Walk down the brain-supplement aisle and you will meet two completely different products wearing the same label. One is a pharmacy multivitamin with a botanical added. The other is a twenty-ingredient blend with a name like a spacecraft. Both get called nootropics. The word tells you nothing about either.
I sell one of these products, so weigh what follows accordingly. What I can offer in return is the thing this category is worst at: a straight account of what is actually in these formulas, what any of it is permitted to claim, and which numbers on a label are worth comparing.
First, "nootropic" is a marketing word
It has no standing in GB food law. There is no legal definition, no threshold a product has to meet and no test it has to pass. A brand can print it on a pot containing a pinch of green tea extract, and nothing about that is irregular.
What does have standing is the GB nutrition and health claims register. Since January 2021 it is the only source of wording a UK supplement may use to say what an ingredient does. And it is short. For this category, the entire permitted vocabulary comes down to a handful of vitamins and minerals:
- Normal cognitive function — zinc, iodine and iron
- Normal mental performance — pantothenic acid (vitamin B5)
- Normal psychological function — niacin, vitamin B6, vitamin B12, folate, biotin, magnesium, vitamin C and thiamin
- Normal functioning of the nervous system — niacin, vitamin B12, iodine, vitamin B6, biotin, copper, magnesium and others
- Reduction of tiredness and fatigue — vitamin B12, folate, niacin, pantothenic acid, riboflavin, vitamin B6, vitamin C, magnesium and iron
A nutrient only carries its claim if the product provides at least 15% of the Nutrient Reference Value per serving. Below that it can be listed, but it cannot say anything.
None of the famous ingredients can claim a thing
Bacopa monnieri. Ginkgo biloba. Korean panax ginseng. Lion's mane. Citicoline. Rhodiola. L-theanine. These are the ingredients the category is built on and sold on, and not one of them has an authorised health claim in Great Britain.
The position is slightly more interesting than a flat no. Around two thousand botanical claims were still being assessed when the register was carried over after EU exit, and they were parked as "on hold" — never approved, never formally rejected. Some brands still use them on that basis. We don't, because "on hold" is not "authorised", and botanical claims are consistently near the top of the list of things UK enforcement picks up on.
The practical effect for you as a buyer: a label can tell you a capsule contains 300mg of ginkgo. It should not be telling you what that 300mg is going to do for you.
The caffeine question, which almost everyone gets wrong
You will see it stated confidently that caffeine is "EFSA-approved for alertness and concentration". It isn't. EFSA issued positive scientific opinions, and then the European Parliament vetoed the regulation that would have authorised the claims. They were never adopted, and that position carried into GB law.
So caffeine may be declared, and it may be described — but no supplement sold in the UK may tell you its caffeine will sharpen your focus. That applies to everyone, including us: our own formula contains 100mg of caffeine per serving and we cannot make a claim for a milligram of it. I mention it because a brand that gets this wrong on its own website has told you something about how carefully the rest of the label was put together.
The four kinds of brain supplement on sale in the UK
The pharmacy multivitamin with a botanical in it
Best for: someone who wants the claim-carrying nutrients in a familiar package from a name they recognise.
This is the mainstream of the UK market and it is more sensible than the internet gives it credit for. Vitabiotics Neuromind Original — renamed from Neurozan, so any guide still calling it Neurozan is out of date — is a broad multivitamin and mineral built around ginkgo biloba, with phosphatidylcholine and phosphatidylserine from soya, L-arginine, and iron, zinc and iodine. Boots Sharp Mind is built the same way: a full multivitamin and mineral with ginkgo extract, plus CoQ10, glutathione, L-arginine and glutamine.
Look at what those two lean on in their own wording and you find zinc, iodine and iron for cognitive function, pantothenic acid for mental performance, B6 and B12 for tiredness and fatigue. That is not a coincidence and it is not a limitation — it is the only structure available to anyone, and the biggest brands in the country have arrived at it.
The trade-off: you are usually buying a whole multivitamin. If you already take one, you are paying twice for the same iron and vitamin D, and the botanical content is typically a small part of the tablet.
The single-botanical tablet
Best for: someone who has specifically decided they want ginkgo, and wants it cheaply.
Boots and most supermarkets sell a plain ginkgo biloba 120mg tablet in a 90-tablet, three-month pot. Simple, cheap per day, and easy to compare.
The trade-off, stated plainly: nothing on that label carries an authorised claim, so there is genuinely nothing the seller may tell you it does. You are buying on your own reading of the research, which is a perfectly reasonable thing to do — as long as you know that is what you are doing.
The DHA-led formula
Best for: someone who wants the one omega-3 claim that exists.
There is an authorised claim here, and it is a good one: DHA contributes to the maintenance of normal brain function. But it comes with a condition attached — the product must provide 250mg of DHA per day, DHA alone, not 250mg of EPA and DHA combined. That condition disqualifies most formulas that mention DHA at all.
Efamol Active Memory is the obvious UK example that clears it: 250mg of DHA per capsule from high-strength fish oil, alongside ginkgo, soya phosphatidylserine, vitamin E, B12 and folic acid.
Where that leaves us, since you should hear it from me rather than find it out: our own formula contains 50mg of DHA, which is a fifth of the threshold. We do not attach the brain claim to it and neither should anyone else at that dose. If a 250mg DHA claim is the specific thing you are shopping for, buy the product that reaches it. Ours is built on six nutrients that carry claims of their own, and the DHA is there because it is a useful thing to have in a vegan formula — ours comes from algae rather than fish, which is the only way a DHA supplement stays vegan at all. Efamol's is fish oil in a bovine gelatin capsule.
The premium stimulant-free stack
Best for: people who want a large ingredient list and no caffeine.
Mind Lab Pro is the best-known of these in the UK. It markets itself as stimulant-free and caffeine-free, built around Citicoline as Cognizin®, lion's mane and bacopa monnieri. That is the brand's own positioning rather than an independent assessment, and I would treat it as such — but the stimulant-free choice is a real one and for some people it is the right one.
The trade-off: it is one of the more expensive ways to buy this category, and the ingredients it is built on are precisely the ones with no authorised claim. You are buying a formulation philosophy.
Six things to check before you buy
- Is the serving one capsule or two? This is the single biggest trap in the category. A 60-capsule pot is two months at one a day and one month at two. Work out the cost per day, not per pot, before you compare anything.
- Is every ingredient printed at its own weight? A "proprietary cognitive blend — 1,200mg" tells you nothing. It could be 1,150mg of rice flour. If a brand will not itemise, assume there is a reason.
- Is there caffeine, and is it a declared number? Guarana and green tea both contribute caffeine and are frequently used to add stimulant content without the word appearing on the front of the pot. If you are caffeine-sensitive, read the ingredients list, not the marketing.
- Which nutrients actually reach 15% NRV? A label listing eleven vitamins where three reach the threshold is selling you a list, not a formula. The %NRV column is the honest one.
- Is the extract equivalent explained? "1000mg ginseng" usually means equivalent weight from a concentrated extract. That is a normal and legitimate convention — but only comparable when both products state it.
- Check the allergens. Soya turns up in this category more than any other, because phosphatidylserine and phosphatidylcholine are usually soya-derived. Neuromind, Efamol and our own formula all contain it.
How to spot a seller worth trusting
The claims rules are the most useful tell you have, and they cost you nothing to use.
If a brain supplement promises you focus, memory, mental clarity or sharper thinking, that seller is going beyond what the register permits. It is worth wondering what else they are relaxed about — dosing, sourcing, allergen declaration, whether the number on the front is the amount in the capsule or the equivalent weight.
Conversely, a label that says "zinc contributes to normal cognitive function" and stops there is not being timid. It is telling you it knows where the line is.
What we sell, and the case for it
Our Nootro Brain is a 24-ingredient formula at £29.99 for 60 capsules. The serving is two capsules, so a pot is a month and it works out at almost exactly £1 a day.
Six of the twenty-four carry authorised claims, which is the whole argument for it:
- Zinc (3mg, 30% NRV) and iodine (45µg, 30% NRV) contribute to normal cognitive function.
- Pantothenic acid (8mg, 134% NRV) contributes to normal mental performance.
- Vitamin B12 (400µg), folic acid (200µg, 100% NRV) and niacin (10mg) contribute to normal psychological function and to the reduction of tiredness and fatigue.
- Vitamin B12, niacin and iodine contribute to the normal functioning of the nervous system.
The other eighteen are there to be described, not claimed for, and every one of them is printed at its own weight: Korean panax ginseng 1000mg, guarana 400mg, bacopa monnieri 300mg, ginkgo leaf 300mg, cinnamon 300mg, turmeric root 212mg providing 10mg of curcuminoids, green tea leaf 200mg, rosemary 100mg, plus L-theanine, L-tyrosine and N-acetyl L-carnitine at 100mg each, 50mg of algae DHA, choline, phosphatidylcholine, phosphatidylserine, bamboo silica and black pepper. No blend totals.
The caffeine is declared: 100mg per serving, roughly a strong coffee, with guarana and green tea adding more on top. Most of this category is coy about that. We print the number because you cannot sensibly manage your daily caffeine against a formula that hides it.
Vegan, Halal and Kosher certified, made in the UK to GMP standards. Contains soya. Please read the caffeine note and the medication cautions in the How to take it tab before ordering.
Who should not buy it
Worth saying out loud, because a formula this size is not for everybody:
- If you are caffeine-sensitive or you already drink a lot of coffee, 100mg per serving on top of that may be more than you want.
- If you are pregnant or breastfeeding, this is not for you.
- If you take blood-thinning or blood-glucose medication, ginkgo and panax ginseng both have recognised interactions — speak to your GP or pharmacist first, and stop well before any surgery.
- If you already take a multivitamin, check the overlap before adding another source of zinc and iodine.
- If it is specifically 250mg of DHA you want, buy a product built for that.
