I'll ask again, Is this gluten free?

And I will say again, there are only three ingredients....biotin, lactose and acacia gum. look them up if you want to know if they are a gluten product.

Is this supplement manufactured in the USA?

If you look on the box (in the pictures to the left of the item), you will see it says made in USA.

Are these gluten free?

There are only three listed ingredients, biotin, lactose (milk) and acacia gum. I know little about gluten, so you be the judge if any of these ingredients are a source of gluten.

Dissolves instantly, great if you hate pills!

The absolute best thing to come along since sliced bread. I have trouble swallowing pills and these dissolve instantly. They have a pleasant mild taste too.

Not very water soluble.

I purchased these tabs because I needed dissolvable Biotin for my birds. I have one bird in particular (a dove) who hasn't gotten enough biotin from his pellets to prevent problems with his feathers. Adding biotin supplement has made a big difference for him. In the past, I've purchased quick dissolve tablets from another company locally, but I couldn't find them online when the store was out of stock. These were reasonably priced and contained more tablets for the price than the other brand. Plus, the bottle and the description claim they are a quick dissolve tablet as well. Unfortunately, these tablets take lot longer to dissolve than the others. I have to wait about 15 minutes for them to dissolve in his water before giving it to him. I tried one by placing it under my tongue and found it took longer than the others to dissolve using that method as well. That being said, the tablet itself contains the same dosage of biotin as our usual product; and you get more for your money. And, even though they didn't dissolve quickly, they eventually did dissolve, so that's why I gave it 4 stars.
