May 15, 2020 — Hello Mr Bowles,

I hope all is well. Just a couple observations for you:

I got up to 120000iu of d! It made me stiff a lot like 10000 once did. Also my tennis elbow was becoming unbearable, I couldn’t lift a pencil! At 120000iu d I took 20000iu of a and would have tried more but 12 doses of k2 was causing pins and needles in one leg and my hands during exercise and I was too stiff, had to back off. Now 50000 iu d with 10000iua is working well, tiny little shoulder Charlie horse when stretching in the am otherwise no issue at 50000iu d w 10000iu a and 600mg borax.

I’m now at 800mg borax, my hips went from aching pain in the day to extreme sharp pain during the night, taking boron, to extreme pain for 20min in the am to now I’m almost 100% cured in about 7 months! I’ll be writing something up for you soon.

I thought when I increased d my magnesium deficiency symptoms would get worse, instead they shifted. At low levels I feel magnesium deficiency in my legs and jaw, at higher levels in my shoulders and upper back and at the highest levels it affects my mind.

I have two friends my age taking d and both can’t get past 4000 due to stiffness.  Pretty small sample size lol. But My sensitivity to d seems to be the norm for people our age.
