Camu camu is a small fruit from the Amazon rainforest. Its flesh supplies a concentrated dose of vitamin C, along with antioxidant flavonoids and ellagic acid.
The vitamin C in camu camu helps the body produce collagen and defend against oxidative stress. People blend the powder into smoothies, juices, or water, or take it in capsules.
Large doses of vitamin C may cause digestive discomfort. If you have a history of kidney stones, talk to a doctor before taking camu camu in high amounts.
