I’ve been looking for something like this for a long time. Thank you. As for the personal experience, I’ve tried almost all of the aforementioned items. The greatest effect I experienced was from taking Fish oil and concentrated nitrates (unfortunately haven’t found it in the list). Though from all the possible forms of the nitrates the beets pills are the most acceptable one. It has the lees effects on liver and I experienced the general energy rise after a week.
