RCT suggests over 65s need 4,000 IU vitamin D daily for disease prevention

[Clutter]

This study possessed several strengths. The participants were deficient at baseline, the study duration was long and the dosage enabled the participants to reach optimal vitamin D status (40-60 ng/ml). The primary limitation of this study is that most of the participants were Caucasian, thereby decreasing the generalizability of their findings. Additionally, participant’s compliance decreased over time, a common challenge of long-term trials.

The researchers concluded,

“After taking account of the typical average 70% compliance observed in long-term trials of vitamin supplements for disease prevention, the results of the present study suggest that daily doses of 4000 IU of vitamin D3 may be required to achieve the high plasma levels of 25(OH)D associated with the lowest risks of mortality in the observational studies.”

To convert ng/ml to nmol/l multipy the ng/ml figure by 2.5.

Take your vitamin d with 400 mg magnesium citrate. I think you will be able to tolerate it better then.
