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.

Activated B-Complex High Bioavailability is rated 4.6 out of 5 by 39.
Rated 4 out of 5 by from Seems to be fine.
Date published: 2017-03-27
Rated 5 out of 5 by from Good Quality Good Value I find this B-complex supplement to be as effective as other brands with 4 times the dosage.
Date published: 2017-02-26
Rated 5 out of 5 by from Folate A vitamin B complex is hard to find without folic acid which I understand is the synthetic form of folate. I will always buy this product because it contains folate which is not the synthetic form. Even though it is a little more expensive, the old adage holds true--you get what you pay for. I hope Swanson Brands never discontinues this product!

Rated 1 out of 5 by from Couldn't sleep After taking one of these B-complex, I had trouble sleeping and staying asleep. I waited a few days and took another at lunch time and had same night of insomnia. I have used this product before and don't remember any problem. Soon, I will try again. I wonder if some ingredient has changed.

Rated 5 out of 5 by from Awesome B Complex! This B Complex is great. It is highly effective in bringing up my Vitamin B and at a valuable price compared to the local drugstore. I highly recommend this product.
Date published: 2016-08-11
Rated 4 out of 5 by from Works Well This B complex has done wonders for me. It took about 4 months to notice a big difference but I have much more energy now and my skin looks better.
Date published: 2016-07-25
Rated 5 out of 5 by from 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.
Date published: 2016-03-31
Rated 5 out of 5 by from I have tried several different brands before turning to this Vitamin B. I have to admit this one really works and is great!
Date published: 2016-01-14
Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
Date published: 2015-06-04
Rated 4 out of 5 by from 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.
Date published: 2015-03-01
Rated 2 out of 5 by from 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.

Rated 5 out of 5 by from 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!
Date published: 2015-01-01
Rated 5 out of 5 by from 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.
Date published: 2014-12-13
Rated 5 out of 5 by from 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.
Date published: 2014-09-22
Rated 5 out of 5 by from 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.
Date published: 2014-09-01
Rated 5 out of 5 by from 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.
Date published: 2014-08-23
Rated 5 out of 5 by from 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.
Date published: 2014-05-25
Rated 5 out of 5 by from 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.
Date published: 2014-04-09
Rated 5 out of 5 by from 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.
Date published: 2014-03-05
Rated 5 out of 5 by from 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!
