The food in prison is toxic and dangerous, just like the supplements..
So i guess they both work..
and you're basing this on what, you can just google or go on youtube and see all the evidence, most of the supplements are bloated with shyt you don't even know what it is
supplements in the medical term are used to replace food in the case of an illness or some kind of infliction where the person can't ingest food regularly
there is nothing those supplements do that real nutrition won't do ten times better, that's why its a scam, and also you are damaging your body
in prison they're not intaking enough toxins to damage the body
