Overview
A buffered vitamin C tablet from Metagenics, sold in a 90 count bottle and formulated non-GMO and gluten free. The buffering is what the label ties to stomach comfort, alongside standard immune and collagen formation support.
Buffering neutralizes some of the acidity found in plain ascorbic acid, which is the mechanism behind the stomach comfort claim rather than a separate added ingredient. This puts it in the practitioner-brand corner of the vitamin C market rather than a mass-market gummy or chewable line.

Who it's for
Fits people who want a higher-potency vitamin C tablet but find plain ascorbic acid hard on the stomach. Not for anyone wanting a chewable, gummy or liquid vitamin C format.

Performance notes
