The Importance of Vitamin D3 for Your Immune System
Famously coined The Sunshine Vitamin, vitamin D has built quite a reputation for itself. This vitamin is one of the main nutrients we absorb from the bright rays of the Sun. When the skin is exposed to ultraviolet radiation, vitamin D is formed from a cholesterol derivative and absorbed into the circulatory system, where it begins to play its functional role in the body as Vitamin d3 (its active form). The Sun is a natural d3 supplement and is the primary way we intake this vitamin. After absorption, vitamin d3 is then transported to the liver for storage and deposits are found in the skin, brain, spleen, and bones. Although we do need to allow pure Sun exposure to absorb this vitamin, Sun safety practices should still be put in place. After about 5-10 minutes of Sun exposure, sunscreen that is a SPF15 or higher, should be applied for the duration of your time outdoors.
In this article we will be exploring this essential vitamin and its impact on our health.
Why is this vitamin so important?
Although vitamin D wears many hats in the body, its most important roles lie in its contribution to the strength of our immune system, skeletal system, and mood balance. Immune cells contain vitamin D receptors, which means they respond to vitamin d and utilize it to help create more immune fighting defenses in the body. Vitamin D also plays a role in preventing autoimmune disease, which studies have shown low levels being associated with disease like Multiple Sclerosis, Rheumatoid Arthritis and Lupus. Vitamin D is involved in the absorption of Calcium and the assimilation of Phosphorus, two key nutrients for bone formation. Without vitamin D, we could not maintain strong bones and teeth. It helps to regulate the amount of Calcium and Phosphorus in the blood.
Studies have found a link between low levels of vitamin D and depression. During the Winter months, a condition called S.A.D or Seasonal Affective Disorder becomes more predominant due to the lack of sunlight. Symptoms of S.A.D include depression, sadness, withdrawal, and a loss of “zest” for life. Vitamin D supplementation has shown promising results in individuals who suffer from depression and mood imbalance.
Wintertime, clouds, and smog reduce the body’s production of this sunshine vitamin. Deficiency can become more prevalent in people who live in cold, damp climates or in vegans, if conscious intake is not prioritized.
