I've been taking the Thorne ResveraCel supplement, which includes Nicotinamide Riboside, Quercetin, and a pinch of TMG.
In reading more about Quercetin, I found:
https://www.ncbi.nlm...pubmed/26106459 -- It looks like heart mitochondrial function was impaired with lower serum antioxidant capacity.
https://www.ncbi.nlm...pubmed/25091043 -- Prevention of mitochondrial biogenesis from exercise.
https://www.ncbi.nlm...pubmed/24118142 -- Prevention of muscle adaptation to exercise.
https://www.ncbi.nlm...pubmed/14660033 -- Reduced liver glutathione.
This is making me second guess the stack. What are your thoughts? Do you guys have any other suggestions?
