What are some side effects of vitamin d supplements at 2000u per day?
A doctor has provided 1 answer
Several: Too much vitamin d can be bad for you and can cause serious problems. Side effects may include high calcium levels, elevated kidney function, nausea, vomiting, decreased appetite, weakness, and increased urination. Total intake from all sources, food and supplements should remain less than 4000u to decrease risk of adverse events, although they can happen at any dosage.
