How Vitamin D Supports Immunity

on May 25, 2020

Vitamin D & How it Works

Vitamin D is an important compound for mediating multiple biochemical reactions in the body. What’s interesting about vitamin D is that it acts more like a hormone.

In fact, all of our cells have vitamin D receptors, which is not the case for other molecules.

The process of producing vitamin D is fascinating and involves multi-step physiology that starts at the level of the skin.

Step 1 –  when the body synthesizes cholesterol, it will get converted at the skin level by a chemical reaction that involves sunlight exposure (i.e., photons).

Step 2 –  once the cholesterol is transformed into the inactive form of vitamin D, the liver will produce a special enzyme that catalyzes a second metabolic reaction.

Step 3 –  finally, the kidneys release an enzyme to produce the active form of vitamin D, which is known as 1,25-dihydroxycholecalciferol.

 

The health benefits of vitamin D

  • Increases bone mineral density
Bone mineral density gradually decreases as we age. This process is physiological, and it’s exacerbated by a sedentary lifestyle, poor dietary choices, and vitamin D deficiency.
Low bone mineral density can lead to a condition known as osteoporosis, which is characterized by fragile bones and frequent fractures.
Fortunately, vitamin D supplements improve calcium and phosphate metabolism to optimize bone mineralization and decrease the risk of osteoporosis.

 

  • Facilitates hormonal regulation
Many hormones interact with each other via a common feedback loop, including insulin, growth hormones, and vitamin D.
    • Post-menopausal symptoms
    • Calcium metabolism
    • Blood sugar levels.

 

  • Optimizes the function of the immune system
Vitamin D is a crucial compound for the regular function of the immune system, as it exerts anti-inflammatory and immunomodulating properties that keep immune reactions in check.
Additionally, vitamin D proved to be a booster of T-cell and macrophage activity to efficiently eradicate any foreign pathogens.
In a 2011 paper, scientists analyzed the effectiveness of vitamin D on the immune system and found that low levels of this compound in the bloodstream increases the risk of infections and immune-related maladies.
The lungs are the most susceptible organs to vitamin D deficiency in terms of immune function. You see, when researchers observed the effects of low vitamin D serum levels, they found that patients had a higher risk of developing asthma, chronic obstructive pulmonary disease (COPD), and respiratory infections.

 

These findings suggest that vitamin D plays a major role in the innate and specific immune system.

 

Summary

Vitamin D offers a myriad of health benefits for the body that should not be taken for granted. Unfortunately, many people suffer from vitamin D deficiency without even realizing it, which leads to several health problems with unknown origins.

The most effective method to reverse and/or prevent vitamin D deficiency is by integrating dietary supplements into your daily routine.

We, at Nature-Leaf, offer the highest quality vitamin D mixed with other immune-boosting substances to make the most effective immunomodulating supplement in the market.
