WHAT IS VITAMIN B12? Vitamin B12 is necessary for the formation of red blood cells that carry oxygen and nutrients around our bodies. It's also important for your immune health, normal psychological function, and normal energy-yielding metabolism.
WHY CHOOSE HEALTHSPAN? They use the methylcobalamin form of vitamin B12 as a natural alternative that is found in foods and the human body, replacing the more commonly used cyanocobalamin. This also results in a much smaller, easy-to-swallow tablet.
QUALITY INGREDIENTS FIRST: Healthspan work harder to seek out the best-quality ingredients for their supplements. They source and manufacture their range, ensuring optimal purity and quality along the way so whether it is faster-acting, better-absorbed, filtered for optimal purity or simply contains more active ingredients, they're confident you won't find better quality.
INNOVATIVE SOLUTIONS, BACKED BY EXPERTS: Healthspan has 25 years' experience working closely with trusted research partners and experts. They thoroughly test and perfect their products with in-house doctors and nutritionists to bring you the latest developments in nutritional supplements.
