The Claim
Many people believe that taking vitamin B12 supplements can provide an instant energy boost, similar to caffeine. This view is particularly popular among individuals experiencing fatigue.
Origin
This myth likely stems from marketing strategies and anecdotal reports that suggest quick energy increases, as well as the role of B12 in energy metabolism.
What Science Says
Research indicates that vitamin B12 is essential for energy production at the cellular level, but its immediate effect on energy levels is not supported by clinical evidence. Randomized controlled trials (RCTs) show that B12 supplementation primarily benefits those with a deficiency, where it can alleviate fatigue over time. It does not act as a stimulant that provides immediate energy.
Verdict
Misleading
