Importance of Vitamin D in Managing Your Immunity

1

Vitamin D Deficiency (VDD) is a major health problem in both the developed and developing countries across the globe. In India, despite ample sunlight (required for the synthesis of vitamin D within the body), VDD prevalence has been documented to be in the range of 50-90% among all the age groups.

Importance of Vitamin D

Vitamin D plays several critical roles in your body & has long been known to help the body absorb and retain calcium and phosphorus; both critical for building bones.

Some research also shows that having healthy levels of Vitamin D, as well as taking a Vitamin D supplement, can help keep your immune system healthy and may protect against respiratory illnesses in general.

Vitamin D is necessary for the proper functioning of your immune system, which is your body’s first line of defense against infection and disease.

This vitamin plays a critical role in promoting immune response. It has both anti-inflammatory and immunoregulatory properties and is crucial for the activation of immune system defenses1.

In fact, the vitamin is so important for immune function that low levels of vitamin D have been associated with an increased susceptibility to infection, disease, and immune-related disorders2.

In conclusion, ensuring healthy Vitamin D levels can maintains immune health. Plus, Vitamin D supplements may protect against respiratory infections in general.3

Few foods naturally contain Vitamin D, though some foods are fortified with the vitamin. For most people, the best way to get enough vitamin D is taking a supplement because it is hard to eat enough through food.

Vitamin D production in the skin is the primary natural source of vitamin D, but many people have insufficient levels because they have limited sun exposure due to being inside much of the time. Also, people with darker skin tend to have lower blood levels of vitamin D because the pigment (melanin) acts like a shade, reducing production of vitamin D.

There are many brands of Vitamin D in different formats available in the market – Sachets, Soft Gels and Nano Preparations. The Nano Vitamin D format is proven to be the superior format since it ensures greater absorption of Vitamin D in the body.
