How often might 50000 IU vitamin D be taken - results of clinical trials


There have been many extremely successful vitamin D intervention trials.
Often the trials are random-controlled and double-blind: neither the doctor nor the subject knows who gets it
The trials are listed in the following table are sorted by the number of days between doses of 50,000 IU.
It appears that the higher the dose of vitamin D the more diseases which are prevented or treated.

Following curve indicates that probably want to take 50,000 IU of vitamin D at least every two weeks.

50000 IU monthly is not a lot

Notes on 50,000

  • Lowest-cost form of vitamin D3 (about 2 cents per 5,000 IU)
  • The half life of vitamin D3 is measured in weeks - so taking 50,000 every few weeks is OK (half life of vitamin D2 is measured in days)
  • This is the size of vitamin D that doctors have been used to prescribing for many decades - generally as a loading dose every week or two.
  • Now doctors can prescribe Vitamin D3 instead of D2
  • This has has very low toxicity - even if accidentally taken daily, the toxicity does not occur until it has been taken daily for 3 months
  • Can be even used by those who cannot swallow pills (the powder in the capsule is tasteless and can be taken directly or in food or beverage

Cofactors appear to be needed if dosing more frequently than every 20 days for months

Easy to remember to take vitamin D - just mark your calendar
