  • Supports cardio health by neutralizing harmful homocysteine

  • Particularly helpful for people with dietary restrictions

  • 500 mcg per capsule

Swanson Vitamin B-12 is an essential vitamin for overall health and well-being. It is best known for producing energy in the body and 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.

great product I really like this B12 supplement. It's small and easy to swallow. Helps me keep an upbeat attitude. December 4, 2013
Vitamin B12 I just started taking these and within a week noticed marked improvement with my energy levels. December 2, 2013
Good product! You can't beat the quality, price and convenience of this product. Far better than when I was purchasing store brands at the local pharmacy and/or department store pharmacies. October 25, 2013
Great product Great product very happy with the quality October 18, 2013
Not Perfect But Good Cobalamin in this form is not as effective as it would be in other forms. But this product has such a high amount that it is still effective as a supplement. August 16, 2013
Excellent product! Although I now use the B12 that goes under the tongue - I will say these did help with energy. July 1, 2013
Best price and product. One of three of the B-12 vitamins I take everyday to keep my energy up. Works! May 25, 2013
Energy! I have tried many B12 suppliments, and most of them make me Jittery, nervous, and some of them gave me a bad headache. I love this product!!! I provides the energy, and the other benefits that I like, and no adverse side affects. May 15, 2013
Good value for a Great Vitamin Everything I have read for several years has always recommended Vitamin B-12 as we get older. The Swanson's selection of products makes this an easy selection to keep us on track with our health goals. May 4, 2013
Blood tests better I bought this B12 product because my lab tests showed I was deficient. After taking this product for 3 months, my lab tested normal for B12. April 24, 2013
I take it everyday Great for people who don't eat red meat like myself. I take it every morning and it gives me energy. April 23, 2013
LOVE, LOVE, LOVE I have been taking B-12 for a short time now, I have noticed something not sure what yet, but it's a good feeling. I take so many different supplements that I'm not really sure which ones are doing what, but my energy and well-being do seem to be increasing. It's called trial and error. So far so good. My husband and I LOVE Swanson, we are long time customers and tell everyone about Swanson. Keep up the good work. March 31, 2013
Great product Very reasonable prices, great way to supplement one's diet. We absorb less B-12 as we age, so this assures that I'm getting a good supply to my body. Very important vitamin for good health. March 24, 2013
Perfect for Vegetarians I love these tiny capsules because they are easy to swallow. The quality is great, and they ensure that I get all the B12 my body needs so I don't have to worry about becoming deficient. I highly recommend this B12 supplement to everyone especially those who are vegetarians or vegans. January 4, 2013
Best value ever! No need for any of those pseudo-energy drinks out there when you have this supplement. Well worth this minuscule price! I recommend it to everyone! January 3, 2013
Eureka! I have more energy thanks to B12. Before taking I was getting exhausted around 4pm everyday. Now, I have enough energy to make it to the gym, run evening errands, etc. Please try for a pick me up! December 14, 2012
Just what i needed Love how many there are in a bottle. these pills will last me along time because you only need 1 per day November 13, 2012
For the Long Haul Taking vitamin B-12 among with a good diet and proper nutrition gives my wife and I all day energy to do the things in life that we want. November 12, 2012
B-12 Swanson's B-12 500 mcg is just one of the vitamins I take that I can definitely feel an increase in my energy level. It's not something I take everyday. "For me" it's the times when I need an extra boost; or many times I think my day is over (exercise, activity wise); I'll receive a call from a friend that wants to play a couple sets of tennis or try get 18 in before it's dark. I KNOW I can take a B-12 capsule and before long I feel like new!! I'm not close to 18 anymore and I can use all the help I can get. Swanson's Vitamin B-12 is just one of their products I use & can count on for extra energy! October 3, 2012
great product product performed as advertised and is a quality I have grown to accept July 12, 2012
Best B-12 This is the best B-12 I have tried. I have more energy since I started taking these. I also like the small capsule. April 7, 2012
itching side effect after taking 1,000 mcg for only two days I had terrible itching. oncologist said it could be from the pink dye that is added. if you start itching, stop use & try another B12 brand April 6, 2010
this comes in a little capsule, easy to swallow and you don't have to wait for a sub lingual type pill to dissolve under your tongue. You must be able to absorb b-12 orally though. March 10, 2010
Best Value for Price I would say that this is as good a value and price you can get anywhere for any similar item. It meets all my expectations with a very competative price. January 27, 2010
