Fully Active B Complex provides B vitamins that are indispensable for making energy from foods, and for making and maintaining DNA, genes, cells, tissues, organs, and enzyme functions.* Doctorâs Best Fully Active B Complex provides an important set of B Vitamins including fully active folate, Vitamin B6, and Vitamin B12. Supplementing with these B vitamins helps promote optimal health and well-being.*
- Helps to keep body energized
- Helps maintain brain health (memory, mood and other brain functions)
The breakthrough features of this formulation include: supplies only the best-utilized b vitamin forms. Most b vitamin supplements use cheap forms that are not optimally utilized in the body. This formulation does not compromise-it provides generous amounts of the most active b vitamins. Substitutes naturally fully active folate for synthetic folic acid. Folic acid is an artificial folate that is difficult for the body to assimilate. This formulation instead provides the bodys most fully active folate, MTHF (methyl-tetra-hydro-folate). Provides sufficient, fully active vitamin B12. Very few supplements provide sufficient amounts of active vitamin B12. This formulation provides 1000 micrograms of fully active B12 to help ensure excellent oral absorption. Thiamin (“vitamin B1”) is fundamental to human metabolism because it is essential for the metabolism of oxygen. The microscopic “power plants” of our cells (mitochondria) require thiamin to generate energy, but elsewhere in the cells it is also required for energy generation. Thiamin is important for metabolizing amino acids, the building blocks of proteins, but is especially important for managing sugar and other carbohydrates, and can be depleted by high-carbohydrate diets. Thiamine even helps support the delicate blood vessels of the retina and other tissues in the presence of high levels of circulating blood sugar. This vitamin is absorbed only as thiamin (not as other thiamin vitamins) in the upper small intestine. Alcohol can impair the proteins that transport thiamin, and high alcohol consumption is linked to thiamine deficiency. The brain and other nervous tissues have especially high thiamin requirements. Other organs with high oxygen requirements, such as the heart, also have high demand for thiamine.
Common Questions & Answers
Is this made in usa? whether any ingredients are sourced from china?
If it was made in the USA it would say made in the USA. On their container it says ” made for ” Doctors Best. On their website they never say where their products are sourced or manufactured. Doctors Best was acquired by a Chinese firm in 2016. Who knows where it is made or what is in it? I will never buy a Doctors Be…

Can anyone tell me how large the capsules are? I am looking for a supplement for my daughter and she has some trouble swallowing large pills.
Capsules have a rating system like 0,1,2 like small medium and large. This capsule is clear, unmarked and is 3/4 inch in length. It is not a creepy hard tablet that sticks to your throat. I dont think that is considered the large – more medium. It goes down well. For a child though might consider a chewable or liqui…
Capsules have a rating system like 0,1,2 like small medium and large. This capsule is clear, unmarked and is 3/4 inch in length. It is not a creepy hard tablet that sticks to your throat. I dont think that is considered the large – more medium. It goes down well. For a child though might consider a chewable or liquid, although Bs arent that tasty to me. The important thing is to get the Quatrefolic, the Cadillac of the folates. Drs Best has great Bs.
Is this comparable to nutritional yeast?
Better than nutritional yeast, I think. Both are bioactive. Like natural yeast, this complex has the active forms of Bs, so they can be utilized by people who cannot metabolize folic acid and other non-active b vitamins. About 45% of the population have what is called an MTHFR gene mutation, for instance, that doesnt …
Better than nutritional yeast, I think. Both are bioactive. Like natural yeast, this complex has the active forms of Bs, so they can be utilized by people who cannot metabolize folic acid and other non-active b vitamins. About 45% of the population have what is called an MTHFR gene mutation, for instance, that doesnt allow them to metabolize the synthetic form of folate, folic acid. As such, they lose out then on one pathway to healthy methylation – and production of neurotransmitters, hormones, immune and digestion enzymes and more.
But this is a much higher dosage than you can get in nutritional yeast without eating cupsful of it. Its okay if the amounts of b vitamins, which are water-soluable, are high, as your body just burns off what you dont need. But if you are deficient in a particular b vitamin(s), your body may need these higher amounts. Nutritional yeast also needs to be supplemented with a active from of b12, such as methycobalamin, because it doesnt contain B12.
Nutritional yeast would be great for someone who knows they have good b-vitamin values already and are just looking to maintain. But taking a daily active B12 supplement with the yeast would be generally be recommended.
Question: How much of each type of B6 is there?
Answer: Hi there are many types of B vitamins but only one type of B6. This is a great multi-b supplement. If u click on the bottle picture or the wrtten description it will rotate to show the back of the bottle & all ingredients… all those dots at the bottom give a different view of the label. I would order this again
Question: Manufacturer: what is the exact amount of these: pyridoxine hydrochloride, riboflavin, niacin? They were mentioned in combo forms.
Answer: I only know what is shown on the back label.
Are ingredients sourced from china and is it gmo free
The doctors best company was acquired by a Chinese company in 2016. That does not mean the product is inferior. It is manufactured in CA.

The doctors best company was acquired by a Chinese company in 2016. That does not mean the product is inferior. It is manufactured in CA. Their website says “Doctor’s Best products are quality tested and manufactured in the United States using highly qualified cGMP manufacturers and raw material ingredients. (CGMP refers to the Current Good Manufacturing Practice regulations enforced by the FDA) Doctor’s Best sources raw materials from around the world and ingredients are subject to the intense testing and verification regardless of geography of origin.” You can check it out at drbvitamins.com. Some people dont want to buy anything from China. We buy a lot of things there as they are made cheaper, sometimes, and I personally would not eat food from China, but I will take supplements even if the company was bought by China as they go through the US manufacturing standards. I will take vitamins if they are manufactured in the US as we have quality standards in this country. Use your best judgement as to where you think your supplements should originate. I couldnt find any info in the website about GMO.
Question: does this contain niacin?
Answer: Yes. B3 (as niacinamide and niacin) 50 mg
Question: Do these have a vitamin smell?
Answer: I had a serious alergy to this vitamin and had to suspend the use and lost what I have bought.
Good mood, lots of energy!
Great supplement. While taking this I was in a super good mood and had lots of energy… Maybe a little too much energy since I was still wide awake at bedtime. I was taking one at breakfast and one at lunch, so maybe only take it in the morning if you want to sleep at night.UPDATE 7/2019: We found out my husband has the MTHFR Gene mutation, which means our kids might also. I already had this supplement in stock, so he started taking it. He is so much more calm and happy. His stress and anxiety have been reduced significantly. His appetite and sugar cravings have also been reduced and that is causing a reduction in his waistline… I also started opening capsules and mixing into applesauce for the kids. They seem to have fewer meltdowns and are generally more pleasant to have around 🙂
This is the *Best* Choice
Out of all the options on Amazon this is the only one that contains a safe but effective amoun of b9 in the form of methylfolate, no one should take more than 400mcg per day, the dose makes the poison. It also contains a sufficient amount of B6 and B12 which I (and many people) have a genetic predisposition towards not absorbing well.
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 Bs (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 Bs ensure that the Aminos can do their job And of course a healthy daily intake of Bs 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!
Clear change in eneegy levels!
I had originally purchased this product in a local store but found that Amazon had a better price and, of course, door-to-door delivery. So far I am hooked! I feel a noticeable increase in energy when I take these pills and when I forget, I also dragged through the day. Each of the vitamins are inactive form and of high quality so my body does not have to convert anything before its in usable form. The only thing I would recommend is to make sure you take this with a meal. I do notice nausea if I take it on an empty stomach but as long as you eat breakfast in the morning this should never be an issue. Thank you so much for making a high-quality product. I have tried others and this is by far the best!
Best Types of Bs
These B Complex capsules have the best types of Bs (i.e. folinic acid instead of folic acid). Definitely recommend. Im a “researcher” and I was so happy to finally find one that did.
