  • Supports cardio health by neutralizing harmful homocysteine



  • Particularly helpful for people with dietary restrictions



  • 500 mcg per capsule


The vitamin for vascular health, vim, and vigor is Swanson Vitamin B-12! Vitamin B-12 is commonly associated with energy because it plays a vital role in the formation of the red blood cells that deliver oxygen to all parts of the body. It also supports cardiovascular health by working with vitamin B-6 and folic acid to help neutralize harmful homocysteine. While adequate B-12 intake is important for everyone, supplementation may be particularly helpful for some people because the vitamin is found primarily in animal-based foods.

Vit. B 12 I ordered these and haven't been extremely pleased with them. I truly think the liquid is the best thing you sell in the B12 so I'm going to go back to it. I can't tell any difference when I take these vitamins. June 12, 2014

works great I have noticeably more energy when I take this product than when I do not. I am also less irritable. December 12, 2012
Great Price I take B12 regularly because I'm a vegetarian. It's hard to tell if it does anything because I take a lot of other supplements along with B12. Some days though, when I'm tired from not getting enough sleep, I've noticed that taking B12 helps me to stay awake and more focused. March 30, 2012
great/helpful I would buy this again, really works great! I take one in the morning and one in the afternoon. Keeps me going. November 19, 2011
