In this post today, i will be discussing what happens to your body when you take too much vitamin D, you might not know these things but they are there building up day by day. Right now, vitamin D is hot as many doctors, registered dietitians, and other health experts are saying it could lessen the severity of COVID-19 symptoms.
Why? The vitamin is known to help support the immune system by decreasing inflammation in the body caused by the virus. However, Ali Webster, PhD, RD, Director of Research and Nutrition Communications, International Food Information Council, points out that vitamin D may not be the end all be all.
“Recent reviews of literature on the topic say that sufficient evidence to support vitamin D supplementation for the prevention or treatment of COVID-19 is still lacking,” she says. And this is Why you should kick these 6 foods out of your freezer right now
Still, taking a vitamin D supplement can’t hurt you, that is, unless you overdose. Adult men and women are encouraged to consume 15 micrograms (mcg) or 600 international units (IU) of this vitamin each day, Webster says. For those over 70 years of age, the recommended dietary allowance is 20 mcg or 800 IU.
In some cases, health care providers will prescribe higher doses of the supplement to patients who are deficient or low in this vitamin. However, taking high doses when your levels are fine is not necessary and could also be dangerous to your overall health.
“Before starting a supplementation regimen, it’s important to consult with a health care professional and make sure that your vitamin D status is continually monitored to assess any changes that may need to be made after you begin taking the vitamin,” she adds.
Below, you’ll see five potential side effects of excess vitamin D.
Since vitamin D is a fat-soluble vitamin, which just means it’s better absorbed and transported in your body if it’s consumed with fat. This, in part, makes it possible to consume in toxic amounts. Webster explains that this vitamin increases the uptake of calcium in the bloodstream which can cause a variety of issues. One such issue is nausea or, even vomiting.
If you’re starting to feel nauseous while taking supplements, this could be an indication that you’re taking too much of the fat-soluble vitamin.
Webster also says you could also be at risk of experiencing dehydration when taking overdose of it. As Sakiko Minagawa, MS, RD, LD told Eat This, Not That! In 7 Side Effects of Not Drinking Enough Water, signs that indicate you aren’t drinking enough water include a rise in body temperature, drop in blood pressure, muscle cramping, and constipation. If any of these symptoms are prevalent and you’re also taking this vitamin, consider taking a few days off and then resume by halving the dose.
Vomiting and dehydration can leave you feeling weak, but taking too much of it can also lead to unexplained exhaustion. You may even experience a loss of appetite, which could also make you feel fatigued.
Another risk factor in taking excess vitamin D is the development of kidney stones. Why? As Webster said, vitamin D increases the uptake of calcium from the gastrointestinal tract, which can then lead to too much of the mineral in the bloodstream. Kidney stones forms when have too much calcium in your blood.
In the worst-case scenario, meaning the most severe instances of vitamin D toxicity, Webster says you could experience heart abnormalities. However, you would have to be taking well over the recommended amount—specifically through supplementation—to ever feel this dangerous side effect.
“It’s important to note that excessive intakes of vitamin D are primarily the result of misusing dietary supplements,” she says. “It’s not thought to be possible to get overdose of vitamin D from sun exposure, and since vitamin D is in relatively few foods, consuming toxic amounts of it would be very unlikely.”
