You have most likely heard that vitamin B12 is often referred to as the “energy vitamin.” The truth of the matter is that vitamin B12 doesn’t necessarily give you energy, but it is a “key” that unlocks the potential for you having more energy.Fatigue, poor concentration, depression, anxiety and irritability are symptoms of B vitamin deficiency and vitamin B12 works with the other B vitamins to help you maintain your energy and brain function. These B vitamins as a whole are responsible for maintaining your brain cells as well as metabolizing the nutrients in foods. Vitamin B12 is particularly important for unlocking your food’s protein.Because vitamin B12 is involved in maintaining the proper function of the nervous system and it is utilized in the production of red blood cells. When your nervous system functions properly and you have sufficient red blood cells then you naturally have more energy. This is because your body is receiving proper stimuli from nerve cells and an increase in red blood cells also means you have an increase in the amount of oxygen transported to your organs.Vitamin B12 is also required in metabolizing protein and carbohydrates. Both of these nutrients are vital in providing your body the key components it needs to provide the body with ATP for energy.Additionally, vitamin B12 and vitamin B6 combined is helpful in lowering homocysteine levels in the body. Research has shown us that homocysteine levels are directly associated with heart disease and heart attacks. By ensuring that you are receiving these two vitamins in adequate amounts, you are able to prevent the conversion of homocysteine into LDL cholesterol, also known as “bad cholesterol.” This naturally allows you to have more energy because your heart is working properly and not being slowed by heart disease and clogged arteries.In a nutshell, vitamin B12 is vital for energy, but it is best when used in combination with the other B vitamins, as they work together to help unlock the components in your diet that assist you in having more energy.
