The B vitamins are key to the bodys vital metabolism, while contributing significantly to the reduction of stress and fatigue. They help maintain the health of mainly the nervous and digestive systems and promote the health of the skin, hair and nails. Although they can be taken individually, the way they act in the body is commonly linked (e.g. B12 is a prerequisite for the action of folic acid in red blood cells). For this reason, it is considered more complete to take the entire complex to cover daily needs. HealthAids B-Complex provides a stable dose of all B vitamins, well balanced, in an immediate-release capsule that is easy to swallow. Useful after antibiotic treatment or in people in recovery, as well as alcoholics or smokers. Excellent supplement for nerve pain (e.g. back pain)
