B-12 for Health
You’ve probably heard that vitamin B-12 is good for cardiovascular health. The way that works is this…
Homocysteine is a protein that naturally forms as a byproduct of your body’s processes. When it builds up, it can corrode and inflame arteries and blood vessels, placing strain on the heart and cardiovascular system. Vitamin B-12 helps converts homocysteine to methionine, a protein the body uses for positive, essential activities.
2. Supports Energy Levels
One of the positive, essential activities that methionine is involved with is cellular energy creation.
3. Promotes Normal DNA and RNA Replication
Your body’s genetic material, DNA and RNA, need vitamin B-12 and folate (Vitamin B9) to replicate correctly. Without it, genetic material can be damaged and lead to mutations. Some speculation has even risen that low B-12 levels are associated with an increased risk of breast cancer.
4. Protects the Nervous System
In addition to converting homocysteine, the methylcobalamin form of B-12 encourages the formation of a protective covering for nerve cells called myelin. This covering protects nerve cells from free radicals and toxins which may be in the blood stream.
5. Protects the Brain, Too
The methylcobalamin form of B12 circulates in the blood stream and can cross the blood-brain barrier to support brain cells just as it protects nerve cells. In one study, 77 patients suffering from Alzheimer’s Disease had significantly lower vitamin B12 levels than individuals in the control group. [1] Other symptoms of low B12 levels include numbness in the hands and feet, memory loss, and disorientation.
6. Encourages a Balanced Mood
Vitamin B-12 plays a role in the creation of serotonin, a chemical that influences brain function and overall mood. In one study researchers examined the effect of B-12 on the brains of diabetic patients who experienced mood imbalances. The diabetic patients with normal levels of B-12 enjoyed better cognitive performance and lower incidence of depression compared to B-12 deficient patients. [2]
