene is the compound that is responsible for the orange colour of carrots.


Evidence

Here’s a handful of relevant scientific studies on vitamin A.

  • Grodstein, F., Kang, J. H., & Gaziano, J. M. (2004). O3-01-08 A large randomized trial of beta-carotene supplements and cognitive function. Neurobiology of Aging, (25), S54.
