VITAMIN D EXCESS

Taking very high daily doses of vitamin D over several months can cause toxicity and a high calcium level in the blood (hypercalcemia)

Early symptomsoms are loss of appetite, nausea, and vomiting, followed by excessive thirst, weakness, nervousness, and high blood pressure.

Because the calcium level is high, calcium may be deposited throughout the body, particularly in the kidneys, blood vessels, lungs, and heart.

The kidneys may be permanently damaged and malfunction. As a result, urination increases, protein passes into the urine, and the level of urea (a waste product) increases in the blood. Kidney failure may result.

Excellent info, thanks LucyT.

I'm probably going to take only 200iu daily because some foods are vitamin-D fortified already and I eat a lot of (deep-sea) tuna.

Thanks. Damned if you do and damned if you don't. Same with sun blockers.

Thanks, Lucy. This is good to know. Have to stick to the middle way.
