Any possible problems from too much vitamin D?

Expand full comment

It is possible to get hyperglycemia where calcium builds up where it shouldn't, but this is unlikely without regularly taking 30,000+ IU and without having magnesium and vitamin K2.

When over dose testing was done problems weren't seen till about 300 ng/ml and were immediately reversible by stopping supplementation.

I got up to about 150 ng/ml with no problems and I didn't get sick for several years. Since dropping down to about 80 ng/ml I've gotten sick because of majorly over doing things and getting run down.

Stupid autocorrect changed hypercalcemia to hyperglycemia. Sorry. I always need to proofread before submitting.

See the Coimbra Protocol they work with very high dose vitamin D and take some precautions e.g. regular blood tests etc.
