Vitamin A

Vitamin A (also called retinol) is a yellow, fat-soluble vitamin found in egg yolks and the livers of many animals. Vitamin A and beta-carotene are closely related nutrients. The difference is that all vitamin A is preformed—and comes from animal sources (meat, eggs, milk, cheese), while beta carotene is a precursor of vitamin A (also called Provitamin A), which means that it comes in a form that the body converts to retinol by normal metabolic processes. Beta carotene comes from fruits and vegetables such as sweet potatoes, carrots, kale, spinach, turnip greens, winter squash, collard greens, cilantro, and fresh thyme. Beta-Cryptoxanthin is a source of vitamin A, but about 2 times less strong than beta-carotene.

Special Precautions of Vitamin A

High doses of vitamin A can raise concerns about toxicity, because this fat-soluble vitamin accumulates in the body and tax the liver. For this reason, some practitioners prefer beta carotene, which does not accumulate in the body and is associated with fewer risks. However, those interested in using either vitamin A or beta carotene for cancer treatment or prevention should consult with a health practitioner knowledgeable about these nutritional therapies for guidance with the best forms and dosages, as well as possible combination therapies to enhance effectiveness.
