WHAT IS B12?
Vitamin B-12, or cobalamin, is a nutrient you need for good health. It’s one of eight B vitamins that help the body convert the food you eat into glucose, which gives you energy.
WHAT IS BENEFITS OF B12?
- Energy Boost - All B vitamins play an important role in your body’s energy production, though they don’t necessarily provide energy themselves. Currently, there is no scientific evidence to suggest that vitamin B12 supplements can boost energy in those with sufficient levels of this vitamin. On the other hand, if you’re significantly deficient in vitamin B12, taking a supplement or increasing your intake will likely improve your energy level. In fact, one of the most common early signs of vitamin B12 deficiency is fatigue or lack of energy.
- Support Bone Health - Maintaining adequate vitamin B12 levels may support bone health. One study in more than 2,500 adults showed that people with a vitamin B12 deficiency also had lower than normal bone mineral density. Bones with decreased mineral density can become delicate and fragile over time, leading to an increased risk of osteoporosis.
- Improve Mood - B12 plays a vital role in synthesizing and metabolizing serotonin, a chemical responsible for regulating mood. Studies support the use of vitamin B12 supplements for improving symptoms of depression in people deficient in this vitamin. One study in people with depression and low vitamin B12 levels found that those who received both antidepressants and vitamin B12 were more likely to show improved depressive symptoms, compared to those treated with antidepressants alone.
- Brain Health - Vitamin B12 deficiency has been associated with memory loss, especially in older adults. The vitamin may play a role in preventing brain atrophy, which is the loss of neurons in the brain and often associated with memory loss or dementia. One study in people with early-stage dementia showed that a combination of vitamin B12 and omega-3 fatty acid supplements slowed mental decline. Another study found that even vitamin B12 levels on the low side of normal can contribute to poor memory performance. As a result, supplementing with this vitamin may improve memory, even in the absence of a clinically diagnosed deficiency.
