Vitamin D, often referred to as the "sunshine vitamin," plays a vital role in maintaining bone health and supporting immune function. While its direct link to boosting energy isn't firmly established, Vitamin D deficiency can lead to fatigue and low energy levels. This is because Vitamin D influences muscle function and mood, both critical to maintaining vitality. For those deficient, supplementation may restore balance, helping to alleviate fatigue, although results can vary depending on individual health conditions.

While Vitamin D may not be a miracle solution for energy, maintaining adequate levels is essential for overall well-being. Experts advise getting Vitamin D from a mix of sunlight exposure, diet, and supplements where necessary, particularly during the winter months or for those with limited sun exposure.
