You wake up heavy. Coffee before the first email. Another by eleven. The 3pm slump lands on schedule, and by bedtime your head is still buzzing. Under all of that sits a very ordinary question about fuel: your cells have to turn what you ate into energy you can actually use, and they need specific tools to do it. One of those tools is vitamin B1.
Vitamin B1, also called thiamine, is a water-soluble B vitamin your cells use to convert the carbohydrates you eat into usable energy, and it is also needed for normal nerve, muscle and heart function. It is one of eight B vitamins , found naturally in some foods, added to others, and sold as a supplement . Your body needs it to make adenosine triphosphate, or ATP , the form all your cells use to store energy .
That is the kind of steady, unglamorous work we build Hoola around. Energy without the edge. A 10 g Hoola serve delivers 12.3 mg of thiamine nitrate, and you can check that number yourself on the public ARTG listing.
Key takeaways
- Vitamin B1 and thiamine are two names for the same nutrient: one of eight B vitamins , water-soluble, found naturally in some foods, added to some foods and sold as a supplement .
- Its main jobs are glucose metabolism and nerve, muscle and heart function , and it is essential for normal nerve and heart function .
- Thiamine works as a coenzyme in the metabolism of carbohydrates, fats and proteins , and your body needs it to make the ATP every cell stores energy as .
- A 10 g Hoola serve delivers 12.3 mg of thiamine nitrate, and every quantity sits on the public ARTG listing under AUST L 508472.
- Humans store thiamin in the liver in very small amounts , and heating, cooking, processing and boiling foods in water destroys it , so intake needs to be regular.
What is vitamin B1, and why is it also called thiamine?
They are the same nutrient with two names. Vitamin B1 is thiamine, sometimes spelled thiamin, and it is one of eight B vitamins . Like every vitamin in the B complex, it is water-soluble .
It turns up in plenty of ordinary food. Thiamine is commonly found in many plant and animal-derived foods , it is added to some food products, and it is available as a dietary supplement . In the body it exists in a free form as thiamine, or as a mono-, di- or triphosphate .
The double naming is a quirk of history, not a difference in chemistry (the "thiamin" spelling on a nutrition label is the same molecule as the "vitamin B1" on a supplement panel). Thiamine has a multidirectional action on the human body and has long held the interest of doctors, nutritionists and scientists .
What is vitamin B1 good for in everyday energy and focus?
It is one of the eight B vitamins that aid in the production of energy , and it is essential for glucose metabolism and nerve, muscle and heart function .
Modern life does not hand out quiet mornings. Your calendar is stacked, your brain is buffering, and the fuel system underneath still has to keep running. Thiamine is part of that system in more than one place. It is essential for normal nerve and heart function . It is needed for the proper functioning of the central and peripheral nervous system, where it is involved in neurotransmitter synthesis . It plays a role in healthy liver function and is needed for healthy skin, eyes, hair and nails . It also plays an important role in the production of red blood cells, which are used for ongoing energy .
Because of its high biological activity and its role as an enzyme cofactor, thiamine has both direct and indirect effects on cell metabolism . Some experts call vitamin B1 the anti-stress vitamin, because it helps your body cope during stressful situations .
That is the state we design for. Not doing more. Operating better. Calm clarity, energised performance, a brighter way to live every day.
How does thiamine turn the food you eat into usable energy?
It acts as a coenzyme. Thiamine plays a special role in the body as a coenzyme necessary for the metabolism of carbohydrates, fats and proteins . Enzymes do the work in the body, and B1 is involved in five different enzymes .
Follow a meal through. Vitamin B1 helps break down the food you eat and converts it into energy , and carbohydrates in particular . It enables the body to use carbohydrates as energy . It also participates in energy production in the mitochondria and in protein synthesis . Your body then needs thiamine to make ATP , which all the cells in your body use to store energy .
Think of thiamine as the key that fits the ignition rather than the petrol itself. The vitamin plays a critical role in energy metabolism and, therefore, in the growth, development and function of cells . When you eat thiamine-rich foods, they help the body convert carbohydrates to energy, which matters for your metabolism, focus and overall strength .
Energy should feel bright, not frantic. No jitter, no crash, just cells doing their job properly.

Thiamine does not work alone in there. Hoola is designed as a single, balanced daily dose rather than a shelf of separate supplements, and the value sits in how the ingredients work together. Built in Australia and backed by science, it blends modern nutrition with nature's brightest ingredients to support the dual state most of us want: calm clarity plus energised capability.
How do you get enough vitamin B1 day to day?
Regularly, and from a mix of food and supplementation, because your body cannot make thiamine on its own and cannot hold much of it either.
Thiamine, like all B vitamins, is water-soluble , which means it dissolves in water and cannot be stored in your body . Humans store thiamin primarily in the liver, and only in very small amounts . Water-soluble vitamins travel through the bloodstream , thiamine breaks down rapidly once consumed and is flushed from the body more easily than fat-soluble vitamins, which can accumulate , and your body flushes out any excess in your urine .
Cooking takes a cut too. Heating, cooking, processing and boiling foods in water destroys thiamin , and because vitamin B1 is water-soluble it dissolves into the cooking water . Ingested thiamin from food and dietary supplements is absorbed by the small intestine through active transport at nutritional doses and by passive diffusion at pharmacologic doses . Vitamin C lowers the pH in your gut, which enhances the absorption of thiamine , and Hoola carries 112.1 mg of magnesium ascorbate monohydrate as a vitamin C source in every 10 g serve. Thiamine supplements are also available from pharmacies and shops .
Our approach to vitamins is simple: daily essentials, no mega doses, smart support you actually repeat. Living brighter means balance, energy and a mind that feels clear, steady and ready for what is next. Mix one 10 g scoop into 300 to 400 ml of cold water each morning. Consistency beats intensity, and most of our customers feel the biggest benefits with consistency. More on how the blend fits together sits on the Hoola blog.
One scoop. One glass of cold water. One less thing to think about.
Frequently asked questions
Is thiamine the same thing as vitamin B1?
Yes. Thiamine, also spelled thiamin, is vitamin B1, one of the B vitamins . The number comes from the order of discovery: researchers found this B-complex vitamin first, hence the name B1 .
What are the benefits of vitamin B1?
Vitamin B1 has several benefits, including support for energy production . It is involved in many of the most important metabolic processes of the body . Because thiamine and other B vitamins are naturally energising and required to produce ATP from foods, B complex supplements are often sold under energy and healthy metabolism labelling .
Do you need vitamin B1 every day?
Yes. Humans need a continuous supply of vitamin B1 because the body does not store it . Only small amounts are held in the liver, so a daily intake of thiamin-rich foods is needed , and if the body does not use the vitamins, it excretes them in urine .
How much vitamin B1 do adults need each day?
The National Institutes of Health suggests adult males typically require 1.2 milligrams and adult females typically require 1.1 mg .
Which foods are high in vitamin B1?
Fish and pork are especially high in thiamine , and most foods are a good source of it . Most high-protein foods provide some thiamine, plus other B vitamins like B12 and B6 . In the United States, people get around half of their vitamin B1 intake from foods that naturally contain thiamin, with the rest coming from fortified foods .
Is vitamin B1 any different for men?
The nutrient is identical; the daily amount can differ. Daily vitamin B1 intake requirements may depend on someone's age and sex , and the NIH figure for adult males is 1.2 mg . Like the other B vitamins, B1 is an essential nutrient that helps your body's cells grow, develop and function .
Is vitamin B1 any different for women?
The nutrient is identical here too, with a slightly lower daily figure: the NIH suggests 1.1 mg for adult females . Thiamin plays a vital role in the growth and function of various cells , and thiamine is a vitamin necessary for proper cell function . Every 10 g Hoola serve carries the same 12.3 mg of thiamine nitrate, whoever is holding the scoop.
