Nattokinase Day 4 of 21

Day 4 of a 21 day regiment of 4000FU's of Nattokinase (2 pills daily). If I had gotten the MRNA treatment, I would have decided on a 90 day regiment. No foot cramps, no hand cramps, even in situations I would have expected it. The purpose of this treatment for me is that I was inclined to believe I never fully recovered from covid (exposed 1/26/2020, manifesting symptoms the evening of 2/10/2020).
