About Pure Encapsulations - Buffered Ascorbic Acid 90 capsules

Pure Encapsulations Buffered Ascorbic Acid delivers vitamin C in a mineral-buffered form, combining ascorbic acid with calcium, magnesium, and potassium ascorbates, to support immune function, antioxidant defense, and connective tissue integrity. The buffered format reduces the acidity of standard ascorbic acid, making it a consideration for those with sensitive digestive systems who still want meaningful vitamin C intake.

Why It's Worth Considering: Pure Encapsulations formulates to practitioner-grade standards with minimal excipients and no unnecessary fillers, and the mineral ascorbate blend offers a gentler gastric profile compared to straight ascorbic acid.
