AcerolaÂ Cherry, also known as Acerola Berry, Barbados Cherry or West Indian Cherry,is one of nature's highest sources of vitamin C. The fruit can yield up to 4,000 mg of vitamin C per 100 grams of fresh weight. Often used as a Vitamin C additive.Â Acerola cherries provide more vitamin C than all other food sources, according to the U.S. Department of Agriculture.Â Fresh acerola juice contains 13 times more vitamin C than an equal portion of orange juice. Youâ€™ll get 1,644 milligrams of vitamin C from 1 cup of fresh fruit and 3,872 milligrams from 1 cup of juice. These values far exceed the recommended daily allowance of 75 milligrams for women and 90 milligrams for men. Itâ€™s rare to experience side effects from getting too much vitamin C, although common problems such as diarrhea, nausea and cramps may arise, according to the Office of Dietary Supplements. Taking large amounts in supplements may increase your risk of developing kidney stones. To avoid potential health problems, adults should not consume more than 2,000 milligrams daily, the Office of Dietary supplements cautions.
