*Reference Intake (RI) for an average adult **No RI established
Reference Intake (RI), also called the Nutrient Reference Value (NRV), is a single general figure for an average adult, set under UK food-labelling rules so products can be compared like for like. It reflects an amount considered enough for the great majority of healthy people rather than a personalised or optimal target, which is why supplement levels are often shown as a high percentage of the RI. Individual needs vary, so use the RI as a guide alongside a varied, balanced diet.
Suggested Use: Take 1 tablet daily, preferably with a meal.
Our active ingredients are backed by 200+ published clinical studies, including 135 randomised controlled trials and 29 meta-analyses. We choose every active for the research behind it, not because it is on trend. Here are a few of the studies on the B vitamins and active forms we use.
In the FACIT trial, 818 older adults took 800µg of folic acid every day for 3 years and scored on memory tests like people about 4.7 years younger than their age. Folate only helps if the body can use it, which is why we deliver it as L-5-MTHF (methylfolate), the active form, rather than folic acid. Folate contributes to normal psychological function.
Durga J et al. The Lancet, 2007.
In a double-blind trial, healthy adults taking a daily vitamin supplement for 12 months reported better mood than those on placebo, measured across the whole group. Mood relies on B vitamins like B6, folate and B12, which we include in their active forms (P5P, methylfolate and methylcobalamin). B6, folate and B12 contribute to normal psychological function.
Benton D et al. Neuropsychobiology, 1995.
Benfotiamine is a fat-soluble form of thiamine (B1) that the body takes up far more easily than the standard thiamine used in most supplements. In a pharmacokinetic study it raised blood thiamine to around 11 times the level from standard thiamine hydrochloride. That superior absorption is why we use it in place of the cheap thiamine salts most supplements rely on.
Pharmacokinetic study, benfotiamine vs thiamine hydrochloride, 2014.
In the University of Oxford VITACOG trial, older adults with mild cognitive impairment who took B vitamins (folate, B6 and B12) showed on average around 30% less brain atrophy over two years than those given a placebo, with the greatest benefit in those with raised homocysteine.
Smith AD et al. PLoS ONE, 2010.
Many people carry a common variation in the MTHFR gene that slows how they process folate. In a double-blind trial, riboflavin (vitamin B2) lowered homocysteine in people with this 677TT gene type, by about 22% across the group and by as much as 40% in those who started with lower riboflavin levels. We include riboflavin as its active R5P form. Riboflavin and folate contribute to normal homocysteine metabolism.
McNulty H et al. Circulation, 2006.
A meta-analysis pooling 25 randomised trials found folic acid lowered homocysteine by about 23%. We deliver folate (vitamin B9) as L-5-MTHF (methylfolate), the active form the body uses directly, without the conversion step folic acid needs. Folate contributes to normal homocysteine metabolism.
Wald DS et al. Am J Clin Nutr, 2005.
You sleep, but still wake up tired. The afternoon drags, and by the evening there is not much of you left.
Tired is not a personality trait
Your body cannot use food as energy straight away. It has to be converted first, and that conversion runs on B vitamins.
The science is simple: without B vitamins, your body cannot release the energy in your food.
One small tablet, once a day, holding all eight B vitamins: thiamine as benfotiamine, riboflavin as riboflavin-5-phosphate, niacin as niacinamide, pantothenic acid, B6 as pyridoxal-5-phosphate, biotin, folate as L-5-MTHF, and B12 as methylcobalamin. Made in Britain. Plans from 50p a day.

FACIT, double-blind, 818 adults
memoryIn the FACIT trial, 818 older adults took 800µg of folic acid every day for 3 years and scored on memory tests like people about 4.7 years younger. Our formula provides folate (vitamin B9) too, but as L-5-MTHF (methylfolate), the active form the body can use directly without first converting it. Folate contributes to normal psychological function.

Benfotiamine PK study, vs thiamine HCl
energyBenfotiamine is the fat-soluble derivative of thiamine, and the body takes it up far more easily than the cheap thiamine used in most supplements. In a pharmacokinetic study it raised blood thiamine to roughly 11 times the level from standard thiamine hydrochloride (a relative bioavailability of 1147%). It's the form we use, chosen for that superior absorption.

less brain shrinkage
over 2 years
Oxford VITACOG, double-blind
brainIn Oxford University's VITACOG trial, older adults with raised homocysteine took folic acid, vitamin B6 and B12 for 2 years and had about 30% less brain shrinkage than those on placebo. Our formula includes the same three B vitamins, folate (B9), B6 and B12, in their active forms (methylfolate, P5P and methylcobalamin). These B vitamins contribute to normal homocysteine metabolism.

We take B vitamins seriously. Our founder spent years feeling drained and let down by supplements that did not deliver, so he set out to make the best methylated B complex in Britain. Read his story.
Every batch is made in Britain, in facilities independently certified to recognised quality and food-safety standards. The health claims on this page use only EU-authorised wording, and they describe the nutrients rather than the finished product, so nothing here is overstated.
Our 4.81 rating is the whole published set, not a selection: the 4, 3, 2 and 1-star reviews are all shown too. Most were collected on our previous store and imported into Judge.me, so they are real customer words, which is why we do not badge them as verified. And the risk sits with us, not you: 90 days to ask for your money back, and a subscription you can cancel any time, with the cancellation link published openly rather than buried.
It varies from person to person, and we are not going to pretend otherwise. B vitamins are water soluble, so your body works with what you take in each day rather than storing a lot up. Consistency matters far more than any single dose.
That is why we suggest giving it three months, one tablet a day, so you can judge it properly for yourself rather than after a handful of doses. Some people write to us after a couple of weeks, others take longer, and a few tell us it was not for them.
Our guarantee runs for a full 90 days from delivery, the same length as a three-month supply, and you can open the bottles and take them. So you can give it the complete run we suggest and still change your mind.
You get your money back. Contact us within 90 days of your delivery date and we will refund your first order, whether it was a one-time purchase or a subscription.
You can open the bottles and actually take them. There is nothing to send back and no empty bottle to post, whatever the size of your order. That is the point: you cannot judge a B complex without taking it for a while, so the guarantee is built to let you.
Full terms are on our refund policy. It is a voluntary guarantee on top of your statutory UK rights, not instead of them.
We cannot give medical advice, and we would rather say that plainly than guess. If you take prescription medication, have a health condition, or are pregnant or breastfeeding, check with your GP or pharmacist before starting any supplement.
Show them the label if it helps: every ingredient and dose is listed in full on this page, so there is nothing for them to guess at either.
That is riboflavin, vitamin B2, and it is completely normal. Riboflavin is a naturally bright yellow-green pigment: its name comes from flavus, the Latin word for yellow. Ours is Riboflavin-5-Phosphate, the active form.
B vitamins are water soluble, so your body uses what it needs and passes the rest out rather than storing it. Riboflavin gives that a vivid yellow tint, usually within a few hours of taking your tablet. Doctors have a name for it, flavinuria, and it is harmless and well documented.
It is expected with any B-complex at a meaningful dose, and it is not a sign that anything is wrong. As with any supplement, if you have another symptom that concerns you, speak to your GP or pharmacist.
Take one tablet daily, ideally with a meal. Morning is a great time, as B vitamins contribute to normal energy-yielding metabolism throughout the day.
Take one tablet once daily.
Helps with absorption and reduces the chance of stomach upset.
For best results, use daily for at least 3 months.
Subscribe & Save delivers 3 jars every 3 months at 40% off, which works out at 50p a day. It is covered by the same 90-day money-back guarantee.
You can skip, change or cancel any time from your account, with no minimum term. See exactly how to cancel, in two steps, before you buy.
Prime Vitality was created from real, lived experience. Every B vitamin is in its fully active, methylated form and made in Britain in GMP-certified facilities. Many brands tend to use basic, non-active forms that your body has to convert before it can use them. We start with the forms your body can use straight away.
Methylated means the vitamins are in their active forms, which are easier for your body to recognise, absorb and use. Some people carry common gene variations that affect how efficiently they make that conversion.
Cheaper supplements tend to use non-active, basic forms that cost very little to produce. Prime Vitality uses premium active forms, like benfotiamine, methylcobalamin (B12), L-5-MTHF folate and P5P (B6), which cost more but are already in the state your body can use. You are paying for quality that reaches your cells, not fillers.
Yes. Every batch is manufactured in Britain, in facilities that are independently certified to recognised quality and food-safety standards.
Yes. Prime Vitality Methylated B Complex Ultra is fully vegan and non-GMO.
From just 50p a day, with free UK delivery and a 90-day money-back guarantee.
