  • Helps you feel more energetic

  • Plays a key role in the formation of the red blood cells that carry oxygen to different parts of the body*

  • Supports cardio health by neutralizing homocysteine*

Promote energy and cardiovascular health with Swanson Vitamin B-12!* This essential vitamin helps form red blood cells that deliver oxygen to all parts of the body, which in turn promotes energy.* 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.

Customer Ratings & Reviews

Vitamin B-12 is rated 4.8 out of 5 by 14.
Rated 5 out of 5 by from Good It's cheap so I can try 'em out. at .99 you don't feel like it's a big loss if you don't like it or bother to take it. They seem like any other B12 to me. .99 for a month worth is a good deal.

Rated 4 out of 5 by from Good Good product but doesn't give you the energy as I've tried with others. Very much healthier though.

Rated 5 out of 5 by from Vitamin B12 These are easy to tell apart from all of the other pills that I take daily. And they are very tiny capsules that I can tell apart from other capsules. I don't know how they work, but I trust them!

Rated 5 out of 5 by from Great Product I love this product. The capsules are very small and easy to swallow and you can't beat the price. I noticed a difference with my energy and libido. Also my sleeping patterns have improved.

Rated 5 out of 5 by from AWESOME I suffer from having low energy and am usually fatigued even when I wake up in the morning. I have tried everything, even getting support memory foam for my mattress. Nothing has worked, until I started taking B12. This has helped me feel more naturally energized throughout the day with no side effects what so ever. I will continue to take these from now on. I have just ordered about 6 more bottles to stock up for a while.

Rated 5 out of 5 by from Great Product This B-12 is more than reasonably priced and totally worth every penny and even more! When my husband and I first started taking B-12, we both noticed a difference in our energy level immediately. The longer and more consistently we took it, the less we noticed an actual difference, but instead realized that we were just getting used to the energy. Now if I go without B-12 for a few days or more, I notice that I am without energy and will take a B-12 for a boost. It's absolutely great! I have never taken any of those energy drinks because I hate the smell and can't imagine how bad they must be for you. I am a B-12 believer all the way!

Rated 4 out of 5 by from I bought it because it was a good deal. Just a regular vitamin B12, but cheaper than anywhere else.
