Rated 4.8 out of 5 by 62 reviewers.
Rated 5 out of 5 by Excellent Product I was diagnosed with vitamin-B anemia. Taking regular vitamin B supplements proved ineffective. A doctor suggested looking for an "activated" vitamin B as it would be more available to the body for assimilation. I searched and found this product and voila! It seems that my body can assimilate an activated formula and this formula has been amazing. I would highly recommend this supplement to anyone looking for a high quality B supplement. April 29, 2016
Rated 5 out of 5 by If you want your B's... This is a good supplement. The price is fair, the quality is good, it is convenient to take. April 1, 2016
Rated 5 out of 5 by Nothing like it. I discovered this activated B-complex several years ago and have not been without it since. My digestive tract is very sensitive to so many things, even certain ingredients in some supplements. I have used many vitamin B supplements over the last 30 years of my life. This is the only vitamin B complex supplement I have found that has no negative effects on my sensitive system. I feel better mentally and physically when I take this activated B-complex. My daughter also uses it and she has shared it with several of her coworkers who now also use it. Even though it costs more than the average B-complex supplement, it is worth every penny. November 2, 2015
Rated 5 out of 5 by Great product I like the (activated) vitamins because they are more easily assimilated by the body especially as we grow older. September 27, 2015
Rated 5 out of 5 by Important B vitamins are very important and I believe these are in the correct form. Folate instead of folic acid for example. September 13, 2015
Rated 5 out of 5 by My preferred B-complex sup This is my favorite B-complex product. It contains the active forms of the B-complex vits.. Not everyone can metabolize all B vits to their active forms efficiently; so taking the active forms ensures that your body has what it needs. For example, from genetic testing, I know that my body cannot form the active form of folate efficiently. Activated B-complex costs a bit more, but Swanson had the best price and great sales too.. This is the B-complex I will buy from now on. February 24, 2015
Rated 2 out of 5 by Low Biotin I like this B-Complex better than many. But, this only has 17% Biotin. That's very disappointing. That's not "high potency". I don't want to have to take a separate biotin supplement. I can't understand why they didn't include anywhere near adequate Biotin. Also, Inositol hexanicotinate has been shown to not improve lipids. I would prefer Nicotinic acid. (And, not niacinamide either since it inhibits SIRT1.) I also wish it had more B1. January 1, 2015
Rated 5 out of 5 by great prices Noticed an improvement in energy December 18, 2014
Rated 5 out of 5 by Good Quality, It Works! I have tried several B Complex products and this is the best by far over the others. This one will be one of my Favorites December 12, 2014
Rated 5 out of 5 by best option for B complex When I switched to a bioavailable B complex formula I noticed a subtle increase in energy. My growing understanding of how B complex affects the body lead me to this product. October 7, 2014
Rated 5 out of 5 by Helps with energy I like that this contains methyl B12 and a methyl folate instead of folic acid. I feel it helps me have more energy. July 9, 2014
Rated 5 out of 5 by This product was recommended to me. I was told my body will get what it needs and get rid of the rest, so taking something labeled "high potency" didn't scare me. I recommend for anyone who needs the added B boost in your system. May 9, 2014
Rated 5 out of 5 by Excellent Great for people who are living a highly stressful life. March 22, 2014
Rated 5 out of 5 by super potency It is so potent I ended taking just a half of the capsule . January 14, 2014
Rated 5 out of 5 by Superior B-Complex Formula Swanson has come up with what I feel is THE BEST B-Complex formula available. This exceptional product contains the most biologically active forms of each of the B complex vitamins (1, 2, 3, 5, 6, Folic Acid, B12) in addition to nutrients related to the B family. I have complete faith in this product's ability to deliver the myriad benefits associated with these essential nutrients. December 5, 2013
Rated 5 out of 5 by B-Vitamins These are important for multiple functions of the body. I take it, give it to my husband and let my son take it. It supports your brain! November 30, 2013
Rated 5 out of 5 by Energy Boost! I love this supplement. I truly feel energized and mentally clear each day. November 14, 2013
Rated 5 out of 5 by Well tolerated This is one of the very few B-complexes I can tolerate. I appreciate all the active forms of the b vitamins...especially methylfolate and b12. Great product! October 16, 2013
Rated 5 out of 5 by Bio-Available B Vitamins This is a good value for b vitamins that are bio-available. I need to take this type of b vitamin to even absorb them. I am very pleased with this product. October 3, 2013
Rated 5 out of 5 by This product was easily digestible for me. I was looking to improve my skin, hair, nails. It worked for me. Stress level too! September 10, 2013
Rated 5 out of 5 by Good Value Good way to get all your B vitamins in one. September 3, 2013
Rated 5 out of 5 by Great B-Complex I'm fairly new to Swansons, having just learned about this company earlier this year, but I'm quickly becoming regular. I've been very pleased with each item that I've purchased, and this B-complex is no different. August 8, 2013
Rated 5 out of 5 by The best forms of all B vitamins The most bio-available form of B vitamins. Especially delighted with the quatrefolic/5MTHF form instead of run-of-the-mill folic acid. Thanks, Swanson! Wish you would have this occasionally on a BOGO sale, since it is otherwise a tad pricey. June 2, 2013
Rated 5 out of 5 by Fine I was blind, but now I can see!!! (Just kidding) These do seem to metabolise better than others. I find them quite effective. Not especially cheap, but value is good. May 26, 2013
Rated 5 out of 5 by These B's are an A+ These are the best b complex vitamins that I have ever tried. This bioavailable form is so easy on my stomach. My body could never process the synthetic type of b complex, and I was looking for one that was bioavailable. Great product. April 29, 2013
