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.

Human & animal studies show that animals & our human ancestors got 5,000-10,000 units of Vit.D every day from 2-4 hours of outside UV sunlight exposure without clothes.There is about zero chance of that with today's parents slathering UVB 60% Protection Suntan lotion on any child who moves.Protect your skin and your children but you must get Vit.D 5,000-10,000 from somewhere.
FYI -No Vit.D-No life

It's been estimated that 70 percent of children & adults in the U.S. are vitamin D deficient. The cause of deficiency is a combination of not getting enough exposure to the sun & not having enough vitamin D in their diets. .Because there are only small amounts of vitamin D in food there are only two sure ways to get enough vitamin D:
Exposing your bare skin to sunlight to get ultraviolet B (UVB)

1-2 grams: It appears that most publications recommend a daily amount of 1-2 grams a day. You may need more depending on age, bone mass and amount of dietary vitamin d and sunshine your get. Talk to your pcp about this. You may need more, you may not need any. My dose seem mostly accepted.
