Purchased this product to support thyroid, good product. Great price!

Your pet's food is deficient in this vitamin, so add it to your pet's food

I read that the pet food we feed our pets is deficient in vitamin B1 so I wanted to get this so I can add a little bit to their wet food everyday.

Finally ... Supplements that Make Sense!

I was always baffled that while supplements are hailed as being "good for you," the supplements that you find at your typical grocer or pharmacy are full of artificial this and artificial that. Many of the choices at your typical health-store are not that much more pure. Then, along came BulkSupplements! Finally ... Supplements that Make Sense! I add this supplement to just about any soft food, and as long as I mix it well, it works out fine -- with a very slight and thus insignificant change to the flavors! However, lately I have found that I have been saving time in the long run and adding convenience by stuffing this supplement into empty capsules. Thank you, BulkSupplements, for doing the right thing!

Thiamin for Clarity

As far as my experience goes thiamin tends to provide some more mental clarity, it's kind of like someone took the fog out of your brain when you take it. I include this as part of my B-Complex routine.
