I have a long documented history of ranting against supplements. I am very aware. They often contain things they don't say they do and don't contain what they say they do. That most of it's just expensive of urine. That you shouldn't be taking any supplement unless specifically recommended by your doctor because a blood test showed a deficiency and you should know how to make something you take actually bioavailable. The industry is mostly a scam. And I hate going into health food stores. We're more than half the square footage is supplements. Little pharma is trying to steal your money.
