Vitamin B12 500™

Andrew Lessman's Vitamin B12 delivers one of the most important B-Complex vitamins in the form of our proprietary, absorption-protected Methylcobalamin (Natural Coenzyme Vitamin B12). Our natural methylcobalamin is protected from stomach acid so it can release its benefits in the small intestine where it can be absorbed, and is essential for metabolic health, which includes carbohydrate and fat metabolism, and thereby, energy production. Vitamin B12 also supports heart and brain health as well as the creation of hemoglobin, without which vital oxygen cannot be transported throughout the body. Our Vitamin B12 ensures the benefits you seek in a small, easy-to-swallow capsule that is gentle to even sensitive stomachs.

Product Information


Vitamin B12 500 delivers an exceptionally high potency (500 mcg) of our unique absorption-protected methylcobalamin (natural coenzyme vitamin B12). Among the B-vitamins, B12 is not just the most important from a functional standpoint, but also because of its limited availability from the diet and extremely difficult absorption. Vitamin B12’s challenged absorption stems from its unusually large size and complex molecular structure. Vitamin B12 is essential for energy production, including carbohydrate and fat metabolism, as well as the creation of hemoglobin, without which, vital oxygen cannot be transported throughout the body. Vitamin B12 is also required for the synthesis of our genetic material (DNA and RNA) and is therefore required for normal cell growth and development. Vitamin B12 supports heart and brain health by supporting homocysteine metabolism.

Typical supplements deliver vitamin B12 in the highly inferior, unnatural form of cyanocobalamin. As its name implies, cyanocobalamin can deliver trace amounts of cyanide – an undesirable toxic chemical. No quality product would use cyanocobalamin. The large molecular size of vitamin B12 makes it highly susceptible to destruction in the digestive system, which is why our natural methylcobalamin is protected from stomach acid so it can release its benefits in the small intestine where it can be absorbed. It is the most intelligent and effective way to orally deliver B12’s benefits. It is well-established that stress, aging and digestive issues reduce B12’s already poor absorption, so given its critical functions, one should carefully consider supplementing this difficult to find and hard to absorb vitamin. Our Vitamin B12 500 overcomes all of the problems of typical B12 supplements and ensures the benefits you seek in a small easy-to-swallow capsule that is gentle to even sensitive stomachs.

Quality Product... I have been taking this product for a few years now. I feel like it's made a huge difference. I also have a very sensitive stomach and I have a hard time taking supplements of any kind. I have never had any problems with any of Andrew's products. Andrew's products are high quality, and put my trust in his knowledge. Thank you Andrew.

Happy with my results! I used to get b12 shots. I started taking Lessman vitamins and I do not have to go for shots anymore. I brought in all the supplements to my doctor and he felt good about these products. I do have thyroid disease and see my doctor regularly. His supplements have helped me feel better and my doctor also suggests how much I should be taking. I'm not claiming this is cure, simply a part of taking care of me and trying to live a healthier lifestyle along with supplements that my body lacks based on lab work. My doctor and I are happy with my lab results. Im really able to feel a difference and see it in my labs. So thankful for his products.

It changed my life! I'm ALIVE! I am a 32 year old female. A vegetarian from birth. I have ALWAYS felt tired and mentally foggy. As a child, I wanted to play outside, but I was too tired. I remember being 9 years old, and when it was not a school day, I could sleep in until 3pm, because I was so tired! As a teenager, my mind was foggy and it took all my mental strength to pay attention in school and finish my homework. I burned myself out in college and grad-school, to the point that all I thought about was what time I was going to get to bed and how many hours of sleep I was going to get, before I had to get up and get through one more day. I lived one day at a time wondering how people got stuff done with such energy and without effort. When I started working, I would go to work every morning, and without noticing, I would say to my office mate, "I am soooo tired!!!". After 3 years of me saying this to her every day (EVERY DAY!), she said, "I'm tired of hearing you say you are tired every day, why don't you try Andrew Lessman's B-12 vitamin?" (I know this sounds like a commercial, but it is the truth!) I said to her, that I already took a B-12 vitamin. She said, "not Andrew Lessman's B-12!". She said she would bring me some of hers and gave me 2 weeks worth... I HAVE NEVER SAID I AM TIRED AGAIN!!! From day number one, it worked. Now, I want to clean my house, go to the store, go camping, go to the movies, get ready for work and get up early to put on my make-up. I can pay attention and concentrate on several things all at the same time! I go out with my friends; I actually call them, and ask them to go out, because I have the energy to do all of it and more!!! Thank you Andrew Lessman!!! Thanks to you for the first time in my life, I am not a zombie, I am alive!!! If you are a vegetarian, do not go one more day without this product, it will change your life!
