How much Vitamin D is normal?

If you have gone to a lab and got your vitamin D levels checked, you might have seen the normal range of vitamin D. It’s expressed in the unit of nanograms per milliliter(ng/mL). Most people just do dine in the range of 20 to 40 ng/mL but it’s recommended to have between 30 to 50 ng/mL for proper bone and overall health.

Most the people today are deficient in Vitamin D. The reasons include one or more of the following –

Side effects of too  much vitamin D

Though high doses are safely tolerated by most people when taken orally, when administered through a syringe can have bad side effects. The main problem with too much Vitamin D is the calcium buildup in the body(hypercalcemia). It can lead to kidney stones as well. In my past experience when I was administered megadoses of vitamin D through a syringe, I suffered from too many kidney stones.

Other symptoms include weakness, vomiting/nausea, dry mouth, and others.

How much Vitamin D to take in supplement

It varies on the condition you have and your current vitamin D3 (25OHD) levels). Usually, 1000 to 2000 IUs a day are good enough for healthy adults but the upper limit is up to 10,000 IUs per day (earlier it was 4,000IUs per day) are safe for adults taken orally (recommended by The Endocrine Society Practice Guidelines).
