Vitamin B complex, which includes a group of water-soluble vitamins such as B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin), plays a fundamental role in cellular energy metabolism. These vitamins act as coenzymes in various biochemical pathways that convert carbohydrates, fats, and proteins into usable energy (ATP) within the body. Deficiencies in certain B vitamins, particularly B12, B6, and B1, can lead to symptoms such as fatigue, weakness, and decreased mental performance, underscoring their importance in maintaining energy levels.

Clinical studies consistently show that correcting a deficiency in any B vitamin can alleviate fatigue and restore normal energy levels. For example, vitamin B12 supplementation is effective for individuals with pernicious anemia or low B12, and thiamine supplementation resolves fatigue associated with beriberi. However, evidence supporting the use of vitamin B supplements to boost energy in healthy, non-deficient individuals is limited and not robust. Randomized controlled trials have not shown consistent benefits of B vitamin supplementation for improving energy or reducing fatigue in the general population without deficiencies.

In summary, the use of vitamin B to treat or prevent energy deficiency is scientifically validated in cases of clinically diagnosed deficiency, but not as a general energy booster for healthy individuals. Thus, the evidence for its use is moderate (3/5), with strong support only in deficient populations.
