Boots sleep supplements review: is it worth it for lifters?

One shelf, two counters: the pharmacy counter's licensed sleep aids and what they do to a lifter's next day, and the supplement aisle's three kinds of product and what each may lawfully say

A high street pharmacy chain's sleep products are reviewed here as what they actually are, which is two counters rather than one shelf, because a pharmacy sells sleep in two legal categories that sit yards apart and are confused by every search that lumps them together as sleep supplements. The first counter is the pharmacy counter, behind which the sedating antihistamine sleep aids sit: diphenhydramine and promethazine, licensed pharmacy medicines sold after a pharmacist's questions, which is the first fact about them, since a product that requires a pharmacist's questions is a medicine with a licence, an indication and a limit, and not a supplement at all. Their licence is for short-term use, and the reasons are specific to a lifter. They sedate by blocking histamine in the brain, which produces sleep onset and also next-day drowsiness that lasts into a morning session, slows reaction time on a drive to the gym and drags a working set; they have anticholinergic effects, a dry mouth and, in older users, worse; and tolerance to the sedation arrives within days of nightly use, so that a lifter who takes one every night for a fortnight has, by the end of it, a habit without a sleep aid and a worse night when it stops. For three nights of a specific disruption, a shift change, a flight, a bereavement, the pharmacy counter is the right counter and the pharmacist will say so; for a lifter who sleeps badly in general, it is the wrong one and the pharmacist will say that too.

The second counter is the supplement aisle, and it holds three kinds of product that may say three different things. The first kind is the food supplement, magnesium above all, which may carry only the authorised claims for its nutrient, and magnesium's are normal nervous system function, normal psychological function, normal muscle function and the reduction of tiredness and fatigue; there is no authorised claim about sleep for any nutrient, so an aisle magnesium sold for sleep is sold on an implication its label may not make, and is read for what the label actually says and for its elemental dose, form, pence per day and testing like any other magnesium. The second kind is the traditional herbal registration, valerian and lavender among them, which the medicines regulator registers for the temporary relief of sleep disturbances on the basis of long traditional use rather than trial evidence, a status the registration's own wording states on the pack, and which is honest in its way: a buyer is told exactly what is and is not behind it. The third kind is the sleep formula, a blend of magnesium with 5-HTP, chamomile, lemon balm, a B vitamin and sometimes a herbal, often in a proprietary blend that states the total and not the parts, so that the one ingredient with authorised claims is present at an unknown dose and the rest are present at doses nobody can judge; the formula is the aisle's least reviewable product and usually its most expensive per day. Two counters, and a lifter who walks in asking for a sleep supplement is sent to whichever the shop decides, unless they know the difference and ask.

The pharmacist as the shelf's one asset, the four questions to ask at the counter, the aisle's magnesium read by the four reads, when it is a doctor's matter, and the verdict

What a pharmacy's sleep shelf has that no online listing can match is the pharmacist, a qualified person who is paid to answer questions about exactly this, and the review of the shelf is really the four questions a lifter asks before buying from either counter. Question one: is this for a few nights or a habit? The pharmacist's answer sorts the counters, because the licensed sleep aids are for the first and nothing on either counter is honestly for the second. Question two: what will it do tomorrow morning to a training session and a drive? The sedating antihistamines have a known answer, drowsiness and slowed reaction into the next day, and a lifter with a 6am session or a commute needs to hear it; the aisle's products have no next-day effect, which is both their safety and their limitation. Question three: what may the aisle's products lawfully say? A pharmacist knows the difference between a food supplement's authorised claims, a traditional herbal registration's wording and a medicine's licence, and will say which category a product is in if asked, which is the sorting a listing never does. Question four: when has a sleep complaint become a doctor's conversation? A pharmacist will route it: a complaint that has run for three nights a week for three months is chronic insomnia, for which the guidelines name cognitive behavioural therapy as first-line and which a doctor can arrange, and a complaint arriving with low mood, with snoring and pauses a partner has noticed, or with daytime sleepiness that makes driving unsafe is a referral rather than a purchase at either counter.

If the aisle's magnesium is what the lifter leaves with, it is read by the four reads that review any magnesium: the elemental dose and its NRV percentage, since an aisle label may give a compound weight; the form, with oxide common on a pharmacy shelf and glycinate or citrate better absorbed; pence per day at the labelled serving; and the testing, confirmed by a certificate for the batch if the chain's own brand will send one, which some will and some will not. The benchmark is the aisle's product with the word for sleep taken off it: {FL}, two capsules with the evening meal, 1500mg magnesium bisglycinate stated as 300mg elemental at 80% NRV, carrying the authorised claims for normal nervous system and psychological function and the reduction of tiredness and fatigue and no claim about sleep because none exists, batch tested for lead, mercury, arsenic and cadmium with the certificate on request, UK made under GMP and BRC, 180 capsules for £19.99 at 22p a day. The verdict for a lifter is a verdict on two counters: the pharmacy counter is worth it for three nights of a specific disruption, bought after the pharmacist's questions and stopped before the tolerance arrives, and not worth it as a habit; the aisle is worth it only for the one mineral read for what its label says, and not for the herbals registered on tradition or the formulas that hide their doses; and before either counter comes the sleep diary, two weeks of onset, waking and quality that tells a lifter which complaint they have, which is usually the afternoon caffeine, the evening session or the bedroom, and which neither counter sells a product for.

What to check on the label

Questions people also ask

Are Boots sleep supplements any good for lifters?

A high street pharmacy chain's sleep products are two counters rather than one shelf: the pharmacy counter sells sedating antihistamine sleep aids, licensed medicines for short-term use that work for three nights of a specific disruption and bring next-day drowsiness and a tolerance that arrives within days, and the supplement aisle sells magnesium with claims for normal nervous system and psychological function and no sleep claim, herbals registered on tradition rather than trials, and formulas with hidden doses; for a lifter the counter is worth it for a few nights, the aisle only for the one mineral read for its label, and the sleep diary comes before both.

What is the difference between a pharmacy sleep aid and a sleep supplement?

Legal category, which decides everything the product may say and do: a pharmacy sleep aid is a licensed medicine, a sedating antihistamine sold after a pharmacist's questions with an indication for short-term use, known next-day effects and a tolerance that develops within days; a sleep supplement is either a food supplement, which may carry only authorised nutrient claims and none about sleep, or a traditional herbal registration, which may be sold for temporary sleep disturbance on the basis of long use rather than proof of efficacy; a pharmacist will say which category a product is in if asked, which no listing does.

Can I take an over-the-counter sleep aid before a morning training session?

The pharmacist will advise against it for a reason specific to a lifter: sedating antihistamines produce drowsiness that lasts into the next morning, slow reaction time on the drive and drag a working set, and their licence is for short-term use because tolerance to the sedation arrives within days of nightly use; a lifter with a 6am session or a commute needs to hear the next-day answer before buying, and a lifter who sleeps badly in general needs the sleep diary and, if the pattern has run for months, a doctor's conversation rather than the counter.

What should I ask the pharmacist about sleep supplements?

Four questions: whether the product is for a few nights or a habit, which sorts the licensed sleep aids from everything else; what it will do tomorrow morning to a training session and a drive; what the aisle's products may lawfully say, since a pharmacist knows the difference between a food supplement's authorised claims, a traditional herbal registration's wording and a medicine's licence; and when a sleep complaint has become a doctor's conversation, which a pharmacist will route when the pattern has run for three nights a week for three months or arrives with low mood, snoring with pauses or unsafe daytime sleepiness.

Is pharmacy own-brand magnesium for sleep worth buying?

Only when read for what its label says rather than for the word for sleep on the front, which no magnesium may claim: the elemental dose and its NRV percentage, since an aisle label may give a compound weight, the form, with oxide common on pharmacy shelves and glycinate or citrate better absorbed, pence per day at the labelled serving, and whether the chain will send a certificate for the batch; a benchmark of a stated 300mg elemental glycinate at 80% NRV, batch tested for four metals at 22p a day, gives the reads something to land against.
