A recent study conducted by the National Health and Nutrition Examination Survey (NHANES), found that Increased levels of vitamin D may improve cardiovascular health and reduce the occurrence of peripheral arterial disease (PAD).
PAD is associated with decreased blood flow in the legs, and occurs when arteries in the legs become narrowed or clogged with fatty deposits. According to 2008 statistic from the American Heart Association, PAD affects about 8 million Americans and is associated with significant disease and death.
Blood levels of 25- hydroxyvitamin D (25(OH)D), the non-active ‘storage’ form of the vitamin, was correlated to the prevalence of PAD among the participants. The average age of the “large nationally representative study sample” was 61.2.
When the researcher divided the sample into four groups according to their 25(OH)D levels, and found that increasing levels of the vitamin were associated with lower prevalence of PAD, from 8.1 per cent in the group with the lowest 25(OH)D levels, to 5.4, 4.9, and 3.7 per cent across the ‘quartiles’ with increasing vitamin D levels.

When the researchers adjusted for age, sex, race and co-existing health problems, they found that PAD was 64% more common in the group with the lowest vitamin D3 levels compared with the group with the highest levels. For each 10 ng/mL drop in vitamin D level, the risk for PAD increased by 29%.
Moreover, the relationship was consistent across the difference subgroups. The authors note that the relationship does not prove that increased levels of vitamin D protect against PAD directly, and that higher vitamin D3 levels may be a marker of general or specific lifestyle practices.
