Lychee is a sweet tropical fruit packed with vitamin C, polyphenols, and flavonoids. You can eat it fresh, drink it as juice, or take a concentrated extract.
Many people use lychee for general antioxidant support. Most enjoy it as a food, but standardized extracts offer a stronger dose for those who want one.
Severe cautions apply. Unripe lychee contains hypoglycin A, a toxin that can trigger dangerous low blood sugar and acute toxic brain reactions, particularly in underfed children. Only eat fully ripe lychee. Some extracts may also alter platelet function. Talk to a doctor before using concentrated supplements if you take blood thinners.
