Our take on the formula
Protoflow is closer to a general men's vitality blend than a classic prostate formula. The largest amounts go to hawthorn, epimedium, damiana and muira puama. Saw palmetto, the ingredient most associated with prostate support, is included but at a modest dose. If saw palmetto is the main thing you are looking for, compare the amount per serving before you choose a product.

Who should talk to a doctor first
Urinary symptoms such as getting up at night, a weak stream or urgency can have several causes, including some that need medical care. See a doctor before relying on any supplement. This is especially important if you:
- take blood thinners, blood pressure medication or any prescription drug (ginkgo and niacin can interact with some medications)
- have a diagnosed heart, liver or prostate condition
- have a soy allergy or avoid animal-derived gelatin
