Nattokinase is also great in combination
Might you be the one who told me about a “vein scrubber” substance.
natto has lots of vitamin k2—which you want to pair with vitamin d3. the k2 increases the amount of HDL —which in turn shovels the plaque out of your arteries.
the other common pairing is b12 with omega 3. these two together are protective against alzheimers.
