Yes, that's what RichVank said back in 2010. I've supplemented with various protein powders, undenatured whey, amino acids, etc.. Some I can tolerate, others not (like BCAAs for some reason, which should be helpful). So once I can get back to a decent doc, I'm going to see if I can get more tests done to see if heavy metals are inhibiting the krebs cycle (mine drops off at a-ketoglutarate), or if I'm missing some mineral cofactors.
Also it's possible some infection could be interfering as well. Anyway, thanks for your reply -- that's great that you're finding some benefit from them
@Murph. Do you mind my asking what brand/form?
