Vitamin D Research

29 11 2009

Our Vitamin D product from XCAP (Xtreme Couture Athletic Pharmaceuticals) is called Vita D.

The authors of a U.S. study have linked higher blood levels of vitamin D to lower rates of metabolic syndrome, as well as improved cholesterol and triglyceride profiles in the blood (Maki KC et al 2009).

What the study found: heart and diabetes risks
Researchers analyzed vitamin D blood levels in 257 men and women.

The participants’ intake of vitamin D from foods and supplements was estimated using diet questionnaires, and the results showed several things:
• Higher vitamin D blood levels showed 64 percent reduction in risk of metabolic syndrome.
• Higher vitamin D blood levels were associated with higher levels of HDL (“good”) cholesterol.
• Higher vitamin D blood levels were associated with lower triglyceride (blood fat) levels.
Higher vitamin D blood levels were associated with having a lower body mass index and smaller waist.

As the researchers noted, the cholesterol finding is important because every 1 mg/dL increase in HDL levels is associated with a five percent reduction in the risk of developing coronary heart disease (CHD).

In other words, if you exclude the influence of all other risk factors, a 10 ng/mL increase in vitamin D blood levels could decrease the risk of CHD by about 20 percent.

To help ensure optimal health, most vitamin D researchers recommend minimum blood levels ranging from 36 to 48 ng/mL (nanograms per milliliter), but three in four Americans fall well short of that mark.

The most recent survey of Americans’ blood levels pegged the average blood level in the U.S. at a subpar 24 ng/mL, while six percent had very unhealthy levels (i.e., lower than 10 ng/mL) and only 23 percent had healthy levels of 30 ng/mL or higher (Ginde AA et al. 2009).
