What is beta carotene?

Beta carotene is an orange red pigment from the carotenoid family. You’ll find it abundantly in many brightly coloured fruits and vegetables.

It is a provitamin A carotenoid, meaning your body converts it into vitamin A (retinol) as needed. For many people worldwide, beta carotene is an important dietary source of vitamin A.

Your body regulates how much beta carotene it converts based on your vitamin A status. When you have enough vitamin A, this conversion slows.

This makes beta carotene a self regulating source of vitamin A. It differs from preformed vitamin A, which can accumulate in your body when consumed in excess.

Vision, immune function, and mucous membrane health

Vitamin A made from beta carotene plays an essential role in healthy vision. It is needed to produce rhodopsin, a light sensitive pigment in your retina.

Rhodopsin helps you see in low light. Adequate vitamin A also helps maintain healthy vision and supports the health of your cornea.

Vitamin A helps maintain the epithelial tissues lining your eyes and mucous membranes. These tissues line your respiratory, digestive and urinary tracts.

They form important physical barriers that help protect your body from harmful pathogens. Vitamin A therefore supports immune function by helping maintain these protective barriers.

Beta carotene also provides antioxidant support. Its role in immune health therefore comes from both vitamin A production and its own antioxidant activity.

Skin health and antioxidant protection

Beta carotene also acts as an antioxidant, beyond its role as a source of vitamin A. It can help neutralise singlet oxygen, a highly reactive form of oxygen.

UV exposure can increase oxidative stress in your skin. Beta carotene’s antioxidant activity may therefore help protect your skin from oxidative damage.

Carotenoids can also accumulate in your skin and contribute to a warm, golden complexion. Higher dietary intakes have been associated with this subtle change in skin tone.

Beta carotene may also help protect collagen and elastin from oxidative damage linked to sun exposure and ageing. This makes it an interesting nutrient for supporting healthy skin over time.

Getting beta carotene from diet and supplements

A varied diet rich in colourful fruit and vegetables provides plenty of beta carotene. Eating these foods with some dietary fat can also improve absorption.

Beta carotene is fat soluble, so your body absorbs it more effectively alongside fat. Light cooking, such as steaming or roasting, can also improve its availability. Cooking softens plant cell walls, making beta carotene easier for your body to absorb.

If you take a supplement, consider a natural mixed carotenoid formula. These formulas provide beta carotene alongside alpha carotene, lycopene and lutein. This combination more closely reflects the range of carotenoids found naturally in a varied diet.
