Vitamin C

About Vitamin C

Potent antioxidant and cofactor for collagen synthesis, immune function, and iron absorption. Liposomal vitamin C provides significantly higher bioavailability than standard ascorbic acid by encapsulating the molecule in phospholipid spheres for enhanced cellular uptake. Buffered forms (mineral ascorbates like calcium or magnesium ascorbate) reduce gastric irritation for sensitive stomachs. Smokers need an additional 35 mg/day.
