Truly NaturalVitamin C provides naturally-occurring and highly-bioavailable non-toxic vitamin C from a whole-food water extract of acerola cherry. Native to South and Central America, acerola is one of the highest natural sources of vitamin C on the planet. Food sources of vitamin C are the most bioavailable and compatible to the living matrix of the human body and far superior to isolated vitamin C. Vitamin C never occurs as an isolate in Nature. It occurs as part of an entire vitamin C complex, which includes other important cofactors that assist the body with proper absorption. Trust in Nature's wisdom!
