Update 2015 - Good Health is more than Vitamin D and cofactors – my view

Magnesium is probably the most important cofactor

Notes as of April 2013

  • It is OK to take lots of vitamin D for a month or two (Even 50,000 IU daily for a month)
  • The first cofactor to consider to take would be Mg - as <1% of people get allergic reactions to vitamin D due to being very low on Mg
  • Cofactors in a nutshell: Calcium 500, Magnesium 500, Vitamin K-2 100 (or more)
  • Probably the milligrams of most cofactors, as well as IU Vitamin D, should vary with the weight

Looked at more than 100 suppliers of vitamin D liquid and solid co-factors Dec, 2010 - Feb 2011

  • Daily dose sometimes < 30 cents

Adequate amount of most co-factors and LOW cost:

SOLID: 2 or 3 pills per day: Strontium Osteo, ABC to Z (2x), etc. for about 35 cents per day

LIQUID: Osteo Density: 21 cents per day

SOLID summary

This is a small portion of the spreadsheet (attached at bottom of this page)


None of the solid (or liquid) co-factors are perfect

Jarrow Bone-Up ULTRA has 2X more vitamin D3 and vitamin K2 than the non ultra version - continues to lack vitamin A

Vitamin A can perhaps be skipped (get it in food), or is very low cost to get as a separate pill

The lowest cost, Osteo Density, also happens to have a fairly good set of co-factors
