Q&A with Leyla, Part 2: CoQ10 v. PQQ

I'm a 70-year-old woman with hip arthritis. Any recommendations? A treatment on the horizon for high Lipoprotein (a)? After chemotherapy to help shrink a tumor near my husband's spine, he now has numbness and neuropathy in his legs Another study implicates meat, and now poultry and fish, in causing cardiovascular disease What do you think of Consumer Lab's recommendations on supplements? I take CoQ10, but I just heard about PQQ. What are your thoughts?
