Key takeaways
- Biotin is vitamin B7, a water-soluble B vitamin that helps turn carbohydrates, fats and proteins into usable energy and plays a part in keratin production.
- Hoola contains biotin at 300 mcg per gram, which is 3,000 mcg (3 mg) in the 10 g daily serve. Every figure is published.
- Biotin is water-soluble, so the body passes what it does not need rather than storing it. A measured daily dose does the work.
- Biotin does not sit alone here. It works with B2 and B3 in an active B-complex, inside one balanced daily dose.
- One 10 g scoop in cold water each morning, taken consistently. Skin and nail changes show up over weeks, not days.
What is biotin, and what does it do in the body?
Biotin is vitamin B7, also called vitamin H, a water-soluble vitamin with real reach across the body. It is an essential nutrient, found naturally in some foods and available as a supplement.
Think of it as a translator. Food arrives as carbohydrates, fats and proteins, and biotin plays a crucial role in their metabolism. By assisting that metabolism, it helps convert those nutrients into energy the body can actually use for its physiological processes. The science underneath is enzymatic: biotin is an essential cofactor for enzymes that catalyse metabolic functions.
Then there is the structural side. Biotin is involved in keratin production, the protein your hair, skin and nails are built from. Two jobs, one small vitamin, working quietly on the inside and showing up on the outside.
Where does biotin fit into a day that already feels full?
It fits at the fuel line. Biotin plays an important role in giving you fuel to go about your day, because one of its top benefits is helping convert carbohydrates, fats and proteins into energy.
Energy feels inconsistent for most people. Not broken, just uneven. Big morning, flat afternoon, wired evening. Hoola is a daily wellness drink with nootropics, adaptogens, vitamins and minerals to support energy, focus and mental clarity. Biotin is one part of that, working on energy metabolism while other ingredients handle stress response, alertness and calm.
We built Hoola to support calm clarity, clean energy and emotional steadiness, so you feel bright, capable and ready every day. Waking up with space, not pressure.
How much biotin is in Hoola, and what form is it?
Biotin sits at 300 mcg per gram, which is 3,000 mcg in the 10 g daily serve. That is 3 mg. For scale, a common single-nutrient biotin tablet on the Australian market contains 150 micrograms per film coated tablet.
We are transparent about what is inside. Every ingredient is delivered at a clinically efficacious dose, and every quantity is published. No proprietary blends. Every per-serve figure is the per-gram figure times ten, and both are printed.
Micrograms convert cleanly. Biotin 3,000 mcg = 3 mg. Folate 890 mcg = 0.89 mg. Chromium 400 mcg = 0.4 mg. Potassium iodide 200 mcg = 0.2 mg. Selenomethionine 150 mcg = 0.15 mg. Molybdenum 80 mcg = 0.08 mg. Vitamin B12 50 mcg = 0.05 mg. Vitamin K2 50 mcg = 0.05 mg. Vitamin K1 90 mcg = 0.09 mg. Vitamin D3 25 mcg = 0.025 mg, which is 1,000 IU.
Hoola is a Listed Supplement on the Australian Register of Therapeutic Goods, AUST L 508472, ARTG start date 8 August 2025, sponsor Hoola Australia Pty Ltd. The certificate lists all 27 active ingredients with exact quantities per gram. Anyone can look up AUST L 508472 on the public ARTG register and check every number.
Why is biotin used in this form rather than a mega-dose tablet?
Because more is not the same as better. Biotin is water-soluble, so any excess is usually excreted in the urine rather than stored in the body. Your body does not hang on to more of it than you need. The body is never taking more than it needs, which is why a biotin supplement is usually considered safe to take daily. At recommended doses, biotin is considered safe for most people, and the risk of toxicity from supplements is low.
A very large single-nutrient dose mostly gives you an expensive result at the other end. We do not chase intensity. We support regulated energy, clear thinking and capability that lasts. Not pushing harder, just operating brighter.
Form matters as much as size. Hoola uses active and bioavailable forms wherever possible, in line with Australian quality manufacturing standards, and every ingredient is delivered at a clinically efficacious dosage. A steady 3,000 mcg every morning helps you stay cool, calm and collected, no matter what the day throws at you.
How does biotin work with the rest of the Hoola formula?
Biotin works as part of a team, not as a solo act. Hoola is designed as a single, balanced daily dose, not a collection of separate supplements, and the value sits in how the ingredients work together.
The skin, hair and nails claim belongs to three nutrients at once: biotin, B2 and B3. That is 3,000 mcg of biotin, 13.7 mg of riboflavin sodium phosphate and 30 mg of nicotinamide in every serve. Zinc joins in from another angle, supporting immune function, skin health, taste and smell.
Then there is the wider active B-complex, which supports normal energy metabolism and the conversion of food into usable energy, supports the nervous system, supports healthy red blood cell formation through B6, B12 and folate, supports cognitive performance and supports healthy skin, hair and nails through biotin, B2 and B3. We use active B forms, pyridoxal 5-phosphate for B6, levomefolate for folate, mecobalamin for B12 and riboflavin sodium phosphate for B2, so they are ready for the body to use without additional conversion steps.
Where a traditional supplement lifts calm or energy on its own, Hoola blends TGA listed nutrients, nootropics and adaptogens to support the dual state modern life asks for. It is a streamlined 27-ingredient formula for everyday performance, while IM8 takes an extensive 90-ingredient whole-body approach. Small nutrients, big jobs, quietly done.
Who tends to look for biotin in the first place?
People chasing better hair, skin and nails, mostly. Biotin is commonly taken for its perceived beauty benefits. That is the usual door in, and the energy metabolism side turns out to be the bonus nobody expected.
The nutrient itself is not hard to find in food. Biotin occurs naturally in eggs, nuts, seeds, fish, meat, dairy products and certain vegetables. It also appears in liver, cauliflower, salmon, carrots, bananas, soy flour, cereals and yeast. Most biotin in foods is bound to protein, although some dietary biotin is in the free form. Cooking and preserving reduce the biotin content of food.
A lack of biotin is rare. So the people reaching for it are rarely deficient. They are juggling deadlines, emails, workouts and, oh yes, life, and they want the visible stuff and the energy stuff handled in one move. Hoola is built for modern lives, busy schedules and high ambition, to help people feel bright, steady in mind, clear in thought and energised in action.
How should you take biotin day to day?
One 10 g scoop mixed into 300 to 400 ml of cold water, each morning. That is the ritual. One scoop, one glass, done before the inbox opens.
Take it in the morning or early afternoon, and keep it away from bedtime because of the 100 mg of caffeine. There is no half serve, no double serve and no weekly total. Hoola is one 10 g scoop a day.
Then let time do its part. Consistency over intensity, because most of our customers feel the biggest benefits with consistency. Adaptogens may take four to six weeks for their full benefits, and across weeks four to six people report sharper memory and mental agility, healthier skin and nails, and restorative sleep with deeper calm. The 150 g pouch is two weeks. Start there and see how you feel.
Frequently asked questions
What are the benefits of taking a biotin supplement?
Two main ones: energy metabolism and appearance. Biotin helps metabolise food, turning food into energy. As part of the B vitamin family, it contributes to hair and skin health and plays a role in supporting healthy hair, skin and nails.
In Hoola, biotin works inside an active B-complex that supports normal energy metabolism and the conversion of food into usable energy, supports the nervous system, supports healthy red blood cell formation through B6, B12 and folate, supports cognitive performance, and supports healthy skin, hair and nails through biotin, B2 and B3.
Is a biotin supplement worth taking if you already eat well?
It can be, and here is the balance. Biotin is an essential nutrient, naturally present in some foods and available as a dietary supplement. It is essential, which means you cannot live without it. A lack of biotin is rare.
The catch is that cooking and preserving reduce the biotin content of food. A measured daily amount takes the guesswork out of a diet that varies from Monday to Sunday.
Is biotin good for hair?
Yes, through keratin. Biotin is a water-soluble B vitamin involved in keratin production. That essential nutrient supports keratin production, a key protein for maintaining strength and structure. It is commonly taken for its perceived beauty benefits.
Is biotin good for skin and nails?
Yes. Biotin supports healthy nails and hair, and helps to maintain healthy skin. In Hoola it appears alongside B2 and B3 to support healthy skin, hair and nails, and to maintain and support skin health, integrity and structure. Zinc adds its own contribution, supporting immune function, skin health, taste and smell.
How much biotin do you need each day?
Most adults can safely take biotin supplements at doses ranging from 30 to 100 micrograms per day. There is no RDA or RNI for biotin, because a lack of it is rare. The daily amount needed is defined in several different ways. Hoola provides 3,000 mcg of biotin in each 10 g daily serve.
Why do some biotin products list 10,000 mcg?
Because a big number sells, and biotin is forgiving. It is a water-soluble vitamin, so any excess amounts are typically excreted in the urine rather than stored in the body, and the risk of toxicity from supplements is low.
We dose for what the body uses, then publish it. Biotin sits at 300 mcg per gram and 3,000 mcg per 10 g serve. Every per-serve figure is the per-gram figure times ten, and both are published. We provide full formula transparency, including dosages of all functional ingredients, nothing to hide.
What formats do biotin supplements come in?
Capsules, tablets and gummies are the usual three, varying in dosage and sometimes adding nutrients like zinc or selenium. Hoola is a powder.
A 10 g daily dose of actives does not fit a practical capsule count, so we made it a powder you mix and drink.
How do you take Hoola's biotin in Australia?
Mix one 10 g scoop into 300 to 400 ml of cold water, each morning. That serve delivers 3,000 mcg of biotin.
Hoola is a Listed Supplement on the Australian Register of Therapeutic Goods, AUST L 508472, with an ARTG start date of 8 August 2025 and Hoola Australia Pty Ltd as sponsor. It is manufactured in Australia by BJP Laboratories Pty Ltd in Yatala, QLD, with Australian laboratory testing.
Is Hoola suitable for vegans and vegetarians?
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.
Are biotin supplements different for women?
No. Hoola is one formula and one serve for everyone. There is no half serve, no double serve and no weekly total. Hoola is one 10 g scoop a day, built for modern lives, busy schedules and high ambition, to help people feel bright, steady in mind, clear in thought and energised in action.
Is biotin something you take every day, long term?
Yes. B vitamins, including biotin, are water-soluble. The body is never taking more than it needs, which is why a biotin supplement is usually considered safe to take daily.
