Pure Vitamins UK Lion's Mane mushroom extract with Vitamin B1 for making Lion's Mane Coffee

Lion's Mane Coffee: What It Is and How to Make It

by Dr. Miron in News

Lion's mane coffee is the simple morning ritual of stirring lion's mane mushroom into your brew, a habit that has grown out of the mushroom's long history in East Asian tradition. This guide explains exactly what it is, whether it contains caffeine, what it tastes like and how to make it at home, kept honest about what the mushroom can and cannot do.

Pure Vitamins UK Lion's Mane 4000mg extract with Vitamin B1 for adding to coffee

What is lion's mane coffee?

Lion's mane coffee is simply ordinary coffee with lion's mane mushroom (Hericium erinaceus) added, usually as an extract powder stirred in, or by taking a lion's mane supplement alongside your morning cup. Some people buy pre-blended mushroom coffee; others keep their favourite coffee and add lion's mane separately for more control over both. Think of it as a pleasant daily ritual built around a mushroom people have valued for centuries, rather than a magic cup.

TL;DR

  • What it is: coffee with lion's mane extract stirred in, or a capsule taken with your cup.
  • Caffeine: comes only from the coffee; lion's mane has none of its own.
  • Taste: mild and earthy; a good extract mostly disappears into the cup.
  • How: brew as normal, whisk in a measured dose of extract, add milk to taste.
  • Honest note: the human research on focus is early and mixed; our formula also adds vitamin B1, which supports normal nervous-system function.

Why people add lion's mane to coffee

The appeal is mostly ritual: folding a mushroom people associate with mental performance into a drink they already have every morning. Lion's mane contains compounds that have drawn scientific interest, including hericenones, erinacines, beta-glucans and ergothioneine, though a 2026 review retrieved from the literature stresses that these functional properties are predominantly supported by in vitro and animal studies rather than settled human outcomes (Raja-Razali et al., 2026, DOI). The human research on focus in healthy adults is early and mixed: one small placebo-controlled study found faster performance on a single timed task after a dose (Docherty, Doughty and Smith, 2023, DOI), while an acute crossover found no significant overall effect on cognition or mood (Surendran et al., 2025, DOI). So enjoy lion's mane coffee as a pleasant habit, not a guaranteed cognitive lift. We unpack the category in what is a nootropic.

Does lion's mane coffee contain caffeine?

The caffeine comes entirely from the coffee, not the mushroom: lion's mane itself contains no caffeine. So a lion's mane coffee has exactly as much caffeine as the coffee you brewed; the mushroom neither adds nor removes any. If you use a pre-blended mushroom coffee, check the label, as some blends use less actual coffee per serving. And if you want lion's mane without the caffeine, simply take it in the evening or as a capsule instead. For more on this, see when to take lion's mane.

What does it taste like?

Done well, you barely notice it. Lion's mane has a mild, slightly earthy and subtly nutty character that blends into coffee's stronger flavour without dominating, and a small amount of good-quality extract typically disappears into a normal-tasting cup. If a mushroom coffee tastes strongly fungal or bitter, that usually points to a lower-quality or over-dosed blend rather than how it should be.

How to make lion's mane coffee at home

  • Brew your coffee as normal. Any method works, from cafetiere to espresso to filter.
  • Add lion's mane extract. Stir a measured amount of extract powder into the hot coffee, following the product's serving guidance.
  • Blend or whisk. A quick whisk or milk frother helps it dissolve smoothly and avoids clumps.
  • Add milk and sweetener to taste, exactly as you normally would.

If you would rather not measure powder into a drink, the simplest route is to take a lion's mane supplement such as our Lion's Mane 4000mg with your coffee, same routine, no stirring. For how much to use, see our lion's mane dosage guide.

Does the heat of coffee destroy the compounds?

This is a fair question. Lion's mane beta-glucans are relatively robust to the brief heat of stirring into a hot drink, and most supplement extracts have already been processed with hot water or alcohol, so a quick stir into coffee is not a meaningful problem. It is not the same as prolonged boiling. If you are using a concentrated extract, the dose on the label already accounts for normal use, so you are not losing the bulk of it by adding it to coffee.

Pre-blended mushroom coffee vs adding your own extract

Pre-blended mushroom coffees are convenient but vary a lot: some contain only a token amount of mushroom, and the coffee quality can be an afterthought. Adding your own extract to coffee you already like gives you control over both the dose and the brew, and lets you see exactly what extract and ratio you are getting. The trade-offs between extract types and ratios are covered in full-spectrum vs extract and what's in lion's mane.

When to drink it, and a note on caffeine

Most people have lion's mane coffee in the morning, which suits the caffeine. Because the caffeine is from the coffee, the usual sensible limits apply: caffeine late in the day can disrupt sleep, and UK guidance suggests pregnant women keep total caffeine to around 200 mg a day. If caffeine does not suit you, taking lion's mane as a capsule with a decaf or in the evening gives the same routine without the stimulant.

A few cautions worth knowing

Lion's mane is a culinary mushroom and is generally well tolerated, with mild digestive upset the most commonly reported effect; allergy is possible. The main thing to watch with lion's mane coffee is the coffee itself: keep caffeine sensible, especially in pregnancy. If you are pregnant, breastfeeding, taking medication or managing a health condition, speak to your GP or pharmacist before starting a new supplement.

Where vitamin B1 fits in our formula

Our Lion's Mane 4000mg pairs the mushroom with vitamin B1 (thiamine), which supports the normal function of the nervous system and normal psychological function, so it is a sensible companion for a morning routine while the mushroom is presented honestly on its heritage and composition. It is formulated in the UK and tested for purity and heavy metals at our GMP-certified facility.

Frequently asked questions

Does lion's mane coffee have caffeine?

Only from the coffee. Lion's mane contains no caffeine of its own, so the drink has exactly as much caffeine as the coffee you brewed. Pre-blended mushroom coffees vary, so check the label.

What does lion's mane coffee taste like?

Mild and slightly earthy. A good-quality extract mostly disappears into coffee's flavour. A strong fungal or bitter taste usually signals a low-quality or over-dosed blend.

Does heating lion's mane in coffee ruin it?

No. Its beta-glucans tolerate the brief heat of a hot drink well, and most extracts are already processed with heat or alcohol, so stirring into coffee is fine. It is not the same as prolonged boiling.

When should I drink lion's mane coffee?

Most people have it in the morning to suit the caffeine. If caffeine does not agree with you, take lion's mane as a capsule or with decaf instead, and keep caffeine modest in pregnancy.

High-strength biotin 10,000 mcg tablets for hair and skin by Pure Vitamins UK

Which is better, B12 or biotin?

Reviewed and updated: 28 July 2026 If you are asking which is better, B12 or biotin, the honest answer is that neither one wins, because they are not really competing for the same job. Vitamin B12 and biotin are both B vitamins, but they look after different parts of your body, so the right question is not which is stronger, it is which one fits what you are trying to support, and whether you might actually benefit from both. B12 or biotin: the short version I am Dr. Miron, Founder of Pure Vitamins UK, and this is the comparison I get asked about more than almost any other. People see biotin marketed for hair and B12 marketed for energy, assume they overlap, and try to pick a winner. They do not overlap much at all. Biotin is best known for its role in maintaining normal hair and skin, while B12 is the one your body leans on for normal red blood cell formation, a normal nervous system, and reducing tiredness and fatigue. Choose based on your goal, not on which sounds more powerful. The quick answer, at a glance What they are: both are water-soluble B vitamins your body cannot store in large amounts, so a steady daily intake matters. Reach for biotin if: your focus is hair and skin, or you want support for normal energy-yielding metabolism and macronutrient metabolism. Reach for B12 if: your focus is everyday energy, the nervous system and red blood cells, especially if you eat little or no animal food. Can you take both? Yes. They are complementary B vitamins with no reason to compete, and many people sensibly take both. The one catch: very high-strength biotin can interfere with some blood tests, so mention it to whoever takes your bloods. What biotin actually does Biotin, sometimes called vitamin B7, is a coenzyme your body uses to help turn the food you eat into usable energy. In the language of the GB nutrition and health claims register, biotin contributes to normal macronutrient metabolism, normal energy-yielding metabolism, the normal functioning of the nervous system, normal psychological function, and the maintenance of normal hair and normal skin. That hair and skin role is exactly why biotin ended up on every beauty shelf. Here is the part the marketing tends to skip. The research on biotin for hair is genuinely useful, but it is honest about its limits. A systematic review of biotin for hair loss found that improvement was seen in people who had an underlying biotin deficiency or a specific condition, and concluded there is a lack of good evidence that supplementing helps people who are not deficient (Patel, Swink and Castelo-Soccio, 2017, https://doi.org/10.1159/000462981). A broader review of vitamins and minerals in hair loss reached a similar view, that micronutrients matter most when a deficiency is present (Almohanna and colleagues, 2019, https://doi.org/10.1007/s13555-018-0278-6). So biotin is a sensible daily nutrient for hair and skin maintenance, not a guaranteed hair-growth switch. One small point of accuracy worth knowing: the authorised claim in the UK links biotin to normal hair and skin, while it is actually zinc that carries the authorised claim for the maintenance of normal nails, which is why our hair, skin and nails thinking usually pairs the two. You can read more on that in our guide to what actually supports normal nails. What vitamin B12 actually does Vitamin B12, or cobalamin, does heavier lifting across the body. It contributes to normal energy-yielding metabolism, the normal functioning of the nervous system, normal red blood cell formation, normal homocysteine metabolism, normal psychological function, and the reduction of tiredness and fatigue. In plain terms, it is central to making healthy red blood cells, keeping nerves working properly, and supporting steady everyday energy. B12 also has a well-documented deficiency story, which is really a story about biology rather than any product. B12 has an important role in DNA synthesis, methylation and cellular metabolism, and deficiency can produce both blood and neurological effects if it is missed for a long time (Green and colleagues, 2017, https://doi.org/10.1038/nrdp.2017.40). Because the body mostly gets B12 from animal foods, people following vegan or vegetarian diets, older adults, and anyone with absorption problems are more likely to run low, and clinical guidance stresses paying attention to symptoms alongside blood markers (Obeid and colleagues, 2024, https://doi.org/10.3390/jcm13082176). If you eat little or no animal food, this is the one I would look at first, and our full vitamin B12 UK guide goes deeper on who is most at risk. So which is better, B12 or biotin? The most useful way to answer which is better, B12 or biotin, is to stop ranking them and match each to a goal. If your interest is hair and skin, biotin is the more relevant nutrient. If your interest is energy that comes from healthy blood and nerves, or you are worried about a dietary gap, B12 is the more relevant one. Neither is a stronger version of the other, and picking the wrong one for your goal is the only real mistake here. A few honest scenarios help: You want to support your hair and skin routine: biotin is the natural fit, ideally alongside a varied diet. See our honest take on biotin versus collagen for beauty if you are weighing those two as well. You feel persistently tired and eat little animal food: B12 is the more logical starting point, and worth a conversation with your GP. You are covering general nutrition: both appear together in most B-complex and multivitamin formulas for good reason, and you can read how we think about that in our best vitamins for hair, skin and nails guide and the wider supplement guides hub. Can you take B12 and biotin together? Yes, and there is no clash. They are both B vitamins, they act on different pathways, and neither blocks the other. Plenty of people take a dedicated biotin for hair and skin and a separate B12 for energy and dietary cover, or simply take a B-complex that includes both. If you prefer to keep things targeted, you can pair our high-strength biotin tablets with a vitamin B12 supplement and take them at whatever time suits your routine, since consistency matters far more than timing. How much of each do you need? For labelling in the UK, the nutrient reference value, or NRV, is 50 micrograms for biotin and 2.5 micrograms for B12. Those NRVs are the baseline a normal diet aims to cover, not a ceiling. Everyday adequate intakes are modest: EFSA sets an adequate intake for biotin around 40 micrograms a day, and the UK reference nutrient intake for B12 is roughly 1.5 micrograms a day for adults. Supplements often sit well above those figures, which is normal for water-soluble B vitamins. A 10,000 microgram biotin tablet, for example, provides a very high multiple of the NRV, and a B12 supplement is frequently dosed high to account for the fact that only a fraction is absorbed at once. Neither biotin nor B12 has a formal tolerable upper intake level set, largely because they are water-soluble and surplus amounts are mostly excreted rather than stored. That does not mean more is automatically better, and for biotin in particular there is a specific reason to be thoughtful about very high doses, which I will come to next. If you want the detail on strengths, our guide to how much biotin you actually need lays it out. The one thing to know before a blood test This is the part most hair-and-energy articles leave out, and it genuinely matters. High-strength biotin can interfere with some laboratory blood tests. Many common tests use biotin-based technology, and when there is a lot of biotin in your bloodstream it can push certain results falsely high or falsely low. A review of this problem lists thyroid tests, troponin (a heart marker), and hormone and vitamin tests among those that can be affected, and notes the interference tends to appear at higher intakes (Moerman and Delanghe, 2020, https://doi.org/10.1080/17843286.2020.1780770). The practical takeaway is simple and reassuring. If you take a high-strength biotin, tell whoever is arranging your blood tests, and it is commonly suggested to pause biotin for a couple of days beforehand so your results are read accurately. This is also a neat reason the two vitamins connect: biotin can distort some of the very markers used around B12 and thyroid testing, so honesty with your clinician keeps the picture clean. Signs your levels might be low Frank biotin deficiency is uncommon in people eating a normal varied diet, because biotin is widespread in food and also made by gut bacteria. When it does occur it can show up as thinning hair, skin changes and brittleness. B12 shortfall is more common, especially with a plant-based diet or with age, and can show as unusual tiredness, a pale or washed-out look, pins and needles, or low mood. None of this is something to self-assess from a blog, so if symptoms are persistent, a GP and a blood test are the sensible route. Where to get them from food Food first is always my starting point. Biotin is found in eggs (especially the yolk), nuts, seeds, oily fish, sweet potatoes and wholegrains. B12 is almost entirely found in animal foods such as meat, fish, eggs and dairy, plus fortified foods like some plant milks and breakfast cereals. That single difference explains a lot: it is much easier to fall short on B12 on a vegan diet than on biotin, which is one of the clearest cases where a supplement earns its place. How to choose and take them well When you are comparing products, look past the front of the label. For B12, the form matters to some people, which is why we use methylcobalamin and adenosylcobalamin, the body-ready forms, in our B12; you can read the differences in our explainer on B12 forms. For biotin, the useful details are the actual microgram strength and the NRV percentage, so you know exactly what you are getting. Both of ours are formulated in the UK and tested for purity and heavy metals at our GMP-certified facility, which is the standard I would want as a buyer. On timing, do not overthink it. Both are water-soluble, so take them with a little food if that helps you remember, keep it daily, and let consistency do the work. If you like a tidy routine, the whole point of our Pure Vitamins range is that you can build exactly the stack your goals call for. What to realistically expect Set expectations kindly. If you are genuinely low in a nutrient, correcting that gap can make a real difference over weeks to months. If your levels are already fine, topping up further is unlikely to transform anything, and that is true for both biotin and B12. Supplements support a good diet and lifestyle, they do not replace them, and the most honest promise any brand can make is a clean, well-labelled product that helps you cover your bases. A few cautions worth knowing If you are pregnant, breastfeeding, or managing a health condition, check with a healthcare professional before starting a new high-strength supplement. Tell whoever arranges your blood tests that you take biotin, as high-strength biotin can affect some results. Persistent tiredness, tingling or hair changes deserve a proper look from your GP rather than guesswork. Stick to the stated dose on the label unless a professional advises otherwise. Frequently asked questions Is B12 or biotin better for energy? For energy specifically, B12 is the more relevant of the two, because it contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue, and it is central to red blood cell formation. Biotin also contributes to normal energy-yielding metabolism, but it is better known for hair and skin. Is B12 or biotin better for hair? Biotin is the one associated with the maintenance of normal hair. That said, the research shows the clearest benefit in people who are actually low in biotin, so it supports a hair routine rather than guaranteeing regrowth. Can I take B12 and biotin at the same time? Yes. They are complementary B vitamins with no interaction to worry about, and many people take both, either as separate supplements or within a B-complex or multivitamin. Does biotin really affect blood tests? High-strength biotin can interfere with some laboratory immunoassays and shift certain results, so it is best to tell your clinician you take it and, where advised, pause it for a day or two before testing. Which should I choose if I am vegan? B12 is usually the priority for anyone on a vegan or largely plant-based diet, because it is found almost entirely in animal foods. Biotin is more widely available from plant foods, so shortfalls are less common.
