Verified Merchandise Itemizing
for greater than 100 dietary supplements throughout quite a few retailers.
“There are all kinds of dietary supplements on the market,” Lavigne says. “One of many issues you possibly can search for is the U.S. Pharmacopeia label, which suggests it has been examined for high quality.”
