How Vitamin C supports general health
For general health support, Vitamin C is a supporting ingredient backed by research. 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.
How much vitamin c do you need
Research points to 250–2000 mg as the effective range for vitamin c. Common supplement range; UL is 2000 mg/day. Lower doses may provide some benefit, but most studies showing clear results used this range.
Which form absorbs best
Avoid ascorbic acid — standard form — absorption drops above 1,000mg. Avoid ester-c — marketing claims, unclear benefit over standard forms. Avoid ascorbyl palmitate — fat-soluble form, limited bioavailability data. The most bioavailable options are calcium ascorbate or liposomal vitamin c.
