B-Vitamins for Healthy Nervous and Immune Systems and Skin!
B-vitamins aid e.g. the nervous system, memory, the ability to concentrate, mood, the skin, mucous membranes, metabolism, and the immune system. B-vitamins are particularly needed if you suffer from e.g. intestinal diseases or stress or happen to be under a lot of pressure.
Vitamin B12 is particularly recommended for those on a vegan diet. Vitamin B9, i.e. folate, is needed for normal growth and development. Adequate folate intake is particularly important during pregnancy. Folic acid is a synthetic form of folate. Vitamin B7, or biotin, promotes the maintenance of healthy hair, skin and mucous membranes.
Remember that because B-vitamins are water soluble, you should take them on a daily basis.
