Formula works well for me
The ingredients work well for me. The B 12 is made from a natural source and it is at higher than average dose of 1,000 mg, (natural source of Methylcoba... .) I had a B12 deficiency, so far down that I had enemia. After taking the natural B12 ( with larges dosages than just the multi), for 3 months it is now shown as "high." I've also learned that Thiamin, B1, is also often low in people. So I'm very glad this multi has a high dosage of 60 mg, that is 5,000% of the "daily value." Some multi B vitamin products show the same amount for just about every vitamin listed, like all 50 mg. However this vitamin is more specific. I appreciate it that all the amounts are relatively high. A good bargain.

What a Steal!...Great Product!...Contains 100% methyl-Folate/Quatrefolic/5-MthF!
Thrilled to find methylated/co-enzyme/active B-Vitamins at such a great price. Methylated B vits. are fully active, your body does not have to 'convert' these in to a usable form - they are already fully absorbable & ready to get to work in your body - - unlike 'old-fashioned'! non-methylated B's (i.e.: B50 complexes & the like) which actually require your body to 'convert' those to a usable form, this process itself is difficult for the body/liver & more so for certain genetic 'mutants'! - Long story short - methylated/activated/co-enzyme B-Vitamins are far superior (my opinion!) & better absorbed than the kind of B-complexes you might find at your local drug-store or Gas Station .... I used to use Jarrow 'B-right' but they changed the formula to contain a mix of synthetic/fake Folic acid & 5-mthf, whereas the Doctors Best brand contains 100% Quatrefolic (5mthf) - so Doctors Best is my preferred choice now! .... I get a definite boost in energy & mental clarity .... I take these every day along side my Amino Acids - the B's ensure that the Aminos can do their job And of course a healthy daily intake of B's is essential for practically every process in the body & to help the Liver keep on humming-along! Two big thumbs up for Doctors Best fully Active B-complex! The product got here (Hawaii) very quickly - 2 days faster than anticipated arrival! Amazon outdoes itself yet again!

Heads up - Formula changed
It's a good B complex, but just beware, they recently changed the formula to use nicotinic acid, which causes a flush effect in most people, especially on an empty stomach. If you've experienced this before and aren't a fan, definitely look for a complex without nicotinic acid.

Not what I thought
Be careful and consult doctors first had a very bad reaction. Extremely yellow urine that smelled guess it was normal. Reaction really frightening.

Very good w/o negative side effects
As a plant based eater, I have taken a vegan B12 supplement for years. Recently, I ran out and was โtoo busyโ to order more. After a couple months, I noticed having low energy especially in the afternoons and then started having heart palpitations. I went to the doctor to be safe, and confirmed that everything was good except my B12 was on the bottom end of the โnormal range.โ I ordered this B complex, and within less than 2 weeks of taking it daily, the palpitations were gone and energy is coming back. Lesson learned. This is a great oral supplement and seems to be very effective without any negative side effects.

Used for years! Feel the kick!
Well, these things are the B supplement we have been waiting for! My therapist taught me a bit about methylation and how a great many people do have issues with it. So here we go on the hunt. After trying a couple of other supplements with methylated B vitamin complex, this one delivers the same great results as the other brands while being an excellent value. My meds really drain me and eating too much makes me sleep. This just helps me with everything. I have begun to insist that my husband take this daily as well. If I don't I can tell I forgot! Now this will make your urine so yellow it is a bit frightening. I also have been told by a few clinicians not to have this supplement after 6 pm. because it can exacerbate insomnia.
