Black carrot (Daucus carota ssp. Sativus) is a dark purple to black variety. Its color comes from anthocyanins, not the high beta-carotene of orange carrots. The antioxidants in black carrot may help the body defend against oxidative stress.
You can find black carrot as whole food (raw or cooked), juice, powdered extract, or concentrated supplement. The active compounds are water-soluble, so timing meals is not crucial, though many take it with food for convenience. Reliable human studies are few, but traditional use and early research point to possible heart and immune support.
Food amounts rarely cause issues. However, safety data for high-dose, concentrated extracts over long periods is missing. If you have a medical condition or take medication, talk to a professional before using concentrated forms.
