Stress & nervous system

Vitamin B6, vitamin B12 and magnesium, which carry the EU claims on your nervous system, with ashwagandha, rhodiola and phosphatidylserine, which carry none. It is a morning base formula taken in 8-week cycles with a break in between. It is not a sedative, and it is not a treatment for anxiety.

WHAT IS IN IT

Six 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

Three of these six 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. B6, B12 and magnesium are on the list. Ashwagandha, rhodiola and phosphatidylserine are not, and we would rather show you that than write a sentence that sounds the same for all six.

Vitamin B6

AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

“Vitamin B6 contributes to normal psychological function.”

Regulation (EU) 432/2012, on condition that a dose is at least a source of vitamin B6 under Regulation (EC) 1924/2006. This formula carries 1.4 mg, exactly 100% of the NRV, as P5P, the active form. B6 also carries the claim on normal functioning of the nervous system. Its upper limit is 12 mg a day, one of the lowest among the vitamins, and it is in five other VION formulas, so your B6 is counted across your whole plan.

Vitamin B12

AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

“Vitamin B12 contributes to normal psychological function.”

Regulation (EU) 432/2012, under the same condition. This formula carries 10 µg, 400% of the NRV, as methylcobalamin, the active form that needs no conversion. B12 also carries the claim on normal functioning of the nervous system. EFSA has not set an upper limit for it. If you take metformin or a proton pump inhibitor long term, tell your doctor: both can lower your B12.

Magnesium

AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

“Magnesium contributes to normal functioning of the nervous system.”

Regulation (EU) 432/2012, under the same condition. It is the claim this formula is built around. The dose is 200 mg, 53% of the NRV, as bisglycinate, the form our notes prefer because it is gentle on the gut. Magnesium also carries the claim on normal psychological function. The upper limit for magnesium from supplements is 250 mg a day, so 200 mg leaves little room for any other formula that carries it.

Ashwagandha

NO AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

Nothing. Ashwagandha has no authorised EU claim, so we attribute no effect to it.

It is here because the standard trials on stress used 300–600 mg a day of standardised root extract for 8 weeks. This formula uses 300 mg, the low end of that range and half the 600 mg our dose table records as the minimum effective amount. That is a reason to include it, not a permission to promise anything. It is still a candidate ingredient for us rather than an approved one: the liver-safety data of the extract we use is still being verified, and a clinician has to sign it off before this formula ships. Rare cases of liver injury are documented, Denmark restricts its free sale and Sweden and Finland require warnings, and France's food safety agency, ANSES, advises against it in pregnancy, breastfeeding, under 18, thyroid disorders, hyperandrogenism, liver disease, heart disease and with sedatives. Every one of those rules this formula out.

Rhodiola

NO AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

Nothing. Rhodiola has no authorised EU claim, so we attribute no effect to it.

It is here on a systematic review of randomised trials (Hung 2011) and a placebo-controlled trial of a standardised extract (Olsson 2009). The dose is 200 mg. That is the bottom of the 200–600 mg a day range in our library, below the 600 mg our dose table records as the minimum effective amount, and below the 300–600 mg a day the ESCOP monograph uses. We would rather say so than let the name do the work. Taken late in the day it can disturb sleep, which is one reason this formula stays in the morning. It can add to the effect of antidepressants on serotonin.

Phosphatidylserine

NO AUTHORISED CLAIM

WHAT WE ARE ALLOWED TO SAY

Nothing. EFSA reviewed its claims on cognition and stress and turned them down.

It is here as a building block of nerve cell membranes, at 100 mg. That is below the 300–400 mg a day our library lists for it, and we would rather say so than let the name do the work. It is usually made from soy.

HOW IT IS POURED

Six pulses. Not always six.

The full dose of this formula is 1.2 ml, which the device serves as six pulses of 0.2 ml. On a morning when your band says you do not need the whole thing, it pours four and tells you why. A pressed pill has one setting. This has six.

TONIGHT'S POUR

MORNING

Why then

It is a daytime formula, and our note on the window says why: ashwagandha, rhodiola, phosphatidylserine, B6 and B12 are placed in the day, and the night is ruled out because ashwagandha can be activating. Rhodiola points the same way, because taken late it can keep you awake. Two things in our library pull against that. Magnesium bisglycinate is the form our notes usually put at night, and the ashwagandha page allows the morning or the evening depending on the goal, with our interaction record calling it the calming half of the pair it forms with rhodiola. The formula keeps the morning, and we would rather show you where our own notes disagree than pretend they do not.

WITH BREAKFAST

Why with food

Ashwagandha is easier on the stomach with a meal, and so is B6. Magnesium bisglycinate is well tolerated either way, so it does not decide the timing.

45 ML CARTRIDGE

How long it lasts

At the full 1.2 ml it is 37 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 CORE formula is not suggested. It is assigned.

CORE is the part of your plan that stays still on purpose. It comes out of your questionnaire, not out of yesterday's data, and it is held long enough for a change to actually mean something. This one also stops on purpose.

  1. 01

    It comes from your questionnaire

    Your answers put this formula in your base, and the same answers check it against liver, thyroid, heart and autoimmune conditions, hyperandrogenism, pregnancy and breastfeeding, your age and sedative medication before it is assigned. No wearable data is needed for that first decision.

  2. 02

    It is held for 8 weeks

    That is the length of the standard ashwagandha trials behind it. Nothing about the recipe moves inside that window.

  3. 03

    Only the amount moves, morning by morning

    Once it is in, the engine adjusts how much of the 1.2 ml you get, in 0.2 ml steps, from your stress score and HRV of the last few days. The recipe itself does not change.

  4. 04

    At 8 weeks, it is reviewed and it pauses

    You repeat a perceived-stress test (PSS-10) or a morning cortisol test, plus TSH if your thyroid is a concern and liver enzymes if your liver is. Then the formula stops for 4 weeks. It can run up to three cycles a year, so no more than 24 weeks of ashwagandha. The break and the cap are our own clinical rules, not numbers set by a regulator: ANSES only advises against long use of ashwagandha without medical supervision.

SAFETY AND INTERACTIONS

What it is counted against.

Every pair of ingredients in our library is checked against the others before a plan is built. This is what that check does for this formula.

COUNTED ACROSS FORMULAS

Ashwagandha

Chronic cortisol, Low testosterone and Daily athletic each carry 600 mg of ashwagandha. Our library puts an informal safety ceiling of 600 mg a day on it, so any of them next to the 300 mg here would pass it. The engine adds up your ashwagandha across every formula you take and blocks a new one once the total reaches 1,200 mg a day, or once you have taken it for 90 days without a break. That blocking threshold sits above the informal 600 mg ceiling, so 300 mg here plus 600 mg elsewhere would not be stopped automatically. Our library also flags ashwagandha and rhodiola in the same dose as a timing precaution, one being activating and the other calming, and the record says to split them between morning and night rather than combine them. This formula does combine them, at the low end of both doses. That is one of the points its clinical review has to settle.

COUNTED TOGETHER

Magnesium and vitamin B6

Nine other VION formulas carry magnesium, from 100 to 200 mg. Any one of them on the same day as this one would pass the 250 mg upper limit for supplemental magnesium, so the engine will not add it. B6 is in five other formulas and is counted the same way, against 12 mg a day.

TALK TO A DOCTOR FIRST

Not for everyone

Do not take it if you have liver disease or raised liver enzymes, a thyroid disorder (including an overactive thyroid or Graves' disease), hyperandrogenism, heart disease, an autoimmune condition, advanced kidney disease or myasthenia gravis (high doses of magnesium can worsen muscle weakness); if you are pregnant, breastfeeding or under 18; if you have bipolar disorder; if you take levodopa for Parkinson's without carbidopa, because the B6 in this formula lowers how well it works; or if you take sedatives such as benzodiazepines, psychiatric medication (especially SSRIs), immunosuppressants, or drugs that can harm the liver such as paracetamol, isoniazid or methotrexate. Ashwagandha also adds to the sedative effect of alcohol, as it does with sedatives. Stop it at any sign of liver trouble: yellowing skin, unusual tiredness, abdominal pain. Ask a doctor first if you have a heart rhythm problem or heart block, high blood pressure, peripheral neuropathy, polycythaemia vera, histamine intolerance or cancer; if you have surgery planned (stop 2 weeks before); or if you take other antidepressants (SNRIs, MAOIs), stimulants such as caffeine or synephrine, thyroid hormone (keep magnesium 4 hours away from levothyroxine), anticoagulants, diabetes or blood pressure medication, calcium-channel blockers, diuretics, digoxin, cycloserine, isoniazid, anticonvulsants, hydralazine, penicillamine, oral contraceptives or theophylline (all four lower your B6), chloramphenicol or colchicine (both lower your B12), bisphosphonates or tetracyclines (keep them at least 2 hours away from the magnesium), quinolone antibiotics (take those 2 hours before the magnesium or 4 to 6 hours after it), aminoglycoside antibiotics or amphotericin B (both increase the magnesium you lose through the kidneys), muscle relaxants, cancer treatment, or long-term metformin, PPIs or H2 blockers. Tell your anaesthetist about the B12 before any surgery using nitrous oxide, which inactivates it. Rhodiola also affects the CYP2C9 and CYP3A4 enzymes in laboratory work, so mention it if you take several medicines at once. This is what our library documents for these six ingredients, not a complete list of every drug they could interact with: each ingredient has its own page with the full record. Contains soy unless the label says otherwise. Do not exceed the daily dose, keep out of reach of young children, and do not use it in place of a varied, balanced diet. The app asks before it ever assigns this one.

WHERE IT COMES FROM

You can check every line of this page.

These are the sources this page leans on: the regulation that lets us make three of the claims, the EFSA opinion that turned down a fourth, the French safety opinion behind the ashwagandha exclusions, the fact sheet behind the 8-week cycle, the two upper limits we stay under, and the two rhodiola trials. It is not the whole file for these six ingredients, which each carry their own list on their own page.

WHAT IS NOT PROVEN YET

This formula has not completed clinical validation. Three of its six ingredients rest on an authorised EU claim at the dose used. Ashwagandha and rhodiola rest on published trials alone, and phosphatidylserine on no claim at all, because EFSA turned its claims down. 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
