Brian February 20, 2017 at 10:47 pmI am an autistic adult who was not diagnosed until I was 28. I am now 32. I started taking 15,000 IU of D3 8 months ago and it has almost totally normalized my behavior. I must take 15,000 IU. Anything less, and my ability to socialize drops off a cliff.
Also, I can only tolerate small amounts of vitamin A. Up to 2,000 IU but no more. And I cannot tolerate ANY vitamin K2. I tried taking 15mg of K2 on the recommendation of Thomas Levy but I had severe side effects from this. Severe back pain, nausea, and I couldn’t stand for long periods.
Also, I feel much better when I combine the high vitamin D with high levels of calcium. I get about 2500mg of calcium by drinking lots of milk. I can only take small amounts of magnesium before I start getting similar symptoms to the ones I get with vitamin K2.
I suspect you are correct about the ratio of the two forms vitamin D. I also think autistic people may have a greater need for calcium for several reasons. One being a greater endogenous production of oxalates. It could also be that we need more calcium in the diet because we have a more difficult time absorbing it.
