★ HIGH ABSORPTION VITAMIN C ★ High doses of regular ascorbic acid Vitamin C is poorly absorbed by the body, and the excess is flushed out as waste. Liposome technology greatly improves the bioavailability and stability of this water-soluble vitamin by wrapping it inside a lipid layer.

More importantly, this improved bioavailability allows you to take advantage of everything this essential vitamin offers!

★ DRY FORM LIPOSOMES ★ We use special liposomes formulated from coconut oil powder (standardized to 50% medium chain triglycerides or MCT) and sunflower seed lecithin. The coconut oil + sunflower lecithin combo protects the vitamin from oxidation and shields your digestive tract from Vitamin C’s acidity!
★ SUITABLE FOR VEGETARIANS & VEGANS ★ Our Liposomal Vitamin C capsules use no other ingredients apart from Vitamin C (Ascorbic Acid, Ascorbyl Palmitate), our plant-based phospholipid complex and veggie capsules.
