Vitamin A (Also known as: Beta Carotene, Retinol)

Why you need it?


Vitamin A helps cells reproduce normally – a process called differentiation. Cells that have not properly differentiated are more likely to undergo precancerous. Vitamin A, by maintaining healthy cell membranes, helps prevent infections. It also stimulates immunity and is needed for formation of bone, protein and growth hormone. Beta-carotene, a substance from plants that the body can convert into Vitamin A, also acts as an antioxidant. Other members of the carotene family include cryptoxanthin, alphacarotene, zeaxanthin, Lutein, and Lycopene, but most do not convert to significant amounts of Vitamin A.

GRAS – Generally recognized as safe. No adverse reactions, side effects or overdose symptoms expected when taken within the recommended amounts.

No adverse effects have been reported as a result of taking Beta-Carotene supplements during pregnancy or lactation. Individuals taking Beta-Carotene for long periods of time should also supplement with Vitamin E, as Beta-Carotene may reduce Vitamin E levels.

Women who are or could become pregnant should take less than 10,000 IU (3,000µg) per day of Vitamin A to avoid the risk of birth defects. For other adults, intake above 25,000 IU (7,500µg) per day can- in rare cases- cause headaches, dry skin, hair loss, fatigue, bone problems, and liver damage. Beta-Carotene, however, does not cause cause any side effects, aside from excessive intake (more than 100,000 IU, or 60mg per day) sometimes giving the skin a yellow-orange hue.

Retinol contraindicated with compromised liver, hepatitis or any liver disease.

Cyclophosphamide (Cytoxan): requires hepatic oxidation for activation; antioxidants interfere with this process.
