Increase energy levels exponentially with Bricker Labs flavorful Raspberry B-12 Blast liquid supplement! Vitamin B12 is one of many essential nutrients our body requires on a daily basis. Proper intake is vital and demanded by the body to maintain healthy nerve cells, red blood cells, and is also needed to make DNA. It is one of eight water soluble B vitamins, all of which assist the body's primary energy source by converting carbohydrates into glucose. Un other water soluble nutrients, vitamin B12 is stored in the liver, kidney and other body tissues. As a result, signs and symptoms of vitamin B12 deficiency may not show themselves for 5 to 6 years. B12 deficiencies typically affect the brain and nervous system first and may result in impaired nerve function, which can cause numbness, pins and needles sensations, or a burning feeling. B12 deficiency can also impair mental function. B-12 Blast combines 1,000mcg vitamin B12 with 400mg of Folic Acid to promote homocysteine metabolism and reduce the overall levels of homocysteine. Homocysteine is an amino acid (a building block of protein) produced in the body. High levels in the blood can cause cholesterol to change to low-density lipoprotein, which damages the arteries. In addition high homocysteine levels may make blood clotting easier than it should, increase the risk of blood vessel blockages and may cause problems with blood flow. B12, Folic Acid functions as a "methyl donor." A methyl donor is a compound that carries and donates methyl groups (a molecule of one carbon and three hydrogen molecules) to other molecules, including cell membrane components and neurotransmitters. As a methyl donor, vitamin B12 is involved in homocysteine metabolism and allows homocysteine to be converted into useful amino acids utilized by the body for proper energy metabolism, immune function and nerve function.
