Pharmacist issues warning to anyone who takes Vitamin D

She said: “Don’t take too much vitamin D. Because it’s a fat soluble vitamin it can build up in your body easier than other vitamins.

“Taking too much vitamin D long term can lead to hypercalcemia, an excess of calcium in the body, which can cause problems with your heart, kidneys and bones. 4,000 IU or 100 mcg is considered to be the upper limit of safe vitamin D supplementation.”

The NHS also warns not to exceed 4,000 IU, adding: “Do not take more than 100 micrograms (4,000 IU) of vitamin D a day as it could be harmful. This applies to adults, including pregnant and breastfeeding women and the elderly, and children aged 11 to 17 years.”
