UHA Gummy Supplement Vitamin C is a lemon flavored Japanese gummy supplement made for easy daily use when you want vitamins in a format that feels simple and familiar. The standard serving of two gummies provides 500 mg of vitamin C, vitamin B2, and 200 mg of collagen, and this 100 day pack comes as ten smaller 10 day portions that are easy to carry, share, or keep at work. It is best for shoppers who prefer a no water supplement, want a steady everyday vitamin C habit, and like a chewy texture instead of tablets or capsules.
