B vitamins are essential co-factors in a wide range of metabolic reactions. As most B vitamins are water-soluble, we need an adequate daily supply to support the proper metabolism of proteins, fats, and carbohydrates, and to support normal growth and development. B vitamins are particularly involved in the health of skin, hair, and nails, nerves, and in digestion, playing a key role in gene expression and tissue generation. , , Because they work synergistically, it's best to take B vitamins as a complex. This also helps to prevent accidentally masking any B vitamin deficiencies, such as inadequate vitamin B12, which can cause permanent nerve damage and pernicious anaemia. The body's demands for B vitamins increase when life is hectic and stressful and when a person is more physically active. , , B100 Complex from Webber Naturals is our highest potency formula and provides an optimal ratio of these essential nutrients for daily energy support.
