Key takeaways
- B12, also called cobalamin, is a vitamin the body uses to make and support healthy nerve cells. It is essential for energy production and for your nervous system.
- Hoola's 10 g daily serve carries 50 mcg of mecobalamin, or 5 mcg per gram. Both figures are published.
- Mecobalamin is one of the coenzyme forms active in humans, so it needs no extra conversion step.
- Low B12 is most common in older adults and in people eating little or no animal food.
- One 10 g scoop in cold water each morning. The benefit sits in consistency, not intensity.
What is vitamin B12, and what does it do in the body?
Vitamin B12, also called cobalamin, is an important vitamin your body uses to make and support healthy nerve cells. It also makes healthy red blood cells and the genetic material inside cells called DNA.
Think of it as the maintenance crew for your wiring. B12 helps maintain the health of the conductive coating that surrounds and protects nerves. It is required for the synthesis of fatty acids in myelin, and, with folate, for DNA synthesis. That is a lot of quiet work happening while you answer emails.
The blood side matters just as much. B12 is a water-soluble vitamin required for a healthy nervous system, a healthy immune system and healthy red blood cell production. Adequate intake is essential for normal blood function and normal neurological function. In Hoola, B12 sits with B6 and folate to support healthy red blood cell formation and to aid healthy red blood cell production.
Where does vitamin B12 fit in a day that already feels loud?
It fits at the base. B12 is not a stimulant. It is one of the nutrients your body uses to turn food into energy it can actually spend, which is why it belongs in a routine built for steadiness rather than a spike.
Most people do not arrive here because of a blood test. They arrive because the mind feels full but not focused, and energy feels inconsistent from one afternoon to the next. B12 is a commonly deficient vitamin in adults, so it is a reasonable place to start looking.
We built Hoola for energy without the edge. The formula supports energy production and stamina in a way that feels steady, not stressed, and it helps relieve tiredness, fatigue and feelings of weakness, including mental fatigue. A bright life starts with a steady mind. Energy without the jitter or the crash is the whole brief.
Which form of vitamin B12 is in Hoola, and how much do you get?
Mecobalamin, at 5 mcg per gram and 50 mcg per 10 g serve. In milligrams, that is 0.05 mg. For context, the recommended daily amount of vitamin B-12 for adults is 2.4 micrograms. The Recommended Dietary Allowance for vitamin B12 varies by age.
Every per-serve figure below is the per-gram figure times ten, and both are published. Vitamins are your daily essentials, so we dose them for smart daily support rather than mega doses.
A few of those micrograms convert neatly if you prefer milligrams. 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.
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. A 10 g daily dose of actives does not fit a practical capsule count, which is why Hoola is a powder.
Why did Hoola choose mecobalamin instead of another B12 form?
Because it is already one of the coenzyme forms your body uses. Vitamin B12 can be converted to either of the two cobalamin coenzymes active in humans: methylcobalamin and 5-deoxyadenosylcobalamin. Mecobalamin is that first one, so it does not need an additional conversion step before it can work.
B12 is a family, not a single molecule. It is the generic descriptor for corrinoid compounds showing the biological activity of cyanocobalamin. The main cobalamins with physiological action are hydroxycobalamin, methylcobalamin and deoxyadenosylcobalamin. Different labels pick different members of that family, and they are not identical on the shelf.
We apply the same rule across the B group. 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. Hoola uses active and bioavailable forms wherever possible, in line with Australian quality manufacturing standards. Minerals and vitamins should work with you, not pass straight through you.
How does vitamin B12 work with the rest of the 27-ingredient formula?
It works as one player in a squad, not 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.
B12 has direct partners inside that formula. It is required, in conjunction with folate, for DNA synthesis, and Hoola carries 890 mcg of levomefolate glucosamine alongside 15.7 mg of pyridoxal 5-phosphate. Together, B6, B12 and folate support healthy red blood cell formation. The wider active B-complex supports normal energy metabolism and the conversion of food into usable energy, supports the nervous system, supports cognitive performance, and supports healthy skin, hair and nails through biotin, B2 and B3.
Then the herbs pick up the rest of the day. Cordyceps and Korean ginseng support natural energy production and help reduce occasional tiredness. Bacopa supports memory, recall and retention. enXtra supports mental alertness, attention and sustained focus. KSM-66 Ashwagandha helps support the body's natural stress response, and Reishi supports healthy sleep patterns and relaxation without sedation. Clarity that stays with you, without the overwhelm.
Hoola is a streamlined 27-ingredient formula for everyday performance, while IM8 takes an extensive 90-ingredient whole-body approach.
Who tends to go looking for a vitamin B12 supplement?
Two groups, mostly: older adults, and people eating little or no animal food. B12 deficiencies are fairly common, particularly among older adults, people who follow a vegan diet, and those who take certain medications.
Age changes the maths. The ability to absorb vitamin B-12 lowers as a person gets older. An estimated 3.2% of adults ages 50 or older have very low B12 levels, and up to 20% may have borderline deficiency.
Diet changes it too. Humans obtain almost all of their vitamin B12 from animal foods, although some plant-based sources exist, such as certain algae and plants exposed to bacterial action or contaminated by soil or insects. People who follow a vegetarian or vegan diet can sometimes have low levels. Hoola is vegan, sugar free, gluten free, naturally flavoured and made without artificial fillers, so it fits that pattern of eating without a workaround.
The third group is everyone else. The people stacking "what was I doing again?" moments by Wednesday, who want their best energy showing up every morning rather than being saved for weekends and holidays.
How should you take vitamin B12 day to day?
Daily, by mouth, at the same time. Some people take B12 as a vitamin by mouth. Your body has a buffer as well, since B12 can be stored in the liver for many years. That is exactly why a steady daily habit beats an occasional big hit.
The Hoola ritual is one 10 g scoop mixed into 300 to 400 ml of cold water, each morning. Take it in the morning or early afternoon, and avoid it close to bedtime because of the caffeine. There is no half serve, no double serve and no weekly total. Hoola is one 10 g scoop a day.
Most of our customers feel the biggest benefits with consistency. We made Hoola to keep wellness simpler, smarter and more enjoyable for anyone who wants to fuel themselves and get more out of life. One scoop, one glass of cold water, one less decision before 8am.
Frequently asked questions
What can you expect in the first few weeks of a daily B12?
Expect a gradual lift rather than a switch flipping. In week one, most people notice smooth energy without the crash, sharper focus in the mornings, a subtle lift in mood and mental clarity, and a feeling of being more balanced under pressure.
The full arc takes longer. Adaptogens may take four to six weeks for their full benefits, so the honest frame is a trial run. The 150 g pouch is two weeks. Take it daily and see how you feel.
Can you buy vitamin B12 tablets at the supermarket?
Yes. B12 supplements are available at every drugstore and supermarket. Availability is not the hard part. Checking which form you are getting and whether the dose is published on the label is the part most people skip.
What names does vitamin B12 go by on a label?
Vitamin B12 is also called cobalamin. On an ingredient panel you may also see the specific form named instead of the vitamin: mecobalamin is the active B12 form we use, in the same way pyridoxal 5-phosphate stands in for B6, levomefolate for folate and riboflavin sodium phosphate for B2. Those forms are ready for the body to use without additional conversion steps.
Which foods are the richest sources of vitamin B12?
Animal foods lead the list. Food sources include poultry, meat, fish and dairy products. Rich sources include beef, liver, clams, poultry, fish, fortified cereals, eggs, cheese, yogurt, milk, and fortified plant milks such as soy, almond or rice milks. Food companies also may add vitamin B-12 to breakfast cereals.
How do you choose a vitamin B12 supplement?
Start with the form, then the number. Look for an active form rather than one that needs converting, and look for a label that publishes the dose instead of hiding it inside a blend.
We use active and bioavailable forms wherever possible, in line with Australian quality manufacturing standards. We provide full formula transparency, including dosages of all functional ingredients, with nothing to hide. 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.
What can Australian buyers check before they commit?
Check the register entry. 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 the sponsor.
You can also check where it is made. Hoola is manufactured in Australia by BJP Laboratories Pty Ltd in Yatala, Queensland, with Australian laboratory testing.
Where can vegetarians and vegans get vitamin B12?
From fortified foods and supplements, since the vitamin is abundant in animal-based foods including beef, salmon and dairy products. Some other foods may be fortified with it. A daily supplement covers the gap without rebuilding your plate, which is why our 50 mcg of mecobalamin sits inside a vegan formula.
Do fruit and vegetables contain vitamin B12?
No. Plant foods don't have vitamin B-12. The supply sits on the animal side of the plate instead, and about 25% of vitamin B12 comes from red meats.
Is Hoola's vitamin B12 suitable for vegans?
Yes. Hoola is vegan, sugar free, gluten free, naturally flavoured and made without artificial fillers. We hold that line across the harder ingredients too, using Vitashine vegan vitamin D3 and Lyc-O-Beta plant-source beta-carotene.
Do you still need a separate B12 tablet if you take Hoola?
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. Your 10 g scoop already carries 50 mcg of mecobalamin, with B6 and folate beside it.
Hoola is a daily wellness drink with nootropics, adaptogens, vitamins and minerals to support energy, focus and mental clarity. One scoop covers the B12, and the other 26 actives at the same time.
How much vitamin B12 do adults need each day?
2.4 micrograms. That is the recommended daily amount of vitamin B-12 for adults. Older adults may need to eat 10 to 12 mcg of vitamin B-12 to get enough of this vitamin.
Is a B-complex a better choice than B12 on its own?
A complex covers more ground, because the B vitamins share the work. Together, the active B-complex 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.
Here is what a full complex looks like at Hoola doses, per gram and per 10 g serve.
