One pill every two weeks gives you all the vitamin D most adults need

    Our Does Less Sun mean More Disease video tells you WHY vitamin D is needed

Taking one 50,000 IU capsule of Vitamin D3 every two weeks will result in 80% of adults bringing their blood levels to above 40 nanograms/ millliliter, an optimal level for good health.
A 50,000 IU capsule is the equivalent of the amount of vitamin D from sunbathing for 3 days in a sunny climate.

You can take more 50,000 IU pills initially to feel the benefits more quickly.

50,000 IU To feel benefits in a weekTo Maintain 40 ng/ml
Adult2 per day for 4 days 1 every 2 weeks
Adult - high risk* 4 per day for 4 days 1 every week

*About 20% of adults are at high risk for Vitamin D deficiency: especially those who are obese, pregnant, shut-in, avoid the sun, have dark skin, are senior, live far from the equator, or need to deal with an illness, injury, or surgery. They need at least 2 times more Vitamin D.

A 50,000 IU capsule costs as little as 21 cents, ($21 retail for a bottle of 100 capsules Amazon US )
The very lowest cost source and highest quality of vitamin D3 50,000 IU capsule = Bio-Tech
You can order it from Amazon US (Amazon has the lowest price, but has a policy to not ship any drugs out of a country)
     Bio-Tech 50,000 was 2nd highest rated Vitamin D in Amazon May 2014

   * Here is a UK company that ships Bio-Tech products to all the European countries

  WLS sells Bio-Tech with a different label from the Netherlands
- Many companies supply Vitamin D, not just Bio-Tech
    Amazon (US) Vitamin D as of Oct 2014: 5 supply 50,000 IU, 30 supply 10,000 IU, > 500 supply 5,000 IU
- An adult who is not at high risk for vitamin D deficiency can achieve an optimal level for $1.60
    and maintain it for just 2 cents per day (Amazon price: 20 cent capsules)
- If at high risk: at least double the amount will be needed (at double the price)

Bio-Tech makes the only Vitamin D which has ALL of these features:
