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.

Rated 5 out of 5 by gr8 stuff this sure has helped me as far as my energy level March 29, 2016
Rated 5 out of 5 by Great Amendment to Multi-B's I buy this for my wife, who by the urging of her doctor is amending her normal mutli-B vitamin intake with this B 12 product. She also takes Inositol to help absorb and metabolize the B vitamins. She's been taking this B 12 for a couple of years now and seems good with it. March 19, 2016
Rated 5 out of 5 by B 12 great product and great prices February 2, 2016
Rated 5 out of 5 by Supplement for metabolism Excellent metabolism maintenance supplement. December 19, 2015
Rated 5 out of 5 by Swanson B-12 B-12 is good for so many reasons. I can't tell you, so you'll have to go look it up. Add this to your daily routine. Great low price too! October 23, 2015
Rated 2 out of 5 by Wrong form methylcobalamin is FAR superior to the cyano form of vitamin B12. Sublingual is the way to take methylcobalamin. Don't waste your time with cyanocobalamin. February 26, 2015
Rated 5 out of 5 by Swansons B-12 is awesome I have tried several other B-12's, I just can't start my day without these. At my house we love caps not tablets, perfect price, for 250 caps. I order 3/4 bottles at a time and these are stored in my favorites for easy ordering. February 22, 2015
Rated 5 out of 5 by Swanson's B-12 What a great little vitamin, and what a great price! Extra energy when I need it and a little more brain boost. Doses in a multi-vitamin are far too low. Go for this one! Thanks Swanson! September 16, 2014
Rated 5 out of 5 by Objective accomplished The capsules are, to me, a much more preferable form for supplements rather than tablets. They are esier to swallow and my notion is that their contents are made available more quickly. The capsules accomplish what I purchased a B12 supplement to get. July 28, 2014
Rated 5 out of 5 by great product I really like this B12 supplement. It's small and easy to swallow. Helps me keep an upbeat attitude. December 4, 2013
Rated 5 out of 5 by Vitamin B12 I just started taking these and within a week noticed marked improvement with my energy levels. December 2, 2013
Rated 5 out of 5 by 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
Rated 5 out of 5 by Great product Great product very happy with the quality October 18, 2013
Rated 5 out of 5 by 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
Rated 5 out of 5 by Excellent product! Although I now use the B12 that goes under the tongue - I will say these did help with energy. July 1, 2013
Rated 5 out of 5 by Best price and product. One of three of the B-12 vitamins I take everyday to keep my energy up. Works! May 25, 2013
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
