I take quite a variety of supplements, but I’ll mention only a few of the most important. Among the most important to me are vitamin D3 (5000 IU, x2/d) enough to keep my blood level of 25(OH)D up to 80 ng/L; a daily probiotic, Once Daily Men’s (50 billion CFU, 15 strains) good for colon health and immune system; and three herbal formulations recommended by my acupuncturist: Bu Zhong Yi Qi Tang (a ginseng & astragalus combination among a blend of about a dozen other extracts) whose purpose is to tonify energy (Qi) and digestion; Salvia 10 Formula, whose purpose is to regulate digestion. I don’t take these two formulas at the same time. I take one for about 15 days and take the other one for 15 days. And also when I take them, I am “on” them for 5 days and “off” them for 2 days. Each one of these formulations is paired with a third herbal formula, Lycium Formula (aka Huan Shao Dan), whose purpose is to tonify the kidneys.
I also take nattokinase (Nattovena, 4000 FU) about every 12 hours as per label directions for the purpose of minimizing formation of micro clots, as a stroke-preventative; it is also probably effective for canceling out bad effects from a early stage COVID-19 infection. I previously took serapeptadase for the same reason, but I deduced that it was causing me to have hives. Once I stopped taking it the hives disappeared.
I also stopped taking quercetin, since I learned that it has a substantial blood-thinning effect, not advisable when simultaneously taking something like nattokinase and other supplements that might thin the blood. That advice came from AI (Perplexity.ai). Also contributing to my decision to stop the quercetin was an event that occurred during a recent dental procedure when my dentist told me that he had a challenge controlling bleeding while he was replacing a crown. (I am not willing to stop my nattokinase; I think it is a lot safer than taking doctor-prescribed blood thinners, such as Eliquis. The nattokinase may not be as effective as Eliquis, but it doesn’t have the serious adverse effects, if the user exercises reasonable precautions.)
