I have had dramatic success with K2, which I think is being knocked out due to my gut problems. Lately my Hg has gone down a bit and I don't know if this is because I have taken my eye off the ball a bit and have skipped supplements and been slacking with diet, or something else.
Next thing I am planning to try if my Hg carries on going down is low dose naltrexone. Theory being that this will address gut inflammation.
Am a terrible stress-monger, and am trying to work on this aspect too!
