Citicoline Supplement UK: Where to Actually Find CDP-Choline

If you have been hunting for a citicoline supplement in the UK and coming up mostly empty, you are not imagining it. Citicoline is legal here, it is a fully authorised novel food, and it is sold by a handful of specialist retailers, small UK manufacturers, imported American brands and a growing number of nootropic drinks. What it is not is easy to find. You will rarely see a citicoline supplement on a high street shelf, the choice is a fraction of what an American shopper gets, and UK labels tend to say very little about it. This post explains what citicoline is, why the UK market is so thin, exactly what the regulator allows, the forms you can actually buy here, and the three things worth checking before you spend anything.

What citicoline actually is

Citicoline is the common name for cytidine 5'-diphosphocholine, usually shortened to CDP-choline. It is a molecule your own cells make, and it sits on the pathway that builds phosphatidylcholine, one of the main structural fats in cell membranes.

Taken by mouth, it does something slightly unusual. A 2019 review in Nutrients, Citicoline: A Superior Form of Choline? by Synoradzki and Grieb, reports that citicoline is thought to be absorbed intact, with hydrolysis occurring in the liver, where it splits into choline and cytidine, though the authors are careful to note that the particulars are not fully settled. Those two then enter separate metabolic routes. That is the mechanical difference between citicoline and a plain choline salt, and it is why the two are not interchangeable on a milligram-for-milligram basis.

If you want the fuller comparison against choline bitartrate and alpha-GPC, we have written that up separately in citicoline vs choline vs alpha-GPC.

Why citicoline is scarce in the UK

Three things stack up.

It is a novel food, not a vitamin. Citicoline did not have a history of significant consumption in Europe before 1997, so it had to go through novel food authorisation before anyone could sell it. Kyowa Hakko carried that application, EFSA published a safety opinion in October 2013, and the European Commission authorised it via Commission Implementing Decision 2014/423/EU on 1 July 2014. That authorisation carried across into GB law at the end of the transition period and now sits on the FSA's register as NOVEL-34, authorised in England, Scotland and Wales. Novel food status means paperwork, conditions and a ceiling, all of which deters smaller brands.

There are no authorised health claims to sell it on. This is the big one commercially. UK and EU law only lets you make health claims from an approved register, and citicoline has none. A memory claim was put forward and rejected. On 4 July 2024 EFSA published its opinion on 'Citicoline' and support of the memory function, assessing whether citicoline supports memory in middle-aged and elderly people with age-associated subjective memory impairment, and concluded that a cause and effect relationship had not been established. The European Commission then formally refused the claim in EU law through Commission Regulation (EU) 2025/2223 of 4 November 2025. GB did not adopt that regulation, but the practical position here is the same: there is no authorised citicoline claim on the GB register. So a UK brand can put citicoline in a product and name it on the label, but it cannot legally tell you what it is for. That makes it a hard ingredient to build marketing around, and most mainstream brands simply do not bother.

Worth knowing: choline itself, as a nutrient, does have three authorised claims in the register covering normal lipid metabolism, maintenance of normal liver function and normal homocysteine metabolism. But those claims require at least 82.5mg of choline per 100g, per 100ml or per single portion, and citicoline is only about a fifth choline by weight. A 250mg or 300mg serving therefore delivers well under that threshold, so the smaller citicoline products cannot borrow the choline claims either. Hence the silence on UK labels.

The US market has no equivalent brake. Under American supplement rules, structure-function claims are far easier to make, so citicoline became a mainstream focus ingredient there. Kyowa Hakko's branded version, Cognizin, now appears in more than 200 supplements and functional beverages, mostly American. UK shoppers see the shadow of that market through imports and social media without having the same shelf to buy from.

What the UK regulator actually permits

This is the single most useful number to carry with you. Under the GB novel food authorisation, citicoline in food supplements for adults is capped at 500mg per day. A separate allowance of 250mg per serving, up to 1,000mg a day, applies only to foods for special medical purposes, which is a different regulated category and not something you buy off a shelf for general use.

The authorisation also requires that the ingredient is designated as "Citicoline" on the label, and that the product carries a statement that it is not intended to be consumed by children.

Two practical consequences. First, any UK-facing supplement offering you more than 500mg of citicoline a day for general use is outside the authorised conditions, and that tells you something about how carefully the rest of the product was put together. Second, a 500mg daily serving is at the legal ceiling, not a bonus. We go deeper on how the studied doses map onto that ceiling in citicoline dosage.

The forms you can buy in the UK

On the capsule side, the UK options tend to be either imported American brands such as Jarrow Formulas at 250mg per capsule, sold through several UK health retailers, or smaller UK manufacturers. Herb-ology sells a UK-made vegan citicoline marketed as 500mg, which on the label is 250mg per capsule across a two-capsule daily serving, a neat illustration of why the per-serving check below matters. British Supplements lists 305.1mg of CDP-choline per capsule alongside a 34.6mg uptake blend. Mind Nutrition sells 250mg capsules, with a Cognizin powder listed separately. At the time of writing, a month's supply of capsules generally lands somewhere around £13 to £35 depending on strength, capsule count and whether it uses a branded form, though prices move and it is worth checking directly.

The drinks route has grown fastest, though the doses are not consistent. Neutonic, a UK brand, uses 500mg of Cognizin citicoline with 120mg of caffeine per 330ml can. American brands including C4 Smart Energy and POW! Energy also use Cognizin, though the amount per can is not always declared on the label or the product page. That is a genuine option if you want caffeine anyway. If you do not, or if you are also taking creatine, it is worth reading creatine and caffeine before you make a drink your daily source.

Three things to check before you buy

1. Dose per serving, not dose per bottle. Front-of-pack numbers are often the per-capsule figure while the serving size is two capsules, or the reverse. Find the "per serving" column on the nutrition panel and check how many capsules that serving is. Then check it against the 500mg daily ceiling.

2. Whether it is actually citicoline. "Choline" on a label can mean choline bitartrate, choline citrate, alpha-GPC or citicoline, and they are different molecules at very different price points. The GB authorisation requires the designation "Citicoline", so if the label only says choline, it is not citicoline. Branded forms such as Cognizin will name themselves; generic citicoline is not automatically worse, but it should still be clearly declared with a specific milligram figure.

3. No proprietary blends. If citicoline appears inside a blend with a single combined weight for the whole blend, you cannot know how much you are getting. Given citicoline is one of the more expensive ingredients in a nootropic formula, that ambiguity rarely works in your favour.

What the research actually says, and what it does not

Being honest about this matters more than usual, because the gap between what the internet claims and what the evidence supports is wide.

The most cited human trial in healthy people is Nakazaki and colleagues, published in The Journal of Nutrition in 2021. One hundred healthy adults aged 50 to 85 with age-associated memory impairment took either 500mg a day of citicoline or placebo for 12 weeks. The citicoline group showed significantly greater improvement on a paired associate memory test and on a composite memory score, and the supplement was reported as safe and well tolerated. A separate randomised trial of a citicoline-caffeine beverage in 60 healthy adults reported improvements in measures of concentration, working memory and sustained attention, though that design cannot separate citicoline from caffeine.

Set against that, EFSA reviewed the memory dossier in 2024 and did not consider the evidence sufficient to establish cause and effect, noting among other things that the 500mg finding was not replicated in a study using a higher dose. Both of those things are true at once. Individual trials have reported findings; the regulator's evidentiary bar for a population-wide claim has not been met. Anyone telling you citicoline is proven to improve your memory is overstating it, and anyone telling you there is no research at all is understating it.

Where perco fits

We built perco partly because of the gap this post describes. It is a single unflavoured daily stick combining 5g of creatine monohydrate with 300mg of citicoline, plus zinc and vitamins B5, B6 and B12 at 100% NRV, made in the UK, caffeine-free and vegan. The 300mg sits deliberately inside the authorised 500mg ceiling and in the range used in published research, and it is declared as a specific number rather than hidden in a blend. Our reasoning for pairing the two ingredients in one dose is set out in creatine and citicoline together.

We are not on sale yet. perco launches in late 2026 at £34 for a 30-stick box, or £24 on subscription, and the first 100 founding members on the waitlist lock that founding price permanently. Until then, the retailers above are your realistic options, and we would rather tell you that plainly than pretend otherwise.

Frequently asked questions

Is citicoline legal in the UK? Yes. Citicoline is an authorised novel food in England, Scotland and Wales, listed on the FSA's register as NOVEL-34. Food supplements for adults are permitted up to 500mg per day, and labels must designate the ingredient as "Citicoline" and state that the product is not intended for children.

Can I buy citicoline in Holland & Barrett or Boots? Citicoline is not a reliable high street find in the UK. Availability at the large chains varies and it is often absent entirely, which is why most UK buyers end up ordering from specialist online retailers, smaller UK manufacturers or nootropic suppliers. It is always worth checking a specific store's current range directly.

Is CDP-choline the same as citicoline? Yes, they are the same compound. Citicoline is the shortened name for cytidine 5'-diphosphocholine, and CDP-choline is the abbreviation of the chemical name. UK labels are required to use the designation "Citicoline", so you will often see both terms used together on the same product.

How much citicoline should I look for per serving? Published trials in adults have commonly used 250mg or 500mg per day, and the GB authorisation caps food supplements at 500mg daily for adults. That gives you a sensible window to shop within. Anything well below 250mg is unlikely to reflect the studied range, and anything above 500mg a day exceeds the authorised conditions for general supplements.

Why do UK citicoline products not explain what they do? Because they legally cannot. There are no authorised health claims for citicoline in GB or EU law, EFSA declined to establish a cause and effect relationship for a memory claim in 2024, and the European Commission formally refused that claim in 2025. Brands can name the ingredient and state the dose, but they cannot tell you what it is for. That silence is a compliance requirement, not a sign the ingredient is unstudied.

Can I take citicoline with creatine? We are not aware of any reason the two cannot be taken together, and they are increasingly combined in single products because their formats suit each other, both being unflavoured powders. Neither is a stimulant. If you are new to creatine, our guides on when to take creatine and is creatine safe cover the practical questions first.
