    You Ask, I Answer: Vitamin D Production

    300px-Sol_de_Mayo-Bandera_de_Uruguay.svgHow much Vitamin D does our body make from the sun?

    Shouldn’t that be the amount we try to get from supplements?

    Our bodies can synthesize up to 10,00 International Units of Vitamin D from sunlight.

    Remember, our bodies are intelligent enough to know when to stop Vitamin D production (if not for these self-regulatory mechanisms, we could potentially synthesize millions of International Units per day, which would be very harmful.)

    The fact that we can safely take in 10,000 International Units does not mean we should aim to get that much from supplements in pill form.

    That figure is considered the Upper Tolerable Intake — “the highest level of daily intake of a nutrient that is likely to pose no risk of adverse health effects for most people.”

    The research literature on Vitamin D clearly shows that daily intakes of 1,000 International Units provide the necessary health benefits for most people (some individuals, like expecting mothers and the elderly, have shown to benefit more effectively with supplement ranging from 1,500 to 2,000 International Units a day).

    I strongly agree with nutrition scientists who are flabbergasted by the ridiculously low curret recommended Vitamin D intakes.  They need a major overhaul… ASAP.

      Kind of nifty calculator to use to see how much sun exposure you need to get 1000 IU Vitamin D:

      and this may help you use the calculator:
