REPORTS SUGGEST DEFICIENCY MAY CONTRIBUTE TO TIREDNESS; SPECIALISTS STRESS INDIVIDUAL VARIATION AND THE NEED FOR MEDICAL GUIDANCE
A report from La Nación highlights expert opinions suggesting that Vitamin B12 may help reduce fatigue and support sleep quality in people with deficiencies or low energy levels.
Health experts interviewed by La Nación say Vitamin B12 may play a meaningful role in reducing chronic fatigue and supporting deeper, more restorative sleep — especially in individuals whose tiredness stems from nutritional deficiencies. The vitamin is essential for energy metabolism, red blood cell production and neurological function.
According to specialists, inadequate B12 levels can contribute to persistent exhaustion, poor concentration, mood fluctuations and irregular sleep cycles. Research cited in the report notes that supplementation — when medically appropriate — may help restore normal energy patterns and regulate circadian rhythms in some individuals.
Doctors emphasize that Vitamin B12 is not a cure-all and should not be used as a universal remedy for fatigue. Many factors can cause chronic tiredness, including stress, anemia, hormonal conditions, sleep disorders and mental health issues. Determining B12’s relevance typically requires laboratory testing and professional evaluation.
The report highlights that B12 is naturally found in foods such as meat, eggs, dairy, fish and fortified plant-based alternatives. Specialists note that people following vegan diets or those with absorption issues may be at higher risk of deficiency.
Sleep researchers cited in the article say that patients with low B12 levels occasionally report improvements in sleep stability and nighttime alertness after restoring normal levels, though evidence remains mixed and varies across clinical studies.
Health experts recommend that individuals experiencing severe or persistent fatigue consult physicians before using supplements, as improper dosing or self-treatment can mask underlying medical conditions.
