Introduction

669 Meta-analyses

See also Overview Meta-analysis of Vitamin D
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)

". . . they have mixed apples and oranges—and sometimes “apples, lice, and killer whales”—yielding meaningless conclusions"
"In a 2007 review of 111 industry-funded (nutrition) studies, funding source was significantly related to study conclusions"

VitaminDWiki Comment on Scientific American article

It does not mention the major problems of Vitamin D Meta-analyses.
1) Dose sizes are ignored: Studies assume benefit from 400 IU is the same as for 4,000 IU
2) Durations are ignored: Studies assume benefit of 1 month dosing is the same as 1 year dosing
3) Existing Vitamin D levels are often ignored.
Studies ignore that a 20 ng addition to a 10 ng person has vastly more benefit than a 20 ng addition to a 40 ng person
A rare example of a good meta-analysis is: one on depression - April 2014

Really great medical studies do not blindly give a single supplement/drug to a group, but rather treat the patients as individuals and provide extra Magnesium, Vitamin K2, Omega-3, Vitamin C, etc as needed. These studies, which have the best results, are not Random Controlled Trials and are virtually never included in a meta-analysis.

Likewise, the trials which give vitamin D to an entire country, or to all of the patients (immoral not to do so) are never considered by any meta-analysis

Vitamin D has climbed the pyramid for decades, but has not yet reached the top
