Cornell University research adds a new twist to healthy aging: low vitamin B12 may damage skeletal muscle mitochondria, reducing energy production and cellular resilience. The study found suboptimal B12 levels are common among older adults, and B12 supplementation improved mitochondrial function in aged mice. Human trials are now needed to confirm whether correcting deficiency can slow aspects of age-related decline.
Researchers report a new way to make vitamin B12 by using controlled light to grow Spirulina, a blue green algae. The approach produces biologically active B12 and could offer a sustainable, plant based alternative to animal derived supplements. If follow up studies confirm performance, it may help address B12 deficiency worldwide and enable large scale production.
