Unilever USA filed the petition in August 2003, along with published human clinical trials on vitamin D and estimates of dietary intake of vitamin D from natural sources and current and proposed uses.
Vitamin D occurs naturally in foods including dairy products, eggs, fish, meat fats and organ meats and mushrooms, and is also produced by the body with exposure to ultraviolet light.

Some more information about Vitamin D. Vitamin D3 is what we get from the sun when we sun oursevles. It is more potent than Vitamin D2 (which is found in dairy products). As WG patients, a lot of us have Vit. D deficiencies due to treatment. I usually take Calcium with Vit. D supplements.
Since getting WG, I have found that I really need supplements. It is possible that this is a problem with anyone who has to take certain chemo drugs.
