Why Vitamin D3 May Be the Best Fitness Supplement You’re Not Taking

In a time of shelters in place, social distancing, and all the other measures we are taking to stay at home and mitigate the spread of Covid-19, we might find ourselves deficient in important vitamins and minerals, with Vitamin D3 being no exception. Produced by the body’s own skin cells in response to sunlight, Vitamin D3 is an important vitamin to our overall health. 

Vitamin D3 is something of a passion of mine. When I am not passionately arguing for the benefits of squats and throwing out tips on how to squat, I also like to spend my time letting as many people as possible know about the power of this essential vitamin.  Strength Training and Vitamin D supplementation are what I credit with getting over anxiety and depression years ago.

Read on to learn about some of the health issues connected to a lack of Vitamin D3 and benefits of the vitamin, and ways to safely increase our intake in a time when we are all forced to stay inside more than usual.

How Vitamin D3 Benefits Our Health

  1. Aids in Weight Loss

Studies show Vitamin D3 can help you lose weight because it helps to burn body fat. This is not a replacement for good old fashioned diet and exercise, but if you seem to have hit a wall with dropping pounds, increasing your intake of this vitamin might be something to consider.

  1. Anti-Inflammatory

When the body has an adequate level of Vitamin D3, its natural inflammatory response is inhibited, which helps to reduce the risk of developing chronic inflammatory conditions. A sufficient amount of Vitamin D3 may also help in reducing the risk of diseases born out of inflammation in the body.

  1. Improves the Immune System/Fights Flu/Fights Cancer/Autoimmune Disorders

Vitamin D3 is significant to the function of immune cells. Deficiency in Vitamin D3 may lead to wounds healing more slowly, an increase in infections, or a greater chance in catching the flu. Though limited, there is research indicating some cancers like chronic lymphocytic leukemia and colorectal cancer are linked to a Vitamin D3 deficiency. A deficiency could be connected to autoimmune disorders such as lupus, Crohn’s, rheumatoid arthritis, etc. Therefore, an increase in Vitamin D3 might help your body to better fight off various illnesses and infections.



  1. Testosterone

This hormone, found in both men and women, is responsible for regulating fertility, muscle mass, fat distribution, and the production of red blood cells. Research indicates that low levels of Vitamin D3 is linked to lower testosterone levels, and therefore, supplementing might increase testosterone production

  1. Improves Mental Health

Research suggests that being deficient in Vitamin D3 could be related to several cognitive disorders such as depression, anxiety, Alzheimer’s, bipolar, and schizophrenia. For some with depression, a supplement might be an option in treating the disorder instead of prescription drugs, especially those with a diagnosed deficiency.

  1. Improves Calcium Absorption/Encourages Bone Strength

Vitamin D3 is known to help the body absorb calcium better and then disperse it to the bones. Vitamin D3 also helps the body to metabolize phosphorus, which is an important mineral to stronger and healthier bones.

  1. Relieves Muscle Cramps

Muscle issues like weakness, cramps, tingling, numbness, and twitching might be associated with low levels of Vitamin D3. By getting enough, we ensure we are keeping our muscles healthy.

  1. Improves Our Heart Health

Vitamin D3 is important for individuals with heart problems, because it helps in controlling inflammation around the heart and high blood pressure, improving overall cardiac function.

  1. Helps Control Insulin

An adequate intake of Vitamin D3 aids the body in controlling insulin levels and regulating glucose. Because of this, it can help in reducing the risk of diabetes, especially Type 2, and managing the condition in someone who is already diagnosed with diabetes.

  1. Cholesterol and Triglycerides

Research indicates that a deficiency in Vitamin D3 can raise levels of cholesterol and triglycerides. A sufficient amount of Vitamin D3 can help to keep these controlled, staving off other potential health problems.

Vitamin D3 is essential to total health. You can get your daily dose of Vitamin D3 in many forms such as sunlight, supplements, and foods like fatty fish, mushrooms, orange juice, egg yolks, Cod Liver Oil, cheese, and caviar. But, as always, check with your doctor first to see if you need, and could benefit from, additional Vitamin D3.
