The Claim

Liposomal vitamin C reaches peak plasma concentration at 4 hours after ingestion in healthy adults, and nonliposomal vitamin C has a shorter time to peak plasma concentration.

Description
1 study reviewed
In plain English

When healthy adults take liposomal vitamin C, the highest level in the blood occurs 4 hours after ingestion. Nonliposomal vitamin C reaches peak blood levels faster.

See the scientific wording

Liposomal vitamin C reaches peak plasma concentration at 4 hours after ingestion in healthy adults, which may indicate a slower absorption profile compared to nonliposomal vitamin C, though the latter’s Tmax is not reported.

Why this might work

Vitamin C enclosed in tiny fat bubbles survives stomach acid and intestinal enzymes, enters intestinal cells intact, and releases vitamin C slowly inside the cells, which then enters the bloodstream over several hours.

  1. Study: A clinical evaluation of liposomal (Lipomac™) versus nonliposomal vitamin C: A randomized, open-label, cross-over trial in healthy subjects

    This study found that liposomal vitamin C takes about 4 hours to reach its highest level in the blood, which suggests it’s absorbed more slowly than regular vitamin C — even though they didn’t measure how fast the regular kind gets absorbed. The liposomal version still ended up with much more vitamin C in the blood overall.
