Vitamin B1 (Thiamin) Benefits and Uses

  • Nothing but active ingredients
  • Helps maintain energy level*
  • Supports nervous system function*
  • Promotes proper heart function*

Vitamin B1, also known as thiamine, was one of the first organic compounds to be recognized as a vitamin. Like all the other B complex vitamins, it is water soluble and not stored in the body. Rather, excess amounts of B1 will be excreted. And like the other B vitamins, it helps the body convert the foods we eat into usable fuel to maintain life-sustaining functions.

Vitamin B1 must be in adequate supply for aerobic energy production to take place. This is the process in which sugar (glucose) is converted into usable energy.

Vitamin B1 also plays roles in the nervous system. It promotes the healthy development of myelin sheaths, the material that surrounds and protects most nerves. Insufficient vitamin B1 intake can result in degradation and damage to the myelin sheath. Symptoms such as pain, prickly sensation, and deadened nerves may be linked to a vitamin B1 deficiency.*

Thiamine is needed for the production of acetylcholine, a neurotransmitter that relays messages between the nerves and the muscles. Acetylcholine’s importance in maintaining muscle tone makes vitamin B1 a significant nutrient in maintaining proper heart function because the heart is a muscle whose performance is vital to human life.*

Absorption of vitamin B1 requires sufficient supplies of vitamin B6, B12, and folic acid.

Why Choose Us? With over three decades of unparalleled experience in the health and wellness industry, Dr. Clark Store stands out as a beacon of trust and quality. Unlike others, we are the actual manufacturers who take pride in our craft, overseeing the entire production process to ensure that each bottle meets our high standards. With more than 31 years of expertise and over 10 million bottles produced, you can rest assured that you're choosing a partner dedicated to authentic wellness. We don’t outsource to the lowest bidder.

Guaranteed Authenticity: Every batch of Vitamin B1 is carefully sourced and undergoes rigorous testing for ID, purity, potency, and microbiology before, during, and after manufacturing.

Just Pure Ingredients: At Dr. Clark Store, we stand against adulteration. Our rigorous testing reveals that an estimated 30% of bulk supplement powders in the U.S. market contain added fillers and/or come from incorrect species or plant parts. Unlike importers who operate according to FDA 21 CFR 117 and often rely on analyses done by the manufacturer abroad, we conduct thorough tests on all incoming materials in our full-size laboratory, guaranteeing the integrity of our products.

Carrageenan and Surfactant-Free Capsules: FDA regulation 21 CFR 101.100(a)(3)(ii) allows manufacturers to avoid disclosing ingredients in food if present at “insignificant” levels. This is why "Veggie Capsules" may contain carrageenan. Dr. Clark Store ensures the use of only the finest BSE-free gelatin capsules, free from carrageenan, surfactants, and prion risks. Our dedication to purity dates back over 30 years, ensuring safety and quality in line with Dr. Hulda Clark's original vision.

No Magnesium Stearate and No Hidden Processing Aids: True to Dr. Clark's vision, we never use magnesium stearate or any toxic processing aids in our products. Our commitment to transparency means all ingredients are clearly declared on the label, offering you peace of mind and a product you can trust. Again because of FDA’s lacking regulation 21 CFR 101, many brands contain magnesium stearate without it being declared on the label.

Verifiable GMP Certification: Trust is earned, not given. That's why we back up our GMP certification claims with verifiable evidence. Partnering with VeriGMP®, a UL-certified company, we adhere to strict GMP quality systems, ensuring that each product meets the highest standards of manufacturing and quality assurance.

Choose Dr. Clark Store for your vitamin supplement needs and experience the purity and authenticity that only comes from a legacy of passion and excellence in natural wellness.

Supports Energy Metabolism

Vitamin B1, also known as Thiamin, plays an essential role in converting carbohydrates into energy. It helps your body use glucose, which is crucial for maintaining energy levels throughout the day. When you take Vitamin B1 supplements, you're not only supporting your energy metabolism but also enhancing your overall vitality. This is especially important for individuals with increased energy demands, such as athletes or those with active lifestyles.

Promotes Healthy Nervous System

The importance of Vitamin B1 extends beyond energy. It is vital for the proper functioning of the nervous system. Thiamin helps to maintain healthy nerve function and can enhance cognitive performance. This makes it an important nutrient for students or anyone looking to support their focus and mental clarity. Ensuring adequate levels of Vitamin B1 in your diet can help keep your nervous system functioning optimally.

Supports Heart Health

Vitamin B1 also plays a crucial role in promoting heart health. It contributes to the proper functioning of the heart muscle and helps regulate cardiovascular health. By incorporating Vitamin B1 supplements into your routine, you can support your heart’s health and improve your overall well-being. A healthy heart is essential for maintaining energy levels, managing stress, and living a healthy life.

A Beautiful Timepiece at an Awesome Price!!
Color: Grey, Color: Grey
I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.

Classy and sporty. Great value!
Color: Grey, Color: Grey
Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.

Stunning Gentleman's Watch
Color: Grey
This is my second Tissot watch. It's quite stunning in person. The online photos don't do it justice. It has the look and feel of a much more expensive gentleman's watch which makes this purchase a great bargain. Tissot is a great reliable Swiss made watch brand. My first Tissot watch which is probably more than 20 years old still runs great. Very pleased with this purchase.

Good Tissot Watch
Color: Grey
Arrived on time, in its original box, include a 2 year international warranty, into the box include a book with the Tissot brand history in Switzerland. Algo a second book with a whole catalog of Tissot watches men and women. The watch looks better when you put in on your wrist. The “naval” blue really gives the clock a classy look. The stainless steel workmanship is really good, the metal is bright and perfectly polished. The metal wristband quality is very good, did not have any problem to adjust the size , I went to my preferred clock workshop for this job, they extracted a few pieces of the band to fit to my small wrist size. Have to get used to the butterfly latch, but after a few days, now I learned to open and close it without any effort. The clock it’s very accurate, I’ve been using my Tissot for near a month and it just increased a few seconds per week. I do the setup and check accuracy with my pc clock. In short, It”s a good value watch, nice, good looking, accurate.

Perfect everyday Watch
Color: Grey, Color: Grey
Super happy with this watch. It looks really clean and goes with pretty much anything dress it up or wear it casual. The blue face is fire in person and catches the light really nicely. Feels solid on the wrist, not too heavy, and the quality is definitely there. I’ve been wearing it almost every day and it still looks brand new. For the price, you really can’t beat it. Great everyday watch that looks way more expensive than it is. Would 100% buy again
