Metagenics brings you this synergistic combination of vitamin B 12, folate and intrinsic factor to support the nervous system and cardiovascular health. Intrinsic factor is a protein that’s naturally made in the stomach and it’s added for advanced absorption and uptake. B12 also helps to produce red blood cells and haemoglobin which is why a lack of B12 can leave you feeling fatigued. Folate is a natural form of vitamin B9 that supports immune system health, cell function and energy levels. Support your nerve and circulatory health with Metagenics Intrinsi B12-Folate now!
