DOES IT WORK?
Results vary. Carrots are a top source of beta-carotene (provitamin A). Eating carrots genuinely supports vision, skin, and immune health. In supplement blends, the tiny amount of carrot powder included is mostly symbolic. You'd need to eat the equivalent of multiple carrots to get meaningful beta-carotene from a powder.
