Acerola berry is indigenous to Central America and contains a diverse mix of antioxidants including carotenoids and bioflavonoids that help to boost the immune system, neutralize the effects of free radicals and cleanse toxins. Acerola berry is extremely rich in vitamin C (one berry is equal to one orange in vitamin C). In fact, JOJ’s 2 oz. shot contains as much vitamin C as 8 to 10 oranges. The shot also contains vitamins A, B1, B2 and B3.
