Negative Effects of Too Much Vitamin D


اردو میں پڑھیں

Vitamin D, one of the thirteen essential vitamins, is needed for positive bone and teeth health.  Many times, it is associated with calcium because when taken together, vitamin D increases the absorption of calcium. Vitamin D can be found in dairy products, cereal, eggs, and fatty fish.  It is also produced by your body when exposed to the sun.  With that being said, sunscreen should always be worn during sun exposure.  While it is a necessary vitamin, too much vitamin D can be harmful.  Usually, supplements with vitamin D are the main culprit behind overdoses, rather than too much sun exposure.


Vitamin D toxicity symptoms include nausea, vomiting, weakness, and confusion.  It can also affect heart rhythm and kidney function. While vitamin D overdose is not common, it is still something to be aware of when taking your multivitamin or supplementing with vitamin D for bone support.  Consult with your physician or pharmacist to discuss the correct amount to consume daily.  Always discuss any changes in medications with your physician, which include changing multivitamins or supplements. To check your vitamin D level, connect with Shifa4U.
