Overview

Formulated with calcium ascorbate rather than plain ascorbic acid, this capsule is built to be gentler on digestion while still delivering 500 mg of vitamin C per serving. It ships as an unflavored, vegan capsule in a large 250-count bottle, making it a straightforward swallow-and-go option for regular use.

The label pairs stated antioxidant and immune support claims with a dairy-, egg-, nut-, and soy-free ingredient profile, which broadens who it might work for compared to formulas built on animal-derived ingredients.

Frequently asked questions

What is calcium ascorbate?

It's a buffered form of vitamin C bound to calcium, which the maker markets as easier on digestion than standard ascorbic acid. It also means each capsule contributes a small amount of calcium.

Is this vegan?

Yes, the capsules are labeled vegan and free of dairy, egg, nut, and soy.

How long does a 250-count bottle last?

That depends on how many capsules you take per serving, but at one per day it would last roughly eight months. Check the label's serving size for the manufacturer's guidance.
