Vitamin B12 assists the HCG in further break down of the nutrients for maximum absorption and delivering it to vital organs. Another use of Vitamin B12 is to boost the energy levels especially when you are on a low-calorie diet. When the energy level is high, you won’t feel any hunger pangs.
Another advantage of Vitamin B12 is to prevent fatigue, depression, anxiety, enhance digestion, and boost the immune system. It also gives you mental clarity on the HCG diet program.
