Vitamin B12 plays a crucial role in various metabolic functions of the body. It aids in protein synthesis and helps convert fats and carbohydrates into energy. Additionally, B12 supports red blood cell formation, maintains nervous system health, and influences mood and sleep regulation.

This vitamin also impacts other compounds that contribute to the well-being of the brain, heart, and other organs. A deficiency in B12 can result in a decrease in red blood cell production, mood and sleep disturbances, chronic fatigue, and peripheral nerve issues.

Whether you’re an athlete or someone who exercises regularly, maintaining high energy levels is essential. While a balanced diet helps, sometimes an extra boost is needed. B12 not only increases energy but also strengthens the immune system.

Although B12 is primarily found in animal-based foods, absorption depends on several factors. Research suggests that up to 40% of people may have a deficiency, with certain groups being at higher risk. These include vegans, vegetarians, individuals with Crohn’s disease, alcohol dependency, the elderly, and those who have undergone gastric surgery. For these individuals, B12 supplementation is particularly important.
