Hypertension following Vitamin D supplementation

[lift]

I normally have mild hypertension 135-150/85-100. But following a 10 day supplementation of vitamin D which would have totaled 115,000IU(5000-15,000 IU per day) I had a case of what would be classed as severe hypertension 165-178/95-115. It lasted around 7-10 days and now my blood pressure has returned to the original mild hypertension range.

From what I have read vitamin D deficiency can cause hypertension and I do actually have low vitamin D, hence the supplementing. But also Vitamin D toxicity can cause hypertension. There's 3 possible reasons I have come up with for the cause of the hypertension:

1) Vitamin D causing magnesium depletion
2) Short term vitamin D toxicity
3) coincidental and unrelated to vitamin D supplementation.

Early on(day 2-7 of supplementation) I felt my mood was better and it felt like the bone pain in my feet that i notice in the mornigns went away. It could have been placebo.

I have issues with Vit D, in my case is allergy like symptoms, I am mutated in the VDR gene (I think is the Vit D one). I am low but I felt so miserable on it that I just go outside and get sun instead. But what kind of D are you doing D3????

Large doses of vitamin D can cause hypercalcemia. Have you checked for elevated serum calcium? What are your normal levels of vit D like? Have you tested for elevated PTH, it can increase conversion to the active form and increase serum calcium.
Vitamin K2 MK-4/vitamin A should work to lower the calcium.

I was taking Now's vitamin d3 cholecalciferol

Rwac, that was one of the theories I had actually. However, during my severe hypertensive period I had a blood test done that showed that calcium I think was 9.86 and Parathyroid was 3.5, smack bang in the middle of the range. I was actually disappointed that I dont have hyperparathyroidism. It seems like an easy fix.

Do you have units and a range for those values?

Might be worth trying vitamin A(retinol), K2(MK4) and perhaps vitamin E(vegetable oil free for best effect). All of them will reduce blood pressure.
