EXCERPTS: . . . a new study from Cornell University suggests that B12 may do much more than we thought. The researchers found that this vitamin may play a big role in how our muscles work, how we use energy, and even how we age.
The study was published in the Journal of Nutrition. It was led by Dr. Martha Field, a nutrition scientist at Cornell. Her team looked deeper into what happens inside the body when someone does not get enough B12...
[...] One of the most surprising results was that low levels of B12 made it harder for muscle cells to make energy. This is important because muscles need a lot of energy to work properly. The researchers saw that older mice with B12 deficiency had weaker muscles and lower muscle mass. When the mice were given B12 supplements, their muscles improved.
[...] The research team also found that B12 interacts with many important systems in the body. These include fat metabolism, how cells respond to stress, and how our genes are controlled.
B12 seems to act like a control switch that helps keep these systems working well. When there isn’t enough B12, it can cause problems even before typical deficiency symptoms show up, like tiredness, nerve issues, or memory loss.
Another key point is that many people may not get enough B12, even if they don’t have a serious deficiency. This is especially true for older adults, people who eat little or no meat, and those with digestive problems.
Some estimates suggest that one in four older adults in richer countries may have low B12 levels. This study suggests that even small shortages of B12 can hurt health over time... (MORE - missing details)
