VITAMIN C (ascorbic acid) is a water-soluble vitamin. It plays a role in maintaining healthy gums, skin and connective tissue. It furthermore assists the absorption of iron from food, and functions as a tissue anti-oxidant, thereby keeping cells healthy. Vitamin C also contributes to maintaining the normal function of the immune system during & after intense physical stress and potentially reduces tiredness & fatigue. Ascorbyl palmitate has also been added as an ester formed from ascorbic acid and palmitic acid creating a fat-soluble form of vitamin C. Citrus Bioflavonoid and Rutin have been added to improve absorption. IMMUNO BOOST provides a complete blend of botanical ingredients. High levels of anti-oxidants and herbs, which traditionally have been used to support one’s immune system, have been included.
