Andrew Lessman’s VITAMIN B12-500 delivers 500 mcg of natural Vitamin B12, which is generally viewed as the most important of all the B-Complex vitamins to supplement. This importance stems from B12’s long list of critical functions and the fact that it is by far the most difficult of all vitamins to absorb. Vitamin B12 is essential for all energy production given its critical role in the creation of hemoglobin without which oxygen is not transported and no energy created. Vitamin B12’s role in energy production does not end there, since we also cannot metabolize carbohydrates or burn fat without Vitamin B12. Perhaps even more important is B12’s vital role in the synthesis of our genetic material and its requirement for normal cell growth and development. Vitamin B12 also supports heart health due to its ability to help metabolize homocysteine, and B12 is also essential to support healthy immune and nervous system function. Like all the B-Complex vitamins, B12 is easily depleted by stress, but its enormous molecular size makes it by far the most difficult of all vitamins to absorb. It is also well-established that stress, aging and digestive issues only further reduce Vitamin B12’s already poor absorption. Equally well established are the failings of typical B12 supplements whose contents are easily destroyed by stomach acid. Our unique Vitamin B12 is protected from stomach acidity and its B12 is released in the small intestine where it can be absorbed. Given all the critical functions of Vitamin B12, along with its extremely poor absorption from food and ordinary supplements, we should all carefully consider a plan to intelligently supplement. Best of all, our Vitamin B12-500 is a pleasure to use, since it comes in a small, soft, easy-to-swallow capsule and is designed to be gentle even to the most sensitive stomachs.
