Health Benefits of Vitamin B12

· Protect Against Heart Disease -
Adequate levels of vitamins B12, B6, and B9 have been shown to lower levels of a protein in the blood: homocysteine. Lower levels of homocysteine has been shown to improve endothelial function, which in turn may boost cardiovascular health and decrease risk of heart attacks.

· Protect and Repair DNA to Reduce Cancer Risk and Slow Aging -
Absorption of vitamin b12 and Folate (B9) is essential for DNA metabolism and maintenance which helps to prevent cancer and slow aging.

· Protect Against Dementia and Cognitive Decline -
Lack of vitamin B12 increases homocysteine levels, which in turn decreases the bodies ability to metabolize neurotransmitters. Due to limitations with creating long term controlled studies in human populations, no definite link between increased vitamin B12 levels and cognitive function have been found,however several observational studies suggest increased homocysteine levels increase the incidence of Alzheimer's disease and dementia, and low levels of vitamin B12 has been associated with cognitive decline.

· Alzheimer's Protection -
A study has shown that a deficiency in Vitamin B12 and Folate (B9) can double the risk of Alzheimer's Disease.

· Energy and Endurance -
A lack of vitamin B12 will lead to anemia and weakness. Adequate levels of vitamin B12 are necessary to maintain normal energy levels. Claims of vitamin B12 as an energy or atheletic enhancer remain unproven.
