There are a variety of other uses for Vitamin B1. It keeps all metabolic functions in the body running smoothly and correctly. It keeps the cardiovascular system running in good health and makes sure that the rate of your heart beat stays regular. The nervous system as well as cognitive systems would not be nearly as functional without a good dose of Vitamin B1 consistently running through the veins.

This supplement comes in the form of a crystalline powder with a slightly off-white or almost yellow hue. Thiamine is easily soluble in water and because the body is constantly cycling it out through the urinary tract, it needs to continually be replaced through diet or supplementation. This substance reacts easily to heat and alkali when these components are added to the solution. Because the vitamin is so popular and so necessary to sustain life it can be found in an abundance of different natural foods, however a synthetic man-made version is also available for purchase. Some of the richer sources of Vitamin B1 include oranges, sunflower seeds, asparagus, baked potatoes, raisins, various meats, beef and organ meats, wheat bread, and brown rice and fortified cereals just to name a few.

There are several types of natural Thiamine phosphate that can be found naturally, and this form is mainly utilized due to its ability to aid transportation throughout the body. The derivatives of this principle Thiamine can mainly be synthesized through various reactions in the body, and each for goes on to assist with other functions in the body such as metabolism of various nutrients, fats, carbohydrates etc. These forms of Thiamine act as a co-factor to many enzymatic reactions that are deemed necessary in order to keep the body working correctly. Thiamine forms new blood when needed and also keeps enough neurotransmitters firing regularly that it keeps the brain alert and well stimulated. It has a mostly beneficial effect on just about everything from general cognitive ability to a healthy appetite, to production of hormones and energy, etc.

As far as bodily locations of Thiamine are concerned, the largest deposits of this vitamin are located in the most important organs of the body including the liver, kidneys, heart, and brain; however they do also collect in the muscles.

The name Vitamin B1 was given to Thiamine not because it was the first vitamin to have ever been discovered, but because it was the first to have been classified in a group of what we now refer to as vitamins. A healthy diet will have large amounts of Vitamin B1 present in it and this diet needs to take into account a large portion of Vitamin B1 on a daily basis since it is so often expelled through the urine. This is possibly the best reason to supplement, because it makes scheduling servings of Vitamin B1 so much easier rather than having to worry whether one food has it or not. The body does not routinely store Vitamin B1 anywhere so this is why it is best to take multiple servings per day.

Health Benefits Provided by Thiamine

As stated above, it would be impossible for metabolism to occur without the presence of Thiamine. This goes for most types of metabolism including the main kind, metabolism of proteins, fats, and carbohydrates in the interest of using them as energy. Vitamin B1 is essential in the production of ATP which the body needs in order to store energy for later if a very trying exercise were to occur or for that matter, if any physical activity is necessary at all.

Vitamin B1 has a strong effect on the way that blood is formed. It also protects the kidneys, liver heart, circulatory system, brain, and digestive system safe and intact, free of pain or misery while at the same time regulating growth in the body and certain hormonal secretions. Thiamine has antioxidant properties which allow it to keep the body free from damage by harmful free radicals.

helpful to my health

I am re-ordering this vitamin B1 as it's working well with other B vitamins for my energy daily, really gives a power boost in early afternoon, mixed with orange drink and swished in the mouth to absorb better. In my one year with Bulk Supplements, I really appreciate the outstanding rapid service as well as excellent products!


I wish I had known about this years ago !!!

Glad to finally have hope in healing the root cause of migraines! So far I seem to have fewer and the ones I do get seem less in severity. As always product seems high quality, fast shipping and great customer service !!


Great Product

I love this product. I have been putting it in my morning smoothie. I have more energy each morning. I would definitely purchase again!


Thiamine HCL B1

This product is very good, I drink alcohol quite a bit and this has been helping me to rid the lower leg muscle cramps and has been making me feel like drinking a lot less. Would recommend to anyone trying to cut back on drinking while maintaining thiamine levels. I had been taking thiamine mononitrate and it doesn't work, this product works for me very well.
