Live a Healthier and Fuller Life with Our B12 Boost. Vitamin B12 is a vital component of our diet and is found naturally in many foods. However, a high-stress lifestyle, a vegan diet, advancing age, and consumption of excessive amounts of alcohol or caffeine can lead to a deficiency of this vital vitamin. SHarper Plastic and Reconstructive Surgery’s B12 Boost is intended to replenish your body’s B12, banish fatigue and weakness, stimulate your metabolism, and positively impact your body.
