Vitamin B12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins. It's normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid metabolism and amino acid metabolism. Metabolism within the body includes the processes of energy generation and use; including nutrition, digestion, absorption, elimination, respiration, circulation, and temperature regulation.¹

There are many significant reported benefits of B12 which is why it has become very widely used and considered an important part of vitamin supplementation. It is needed to convert carbohydrates into glucose in the body, thus leading to energy production and a decrease in fatigue and lethargy in the body. It helps maintain a healthy digestive system, and is essential for healthy skin, hair, and nails. Vitamin B12 also protects against heart disease by curbing and improving unhealthy cholesterol levels, protecting against stroke, and high blood pressure. Vitamin B 12 helps protect against cancers including breast, colon, lung, and prostate cancer.²

When vitamin B12 levels in the body are too low it can result in a host of problems like anemia, fatigue, weakness, constipation, loss of appetite, depression, poor memory, soreness of the mouth, asthma, vision problems, and a low sperm count.

Unfortunately, B12 is not well absorbed when taken orally especially if there are any active digestive issues present. For this reason B12 shots have become commonly used and very popular with healthcare professionals, dietitians, weight loss providers, and fitness professionals.
