Vitamin B8 - Biotin - Strengthens Immunity

Vitamin B8 or biotin is one of the most active biological substances known. An extremely small amount of this vitamin has a marked effect on the growth of yeast and certain bacteria. It forms part of several enzyme systems. Biotin is freely soluble in hot water, but sparingly in cold water. It is insoluble in fat solvents and sparingly soluble in alcohol. Water, sulpha drugs, oestrogen, food processing techniques, alcohol, and in particular, large quantities of egg white can destroy this vitamin.

Recommended Daily Allowance - Vitamin B8

Men 100-200 mcg
Women 100-200 mcg
Children 50-200 mcg
Infants 35 mcg

It may cause eczema, dandruff, hair loss and seborrhoea. Other common problems which may occur are skin disorders, heart abnormalities, lung infections, anaemia, extreme fatigue, confusion, mental depression, and drowsiness.
