It works and is worth putting up with the taste
This is an excellent quality product. It is so effective that I put it on monthly autoship. The taste varies from bottle to bottle and sometimes pill to pill, and it does take some getting used to. I can understand why some people find the taste awful, but for me it is well worth dealing with the taste. It has minimal ingredients, it absorbs quickly under your tongue, so it is easy to swallow. It does contain a tiny amount of dairy.

BAD TASTING

TASTES DISGUSTING! DO NOT BUY! THROWING IT IN THE GARBAGE.
I read the reviews and should have listened. I have a strong tolerance with taste if it is something I know is good for me, but I could NEVER get this down! I cannot believe how truly AWFUL it tastes. Pretty unhappy, especially since Amazon's return policy prevents me from returning. Do not make the same mistake I made. Find something else this is unbelievably horrible!

Horrible taste, but dissolves very fast!
I haven't had time to see if they're effective or not, so just rating based on taste etc. These things taste SO bad, but I take them along with my dissolvable CoQ10 that's fruity so it takes the bitter away for the most part. They melt super fast so it's only bad for about 10 seconds.

Not for the Weak
*Please read the whole thing* These comments are not exaggerating. I cannot tolerate pills so I have cut every medicine imaginable in half. This was by far the worst tasting med I've ever had. But I got used to it! At first I quite literally had to eat a mint after taking this tablet, but a month later I don't even notice it. It's become apart of my daily routine I used to wake up exhausted, could barely get out of bed, dizzy during the day and had to take naps or drink multiple cups of coffee. Now I'm waking up well rested and I have more energy. If I go a week without taking these vitamins, I notice! This stuff is the real deal. Life changing

It really does taste bad..
I thought reviews about the taste were being dramatic... Nope, it tastes nasty. Absolutely horrible and it sticks with you. We use other dissolve vitamins in this brand that are totally fine and we consistently buy and use. I want the benefits of this one but I'm not sure I can handle this flavor. It dissolved quickly. Next time, I will try placing it under my tongue to see if that helps. I don't know if I can recommend it though. The flavor taste like you chewed a multi vitamin that was supposed to be swallowed only but it melts in your mouth :-/ Icky.

Bitter but works wonderfully
I originally gave it 3 stars due to bitter taste but the benefits outweigh it, plus you get used to the taste in a day or two. The first day of taking it, I noticed an increase in energy. The second day of taking it, the mood also improved ten fold. Cannot wait to see what happens in a week!

For my cat with seizures caused by possible thiamine deficiency
I have a 14-15 year old cat that developed seizures after getting a convenia shot this past winter, being on an rx kibble for struvites, and metronidazole for a c.perfringens infection over the winter and spring. Both drugs and the d-methionine in the kibble to lower urine ph lower the seizure threshold. It wasn't until he was given just two doses of the metronidazole that the seizures manifested clearly and scarily ~ tonic clonic aka grand mal seizures. Looking back to the winter his symptoms appear to be seizures. Seizure meds have helped for the most part but he's still having too many periods of him looking out of it and lost and walking around in circles which point to absent seizures aka petit mal seizures. He's on a keto diet with MCT oil to help with the seizures but we just started the MCT oil about 3 weeks ago. We've added homeopathic remedies and an herbal remedy for pets specifically for seizures which bring him out of it for a while. My daughter who spends the majority of time with him has been researching (as have I) and stumbled across a case study of two cats presenting with seizures due to thiamine deficiency. Both recovered quickly after B1 injections. As well as another article written by a woman who suffers from metronidazole toxicity and found that she had a thiamine deficiency that contributed greatly to her symptoms, one of which was a slightly enlarged heart (the vet has detected a grade 1-2 murmur which is also a thiamine deficiency symptom). So I got this to give it a try. We are starting at a lower cat-sized dose since he appears to be sensitive to everything. I cannot even give him CoQ10 for his heart since it triggers seizures. Anyways we're on day 2 of supplementing so too soon to tell if it's helping. I dissolved a couple of tablets in water in 10 mls of water in a small brown glass bottle and keep in the fridge. To dose him I pull the amount I want (this morning was 25mg ~ so 1.5ml) into a dosing syringe and squirt it down his throat. He doesn't seem to mind it. I guess he's gotten used to all the supplements we've been giving him. I also got the b-complex by the same company for kids to make sure he's not getting depleted in the other b's. I just put the tablet in a dosing syringe and pull in a mil or two of water to squirt down his throat so it's over quick. So people who are having problems getting past the bitterness or taste of the b100, they can try what we've been doing. Dissolve the tablet in a small amount of water (1 teaspoon or less) and then hold your breath and put it in your mouth and let it absorb into your mouth. Holding your breath will help blunt the taste. Follow up with a sip of water.

Parkinson’s disease
These tablets are bitter to dislove under the tongue but they are easy to get used to.

Vitamin B1 is good for Parkinson's patients.
Vitamin B1 is effective to tackle jerking body, quivering mouth and tightening of toe muscles. For my case I usually take 2 tablets each time, once a week. There are times, seldom, I take 2 tablets each time twice a week. Only take when acute symptoms appear.

Totally love this product.
My husband is using these to help stop his early Parkinson's symptom of shaking hands. It has worked extremely well.
