B7 (also known as biotin) sources include Swiss chard, eggs (mainly the yolk), liver, some vegetables and supplements. Most daily multivitamin and mineral formulas (MVM) contain all the biotin necessary (and probably a little more) for normal people. Although full biotin deficiencies are rare, marginal deficiencies have been shown in certain populations such as during pregnancy, athletes, dieters, elderly, alcoholics, and burn patients, which can lead to decreased energy production and other biotin related functions. For this reason we always recommend a daily MVM to all populations containing between 100-300 mg of biotin (B7). Active people maintaining low body fat may do better at the higher part of this range. If you are diagnosed as biotin deficient, your doctor will prescribe the proper amount as a medicine.
Vitamin B7 often comes as part of a multivitamin tablet or a prenatal vitamin. But it is available in tablets on its own when higher doses are needed. Tablets should be taken with at least eight ounces of water. If your stomach is sensitive to vitamins, you can take it with food or increased amounts of water. Take the tablet as many times daily as the label or your doctor instructs.
