Vitamin D3

A strong immune system support and hormones regulator


Vitamin D3

Vitamin D3 is essential in supporting the immune system and in regulating your hormones. This supplement is ideal for those working in offices or to those who are otherwise deficient in getting enough Vitamin D from natural sources.

But just how important is Vitamin D and should you be concerned that you are getting enough? Research suggests that Vitamin D may play a pivotal role in fighting chronic diseases. According to the National Institutes of Health (NIH), low levels of Vitamin D are linked with an increased risk of Multiple Sclerosis (MS) which is a chronic condition involving your Central Nervous System (CNS) where your immune system attacks myelin, which is the protective layer around nerve fibers.

Research also suggests that:

  • Vitamin D reduces your risk of Heart Disease. Heart diseases such as Hypertension, Heart Failure, and Stroke are linked with low levels of Vitamin D.
  • The chance of contracting severe illnesses are reduced with maintaining the proper levels of Vitamin D. While studies are mixed on Vitamin D minimizing the severity of infection once afflicted with COVID-19, recent reviews by NIH and BioMedCentral (BMC) found that low Vitamin D levels contribute to Acute Respiratory Distress Syndrome which has been seen in large numbers of the infected.
  • Those failing to maintain optimal levels of Vitamin D are at increased risk of infections and Autoimmune Diseases, such as Rheumatoid Arthritis, Type 1 Diabetes, and Inflammatory Bowel Disease.

In addition to physical symptoms, Vitamin D3 plays an important role in regulating mood and reducing depression. A recent study on the effect of vitamin D supplement on negative emotions found that those who had been experiencing negative emotions, and then received vitamin D supplements, noticed an improvement in symptoms. Low levels of Vitamin D is also a risk factor for more severe fibromyalgia symptoms, anxiety, and depression.
