Overview
NOW Foods Vitamin C Crystals is a pure ascorbic acid powder sold in an 8 ounce container, meant to be measured out rather than taken as a fixed capsule dose.
Powder form gives control over dosage that capsules don't, letting buyers mix a measured amount into water or food, which suits people who want flexible or higher volume vitamin C use. It is unflavored, vegan and vegetarian, and labeled allergen free. Unlike the whole food vitamin C capsule elsewhere in this catalog, this is synthetic ascorbic acid, a more common and typically lower cost vitamin C source.

Who it's for
Suits buyers who want a flexible dose, unflavored vitamin C powder to mix into drinks or food, including vegan and vegetarian shoppers. Not the right pick for anyone who wants pre measured capsules or a flavored product.
Strengths and trade-offs
Drawn from this product's published specifications.
- Flexible dosing as a mix in powder
- Vegan and vegetarian
- Unflavored, allergen free labeling
- Requires measuring your own dose, no capsules
- Synthetic ascorbic acid, not a whole food source
Performance notes
As a powder, its practical use depends on how much you measure per serving, so the 8 ounce container's actual duration varies with how it's dosed rather than a fixed serving count on the label.
