Whole World Botanicals Royal Camu Dark Powder comes in a screw-top glass jar containing 74 grams or 2.6 ounces of pure Camu Camu berries. This naturally containing Vitamin C super food also contains the bioflavonoids to help promote the benefits found with Vitamin C. Royal camu is unique, because the Camu Camu berries are harvested and frozen almost immediately on a freezer boat before they are even brought back for processing. This preserves the natural Vitamin C content so well, ascorbic acid is not added in after processing to artificially boost the Vitamin C's content like most every other company that sources Camu Camu berry for supplemental purposes. And since natural Vitamin C is more than 10 times more bioavailable than artifical ascorbic acid, the difference in Camu Camu from Whole World Botanicals is noticeable right away. With natural Vitamin C, Royal Camu Camu contains proanthocyanidins, flavonoids( including Gallic Acid and Ellagic Acid), thiamin, riboflavin, and niacin along with the essential amino acids.
