NOW Foods Calcium Ascorbate, Pure Buffered Powder – 227 grams

Calcium Ascorbate Pure Buffered Powder delivers vitamin C in a non-acidic, buffered form, making it a gentler alternative to standard ascorbic acid powders. Each quarter-teaspoon serving provides 890 mg of vitamin C alongside 100 mg of calcium, both sourced from calcium ascorbate. The 227 g tub contains the powder in unflavoured, pure form with no added fillers or excipients.

Vitamin C is an essential nutrient that contributes to normal collagen formation and plays a role in amino acid metabolism, as well as supporting the body’s ability to utilise nutrients such as folic acid and iron. The buffered calcium ascorbate format is well regarded for its gentle profile on the digestive system compared with acidic vitamin C sources.

This versatile powder can be stirred into water, juice, or a smoothie and suits those who prefer to tailor their vitamin C intake precisely — particularly those following plant-based diets, endurance athletes, or anyone looking for a straightforward, additive-free supplement format.
