A member asked:

Is taking 10,000 iu of vitamin a safe for long term or will it build up in the liver and become toxic?

A doctor has provided 1 answer

Too much: 1000 or 2000 units is commonly used. Your dose is too high and could cause problems. You can reduce the guesswork by getting a blood test for blood level of Vit D. Recent studies favor OTC vit D3 rather than the 50 000 unit D2 pills.
