What does Vitamin B12 do?

Vitamin B12 supports protein and fat metabolism, cardiovascular support, nerve fiber support, cognitive support, formation of hemoglobin and prevention of anemia.1 Feeling tired and weak is not just because you are getting older. Vitamin B12 absorption becomes less efficient with age.2 Supplementing B12 has been shown to increase hemoglobin in the blood and increase energy.3

What happens when your Vitamin B12 is low?

When we do not produce enough hemoglobin, we will feel tired and experience weakness, because our hemoglobin is not carrying enough oxygen to the cells in our body.

Deficiency of B12 is linked to lack of focus, impaired cognition, memory loss, forgetfulness, and mental confusion.4 As we age, low B12 levels leading to low hemoglobin can also cause the brain to become atrophied and to shrink. The accelerated rate of brain atrophy in elderly with mild cognitive impairment can be slowed by homocysteine-lowering B vitamins.3

What is Vitamin B12 good for?

B12 is important for producing mood-enhancing neurotransmitters such as dopamine and serotonin, which combat anxiety and depression. B12 deficiency has been associated with higher risk of depression.5 Deficiency can also negatively affect your nervous system, triggering numbness, tingling and pins and needles pain in the hands and feet.4 Nerve function impairments have been linked to increased risk of loss of function and disability in older adults.6

You may say, “I take B12 and continue to experience many of the symptoms listed above.” This could be due to a DNA methylation mutation. The addition of methyl groups to our DNA can affect how some molecules act in the body. One methylation mutation is known as methylenetetrahydrofolate reductase (MTHFR). MTHFR has been associated with Vitamin B12 deficiency.1 Methyl cyanocobalamin is a form of B12 otherwise known as methylated B12, which can be used for those with or without MTHFR.

Which TriVita B-12 supplement is best for you?

Alfred Libby’s Original Sublingual B-12 has 1,000 mcg of cyanocobalamin B12, which works great for most people. There are no natural stimulants in this formula, so it is a good choice for people who might be sensitive to natural-energy stimulants.

Alfred Libby’s Super Sublingual B-12 formula has 3,000 mcg of a combination of methyl cyanocobalamin and cyanocobalamin forms of B12, as well as energy-stimulating ginseng root. This B12 formula works best for those who may not know if they have MTHFR and are looking for additional natural-energy stimulants.

The HCY Guard® formula has 1,000 mcg of methyl cyanocobalamin and no cyanocobalamin or natural stimulants. This formula is best suited for those who have high homocysteine levels, those who do not do well with stimulants, and those known or suspected to have MTHFR.
