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. It is known that various cells of the immune system, such as t lymphocytes and antigen presenting cells, express the vitamin d receptor on their surface when activated. Recently, it has been found that treatment of these immune cells with vitamin d influences their expression of cytokines, which are chemical messengers of the immune system. The immune modulating effects of vitamin d extend to monocytes and dendritic cells of the immune system as well. Dendritic cells are important antigen-processing cells of the immune system that function to initiate the immune response. Vitamin d may prevent overactivity of the immune response and keep the immune system in a normal healthy state of vigilance.vitamin d supports optimal cardiovascular function. Research has uncovered the role vitamin d plays in supporting cardiac function. Heart myocytes (cells) express the vitamin d receptor, as do smooth muscle cells of blood vessels. The benefits of vitamin d on the heart are potentially far-reaching. Studies on mice heart cells have shown that vitamin d administration impacts their growth and proliferation. In these cells, vitamin d inhibited the release of a protein that could be detrimental to the function of these cells, displaying cardioprotective properties. It has also been shown that vitamin d has a modulatory effect on heart rhythm. Review: Solid Value for a High-Potency Vitamin D3 — Easy to Take, Long-Lasting Supply - I’ve been taking Doctor’s Best 5,000 IU Vitamin D3 for a while now, and it’s one of the easiest supplements to work into my routine. The capsules are very small, smooth, and easy to swallow — no gritty texture or lingering taste. I like that it’s made with extra virgin olive oil, since D3 is fat-soluble and this may help with absorption without needing to plan it around a heavy meal. Vitamin D3, when taken as recommended by a healthcare provider, can support bone health, help maintain healthy teeth, aid immune function, and contribute to overall well-being — especially if you’re not getting enough from sunlight or diet alone. The 360-count bottle is a real convenience — I don’t have to think about restocking for nearly a year, and the cost per capsule works out to be very reasonable. I haven’t noticed any stomach upset, aftertaste, or other side effects, and I appreciate the simplicity of the formula without unnecessary fillers. A couple of things I personally keep in mind: 5,000 IU is a high dose, so I take it under my doctor’s guidance and get my levels checked to make sure they stay in a healthy range. I store the bottle in a cool, dry spot away from sunlight, because I know softgels can sometimes stick together if exposed to heat. For me, taking it with food feels like the best way to support absorption and avoid any chance of mild GI discomfort. Bottom line: This is a simple, well-formulated, high-strength D3 that’s easy to take and lasts a long time. As long as you’re mindful of the dosage and store it properly, it’s a great value and a reliable way to keep your vitamin D where it should be. Review: Doctors Best ! - Good value. Easy to swallow.
