Here Are the 9 Vital Functions of Vitamin D for Your Health

Vitamin D, which is technically a hormone rather than a vitamin, is a crucial nutrient. Unfortunately, many Americans – even those who eat a good diet – are deficient in vitamin D.¹ Though definitions of vitamin D deficiency can vary, experts agree that it has nearly reached epidemic status. Analysis of the ongoing national survey data from the US Centers for Disease Control indicates that a majority of Americans may not be getting sufficient vitamin D. One way to get a natural vitamin D boost is from exposure to sunlight. But since we're wearing more sunscreen while outside and spending more time inside, our levels of vitamin D have fallen in recent decades. Why does that matter? Some research has linked vitamin D deficiency to serious, long-term health issues.² Those who think of vitamin D only as the “sunshine vitamin” may fail to fully understand the significant ways vitamin D affects their brain, body and overall health.³ Let's take a closer look at how vitamin D works in key areas of the brain and body, as well as how to increase levels of this essential vitamin...naturally! Here Are 9 Vital Functions of Vitamin D Immunity Vitamin D receptors are found all over the body, including the immune cells. Research has clearly shown that vitamin D deficiency is part of the seasonal nature of cold and flu outbreaks⁴ – less sunlight means less vitamin D, which can lead to lower immunity and more illness. Bones It’s well-documented that vitamin D is essential for the proper absorption of calcium, and it’s been shown to greatly reduce fracture risk in two ways. First, it helps with the formation of stronger bones; second, vitamin D helps improve balance and prevent falls by enhancing muscle contraction.⁵ Muscles One of the byproducts of vitamin D’s breakdown, called 1,25(OH)2D, enters muscle cells and affects the nucleus. Once there, the vitamin D metabolite enhances the cell’s contraction ability. Since muscles work by contraction and relaxation, a muscle’s ability to contract is essential to its strength and response to outside forces. As such, vitamin D helps make muscles stronger in a very direct way. Lungs As many studies indicate, vitamin D plays a role in keeping our lungs healthy due to vitamin D possessing a range of anti-inflammatory properties – with greater concentrations of vitamin D resulting in greater lung health benefits.⁶ Heart Research has demonstrated an inverse relationship between vitamin D levels in the blood and high blood pressure (HBP or hypertension). In other words, the lower the vitamin D, the higher the blood pressure. The excess strain and resulting damage from high blood pressure can cause the coronary arteries serving the heart to slowly narrow and harden, greatly increasing the risk of a heart attack. Kidneys Because vitamin D is a fat-soluble vitamin, it helps to regulate kidney function and plays a very beneficial role in treating serious kidney issues.⁷ Mood When it comes to being happy, the scientific evidence is clear. The lower your vitamin D levels, the more likely you are to feel blue rather than happy. Vitamin D deficiency has long been associated with higher incidences of low mood. Interestingly, in a 2014 study, the positive effect of vitamin D3 on mood was comparable to the effects of the anti-depressants.⁸ Weight Loss When you don’t have enough vitamin D, you can feel hungry all the time, no matter how much you eat. That's because low levels of vitamin D can interfere with the effectiveness of leptin, the appetite hormone that tells you when you're full. When vitamin D is replenished and back to normal levels, leptin’s actions are restored, thus creating feelings of satiety and aiding in weight loss. Cognitive Function In the past few years, many studies have linked shortage of vitamin D with cognitive issues in older men and women. Research has demonstrated that vitamin D has a variety of neuroprotective roles, including helping to rid the brain of beta-amyloid, an abnormal protein that is believed to be a major cause of severe memory issues.⁹ Other studies have shown that seniors with very low levels of vitamin D are at an increased risk of serious, long-term memory issues. Recommended Daily Vitamin D In the US, the current recommended daily dose of vitamin D is 600 IU. However, most experts agree that this is well below the physiological needs of most individuals. Some experts have suggested that all adults should take at least 2000 IU of vitamin D daily, but for many people, this daily dose doesn’t raise their vitamin D levels into a healthy range.
