Our potent formula contains the highest natural source of vitamin C in the world, a.k.a. Kakadu Plum. This organic vitamin C was thoughtfully crafted to create a blend of the most powerful antioxidants that help support your immune system, cognition, collagen synthesis and heart health. ADDED ZINC & COPPER Copper contributes to skin and hair by helping you make melanin, which helps protect your skin from the sun's harmful rays. Zinc helps cells in your body communicate with each other, aiding in nerve communication and hormone regulation. WHY LIPOSOMAL? Liposomal vitamin C is more absorbable. Liposomes are microscopic droplets surrounded by a lipid bilayer, the same kind of barrier that mimic our cell membranes.
