Vitamin D Overdose - Discover How Does Vitamin D Toxicity Occur and What Are the Tolerable Upper Intake Levels

Vitamin D overdose or the consumption of too much of vitamin D is associated with many health risks. It is also referred to as vitamin D toxicity.

How Does Vitamin D Overdose Occur?

Vitamin D toxicity is unlikely to occur through the consumption of a normal diet alone. It can occur if you are consuming high amounts of vitamin D rich food sources such as cod liver oil on a regular basis.

Too much consumption of vitamin D in the form of supplements is also another reason why vitamin D toxicity may occur.

Tolerable Upper Intake Levels (UL) for Vitamin D

According to the Food and Nutrition Board of the Institute of Medicine, the tolerable upper intake levels (UL) of vitamin D are as follows --

• For infants below 12 months -- 25 mcg or 1000 IU
• For adults, children, pregnant women and lactating mothers -- 50 mcg or 2000 IU

A daily intake that exceeds the tolerable UL is not advisable as it exposes us to a greater risk of adverse and serious health effects.
