What exactly does vitamin D do?
Research shows that this “sunshine vitamin” affects not only your bones and skeletal structure, but also immune function, blood pressure, mood, brain function, and your body’s overall ability to protect against a range of diseases.
According to a 2019 review, the benefits of vitamin D are thought to include support for bone health and immunity, resistance to chronic conditions such as heart disease, cancer, diabetes and depression, and infections and viruses.
It is estimated that 95 percent of most people’s vitamin D comes from daily exposure to sunlight. However, since many people today do not spend time in the sun every day or regularly consume foods that provide enough vitamin D (which is difficult to do), most adults – and children too, even infants and breastfed babies – are now encouraged. supplementing with vitamin D.
What are the benefits of taking vitamin D? Here are some ways that maintaining adequate vitamin D levels can support overall health:
Contributes to Bone Health.
Vitamin D plays a role in the absorption of calcium into the bones. Calcitriol (converted vitamin D) works with parathyroid hormone to maintain calcium levels.
Supports Immune System.
Exposure to UV light causes changes in the human body, including an increase in vitamin D levels. Our immune cells contain receptors for vitamin D, and vitamin D has been shown to benefit overall immune function in a variety of ways, including preventing prolonged or excessive inflammatory responses.
Helps Manage Blood Sugar Levels and May Prevent Diabetes.
Diabetes symptoms result from insulin deficiency or inadequate insulin secretion following increases in insulin resistance. According to research conducted at the London School of Medicine and Dentistry, calcium is required for insulin secretion, and the benefits of vitamin D contribute to the regulation of insulin secretion by promoting calcium absorption and utilization.
May Help Protect Against Cancer
Vitamin D plays a role in factors affecting tumor growth, cell differentiation and apoptosis. Vitamin D deficiency symptoms have been associated with increased risks for developing cancer, particularly breast, colon, and prostate cancers.
Facilitates Hormone Regulation and May Help Improve Your Mood
Because it acts like a hormone in our body and affects brain function, vitamin D deficiency has been associated with an increased risk for mood disorders, including depression, seasonal affective disorder, and severe mood problems experienced during PMS, insomnia, and anxiety.
Low levels can also interfere with proper testosterone and estrogen production, leading to imbalances that can result in many unwanted symptoms.
Supports Skin Health
Why is vitamin D good for your skin? Some of the ways vitamin D benefits the skin include supporting your immune system, controlling inflammation, and aiding skin cell growth, repair, and metabolism.
Adequate levels can help prevent skin aging and reduce redness, dryness, and other symptoms caused by eczema and psoriasis.
