There are a number of different Saw Palmetto products on the market. There are gel caps, capsules, tablets, etc. There are a number of Saw Palmetto products designed specifically for the prostate.
There are also Saw Palmetto shampoos that claim to stop hair loss and promote hair regrowth. There are even “breast enlargement pills” that contain Saw Palmetto.
Keep in mind that many of these products are not regulated by the FDA and most are not scientifically tested to see if they live up to their claims. That is not to say that none of these products are effective or useful but that you should be wary of extravagant claims made by some merchants.
