Un nuevo estudio japonés ha relacionado las deficiencias de vitamina B12 y folato con un aumento de la fatiga y una menor motivación en adultos por lo demás sanos. La investigación examinó marcadores sanguíneos y síntomas autoinformados en cerca de 600 participantes.

Investigadores dirigidos por el profesor Hiroaki Kanouchi de la Universidad Metropolitana de Osaka analizaron los niveles sanguíneos de homocisteína, folato y vitamina B12. También evaluaron la fatiga utilizando la escala de fatiga de Chalder y una escala visual analógica, controlando factores como la edad, el sueño, la carga de trabajo y la dieta.

Study links major depression in young adults to altered cellular energy patterns in brain and blood

Researchers studying young adults with major depressive disorder have reported an unusual energy “signature” in both the brain and immune blood cells: higher ATP-related measures at rest, paired with a reduced ability to increase energy production when demand rises. The findings, published in Translational Psychiatry, may help explain common symptoms such as fatigue and low motivation, though the work is early and based on a small sample.

Study finds lower normal B12 levels tied to brain changes

A University of California San Francisco study has linked lower but still normal levels of active vitamin B12 to slower thinking and white matter damage in healthy older adults. The research, published in Annals of Neurology in 2025, suggests current guidelines may miss early neurological risks. Researchers examined 231 participants with an average age of 71.

Researchers question vitamin B12 levels and cancer links

Scientists are raising new questions about the relationship between vitamin B12 and cancer risk. While deficiency has long been known to increase dangers, recent studies suggest very high levels may also play a role.

Study links daily mental sharpness to productivity gains

Researchers at the University of Toronto Scarborough have found that feeling mentally sharp on a given day can boost productivity by up to 40 minutes. The study, published in Science Advances, tracked university students over 12 weeks and connected clearer thinking to setting and achieving bigger goals. Factors like sleep and workload influence these daily fluctuations.

UCSF study links iron-associated protein FTL1 to age-related memory decline in mice

5 de abril de 2026 Reportado por IA Verificado por hechos

Researchers at the University of California, San Francisco report that higher levels of the iron-associated protein FTL1 in the hippocampus of older mice are tied to weaker neural connections and worse performance on cognitive tests. In the experiments, reducing FTL1 in older mice was associated with increased neuronal connectivity and improved memory performance, findings published in Nature Aging.

Large VIVID trial finds high-dose vitamin D3 did not lessen acute COVID-19 severity, but adherence analysis suggests possible long COVID signal

A major randomized trial led by Mass General Brigham found that a four-week course of high-dose vitamin D3 started soon after a positive COVID-19 test did not reduce acute illness severity, healthcare visits or deaths, and did not curb household spread. But in an analysis limited to participants who consistently took the assigned pills, researchers observed a small, borderline statistically significant difference in lingering symptoms reported eight weeks after infection, a finding they say warrants further study.

Teenagers and young adults who reported using pre-workout dietary supplements were more than twice as likely as non-users to say they slept five hours or less per night, according to an analysis of Canadian survey data published in the journal Sleep Epidemiology.
