Ginkgo Biloba 50:1: Flavonoids, Terpene Lactones and Blood Flow

by Dr. Miron in News

Reviewed and updated: 23 July 2026

Ginkgo biloba is the ingredient in Man's Prime Blue with the longest CV, and the one whose whole reputation is built on one thing: circulation. In this piece I will walk you through it properly, the tree it comes from, the two families of compounds that do the work, how those compounds are absorbed, and the blood-flow mechanisms, including the nitric oxide side, that explain why ginkgo has been a circulation herb for centuries. As always, no promises, just the chemistry and the heritage, so the reasoning behind the formula is transparent.

A living fossil

Ginkgo is one of the oldest tree species still on earth, effectively unchanged for something like two hundred million years, which is why it is often called a living fossil. Its fan-shaped leaves have been used in traditional Chinese herbalism for centuries, and in modern Europe a standardised leaf extract became one of the most studied and most widely used plant preparations there is. Its traditional and best-evidenced association is with blood flow and circulation, and because so much of male vitality, sexual wellbeing very much included, runs on healthy blood flow, that circulation heritage is exactly why men have taken an interest in ginkgo and why it belongs in a men's botanical complex.

The two families of compounds

Ginkgo's activity comes from two distinct groups of molecules working together. First, the flavonol glycosides, roughly 24% of a proper standardised extract, built mostly on quercetin, kaempferol and isorhamnetin. These are the antioxidant, free-radical-scavenging side of ginkgo. Second, and unique to this plant, the terpene lactones, around 6%, which split into the ginkgolides (A, B and C, about 3.1% of the extract) and bilobalide (about 2.9%). According to PubMed, a food-science review of ginkgo describes exactly this composition of the standardised extract, 24% flavonoid glycosides and 6% terpene lactones with under 5 parts per million of the allergenic ginkgolic acid, and notes that the flavonoid and terpenoid constituents appear to act in a complementary way (Mahadevan and Park, 2007, DOI).

This is what "50:1, standardised, 85 to 100% purity" on our label is really about. A 50:1 concentrate means fifty parts of leaf reduced to one part of extract, standardised so the flavonoid and terpene-lactone percentages are consistent, and purified so the ginkgolic acid is kept right down. A regulatory safety assessment of ginkgo extract from EFSA describes the same benchmark composition, at least 24% total flavonoids and at least 6% terpene lactones with ginkgolic acids held to trace levels (EFSA, 2024, DOI).

How ginkgo is absorbed

The two compound families behave differently once you swallow them, which is part of ginkgo's charm. The terpene lactones, the ginkgolides and bilobalide, are relatively well absorbed and appear in the bloodstream with fairly short, predictable half-lives of a couple of hours (EFSA, 2024, DOI). The flavonoid glycosides are the opposite story: in their sugar-bound glycoside form they are poorly absorbed, and your gut bacteria have to cleave them into their aglycone forms before much gets through, after which the liver conjugates them further (Mahadevan and Park, 2007, DOI). That gut-conversion step is a recurring theme with botanicals, and it is another reason a clean, well-standardised extract taken consistently makes more sense than a random dose of powdered leaf.

The blood-flow mechanisms

Ginkgo works on circulation through more than one route, which is what makes it interesting rather than a one-trick herb. The headline mechanism is platelet-activating factor, or PAF: the ginkgolides, especially ginkgolide B, are natural PAF antagonists, meaning they dial down the signal that makes platelets clump together, which supports smoother blood flow (Noor-E-Tabassum et al., 2022, DOI). On top of that, the food-science review describes ginkgo stimulating endothelium-derived relaxing factor, which is nitric oxide, the same vessel-widening signal we talked about with ginseng, alongside its antioxidant and microcirculatory actions, with the flavonoids and terpenoids complementing each other (Mahadevan and Park, 2007, DOI). So you have an antioxidant fraction protecting the vessel lining, a terpene fraction easing platelet stickiness, and a nudge to the nitric oxide pathway that relaxes the vessels themselves.

Why that matters for male vitality

Healthy circulation quietly underpins a great deal of how a man feels day to day, from clear-headedness to physical vitality to sexual wellbeing, all of which lean on good blood flow and nitric-oxide signalling. Ginkgo has been the circulation herb for centuries, and in modern use that reputation has extended quite naturally to the blood-flow side of male sexual wellbeing, which is precisely why it sits in the Blue formula. I will still leave the conclusion to you, my job here is to show you the mechanism honestly rather than make a promise, but you can see where it points.

Why it sits in Man's Prime Blue, at 50:1

Blue is our fast-absorbing formula, and ginkgo is its circulation anchor. Using a high-grade 50:1 standardised leaf extract means the flavonoid and terpene-lactone content is concentrated and consistent, and the low ginkgolic-acid purity spec is a genuine quality and tolerability marker, not just a number. Alongside ginseng and maca it rounds out a complex aimed at circulation and everyday vitality, in a plant-based capsule designed to be taken as and when it suits you rather than as a daily foundation, which is the job Gold does.

A few cautions worth knowing

Ginkgo is the ingredient here that needs the most respect, precisely because it works on platelets and blood flow. Please check with your GP or pharmacist first if any of these apply:

  • Blood thinners and antiplatelet medicines: this is the big one. Because ginkgolides reduce platelet aggregation, ginkgo can add to the effect of warfarin, aspirin or similar, so do not combine them without medical advice.
  • Surgery or dental procedures: stop ginkgo at least two weeks beforehand and tell your surgical team, again because of the effect on platelets.
  • A seizure history: caution is generally advised with ginkgo, so speak to your doctor first.
  • Other regular medication: ginkgo can interact with several medicines, so if you take anything regularly, check before adding it.
  • Pregnancy and breastfeeding: not suitable. This is a men's formula, but worth stating.

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.
