I have taken Vitamin D3 at 2000 units for years. I recently had my plantar fasciitis flare up to a point that I could hardly walk. In researching possible remedies, I came across a YouTube video from an orthopedic doctor who recommends taking 10,000 units to help with inflammation.
Like everything else, the topic is rife with counter opinions. 10,000 units seems very excessive to me, but other people swear by it. Thoughts?
Vitamin D toxicity occurs when vitamin D levels in your body are so high that they cause harm.
Healthcare professionals may also call it hypervitaminosis D.
Vitamin D is a fat-soluble vitamin. In contrast to water-soluble vitamins, your body has no easy way to get rid of fat-soluble vitamins.
For this reason, excessive amounts may build up in your body.
The exact mechanism behind vitamin D toxicity is complicated and isn’t fully understood at this point.
However, we know that the active form of vitamin D functions similarly to a steroid hormone.
It travels inside cells, telling them to turn genes on or off.
Usually, most of your body’s vitamin D is in storage, bound to either vitamin D receptors or carrier proteins. Very little “free” vitamin D is available (1Trusted Source, 2Trusted Source).
However, when vitamin D intake is extremely high, your levels can become so high that there isn’t any room left on the receptors or carrier proteins.
This may lead to elevated levels of “free” vitamin D in your body, which may travel inside cells and overwhelm the signaling processes affected by vitamin D.
One of the main signaling processes has to do with increasing the absorption of calcium from your digestive system and bones (3).
As a result, the main sign of vitamin D toxicity is hypercalcemia, or elevated calcium levels in your blood (4Trusted Source, 5Trusted Source).
High calcium levels can cause various symptoms. The calcium can bind to other tissues, including your kidneys, and damage them.
