L-Methylfolate

Formulated with the Bloodstream-Ready Form of Vitamin B9

Methylfolate is the most metabolically active and bloodstream-ready form of Folate or Folic Acid (vitamin B9). It is immediately absorbed into the bloodstream because it does not require processing or breakdown by the body. This is crucial for those with methylation issues that cannot properly process folic acid.

Full Spectrum B12

Contains the 3 Essential BioActive Forms of B12

Methylcobalamin B12
The Essential Form

Supports overall B12 status and essential functions by delivering the most bioactive form found in the bloodstream.

Adenosylcobalamin B12
The energy form

Boosts cellular energy by powering mitochondria for efficient food-to-energy conversion and metabolic support.

Hydroxocobalamin B12
The storage form

Provides long-lasting B12 reserves by staying in the bloodstream longer, ensuring sustained distribution and aiding detoxification.

The Superior Vitamin B1, BenfoPure® Benfotiamine

BenfoPure® Benfotiamine delivers up to 500% better results than standard thiamine. Its unique fat-soluble structure allows it to be ab-sorbed more effectively, delivering vitamin B1 directly to where it's needed your brain, nerves, and muscles. This advanced form ensures higher levels of active B1 inside your cells, maximizing support for energy, nerve health, and overall function.

The Superior Form of Vitamin B5, Pantesin® Pantethine

Pantesin® Pantethine has been shown in research to provide up to 200% greater bioavailability than pantothenic acid¹. As the active form of vitamin B5, it is readily absorbed without extra conversion steps. Pantesin® supports healthy cholesterol metabolism, energy production, and overall heart and metabolic function.*

I just want to say what a great employee you have , Fortune, I was an upset customer who had bought your B- complex liquid before, and ordered it through Amazon, I received an empty package , by the way I’m a retired firefighter, 69 years old, not to good at tech, I got pissed and cussed your company and hung up on him, he called right back and walked me through email, the whole process, and is sending a replacement bottle. Great guy , don’t know if they’re all like him but he deserves a raise and promotion to training. Thank him again for me .
Sincerely Bille Sheppard

Difficulty Taking B’s

If you have difficulty taking b vitamins because of the smell, taste or hate taking pills. You will love this B vitamin it’s mild tasting and you can easily mix it into juice or drink it directly. My 16 year old needs b vitamins and I’ve had the hardest time getting her to take them until I received this product. We’ve tried everything even chewable which was awful. This is mild tasting and slightly sweet berry taste. I love That it comes with a measuring cup. It’s a higher quality product because of the 3 different forms and ability to get into bloodstream effectively. I really Love it!

Blood work showed I was low on B6 and B12. Wanted something made in USA, something not just from the drug store and something I felt I could trust. I haven’t had any follow up blood work but I do know this stuff must be good because it tastes terrible!

It Really Works

I have had neuropathy for at least 20 years and it was getting so bad I had trouble feeling my left foot. This caused me to be unbalanced, stumbling, sometimes falling. Then I read an article about a percentage of the population not being able to absorb the benefits of B vitamins through the normal digestive process, and how they can solve this problem by taking liquid B vitamins under the tongue.

So I did some research and decided to try the Triquetra brand of liquid B Complex. And I am so happy I did! The neuropathy in my right foot is gone completely and the neuropathy in my left foot has greatly improved. My left foot likely has some permanent damage since it was always the worst, but at least I can feel my toes again and I have regained most of my balance.

I wish my doctors had given me this information 20 years ago... even ten years ago would have made a huge difference.

The best methylated B complex

I’ve tried a number of methylated b complex. This one by far works the best with my body. I don’t have electric yellow urine after taking it. My energy levels have increased, my hair is growing back in. I would highly recommend this liquid version of the product.

Bioactive vitamin B complex

First and foremost I love this company and their products. As a gastric bypass patient I’ve struggled with vitamins and my labs always showed I was deficient in something. Especially last year when I had my yearly work up. Two weeks ago I went and did my yearly labs for my doctor and last Friday I got my results and my doctor said that my labs were phenomenal. I’m no longer anemic everything was amazing especially compared to last year he asked me what I was doing and taking so I pulled up Triquetra shop and showed him exactly what I was taking and he said for me to keep up the good work and that their products are working for me. What I love about the bioactive b complex is it’s the liquid a couple of droppers and it taste amazing and i go about my day. Because of Triquetra I’m no longer struggling with my vitamin intake

Impressed so far...

I have had neuropathy in my feet for nearly 20 years. The pain, the burning, the numbness, the cold toes that feel like cubes of ice have kept me from having a decent night's sleep for at least 15 of those years. And more recently my hands have started to tingle, my ankles have started to feel stiff.

Then I happened across an article that touted the benefits of sublingual B Complex (specifically B1, B6, B12) vitamins on reversing neuropathy. I did a little Dr. Google research which verified the claims in the article, so I went looking for the specific formulas mentioned in the article and found theBioActive Vitamin B Complex Liquid formula checked all the boxes. The price point was not excessive as expected, so I bought my first bottle

After the first three days taking BioActive Vitamin B Complex Liquid I noticed my hands weren't feeling as stiff or tingly as they had been. Next I noticed my right foot was feeling pretty normal again. My left foot, which was always the worst, has improved. I can feel the "blocks of ice" that are my toes melting, the foot isn't as numb any more. But most important, the burning is totally gone after 16 days and I have been sleeping... really sleeping... restfully for the first time in years. It's no longer a struggle to even fall asleep, let alone stay asleep. I highly recommend this product for neuropathy sufferers and I can't wait to see what happens with continued use.

Clogs in dropper

Trying to unclog the dropper every day to use it is ridiculous. After this bottle is used up, we will be looking for a different option.

Awful taste

Have only taken once because the taste is absolutely awful. The other B-12 liquid I get from Walgreens tastes much better.

B complex

It exceeds my preconceived notions. Your b complex works greatly that I can reduce the dosage, and still reap benefits. Besides your b complex, I'm thinking that all your supplements function really well. I'm new, so let me take a look around, do research and I'm certain to get another.

Tastes like flintstones kids vitamins and I can’t get over it

Products color is a reddish orange, and the taste is awful. I had a bad experience as a kid having to eat the flintstones vitamins everyday and these taste just like that. I had to make a point to take this first before my other vitamins or I wouldn’t take it at all. It’s the worst part of my day. Now I’ve stopped taking all my vitamins all together because I always put off taking this b-complex. It’s really so horrible and brings back all the bad memories from childhood. I regret buying this liquid form and wish I would have just stuck with the capsules…
