Saw palmetto berry powder comes from ground whole berries. It delivers the full spectrum of compounds in the fruit, though it is less concentrated than a standardized extract.
Men often take it to support urinary function. People also take it for hair health, but the evidence here is thin. Effects may not appear for several weeks.
Mix the powder into a drink or smoothie. Taking it with a meal helps absorption. Pregnant or breastfeeding people should avoid it. Some sources note a possible mild blood-thinning action, though proof is weak. Speak with a healthcare professional before use if you take medication or have a health condition.
