The Link Between Vitamin D3 and the Immune System

As we age, our immune function declines. This shift can make us more prone to developing chronic illnesses and diseases overtime. However, while a weakening immune system is a natural effect of aging, there are natural ways we can give our immune systems a much needed boost. Does vitamin D help? Vitamin D, especially D3, does a fantastic job at supporting the immune system. Because it plays a critical role in fighting off illness, getting enough vitamin D throughout the day might be the secret to a happy and healthy immune system.

Is vitamin D3 the key to a healthy immune system at any age? This article covers the link between vitamin D3 and the immune system, as well as how to increase your vitamin D intake throughout your day.

What Is Vitamin D3?

Vitamin D3 is a fat-soluble nutrient that plays a critical role in many of the body’s functions.

It helps the body with calcium absorption, which is essential for maintaining bone health. Together, vitamin D and calcium work to protect the bones from age-related bone loss or weakening. More specifically, vitamin D3 can help prevent osteoporosis, a disease common in older adults that weakens the bones and makes them more prone to breaking. [1]

Vitamin D3 also has an array of longevity benefits. It slows the development of fine lines, encourages cellular repair, and supports immune function, which we’ll get into in the next section.

Does vitamin D help the immune system?

So we know that Vitamin D3 helps keep the bones healthy and supports cellular repair. But how does vitamin D3 help immune system functioning? As we age, our immune system’s ability to fight off disease declines. This is why older adults are more prone to developing chronic illnesses and diseases.

Vitamin D plays an essential role in fighting off illness. By getting your recommended daily intake, you can help support your immune system and improve its ability to fight off illness.
