Doctors Best Vitamin D3 (cholecalciferol) is a nutrient that is critical to many bodily functions. Doctor's Best Best Vitamin D3 is beneficial for supporting bone health, immune wellness, cardio- vascular function, and cellular metabolism, among others. Mounting research is highlighting the ever-increasing benefits of optimal vitamin D3 status. Vitamin D3 is known to interact with over 200 different genes and thus plays a crucial regulatory role as a metabolic activator for a multitude of metabolic processes.
Vitamin D from dietary intake or sun exposure requires two activation steps in the body. The first activation occurs in the liver, while the second activation occurs in the kidneys, allowing for regulation of calcium metabolism. However, vitamin D receptors are present throughout the body, in tissue such as the skin, cartilage, heart, prostate, bones and intestines. Thus, the second activation step also takes place in local tissues. Recent discoveries have highlighted the important modulatory effects of vitamin D on various cells of the immune system. Vitamin D enhances and regulates immune function Vitamin D supports optimal cardiovascular function Studies in humans have confirmed the importance of vitamin D for heart function. In a study consisting of 1,739 participants from the Framingham Offspring Study, those individuals with the highest levels of vitamin D had superior cardiac function in relation to those with low vitamin D levels. These results make sense when taken in context of the overall effects of low vitamin D. These effects include an imbalance in the immune production of inflammatory markers, disturbing the normal inflammatory response and leading to potential effects on all tissues, including the heart and blood vessels. Restoration of optimal vitamin D status supports a healthy, normal inflammatory response and may thus restore the optimal health of the heart and cardiovascular system. Furthermore, recent research highlights the profound benefits of vitamin D sufficiency in the realm of markers of cardiovascular wellness. Studies have previously shown that vitamin D supplementation has no effect on weight loss. However a recent study conducted in 200 healthy overweight individuals has shown that vitamin D supplementation can enhance the cardiovascular benefits associated with weight loss. The individuals participating in a 12-month weight reduction program were divided into two groups – one received placebo while the other group received supplemental vitamin D on a daily basis. At the end of the study, it was found that neither placebo nor vitamin D had a measurable effect on weight loss, as both groups lost similar amounts of weight. However, cardiovascular markers and blood lipid markers significantly improved in the vitamin D group, indicating enhanced cardiovascular support with vitamin D supplementation. A further way in which vitamin D may influence the health of the cardiovascular system is through its potential blood pressure regulatory effect. While the mechanism of vitamin D’s effect on blood pressure regulation is unclear, it is known that vitamin D regulates calcium balance, supports endothelial function, activates gene transcription, and influences the sodium-potassium balance and aldosterone system in the kidneys. It is likely that vitamin D exerts its blood pressure regulatory effect in one or more of these ways. A study was conducted to assess the effects of vitamin D status on blood pressure. In this study, data from the Third US National Health and Nutrition Examination Survey was used to determine the association of blood pressure levels with vitamin D status in healthy individuals. The results of this study, which included data from 12,644 people, showed that those individuals with the highest vitamin D status had an increased ability to maintain their blood pressure levels in the normal range. By supporting blood pressure levels within a range that is already normal, vitamin D promotes the health and wellness of the cardiovascular system. Vitamin D supports healthy bone density and structure An interesting study was performed recently in Finland in which 212 adolescent females were divided into three groups – a placebo group receiving no vitamin D, a low-dose vitamin D group (200 IU per day) and a higher dose vitamin D group (400 IU per day). The study aimed to measure the effects of vitamin D intake on bone mineral density in these young healthy females who also had adequate calcium status. At the end of the one year study, both vitamin D groups had significant improvements in bone density measured at the femur bone, whereas the 400 IU group also had significantly higher mineral density at the lumbar spine. These findings indicate the importance of vitamin D in bone structure and formation and also indicate the role of vitamin D in bone health independent of calcium intake.
