I believe I can vouch for this.
Over the summer, I was taking dairy products and outside a LOT for hypocalcemia, getting plenty of vitamin D in. In the last few month, I had some symptoms that were puzzling: my hair was falling out, I had a growing problem with insomnia, and was having breathing issues. Just couldn’t get deep breaths in the way I was.
On Christmas night, I wound up in ER thinking I was having a stroke or heart attack. Turns out the calcium in my blood dropped off and the phosphorus levels were high (turned out to be hypoparathyroidism). So started taking Oscal and calcitriol, a prescrip vitamin D, which I’ll be doing for the rest of my life.
All my odd symptoms had reversed, including my breathing issues. I can breathe in nice and deep again and no longer am having problems with it at night.
