Klaire Labs Multi-Element Buffered C Powder with Quercetin & L-Glutathione - 260g (65 Servings)

Key Benefits of This Multi-Element Buffered C Formula

This powder isn't just about vitamin C. It also contains the potent bioflavonoid quercetin and reduced L-glutathione, both of which work alongside vitamin C in the body's natural defences.* The mineral blend helps maintain electrolyte balance and supports bone health. With added antioxidants, this formula provides comprehensive nutritional support for everyday wellness.

Each serving delivers a robust dose of vitamin C, backed by minerals that many vitamin C products lack. Quercetin, a bioflavonoid found in fruits and vegetables, may contribute to a healthy immune response.* L-glutathione, often referred to as the master antioxidant, helps recycle other antioxidants in the body, including vitamin C.*
