Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Vitamin B12 is often promoted for increasing energy and combating fatigue. Scientifically, vitamin B12 is essential for the normal functioning of the brain and nervous system and for the formation of red blood cells. Deficiency in vitamin B12 can lead to megaloblastic anemia, which is associated with symptoms such as fatigue, weakness, and low energy. In individuals with a diagnosed B12 deficiency, supplementation is highly effective at restoring normal energy levels and alleviating fatigue. Numerous clinical studies and reviews support the use of vitamin B12 for treating fatigue in deficient populations, such as older adults, individuals with malabsorption disorders, vegans, or those with pernicious anemia. However, for people with normal B12 levels, there is little evidence to suggest that additional B12 supplementation enhances energy or reduces fatigue. Double-blind, placebo-controlled trials in healthy individuals have not found significant improvements in energy or reduction in tiredness with B12 supplementation. Therefore, while there is strong scientific evidence for the use of vitamin B12 to treat fatigue due to deficiency, its use in otherwise healthy, non-deficient individuals is not supported by robust evidence. The overall rating of 3 reflects strong validation for deficiency states but limited evidence for use in the general population for boosting energy.
