Cognitive & focus

A morning booster built on 100 mg of caffeine and 200 mg of L-theanine, with citicoline, ginkgo and vitamin B5 alongside. Two of the five carry an authorised EU claim and three do not, and this page tells you which. It is a stimulant, so it is never served after 2 pm.

WHAT IS IN IT

Five actives. Nothing else.

These are the reference doses of the formula. Your device pours them in steps of 0.2 ml, so what you actually take on a given morning can sit below the reference when your data does not call for the full dose.

THE SCIENCE BEHIND IT

Two of these five have an authorised claim. Three do not.

In the EU, only a short list of health claims is authorised. Some are rejected and the rest of the register sits on hold. Here, EFSA turned down two of the ingredients and one is still waiting. We would rather show you which is which than write a sentence that sounds the same for all five.

Caffeine

AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

“Caffeine helps to increase alertness and to improve concentration”

The claim holds from 75 mg of caffeine per serving. This formula carries 100 mg, so a pour of six pulses (86 mg) still meets it and a pour of five (71 mg) does not. EFSA considers 200 mg at a time and 400 mg a day safe for healthy adults, and 200 mg a day in pregnancy and breastfeeding.

Reg. (EU) 1169/2011 + 432/2012 · EFSA Journal 2015;13(5):4102 · 8 sources on file · 2 with a PMID

L-theanine

NO AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

Nothing. EFSA reviewed its claims on cognitive function and mental stress and turned them down.

It is here because of the caffeine. 200 mg of L-theanine to 100 mg of caffeine is the best-studied pairing in our library, and the published work on it, including a 2014 meta-analysis, is about keeping the alertness while taking away some of the jitters. That is a reason to include it, not a permission to promise anything.

EFSA Journal 2011;9(6):2238 · claim rejected · 8 sources on file · 2 with a PMID

Citicoline

NO AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

Nothing. EFSA reviewed its claims on vision and on memory and turned both down.

The European Commission confirmed that rejection in Regulation (EU) 2025/2223. Your body uses citicoline to build the membranes of nerve cells. It is here at 250 mg, the bottom of the 250–500 mg range our library lists, and half the 500 mg it lists as the lowest effective dose. We would rather say so than let the name do the work.

Ginkgo biloba

ON HOLD IN THE EU REGISTER

WHAT WE ARE ALLOWED TO SAY

Nothing yet. Botanical claims are suspended pending review.

The EMA monograph covers a standardised ginkgo leaf extract as an herbal medicine, at a single dose of 120–240 mg and a daily dose of 240 mg, for at least 8 weeks. That is a medicines assessment, not a food claim. This formula carries 120 mg once a day, half that daily dose. Ginkgo slows your platelets down, which is behind most of the warnings on this page.

Vitamin B5 (pantothenic acid)

AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

“Pantothenic acid contributes to normal mental performance.”

Regulation (EU) 432/2012, for a product that is at least a source of pantothenic acid. This formula carries 6 mg, 100% of the NRV, as calcium D-pantothenate. There is no EFSA upper limit for it. It is the same 6 mg as in Energy & vitality and Chronic cortisol.

Reg. 432/2012 · EFSA Journal 2009;7(9):1218 and 2010;8(10):1758 · NRV 6 mg

HOW IT IS POURED

Seven pulses. Not always seven.

The full dose of this formula is 1.4 ml, which the device serves as seven pulses of 0.2 ml. On a morning when a lighter dose is set, it pours six and tells you why. Six pulses still carry 86 mg of caffeine, above the 75 mg the claim needs. No wearable rule adjusts this formula yet, so that lighter dose is a decision, not a reading. A pressed pill has one setting. This has seven.

TONIGHT'S POUR

MORNING, NEVER AFTER 2 PM

Why then

Caffeine stays in your blood for about five hours, and taken within six hours of bed it can cut into your sleep. So this formula goes out with your morning window and is never served after 2 pm.

WITH FOOD, PREFERABLY

Why with breakfast

Ginkgo is meant to be taken with food. Food slows how fast you feel the caffeine, not how much of it you get, and L-theanine and B5 work with or without a meal.

45 ML CARTRIDGE

How long it lasts

At the full 1.4 ml it is 32 mornings. At a partial pour it lasts longer, so the app orders your refill from what you actually took.

HOW IT ENTERS YOUR PLAN

A BOOST formula is not assigned. It is suggested.

BOOST is the part of your plan that comes and goes, on top of your base. This one carries an open question we would rather put here than in small print: the caffeine works within the hour, but the ginkgo in it is documented for courses of at least 8 weeks. A clinician still has to decide how long this booster should run.

  1. 01

    It is suggested from your questionnaire

    Intellectual work, or concentration as one of your goals, is what brings it up. No wearable signal that calls it in has been defined yet. The same answers keep it away from you if you are pregnant, breastfeeding, under 18, have heart disease or take a vitamin K antagonist.

  2. 02

    For a day or two, it is the caffeine working

    Used on the morning of a demanding task, what you get is the caffeine and the L-theanine, which act within the hour. The evidence on ginkgo does not apply to use that short, and we do not borrow it.

  3. 03

    As a course, it runs for 8 weeks

    That is the minimum the EMA monograph sets for the ginkgo extract, and it is the course on file: 56 days. Citicoline and B5 are there for that longer run, not for the morning itself.

  4. 04

    At three months, it is reviewed

    If nothing has improved after three months, or things get worse, it stops. Courses can be repeated after that review. No official source we found sets a break between courses or a yearly limit, so we do not invent one.

SAFETY AND INTERACTIONS

What it is counted and checked against.

Every pair of ingredients in our library is checked against the others before a plan is built. Inside this formula, one of the ten possible pairs is documented: caffeine with L-theanine, a pairing our library recommends at this 2:1 ratio. Outside it, caffeine is kept at least 8 hours from the sedatives in the night formulas and an hour away from Iron, and it is capped at 75 mg next to the rhodiola in Chronic cortisol. Three more caffeine pairs are on file: next to the 200 mg of ginseng in Acute energy the caffeine is monitored and may be cut by 25–30%; it is not co-formulated at a high dose with the echinacea in Immunity and Acute immunity, which raises your caffeine exposure by about 30%; and the calcium in Bones & joints is monitored, without exclusion, above 300 mg of caffeine a day. L-theanine adds up too: Sleep & circadian rhythm carries the same 200 mg, and the two together would sit at 400 mg, past the 250 mg a day upper limit our library holds for it. The engine's accumulated upper-limit rule does not list L-theanine today, so we say it here rather than leave it out.

COUNTED ACROSS FORMULAS

Acute energy · Pre-workout

Both carry caffeine too: 75 mg and 150 mg. The engine adds up caffeine from every formula in your plan. From 200 mg a day you are told, and at 400 mg, the EFSA upper limit, the addition is blocked. Next to this one, Pre-workout alone takes you to 250 mg.

BLEEDING RISK FLAGGED

Anti-inflammatory & recovery

That formula carries 500 mg of curcumin. Ginkgo and curcumin both slow your platelets down, and our library only pairs them below 120 mg of ginkgo and 100 mg of curcumin, which these doses are not. The same goes for Systemic inflammation and Muscle damage (CK), which carry the same 500 mg. The rule reaches further than curcumin: it also covers the 100 mg of resveratrol in Oxidative cardiovascular and in Systemic inflammation, and the 15 mg of vitamin E in Liver. Ginkgo with resveratrol is a documented pair, flagged hard if you are on anticoagulants or antiplatelets. Any plan with two such ingredients is flagged for bleeding risk, and blocked if you are on anticoagulants.

TALK TO A DOCTOR FIRST

Not for everyone

Not for you if you are pregnant or breastfeeding, under 18, have heart disease or a symptomatic heart rhythm problem, haemophilia or another bleeding disorder, epilepsy or a history of seizures, an anxiety or panic disorder, reflux or a peptic ulcer, or an allergy to ginkgo. Do not take it with an anticoagulant — a vitamin K antagonist such as warfarin or acenocoumarol, or dabigatran, apixaban or heparin — or with an antiplatelet such as aspirin, clopidogrel or ticagrelor: ginkgo slows your platelets down, and our library rules that combination out rather than flagging it. It is also not recommended together with efavirenz. Ask a doctor first if you take NSAIDs, anticonvulsants, an MAO inhibitor, theophylline, lithium, clozapine, SSRIs or SNRIs, trazodone, sedatives or sleeping pills, nifedipine or another calcium-channel blocker, blood pressure or diabetes medication, thiazide diuretics, quinolone antibiotics, the contraceptive pill, beta-agonists or decongestants such as pseudoephedrine, or levodopa for Parkinson's disease; or if you have glaucoma, low blood pressure, liver or kidney disease, histamine intolerance or a cashew or pistachio allergy, or are in cancer treatment. Glaucoma is listed as a caffeine contraindication in our library at the level of a precaution, which is why it sits in this second list and the anxiety and the reflux sit in the first. Stop it at least two weeks before planned surgery. Caffeine can cause nervousness, insomnia and palpitations: keep your total from every source to no more than 400 mg a day. Do not exceed the dose, do not use it in place of a varied diet, and keep it out of reach of young children. The app asks before it ever suggests this one.

WHAT IS NOT PROVEN YET

This formula has not completed clinical validation. Its five ingredients rest on published work and, in two cases, on an authorised EU claim, but the combination itself has not been tested by us in a trial. When it is, the result goes on this page, whatever it says.

YOU DO NOT PICK YOUR FORMULAS
