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.

Great toy!!!
Style: Original
My dog went mental over this ball!!! She will let me roll it through the backyard or in the house and she will go nuts for it but the great part, she will play by herself with this ball. She will roll it and jump on it and just have a blast. Since this is not a normal chew toy, my dog's big, she only gets it when I'm with her. It kind of makes it our special thing when I pull it out. We play every day with it and her enthusiasm has never lessened. She can be in another room when I take it out of the cabinet and the second she hears it, she will run into walls in her rush to get to me so we can play! It really is better than just throwing a ball back and forth. She's completely engaged the entire time it's out. I highly recommend it but just know it's not a normal toy that you can just throw to your dog and walk away. It is an amazing toy to help you bond with your pet.

Great for dogs that need to stay busy
Style: Original
My dog absolutely loves this ball. It is a little noisy so we take it out in the yard and let her play with it there. I highly recommend it if you have a dog that get bored easily. This will surely keep them busy.

Fun for the Dogs and Kids
Style: Original
My dog seems to love this ball. Super sturdy for an aggressive chewer. Easy to play with. Makes the tube sound when it rolls which keeps the dogs attention well. Super fun. It’s made out of hard plastic so it’s not soft at all. Can take this anywhere.

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off. One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again. If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.
