Does Body Weight Affect the Benefits of Vitamin D?

A new study conducted by Brigham and Women’s Hospital finds that body weight can substantially affect the absorption of vitamin D. It examines the impact of body mass index (BMI) on the metabolization of vitamin D. The result shows that vitamin D is most effective in people with a healthy weight.

Due to the fat-soluble nature of vitamin D, individuals with higher body fat percentages may “isolate” the vitamin in their fat cells. This process affects the amount of vitamin D circulating in the blood and its expected level of effectiveness. For this reason, people with obesity may require higher quantities of vitamin D to get its benefits.

Listed below are some benefits of vitamin D for the body and why optimizing metabolization is a good idea.

Vitamin D Boosts Immune System

Vitamin D helps the immune system combat viruses and bacteria. It can stimulate killer T cells, which is pivotal in fighting disease. On the other hand, vitamin D deficiency is often associated with a higher risk of infections, such as influenza, upper respiratory tract infections, and tuberculosis.

Vitamin D Reduces Inflammation

This vitamin has potent anti-inflammatory benefits. Research shows that vitamin D promotes the production of an anti-inflammatory cytokine called IL-10 while inhibiting proinflammatory cytokines. Another study also shows how vitamin D can help reduce the risk of inflammation during Covid-19 infection.

Vitamin D Promotes Healthy Bones

Vitamin D plays an important role in maintaining bone health. It promotes the absorption of calcium, which is essential for strong bones and for preventing osteoporosis. A lack of vitamin D can lead to rickets in children and osteomalacia in adults.
