According to the U.S. Department of Agriculture, Acerola Juice is the richest source of NATURAL VITAMIN C .It is a cherry, officially called berry, which grows semi-wild and is native to tropical and subtropical America, especially in the Caribbean area. It is a small tree or bush 4 to 10 feet in height. The fruit is a pseudo-cherry but is not related to our regular cherry species. It requires about 12 to 25 "cherries" to supply 2000 mgs. Of Vitamin C (commonly known as Ascorbic Acid). But the Acerola has much more than just Vitamin C. For example, 100 grams of the Acerola juice contains: 1692.8 mgs. of Vitamin C (1200 to 4000 average about 1700) 30.0 mgs. of Thiamine 50.0 mgs. of Riboflavin 290.0 mgs. of Niacin.
