Vitamin D’s Crucial Role in Cardiovascular Protection

Over the past several decades, several nutrients have gone through popularity phases. According to each study, the higher the dose of Vitamin D, the lower the risk of developing the disease. These findings support the concept of vitamin D possessing important pleiotropic actions outside of calcium homeostasis and bone metabolism. Research has yet to answer the questions that health professionals continue to ask: what processes can these nutrients affect in order to provide desired health outcomes, and how much of each nutrient is needed to produce results? Researchers from the University of Maryland and the U.S. In the T1DM patients, 32/179 (18 %) had an affected sibling; in 74/206 (36 %) cases, the parents were consanguineous while in 75/196 (38 %) cases even the grandparents were consanguineous (Table 1). The most common cause of cancer death in American men and women, lung cancer can be challenging to treat effectively.

The average participant was 41 years old with a body mass index (BMI) of 29.6 and 38% body fat. Insulin resistance is when your body does not respond normally to insulin secreted by your body, which can lead to high blood glucose levels. Frequency of vitamin D supplementation was recorded during the first year of life. New data, however, are suggesting a whole new panel of health effects previously unsuspected for this underappreciated vitamin. It may, in fact, be a crucial nutrient that plays a central role in coronary heart disease prevention. The overall prevalence of vitamin D deficiency among the 33,217 patients was 1.03%, which was lower than expected and probably reflects an underdiagnosis because of the hospital setting of the database. Ethnicity made a monumental difference.

The time needed to produce adequate vitamin D from the skin depends on the strength of the UVB rays (ie, place of residence), the length of time spent in the sun, and the amount of pigment in the skin. Humans are meant to obtain vitamin D through sunlight exposure. Vitamin D is not contained to any significant degree in food, nor was it meant to be obtained through oral intake. The researchers say that the findings of the study should be carefully interpreted. Investigators in the U.S. Add to this the sun phobia fostered by dermatologists advising us that sun exposure causes skin cancer, and most of us are terribly sun-deprived and thereby unable to activate vitamin D. Moreover, based on preliminary testing using external quality controls from Bio-Rad (Bio-Rad Laboratories Inc., Hercules, CA, USA) and DiaSorin, the within-run and between-run coefficients of variation for this assay varied from 3.2%–8.5% and 6.9%–12.7%, respectively.

It was clear, however, that vitamin D was a necessary ingredient for health, since children who failed to receive at least 300–400 IU per day, usually supplemented as cod liver oil, developed “bow legs,” or rickets, due to abnormal bone maturation in the legs. But the vitamin D dose recommended for adults was purely—and admittedly—fabrication. There was no association with diastolic blood pressure. In the 1960s, the only known consequence of vitamin D deficiency in adults was osteomalacia, a form of bone softening. The mean 25(OH) D level was 6.34 ± 1.47 ng/ml in the group with hypovitaminosis D and 39.27 ± 6.42 ng/ml in the group without it. The study sample included Saudi subjects recently diagnosed with DMT1 and those with established DMT1. And wearing clothing, sunglasses, and sunscreen to protect your skin from sun damage also blocks UV rays that promote vitamin D.

A study conducted during the winter months in Omaha, Nebraska, in healthy adult men showed that the participants utilized 3000–5000 international units of vitamin D per day to maintain a steady vitamin D blood level. The researchers concluded that the current RDA was inadequate to meet these requirements.8 Low government-issued vitamin D intake recommendations, along with deprivation of sunlight, has therefore resulted in a nation that is frightfully deficient in a crucial nutrient.
