This supplement contains no fillers of any kind and is made up of 81% Thiamine in total.


Most of the main vitamins can never be consumed at high enough levels to actually warrant any kind of toxicity concern. However, excessive drinking, poor diet or liver problems may lead to a deficiency of Thiamine. Those who suffer from Thiamine deficiency may have symptoms such as gastrointestinal discomfort, indigestion, leg cramps, insomnia, muscle weakness, exhaustion, weight loss, constipation, irregular heartbeat and irritation. It may even disturb the flow of HCL production in the body, causing further digestion problems.


This supplement comes in the form of a crystalline powder with a slightly off-white or almost yellow hue. If the water is warm or hot, this supplement will dissolve easily. It may also be mixed with juice. B vitamins are known for working well with other B vitamins, so it may be best to take some Vitamin B2 and Vitamin B6 along with this supplement in order to maximize their effects.

Anyone that takes diuretic drinks such as alcohol or sodas should look into taking this supplement, as diuretics cause Vitamin B1 to be expelled from the bladder faster than normal. This product should be stored in an area that is free from light, heat and moisture in order to preserve potency and prevent degradation.

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.*
