Calms Your Blood Pressure
According to Machemehl-Helmly, vitamin D3 plays a role in modulating the system that controls blood pressure. However, this isnt set in stone. The Mayo Clinic says that vitamin D deficiencymay be linked to heart disease and an increased risk of high blood pressure . At the same time, more research is needed. Its too early to say whether a lack of vitamin D causes high blood pressure, or whether vitamin D supplements may have any role in the treatment of high blood pressure, the Mayo Clinic notes.
Protect Against Respiratory Infections
Increase your level of vitamin D if youre deficient, and you may find that you get fewer respiratory infections than usual.
One review of 25 randomized controlled trials involving about 11,300 people suggests that participants who were vitamin D deficient saw a 12 percent reduced risk for respiratory infections after taking a vitamin D supplement, though not every study saw a clear benefit from supplementation. Researchers published their findings in February 2017 in BMJ.
The main limitations? Researchers werent sure whether participants had received a flu vaccine or were diagnosed with the respiratory ailment chronic obstructive pulmonary disease , which are two confounding factors that may have skewed the results.
An accompanying editorial cautions readers to take the findings with a grain of salt, and the authors argue against standard year-round vitamin D supplementation and call for additional research.
What You Can Do Now
If youre concerned about vitamin D deficiency, ask your doctor to check your vitamin D level, says Dr. Deal. If the level is low and your provider starts you on supplements, you need repeat testing in eight to 12 weeks to make sure the level is not too high or too low.
If testing shows your vitamin D level is normal, you need repeat testing every two to three years unless you have major changes in your overall health.
Different diseases need different doses of vitamin D. If you have chronic kidney disease or parathyroid disease, ask your kidney specialist or endocrinologist about the type and dose of vitamin D you need.
If youre pregnant or breastfeeding, Dr. Deal recommends you keep taking vitamin D supplements as long as your doctor prescribes them. The supplement is linked to healthy development for you and your baby.
For bone health, be sure to stay active and remember to eat a calcium-rich diet. Consult with your doctor frequently to make sure youre taking the right steps to current bone health.

The term vitamin D is kind of a misnomer because you will not find anything labeled simply as vitamin D in a pharmacy vitamin aisle. Rather, your choices will be vitamin D2 or vitamin D3 . Generally, when one mentions vitamin D, the implied selection is vitamin D2. For the purpose of this article, when vitamin D is mentioned, it will refer to vitamin D2. The names can be confusing, because many times, patients go into the pharmacy looking for vitamin D and are surprised that there is a D2 and a D3.
Vitamin D comes from plant sources, such as wild mushrooms, as well as fortified foods, such as milk or cereal products. Its strength is typically measured in international units, which is abbreviated as IU on labeling. The 50,000 IU capsules are prescription only, while lower strengths are available over-the-counter. Vitamin D is less expensive to produce and therefore is the form most commonly found in fortified food products.
Vitamin D3 mainly comes from animal sources such as fish oil, fatty fish, liver, and egg yolks. When your skin is exposed to sunlight, it produces vitamin D3. For this reason, it is sometimes referred to as the sunshine vitamin. Its strength is also measured in international units. All forms of vitamin D3 are available over-the-counter.

Top 5 Benefits Of Vitamin D
Vitamin D is an often-overlooked, under-consumed nutrient that plays a major role in your overall health and performance in the gym. Learn how to make sure you’re getting enough so you can be on top of your game!
You probably know it as the “sunshine vitamin,” or the vitamin that helps maintain strong bones, but there’s a lot more to Vitamin D than meets the eye. It serves a variety of functions in the body, including maintaining optimal bone and muscle health, as well as having favorable effects on inflammation. Unfortunately, most of us don’t get enough vitamin D on a daily basis, with a reported one billion people worldwide having a deficiency.
While your training regimen and supplement stack may be on point, missing out on this oh-so-important nutrient can wreak havoc on overall health, as well as reduce performance in the gym. So it’s about time we give this nutrient the attention it deserves. Pour yourself a glass of milk and read up on the latest findings on how vitamin D can optimize your health.
The Basics Of Vitamin D
Vitamin D is a unique type of vitamin because it actually acts more like a steroid hormone than a dietary aid and is not readily available in most foods like other vitamins often are because of this, its estimated that nearly 75 percent of people have some kind of deficiency.
Rather, vitamin D is sourced primarily from the sun, which is why its often referred to as the sunshine vitamin. When the skin absorbs sunlight, it synthesizes the UVB rays into vitamin D.
Though you should always limit long exposure to the sun, getting adequate amounts of rays is the first step in ensuring your body has good stores, which is important since vitamin D has a tremendous effect on mood and, over time, can help to ease symptoms of depression. Its also a type of fat-soluble vitamin that plays a major role in the way the body absorbs other nutrients.
But not everywhere in the world is as sunny as California or Florida, which limits access, and because the synthesization process varies from person to person, not everyone has the same capability to intake the proper amounts needed for optimal well-being. This is where supplements come into play.

Is Vitamin D3 Better Than Vitamin D2
Studies show that Vitamin D3 is far more important for our health than Vitamin D2. So either choose a Vitamin D3 supplement, or one which contains optimal levels of both forms. Vitamin D2 on its own is not enough.
Experts used to think that vitamins D2 and D3 were of equal importance for human health. But this was based on outdated studies of rickets in children. These days, we know lots more about Vitamin D. And it is clear that D3 is far more important and more effective for our health and wellbeing.
We need to look at how the body absorbs Vitamin D to understand why Vitamin D3 is more important. There are lots of biological processes involved. A specific enzyme in the liver helps Vitamin D3 metabolise into the bioactive form of Vitamin D. This process takes much longer with Vitamin D2.
Help Prevent Cognitive Decline And Dementia
Foroutan points out that there are vitamin D receptors in brain tissue, which suggests that the vitamin may play a role in cognitive function and, potentially, the risk of dementia. Research may support this notion, with one article suggesting that vitamin D may help clear up amyloid plaque, the hallmark of Alzheimers disease . The authors note that more research is needed to confirm a cause-and-effect relationship between an adequate level of vitamin D and the neurodegenerative disorder.
Meanwhile, a large review published in July 2018 in Nutritional Neuroscience found insufficient evidence that vitamin D supplements protect against neurodegenerative diseases such as Alzheimers and Parkinsons disease. Researchers wrote that they also couldnt confirm that vitamin D synthesized from sun exposure helps to protect against neurodegenerative diseases.

A Stronger Immune System
The human bodys immune system plays an important part in its ability to fight off viruses and disease-causing bacteria, as well as infections. When the immune system is weak, a person is more likely to become sick and develop the disease. A stronger immune system, however, helps to prevent the frequent occurrence of illness. A review paper published by the Feinstein Institute for Medical Research explains that the cells of the immune system contains vitamin D receptors. The particular cells that contain these receptors include antigen-presenting cells, T cells, and B cells. This means that vitamin D is able to assist with the action of the immune system and, according to the review paper, may also help to reduce the risk of obtaining an infection.
