Alacer corp. Is the world leader in vitamin C technology, producing more vitamin C innovations than any other company. While others follow and try to catch up, Alacer continues to pioneer with a full line of vitamin C products that deliver fully reacted mineral ascorbates, day and night. Mineral ascorbates, the true vitamin C, are produced naturally in the livers of 99.9% of all animals, but not in humans. Vitamin C, in the form of mineral ascorbates, has countless advantages over pure ascorbic acid. Mineral ascorbates are neutral (non-acidic) and have no adverse side effects, unlike high levels of ascorbic acid which may cause heartburn, nausea, flatulence, diarrhea, and excess urination, inducing loss of minerals.
