"I have tried so many different vitamins, and this one really works. Finally!!! I notice extra energy in the afternoon when I take it. I never noticed it before." ~product review by Jenny50

  • New state-of-the-art B complex

  • Lower dose potency focused on optimum bioavailability

  • Delivered in vegetable capsules

Swanson Ultra® set the standard for advanced B-vitamin supplementation with the original Activated B-Complex. Now by popular request, we've developed a lower-potency version of our best-selling formula that is focused on optimized bioavailability. Both formulas feature the same advanced forms of B-vitamins, including Benfotiamine (thiamin/vitamin B1), Pyridoxal 5-phosphate (P5P/vitamin B6), Methylcobalamin (vitamin B12), patented Pantesin® (pantethine) and revolutionary Quatrefolic® 5-methyltetrahydrofolic acid (folate). These superior forms offer higher bioavailability for reliable supplementation.

Customer Ratings & Reviews

Rated 4.7 out of 5 by 33 reviewers.
Rated 5 out of 5 by Well tolerated I looked a long time before I found a B complex that I could tolerate as so many have a form of niacin I can't take. This one it the best for me and I find it important to my daily health. March 31, 2016
Rated 5 out of 5 by I have tried several different brands before turning to this Vitamin B. I have to admit this one really works and is great! January 13, 2016
Rated 5 out of 5 by great product i was thrilled to find this product which has multiple b vitamins. great quality. great price. so glad to have discovered this product. January 4, 2016
Rated 5 out of 5 by Best multi B-Complex This is the first multi-B-Complex vitamin I've found that contains all the most readily absorbed B vitamin compounds, especially B-12 (as methylcobalamin) and Folate (as 5-MTHF). I was told by a pharmacist several years ago that these are only ones I should take, but these particular forms are not usually found in multi-vitamin formulas. November 23, 2015
Rated 5 out of 5 by Unique product Trying to get a combination of methylated ingredients without having to buy multiple products was frustrating me. Along comes this great combination formula! Has allowed me to replace my standard B supplementation, saving me money and the storage, sorting out, and gobbling of several capsules. Easy on my stomach, too. October 7, 2015
Rated 5 out of 5 by Energy I'm not fully persuaded, because I have no "real" way to determine the bioavailability myself, but I do trust Swanson's quality. Don't know yet if I will stick with this or try a different type. Maybe increasing amount? Yet to be determined. June 4, 2015
Rated 4 out of 5 by I take this B complex with vitamin D3 and C complex plus Alpha Lipoic Acid. Three times per week. The three vitamins plus ALA are synergistic for absorption purposes. February 28, 2015
Rated 2 out of 5 by Inadequate Biotin I like this B-Complex better than many. But, this only has 8% Biotin. That's very disappointing. 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 Activated B Complex I tried others, but I noticed a major difference from the other B-Complex I tried in the past. As always, Swanson is the best! Thank you, Swanson! January 1, 2015
Rated 5 out of 5 by Lower potency I have taken B supplements for years, but only discovered these in the past year or so. I looked for a supplement that was balanced, but lower potency. These seem to be working well for me. December 13, 2014
Rated 5 out of 5 by Best anywhere I was advised to take folate instead of folic acid as my body cannot convert folic acid into folate. This supplement has several methylated B-vitamins and yet is still not as expensive as others elsewhere with the *same* ingredients. I will be taking this the rest of my life. September 21, 2014
Rated 5 out of 5 by THE best Dr recommended a good B complex for me. This has the preferred methelcobolimin a superior form not found in most B complex brands. September 1, 2014
Rated 5 out of 5 by very thankful This works for me, whereas normal B-vitamins (which I tried to take for years) just don't. So glad I found this product. August 23, 2014
Rated 5 out of 5 by More energy and stamina My husband and I feel a significant boost in energy and stamina throughout the day when we take this product in the morning. May 25, 2014
Rated 5 out of 5 by Good Value. High Bioavailability. I was using High Potency version but it was too effective for me so now I use this version. This is highly bioavailable and excellent. April 9, 2014
Rated 5 out of 5 by B Smart This is the smartest b vitamin choice I have ever made. I have tried other b complex vitamins that aren't bioavailable; I can't absorb them and my stomach gets upset. I really like this lower dosage, it makes it easy to take them twice daily. March 5, 2014
Rated 5 out of 5 by High quality I have been using this product for about 3 or 4 months and I feel better. I know my body is absorbing it and using it! March 3, 2014
Rated 5 out of 5 by Really Works I have tried so many different vitamins, and this one really works. Finally!!! I notice extra energy in the afternoon when I take it. I never noticed it before. February 13, 2014
Rated 4 out of 5 by Activated B-Complex Swanson's Ultra Activated B-Complex does not upset my stomach. January 20, 2014
Rated 4 out of 5 by Good product This does help me handle stress better. December 27, 2013
Rated 4 out of 5 by Really good purchase . As far as I can feel , it works well . December 2, 2013
Rated 5 out of 5 by Bioavailability I was introduced to the concept of Bio-available b12 by my PCP. It made sense to me but could not find much locally so when I found the entire complex in this form I was ecstatic. I can definitely tell when I do not take them and appreciate the sense of upliftment when I do. The Swanson shipments always arrive on time and usually early and who can beat the price. Thanks Swanson's October 8, 2013
Rated 5 out of 5 by No Upset Stomach! This one seems to have a lot of "punch" in how it is formulated....and, without upsetting my stomach!!! September 16, 2013
Rated 5 out of 5 by Great Product for Energy One of the better multi-B vitamins I have taken. September 5, 2013
Rated 5 out of 5 by Digestible! I am very happy to tell you that this product does not have odor nor causes stomach upset. I can take B's again!! August 22, 2013
