1voteA: Liposomes are tiny phospholipid bilayer spheres — essentially miniature versions of cell membranes — that encapsulate the vitamin C molecule. Because cell membranes are also phospholipid bilayers, liposomal vitamin C is taken up through membrane fusion rather than relying on intestinal transporters that saturate at high doses. Standard oral vitamin C absorption plateaus at approximately 500 mg per dose due to transporter capacity; doses above this produce rapidly diminishing plasma concentration increases. Liposomal delivery bypasses this limitation, producing plasma vitamin C levels significantly higher than equivalent standard supplement doses. This is particularly relevant for high-dose therapeutic or preventive applications.Posted by on Sunday, May 3, 2026

1voteA: The RDA is 75 mg for women and 90 mg for adult men — amounts achievable from diet with adequate fruit and vegetable intake. The Tolerable Upper Intake Level is 2000 mg daily from all sources. Doses between 500 and 1000 mg daily are common for immune and antioxidant support. Smokers need an additional 35 mg daily due to oxidative stress. Very high doses (1000+ mg) from standard supplements are largely excreted given saturation kinetics; liposomal forms are more efficient at these higher doses. For most healthy adults with adequate vegetable and fruit intake, a modest 500 to 1000 mg supplement fills potential dietary gaps without excessive dosing.Posted by on Sunday, May 3, 2026

1voteA: At recommended doses, liposomal vitamin C is well tolerated. The phospholipid encapsulation generally reduces the osmotic diarrhea that standard high-dose vitamin C can cause. High intake (2000+ mg daily) from any form may increase urinary oxalate excretion, raising theoretical kidney stone risk in individuals predisposed to calcium oxalate stones — those with a kidney stone history should use caution and consult their provider. Vitamin C enhances iron absorption, which benefits people with iron deficiency but may be a consideration for individuals with hemochromatosis. People undergoing chemotherapy should consult their oncologist before high-dose C supplementation.Posted by on Sunday, May 3, 2026
