Researchers warn Vitamin D supplements can be harmful – WTXL ABC 27
(WTXL) – It’s the first day of summer and despite rain in the Big Bend, the sunshine is on the minds of a lot of people.
Supplementing sunshine with Vitamin D tablets may be doing more harm than good for a growing number of Americans.
According to researchers, 3 percent of American adults are supplementing at doses linked to serious side effects, including kidney stones, cancer, and even death.
While Vitamin D is generally a good thing, it helps with calcium absorption and maintaining phosphate levels in the blood.
Too much Vitamin D can damage soft tissues, including kidneys and the heart.
The National Institutes of Health says the amount of Vitamin D you need each day depends on your age.
Ages 1 to 70 years old need 600 international units, adults 71 and older need 800 international units.
