The Claim

A single 500 mg oral dose of liposomal vitamin C increases peak plasma concentration by 27% and total plasma exposure (AUC0–24) by 21% compared to an equivalent dose of standard vitamin C in healthy adults aged 18–45, demonstrating enhanced bioavailability due to improved gastrointestinal absorption and protection from degradation.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

When healthy adults aged 18–45 take a 500 mg oral dose of liposomal vitamin C, their peak plasma concentration rises by 27% and their total plasma exposure over 24 hours increases by 21% compared to taking the same dose of standard vitamin C.

See the scientific wording

Why this might work

Vitamin C wrapped in a fat-based bubble survives stomach acid and digestive enzymes, allowing it to reach the intestine intact. There, the vitamin is absorbed through special transporters in the gut wall that pull it into the bloodstream more efficiently than regular vitamin C, which breaks down easily and gets absorbed poorly.

  1. Study: Liposomal delivery enhances absorption of vitamin C into plasma and leukocytes: a double-blind, placebo-controlled, randomized trial

    This study found that vitamin C wrapped in tiny fat bubbles gets into the blood better than regular vitamin C pills, meaning more of it survives digestion and reaches your body.
