Theres a massive big post on b2 on pr. Many used it in high doses, low doses. They were adding co-factors etc. A few felt better but i dont recall any recoveries.
That B2 I love you thread is huge. And many people discovered it's not that simple to just take B2 in a vaccuum. All the other B2 have to be balanced.
Many people found that there is this huge trickle down effect. Too much B2 depletes something else etc and can cause tons of other problems. I don't remember specifics but Mary had problems balancing them.
Its irresponsible to post a bunch of studies then say "oh I have the cure" just take biotin without looking at the big picture of not just antioxidants but the disease In its entirety.
