My friend found some site promoting this R-ALA saying its the purest form blah blah blah, personally I don't even think ALA is needed unless your dieting and are on a low nutrient diet but what the site was promoting caught my attention so I'm throwing it out to you guys. Is there a difference between R-ALA and L-ALA and ALA or is it all bullsh*t or so insignificant that doesn't even matter.
