Unfortunately, a meta-analysis will frequently fail to consider one or more of the following
- Dose size (Some gave the same importance to 40 IU as 10,000 IU)
- Dose frequency (Some ignore differences between daily, weekly, monthly, and annual dosing)
- Duration, (Some gave same importance to 4 weeks as 4 years)
It takes 3 to 12 months for vitamin D levels to come to a new plateau
and it often takes months for the body to then utilize it - Pre-existing Vitamin D blood level
adding vitamin D does not provide much benefit if person alrady has a good level - Cofactors (Most meta-analyses ignore the importance of Magnesium, Omega-3, Vitamin K2, etc)
- Type of Vitamin D - D3 far better than D2
- Those with poor guts need a different type of vitamin D
- Those who are Obese need 2.5 X more vitamin D
- Many drugs, such as statins deplete vitamin D or the Magnesium needed by Vitamin D
- For some health problems pulsed vitamin D, not daily, is far better (gets over possible Vitamin D receptor limitation)
