Q. My blood level of vitamin D (16) is very low. A few years ago I was prescribed 50,000 IUs once a week, but I had to quit after just one month. It caused severe acid reflux that took me several months to get under control.
I’d feel a lot better if I could get my vitamin D levels up, but how can I manage that with my hypersensitive stomach? Using acid suppressors over a period of time creates a rebound reflux that really makes things worse. I’d appreciate any suggestions you can offer.
A. With such a low level of vitamin D in your body, you would probably feel better if you could bring it up. Low vitamin D has been linked to asthma, infections, depression, joint pain, heart disease and high blood pressure, among other problems.
You might want to try a lower dose of vitamin D3 to see if you can tolerate it. The earlier medication you took was vitamin D2. Vitamin D3 is available OTC in doses such as 1,000 or 2,000 IU.
Now that spring is here, you might also want to get 15 or 20 minutes a day of sun exposure. We are sending you our Guide to Vitamin D Deficiency for more details on the pros and cons of this essential nutrient. We also describe the appropriate levels of 25-hydroxyvitamin D, the test that showed your body is so low in this vitamin.
Although vitamin D is not supposed to cause side effects, you are not the only person to report difficulties, particularly with the high-dose once-a-week regimen. Anyone else who has had a reaction to vitamin D may report it in the comments below.
