Vitamin B12 is a vital nutrient that helps to produce healthy red blood cells. It also feeds the nervous system and brain, and aids DNA synthesis. It can be manufactured in a laboratory and sold as a supplement. However, it is naturally found in meat, dairy, and fish products.
Some people are deficient in a protein which helps the body absorb vitamin B12. If they do not get enough vitamin B12, they are more likely to develop anemia. This can make them feel tired and weak.
B12 Health Benefits
Prevention of Depression and Treatment
Vitamin B12 deficiency may cause clinical depression, as this vitamin is required for serotonin production. In one study, it was found that older women who were impaired and had a B12 deficit experienced severe depression twice as often as those without.
A higher intake of vitamin B12 has also been linked with a higher likelihood of remission for major depression disorder.
Reduced Probability of Macular Degeneration
In one study, supplementing with vitamins B12, B6, and folic acid may reduce the risk of age-related vision loss in older people. In a study of 5,000 women over 40, supplementing their diet with B12 and B6 and folic acids resulted in fewer cases of macular degeneration. The risk of severe deterioration in this group was 41% less.
Improved Brain Health
Vitamin B12 is essential for the brain’s neurones. Brain atrophy is associated with dementia and memory loss.
In a randomized trial, elderly people with early stage dementia who took vitamin B12 supplements in order to lower their blood homocysteine experienced a decrease in cognitive and clinical decline. Low B12 levels are also a factor for poor memory, even if they are in the normal range. More research is needed before scientists can be certain of the effects of B12 supplements on dementia and memory losses.
Where Can You Find Vitamin B12?
You must ensure that you consume enough vitamin B12 in your diet. If you are not able to absorb enough B12 or have a medical problem that makes it difficult to do so, taking supplements is a great way to boost your intake. It is naturally found in dairy, meats, and fish. Many foods are fortified, including cereals.
Summary
B12 has many other benefits besides the ones mentioned above. It regulates a variety of bodily functions, which may enhance your health. Talk to your doctor if you’re worried about B12 levels.
