In fact, vitamins A, C, and E all play similar roles in the body, and it’s difficult to tell apart amongst their effects.

- The American Dietetic Association (ADA) recommends that nutrient needs come from a wide range of meals taken from different dietary sources quite than from self-prescribed vitamin dietary supplements.
- Pernicious anemia is caused by a lack of a glycoprotein known as intrinsic factor that is required for absorption of vitamin B12.
Types And Examples Of Foods
It additionally performs a role within the physique’s absorption, use, and storage of iron. Vitamin C is an antioxidant and is therefore believed to protect cells a lot as vitamin E does. An rising physique of proof suggests that a tremendously elevated quantity of vitamin C within the food regimen lessens the danger of coronary heart disease and cancer. Each of the B vitamins acts by combining with one other molecule to kind an organic compound often known as a coenzyme.
Some researchers have made extravagant claims about the advantages of enormous doses of specific vitamins as either preventatives or cures for illnesses from acne to cancer. As new discoveries are made and old claims are both debunked or bolstered usually, it is safest to say that more is known concerning the consequences of lack of vitamins than what explicit vitamins may do.
