This brand has been a game changer for me. Apparently my body doesn’t methylize some vitamins~especially B vitamins. This is a critical component in your health!! I used to have multiple ulcers in my mouth, cuts on my cuticles, no energy amongst many other health issues. I knew something was severely wrong with me. I had so many tests done & they even analyzed my blood….the doctors just all said “we don’t know what’s wrong” and wrote me off. So I went & talked to a naturalist that worked at our local compound pharmacy and she said immediately, “that sounds like you’re not methylating your B vitamins~here try this product!” Then she handed me this Xymogen Methyl Protect & changed the rest of my life for the better!! Within two days my health got incredibly better!! I can not begin to explain the complicated science behind this product or this biological process that our bodies perform, what I can tell you is that this product WORKS for me!! I will take this brand & this specific product for the rest of my life!! **This is my own personal experience with this product. I attached a QR code in the pictures in case anyone would like to look into this brand of products.
