I've been dealing with autoimmune issues for a while now. After doing many hours of research I've come to the conclusion that it's most likely caused by deficiencies in vitamins A,D,K2 so I recently have been playing around with different doses of D3 w/K2 MK7 and A from Liver. After starting these things I noticed I would get constipated, not terribly, but noticeable enough for me to wonder why. I've ruled out it being caused by the vitamin D & A and I'm 95% sure it's because of the K2 MK7. Why would this be happening? The only other supplement I take is 500 mg of Magnesium Glycinate and have not experimented with MK4 yet but wondering what you guys think of switching over and if that might fix the issue.
