Study supplemented those with low vitamin D with 20,000 IU weekly for just 4 months
20,000 IU weekly = 2,900 IU daily
Many studies are recommending that everyone needs at least 4,000 IU daily for health

OBJECTIVE:
Low serum 25(OH)D levels are associated with cardiovascular disease (CVD) and some of its risk factors. However, in interventional studies the effects of vitamin D supplementation have been uncertain, possibly due to inclusion of vitamin D sufficient subjects. Our aim was therefore to examine effects of vitamin D supplementation on CVD risk factors in vitamin D insufficient subjects.DESIGN: Double-blinded randomized controlled trial.
METHODS: A four months interventional study with high dose vitamin D (100 000 IU loading dose, followed by 20 000 IU/week) or placebo with measurements of:
- blood pressure,
- lipids (total-, LDL- and HDL-cholesterol, triglycerides, apolipoproteins A1 and B ), and
- glucose metabolism parameters
(blood glucose,HbA1c, sRAGE (minor improvement), insulin, C-peptide, and HOMA-IR).
RESULTS:
422 subjects with mean serum 25(OH)D level 34 nmol/L were included, with 411 subjects completing the study. Serum 25(OH)D levels increased with 56 nmol/L and decreased with 4 nmol/L in the vitamin D and placebo group, respectively. We found no statistically significant differences between the two groups in any of the measured CVD risk factors, except for a minor increase in sRAGE in the vitamin D group.
Stratified analyses of subjects with low baseline serum 25(OH)D levels alone, or combined with blood pressure, lipid and HOMA-IR values above the median for the cohort, did not skew the results in favour of vitamin D supplementation.CONCLUSION: Supplementation with vitamin D in subjects with baseline vitamin D insufficiency does not improve CVD risk factors profile.
