Key takeaways
- Thiamine, also called vitamin B1, is one of the 8 B-complex vitamins and is classified as a water-soluble B vitamin. The body needs it to turn foods into energy, which matters for the growth, development and function of cells.
- Only small amounts are stored in the liver, so a daily intake of thiamin-rich foods is needed. Because thiamine is stored briefly then excreted rapidly, keeping adequate blood serum levels requires consistent, regular dietary intake.
- We publish our B1 as thiamine nitrate at 1.23 mg per gram, which is 12.3 mg in the 10 g daily serve.
- B1 works as part of a single balanced daily dose, not a collection of separate supplements. The value sits in how the ingredients work together.
- One 10 g scoop in cold water each morning. You can take it with or without food.
What is vitamin B1, and what does thiamine do?
Vitamin B1 is a water-soluble vitamin that helps your body convert what you eat into energy your cells can actually use.
Thiamine, also known as thiamin and vitamin B1, is one of the 8 B-complex vitamins and is classified as a water-soluble B vitamin. It is a water-soluble substance that occurs in free or phosphorylated forms in most plant and animal tissue. It is found naturally in some foods, added to foods, and sold as a supplement. In medical terms, thiamine sits in a class of medications called vitamins.
Think of B1 as part of the ignition system rather than the fuel. Food goes in, and thiamine helps the machinery convert it. It plays an essential role in the supply of energy to the tissue, in carbohydrate metabolism and in the metabolic links between carbohydrate, protein and fat metabolism. It is needed by the body to turn foods into energy, which is important for the growth, development and function of cells. Thiamin also plays a vital role in the growth and function of various cells.
Where does vitamin B1 fit in a day that runs on coffee and stress?
B1 fits into the daily maintenance layer of your energy, the part that keeps working while caffeine does the loud stuff.
Wired but tired is a real pattern, and it usually means the body is being pushed rather than supplied. Energy should feel bright, not frantic. That is the difference between stimulation and steady fuel.
Because B1 is water-soluble and not stored in the body long-term, taking it in supports normal vitamin B1 levels. Only small amounts are stored in the liver, so a daily intake of thiamin-rich foods is needed. Thiamine's limited storage duration before rapid excretion means maintaining adequate blood serum levels requires a consistent and regular dietary intake.
That is why B1 belongs in a daily ritual rather than an occasional top-up. In Hoola it also sits behind one of our listed uses: helping prevent dietary vitamin and mineral deficiency.
Which form of vitamin B1 is in Hoola, and how much do you get?
Hoola uses thiamine nitrate at 1.23 mg per gram, which is 12.3 mg in the 10 g daily serve.
Every per-serve figure is the per-gram figure times ten. Both are published. The certificate lists all 27 active ingredients with exact quantities per gram, and anyone can look up AUST L 508472 on the public ARTG register and check every number. No proprietary blends. We provide full formula transparency, including dosages of all functional ingredients, with nothing to hide.
For context on dosing, multivitamins supplement an additional 1.5 mg of thiamine to a diet already abundant in this essential vitamin. If intake is high, only a small amount of the thiamin is absorbed, and elevated serum values result in active urinary excretion. Our approach is your daily essentials, no mega doses, just smart daily support.
Why did we choose thiamine nitrate over other B1 forms?
We chose thiamine nitrate because it suits a stable daily powder that you mix fresh each morning, and it sits inside a formula built on active and bioavailable forms wherever possible, in line with Australian quality manufacturing standards.
B1 turns up in several forms across the market. Some products use thiamine hydrochloride as the active ingredient. Thiamine Hydrochloride 100 mg in 2 mL Injection is one clinical form of vitamin B1. Oral thiamine comes as standard and slow-release tablets. Supplements are also available alone and in combination with other vitamins.
Across the B-complex we use pyridoxal 5-phosphate (B6), levomefolate (folate), mecobalamin (B12) and riboflavin sodium phosphate (B2), so they are ready for the body to use without additional conversion steps. That is the same thinking behind our minerals: bioavailable forms your body can actually use, because minerals should work with you rather than pass through you. Expert formulation with meaningful dosages, tiny team, major impact.
How does vitamin B1 work with the other 26 actives?
B1 works as one part of a single balanced daily dose, and its job overlaps with several others in the scoop.
Like other B vitamins, thiamine is essential for the metabolism of proteins, carbohydrates and fats, which the body turns into energy. In Hoola, B1 sits alongside calcium pantothenate (B5) with the same listed use: support normal energy metabolism and the conversion of food into usable energy. Our active B-complex also supports the nervous system, supports healthy red blood cell formation (B6, B12, folate), supports cognitive performance, and supports healthy skin, hair and nails (biotin, B2, B3).
Then the herbs pick up the parts vitamins cannot. Cordyceps supports natural energy production and helps reduce occasional tiredness and fatigue. Korean ginseng supports natural energy levels and stamina. KSM-66 Ashwagandha helps support the body's natural stress response. Reishi supports healthy sleep patterns and relaxation without sedation. Bacopa supports memory, recall and retention, and enXtra supports mental alertness, attention and sustained focus.
Hoola is designed as a single, balanced daily dose, not a collection of separate supplements. The value sits in how the ingredients work together to maintain and support energy production. Living brighter, with balance, energy and a mind that feels clear, steady and ready for whatever comes next.
Who tends to look for a vitamin B1 supplement?
People whose energy feels inconsistent, and people whose diet or lifestyle puts extra demand on their B vitamins.
Thiamine (vitamin B1) is used as a dietary supplement when the amount of thiamine in the diet is not enough. It occurs naturally in specific diets, is added to food products, and is available in dietary supplements. Where you live matters too: there is mandatory thiamin enrichment of baking flour in Australia but not in New Zealand. Alcohol is another factor, since the normal metabolism of alcohol in your liver requires B vitamins, especially thiamine.
Then there is the group we built Hoola for. People juggling work, workouts, to-do lists and everything else, who want more energy, more clarity and more stability without feeling wired, anxious or overwhelmed. Hoola is built around one duality, calm clarity and energised performance, for people dealing with burnout, emotional load, stress and the need for energy that lasts.
How should you take vitamin B1 each day?
Mix one 10 g scoop into 300-400 ml of cold water each morning.
There is no half serve, no double serve and no weekly total. Hoola is one 10 g scoop a day. Take it in the morning or early afternoon, and avoid it close to bedtime because of the caffeine.
Food is optional. Absorption does not differ from supplements given with breakfast or on an empty stomach. You can take it with or without food.
Consistency beats intensity here. Most of our customers feel the biggest benefits with consistency. We imagine a future where your best energy is not reserved for weekends or holidays but shows up with you every morning, where you can pour into others because you are already full, and where science and nature lift you gently rather than jolt you forward. One scoop. Steady energy. All day. You can see the full formula here.
Frequently asked questions
Which forms does vitamin B1 come in?
Hoola uses thiamine nitrate at 1.23 mg per gram, which is 12.3 mg per 10 g serve. Elsewhere you will find thiamine hydrochloride, including Thiamine Hydrochloride 100 mg in 2 mL Injection, which contains that active ingredient. B1 also appears inside vitamin B complex tablets and multivitamin tablets where thiamine is listed as an ingredient.
Can you take vitamin B1 every day?
Yes. Only small amounts are stored in the liver, so a daily intake of thiamin-rich foods is needed. With Hoola there is no half serve, no double serve and no weekly total. It is one 10 g scoop a day.
What does vitamin B1 support in the body?
Energy metabolism first. Vitamin B1 (thiamine) is a water-soluble vitamin required for protein, carbohydrate and fat metabolism, which the body converts into energy. It may also assist with the synthesis of neurotransmitters to help support nervous system function and health. In Hoola, B1 is listed to support normal energy metabolism and the conversion of food into usable energy.
How much vitamin B1 do adult supplements usually provide?
Multivitamins supplement an additional 1.5 mg of thiamine to a diet already abundant in this essential vitamin. For scale, the total body content of the vitamin is about 30 mg. Hoola provides 12.3 mg of thiamine nitrate in the 10 g daily serve.
Which foods contain vitamin B1?
Cereal foods lead. Thiamin is found predominantly in cereal foods. There is also mandatory thiamin enrichment of baking flour in Australia but not in New Zealand.
Do any fruits contain vitamin B1?
Yes. Vitamin B1 is found in foods such as beef, oats, eggs, seeds, legumes, brown rice and oranges.
Is there such a thing as a natural vitamin B1 supplement?
Thiamine occurs naturally in specific diets, is added to food products, and is available in dietary supplements. So the same vitamin reaches you through all three routes. What matters more is the form. Hoola uses active and bioavailable forms wherever possible, in line with Australian quality manufacturing standards, and lists B1 as thiamine nitrate at 1.23 mg/g.
What is a thiamine supplement, and where do you get one?
A thiamine supplement supplies vitamin B1, an essential water-soluble vitamin required by the body to ensure that all its tissues function properly. You can buy thiamine supplements from pharmacies or shops. In Hoola it arrives as part of a 27-active daily scoop rather than a standalone tablet.
Is Hoola's vitamin B1 suitable for vegans?
Yes. Hoola is vegan, with no sugar, gluten free, naturally flavoured and no artificial fillers. We use Vitashine vegan vitamin D3 and Lyc-O-Beta plant-source beta-carotene.
Is Hoola built for ongoing daily use?
Yes. Thiamine's limited storage duration before rapid excretion means maintaining adequate blood serum levels requires a consistent and regular dietary intake. The herbal side takes its own time, and adaptogens may take 4-6 weeks for their full benefits. The 150 g pouch is two weeks, so you can start there and see how you feel. More on the ingredients and the ritual sits on our blog.
Always read the label and follow directions for use.
