Vitamin B12 is a great energy booster. It works through the red blood cells by enabling them to carry oxygen more efficiently. An oxygenated cell is a cell that is at its optimum, full of energy, and won’t tire easily. B12 is also great for the skin. These are just some of the benefits – overall, it’s an essential vitamin that the body must have to stay in balance. The only problem is that B12 is not that easily found in food – very few foods are B12-rich and they are essentially meat, eggs, and fermented foods.
