Wondering if you have considered using holistics that are suggested by the National Institute of Health.
95% curcumin with black pepper extract for bioavailability is a powerful anti-inflammatory and immune system builder as well as positive affects for many health conditions. It is water soluble so can be taken in high doses at 3-4 hour intervals with no adverse reaction.
I was taking chemotherapy for stage II invasive bladder cancer when exposed to Covid and tested positive. Was already on high dose curcumin to more effectively fight cancer. Not only no adverse side effects from chemotherapy, but no symptoms of covid ever and am now cancer free.
