Re: 5,000 IU a day of Vitamin D - too much?

Hello Quinta_Essentia

Thought I'd give Tony a hand on this one.

This is the prevailing view of Vitamin D intake by the Vitamin D Council............

"If you totally avoid the sun, recent research indicates you need about 4,000 units of vitamin D a day. Which means you can't get enough vitamin D from milk (unless you drink 40 glasses a day) or from a multivitamin (unless you take about 10 tablets a day), neither of which is recommended.
Most of us make about 20,000 units of vitamin D after about 20 minutes of full body exposure to the summer sun.

This is about 100 times more vitamin D than the government says you need every day.

The only way to be sure you have adequate levels of vitamin D in your blood is to regularly go into the sun, use a sun bed (avoiding sunburn), or have your physician administer a 25‑hydroxyvitamin D test. Optimal levels are around 50 ng/mL (125 nM/L).
If you don't get vitamin D the way Mother Nature intended, from sunshine, you need to take supplemental vitamin D3 cholecalciferol. Since most of us get a lot more vitamin D from sunshine than we realize, most of us need about 2,000 units a day extra."

Just make sure that the Vitamin D you supp-le-ment with is Vitamin D3 or "cholecalciferol", which is much more bio-available for mammals.
