Second coffee, still foggy. The tabs are open, the brain is buffering, and the label on the back of your supplement says "cyanocobalamin" and you have no idea whether that matters. It does, a little, and it is easy to understand. Methylated B12 is mecobalamin (methylcobalamin), the active form of vitamin B12 that carries a methyl group instead of a cyanide group, and it is the form Hoola uses at 50 mcg per 10 g serve. Methylcobalamin is one of the active forms of vitamin B12, a water-soluble vitamin involved in red blood cell production, nervous system function and DNA synthesis. Cyanocobalamin has to be turned into an active form before your cells can use it. You want energy that feels bright, not frantic. Starting with the form your body already recognises is a sensible place to begin.
Key takeaways
- Methylated B12 is methylcobalamin, listed on our label as mecobalamin, and it is a naturally occurring, bioactive form of vitamin B12. Like folate, B12 comes in methylated and non-methylated forms.
- Cyanocobalamin is converted into methylcobalamin or adenosylcobalamin, the two active forms in humans. Methylcobalamin needs no conversion, so the body can use it directly for cellular processes, particularly in the nervous system.
- B12 sits behind red blood cell formation, nervous system function and everyday energy production.
- Hoola lists mecobalamin at 5 mcg/g, which is 50 mcg per 10 g serve, and the number is public under AUST L 508472.
- The form only works if the habit does. One 10 g scoop a day, same time each morning. Consistency over intensity.
What is methylated B12?
Methylated B12 is methylcobalamin, a form of vitamin B12 that has been activated through a process called methylation. Vitamin B12 is a general term for a group of related compounds called cobalamins. It is also known as cobalamin because it contains the mineral cobalt.
There is more than one cobalamin. The most common forms include cyanocobalamin, hydroxocobalamin and methylcobalamin. Research also lists adenosylcobalamin alongside those three. Like folate, vitamin B12 comes in methylated and non-methylated versions.
Methylcobalamin is the naturally occurring, bioactive one. It is one of the active forms of B12, the water-soluble vitamin your body leans on for red blood cell production, nervous system function and DNA synthesis. It is also the methylated version that some people find easier to absorb. On an ingredient panel, you will often see it written as mecobalamin. Same thing.
Why does vitamin B12 matter on a day that already feels full?
Because B12 sits underneath the three things a full day drains fastest: energy, blood, and nerves. Vitamin B12 plays a key role in methylation, energy production, red blood cell formation and neurological function.
Think about the chain. Red blood cells carry oxygen around your body. Vitamin B12 is essential for the healthy red blood cells that deliver that oxygen. B12 is also involved in DNA synthesis and regulation, fatty acid synthesis and energy production. Every cell depends on it for energy production, DNA expression and communication. It plays a key role in the normal functioning of the brain and nervous system and in the formation of blood. It helps make red blood cells, supports brain health and keeps your nervous system running properly.
That is the quiet infrastructure behind a morning that starts well and an afternoon that does not fall over. Hoola is built to maintain and support energy production, maintain and support nervous system function, aid healthy red blood cell production, relieve weariness, tiredness, fatigue and feelings of weakness, and reduce mental and cognitive fatigue. Energy without the edge. Steady, not stressed.
How does your body use mecobalamin compared with cyanocobalamin?
Your body uses mecobalamin as it is. Cyanocobalamin gets a processing step first. Vitamin B12 is not used directly in the human body, and it has to be translated into activating forms such as MeCbl or AdoCbl. When cyanocobalamin enters your body, it is converted into either methylcobalamin or adenosylcobalamin, the two active forms of B12 in humans. The body handles that conversion perfectly well. Methylcobalamin skips the queue, because it does not require conversion and can be used directly for cellular processes, particularly those involving the nervous system.
| Mecobalamin (methylcobalamin) | Cyanocobalamin | |
|---|---|---|
| Status in the body | Naturally occurring, bioactive form of B12 | Converted into methylcobalamin or adenosylcobalamin before use |
| Conversion needed | No, used directly by cells | Yes, B12 must be translated into MeCbl or AdoCbl |
| Activity | Active form | In mammalian cells, CNCbl and OHCbl are inactive forms, while AdoCbl acts as a coenzyme of methylmalonyl Co-A mutase in mitochondria |
| Nerve uptake | Compared with other analogs, MeCbl is the most effective at being taken up by subcellular organelles of neurons | Requires conversion first |
| In Hoola | Yes, 5 mcg/g, 50 mcg per 10 g serve | No |
Once it is active, B12 goes to work as a cofactor for two critically important enzymes. One of them is methionine synthase, needed to form methionine from homocysteine in the methylation cycle, which involves the methylation of DNA or proteins. Folate and vitamin B12 are the most important cofactors working with enzymes in that cycle. Methylation itself makes a vitamin easier for your body to absorb and use.
This is why our B group looks the way it does. Hoola uses 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. We use active and bioavailable forms wherever possible, in line with Australian quality manufacturing standards. Clarity that stays with you, without the overwhelm.

How do you get methylated B12 into your day?
Food first, then a daily supplement to cover the gap. Vitamin B12 is bound to protein in all animal products, including meat, dairy, fish, shellfish, eggs, poultry and organ meats. Methylcobalamin is a naturally occurring form that you can get through supplements as well as food sources such as fish, meat, eggs and milk. Methylcobalamin itself is not present in significant amounts in food, so what you eat mostly supplies vitamin B12 that your body converts into active forms. Plant foods bring plenty to the table, but they do not naturally contain vitamin B12. You will also find B12 in fortified foods such as cereals, protein bars and nutritional yeast.
Absorption asks something of you too. Digestion and absorption of vitamin B12 require good stomach acid and digestive enzyme levels. It also requires a transport protein made in the stomach, called intrinsic factor, that binds to vitamin B12 and allows absorption.
Supplements come from two main sources, cyanocobalamin or methylcobalamin. Cyanocobalamin is synthetic and is not found in nature. It appears in supplements more often because it is considered more stable and more cost effective than other forms of B12. We went the other way and used the active form.
Hoola is a daily wellness drink with nootropics, adaptogens, vitamins and minerals to support energy, focus and mental clarity. Mix one 10 g scoop into 300 to 400 ml of cold water each morning. There is no half serve, no double serve and no weekly total. Most of our customers feel the biggest benefits with consistency, so pick a time and keep it.

Scoop. Sip. Shine. Repeat.
Frequently asked questions
What are the benefits of methylated B12?
Methylated B12 supports red blood cell production, nerve function and DNA synthesis as a naturally active form of vitamin B12. It is involved in maintaining nervous system function, healthy red blood cell production and healthy immune system function. Vitamin B12 also supports energy production and relieves tiredness and fatigue. The practical upside is a day that holds its shape. Steadier energy, a mind that stays with you past lunch.
Which form of B12 is best absorbed?
Methylation makes a vitamin easier for your body to absorb and use, and methylcobalamin is the methylated version that some people find easier to absorb. Vitamin B12 supplements have a higher bioavailability than food. Among foods, dairy products tend to have a higher bioavailability than meat, meaning the B12 is better absorbed and raises blood levels of the nutrient.
How much B12 do adults need each day?
The recommended dietary allowance for vitamin B12 is 2.4 micrograms per day for adults. Hoola supplies mecobalamin at 5 mcg/g, which is 50 mcg per 10 g serve, and that figure is listed on the ARTG under AUST L 508472 alongside every other active.
What are methylated vitamins?
Methylated vitamins are forms of certain vitamins that have been activated through a process called methylation. Like folate, vitamin B12 comes in methylated and non-methylated forms. You can find them in vitamin B12 supplements or in compounded products such as methylated multivitamins or a vitamin B complex.
How does folate relate to methylated B12?
They work the same cycle, one after the other. The methylation cycle begins with folate. Folate is converted into its active form, 5-methyltetrahydrofolate, through the folate cycle, and MTHFR is directly responsible for creating that active form. Vitamin B12 is the cofactor needed by the enzyme that converts homocysteine to methionine, which is why low B12 levels can also raise homocysteine. Hoola pairs levomefolate glucosamine at 890 mcg per 10 g serve with mecobalamin at 50 mcg per 10 g serve for that reason.
What are B vitamins good for?
B vitamins support normal energy metabolism and the conversion of food into usable energy, support the nervous system, support healthy red blood cell formation (B6, B12, folate), support cognitive performance, and support healthy skin, hair and nails (biotin, B2, B3). Vitamin B12 specifically helps make red blood cells, supports brain health and keeps your nervous system functioning properly. The second enzyme that requires B12 as a cofactor is l-methylmalonyl-CoA mutase. That enzyme produces succinyl CoA, which is involved in energy metabolism and short chain fatty acid production.
Should you choose a methylated B12?
Yes, if you want the form your cells can use without a conversion step. Research directly comparing the two forms is limited. What we do know is that methylcobalamin is the methylated version some people find easier to absorb, and that it needs no conversion before your body puts it to work. A healthy vitamin B12 level sits between 500 and 800 µmol. We chose mecobalamin for Hoola and published the dose so you never have to guess.
What is the difference between methylcobalamin and cyanocobalamin?
Both cyanocobalamin and methylcobalamin are forms of vitamin B12. The chemical difference is small and the practical difference follows from it: in MeCbl, the cyanide is replaced by a methyl group. When cyanocobalamin enters your body, it is converted into either methylcobalamin or adenosylcobalamin, the two active forms of vitamin B12 in humans. Methylcobalamin arrives already active.
