Overview
NOW Foods' Vitamin C-500 uses calcium ascorbate, a buffered form of vitamin C, in a 250-count vegan capsule bottle. Aimed at anyone who wants a large-supply vitamin C option that's gentler on the stomach than plain ascorbic acid.
Calcium ascorbate is a buffered, non-acidic form of vitamin C, which matters for anyone who finds standard ascorbic acid hard on the stomach; it also adds a small amount of calcium alongside the vitamin C. At 250 capsules, this is a large bottle built for daily long-term use rather than a short course. There's no seller description or review history on this listing, so the buffered-form detail and count are what can be confirmed from the label.
- Vitamin C as calcium ascorbate
- 250 veg capsules per bottle
- Vegan, dairy/egg/nut/soy free
- Marketed for antioxidant and immune support
Who it's for
Fits someone who wants a large-supply vitamin C capsule in a gentler buffered form, ideally already comfortable swallowing capsules daily. Less suited to someone who wants a chewable, gummy, or unbuffered ascorbic acid product.
