Noticed Mar 2012 Vitamin D3 and many co-factors in one pill 5,000 IU per serving of 3 capsules

50,000 capsule is a very low cost way for a person to take vitamin D3 once a week

  • 20 cents per 50,000 IU capsule taken once a week ==> 7100 IU per day average = 3 cents per day
  • There appears to be no reason not to take vitamin D3 once per week
  • There have been many studies showing that taking it once every 4 weeks is not a problem either
  • But those studies were not done with high levels of vitamin D, and there are some indications that the half-life is much shorter for high levels.

Bulk (powder)

vitamin D costs about 1.2 cents per 5,000 IU
http://purebulk.com/vitamin-d3-cholecalciferol They sell a wide variety of supplements in bulk
They appear to buy 1,000 KG vitamin D wholesale (2200 lbs) and re-sell it in amounts of 100 gm to 25 kilogram
Smallest amount which they sell is 100 grams = 10 million IU (100,000 IU = 1 gram ) for $20
Cost of 4,000 IU for 1 person year = $3.00 (1.5 million IU X $20/ 10 million IU)
1 person year = 4 persons/3 months = $3.00, so 4 persons for 1 month = $1
10,000,000 IU for $23 ; so 5,000 IU = 2300/2000 = about 1.1 cent per 5,000 IU

Large quantity:25 kg for $3,336 =13 cents/gram (vs low quantity price = 20 cents/gram)
Note: Annual cost of vitamin D for a cow getting 40,000 IU per day is $1, which is 10X cheaper than from Pure Bulk (25 kg size)
   4,000 IU/dayfor humans at "cow prices" cost would be 10 cents for entire year ($1 X 4,000 IU/40,000 IU)
   see Vets and vitamin D

  • Note: this is NOT pure: cut 400X to 1 by manufacturer. Thus It is not 40 IU per microgram, but rather 0.1 IU per microgram
