Tired all the time? What to know about B12 and if it actually boosts energy levels
Med spas are raving about vitamin B12 shots as a pick-me-up. But do they actually make you feel more energized? If you spend time on social media, you may have seen med spa owners and employees describing vitamin B12 shots as a pick-me-up . When they’re run down or facing a busy week, they say, a quick injection gets them through. Some med spas say many people feel an energy lift within a day or…
Vitamin B12 is an essential nutrient found in animal products and fortified foods. It plays a key role in producing red blood cells, DNA, and nerve function, and helps convert food into energy. However, not everyone needs extra B12, as most people already have sufficient levels.
Deficiency can cause fatigue, memory issues, depression, and numbness in hands and feet. Common causes of low B12 include poor stomach acid production, pernicious anemia, surgeries, digestive disorders, and certain medications. Vegans and vegetarians may also be at risk unless they consume fortified foods or supplements.
For those experiencing fatigue due to B12 deficiency, treating the deficiency can boost energy levels. However, if levels are already adequate, additional B12 is unlikely to provide benefits. The placebo effect may contribute to feeling more energetic after a shot. Med spas profit from selling these shots, but B12 is safe at high doses.
Fatigue has various causes, so consulting a healthcare provider is crucial. A simple blood test can measure B12 levels, but interpreting results can be challenging. Levels below 400 pg/mL are generally considered deficient. Treating deficiency depends on the underlying cause, which may involve lifestyle changes, medication adjustments, or addressing digestive disorders. For severe cases, B12 shots are recommended. Oral supplements are effective for most people.
