Review: 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.
Review: 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!

### ⭐ Tastes TERRIBLE
*by A***. on October 31, 2024*

These can be swallowed whole, but I purchased this particular one because they are sublingual dissolving tablets, which are supposed to have a higher absorption rate (for those of us that have chronic gastritis) and I wanted to see if I could avoid having to have B1 shots. I can't speak as to their effectiveness because I only tried one and plan to purchase a different brand, but they taste like a horribly bitter pill, like literally dissolving a normal pill in your mouth. It took hours to get the bitter taste out of my mouth. And I'm not being a pansy, I take liquid supplements that do not taste good by any stretch, and they even upset my stomach sometimes. But if you are wanting these to take sublingually, I do not recommend it. There are capsules that are cheaper and higher mg dose if you just want a normal pill to swallow whole.
