Somnapure Review (2026): Cheap, Fully Labelled, and Worth It?
Quick answer: Somnapure is an inexpensive tablet sleep aid sold by Force Factor. Its two-tablet serving lists 3mg melatonin, 500mg valerian, 300mg lemon balm, 200mg L-theanine, 120mg hops, and 50mg each of chamomile and passionflower, and every amount is on the label. The L-theanine is at a dose used in research and the melatonin will do most of the noticeable work; the valerian and the smaller herbal doses have weak evidence behind them. At the time of writing Walmart listed 30 servings for $17.36, which is under 60 cents a night. That makes it one of the better-value multi-ingredient sleep formulas, and we would rather say that plainly than pretend otherwise. The main reasons to skip it are 3mg melatonin leaving you groggy, valerian not agreeing with you, or wanting a longer money-back guarantee.
Somnapure has been on pharmacy shelves for well over a decade, and “Somnapure review” still gets searched every day. Most of the results are thin affiliate pages that repeat the box copy. This page reads the label against the research, gives you the real price, and says honestly where it beats the product we recommend, because in a few ways it does. We have not tested this product ourselves; what follows is based on the manufacturer’s published label and the sources linked in the text.
What Somnapure is, and who makes it
Somnapure is currently sold by Force Factor, a Boston-based supplement company best known for sports and men’s health products. Force Factor’s BBB profile is accredited with an A+ grade. The brand is older than its current owner: it was marketed around 2011 by a company called Peak Life, LLC, when the advertising industry’s watchdog reviewed its ads (more on that below).
The version on sale today is a drug-free dietary supplement tablet. One naming trap is worth knowing about. There was once a Somnapure Clinical Strength product, listed on the NIH’s DailyMed database in 2015, that was a completely different thing: an over-the-counter drug containing 50mg diphenhydramine, the antihistamine in many “PM” products. If you come across an older bottle or listing, check which one it is. This review covers the melatonin-and-herbs tablets.
The full formula, with doses
From the Supplement Facts on Force Factor’s Somnapure product page. The serving is 2 tablets, with 30 servings in a 60-tablet bottle, taken 30 to 60 minutes before bed.
| Ingredient | Per 2 tablets | Evidence at this dose |
|---|---|---|
| Melatonin | 3mg | Strong for a modest effect; more than many need |
| L-Theanine | 200mg | Moderate; matches trial dose |
| Valerian extract (root) | 500mg | Weak / inconclusive |
| Lemon balm extract (leaf) | 300mg | Weak |
| Hops extract | 120mg | Weak |
| Chamomile extract | 50mg | Weak at this dose |
| Passionflower extract | 50mg | Weak |
| Calcium (as dicalcium phosphate) | 92mg | Not marketed as a sleep ingredient |
Credit where it is due: there is no proprietary blend here. Every active has a stated amount, which is more than many sleep products manage, including some that cost several times as much.
Ingredient by ingredient: what the research supports
Melatonin, 3mg: strong evidence, still more than many people need
A 2013 meta-analysis in PLoS One found melatonin shortens the time it takes to fall asleep and slightly increases total sleep. The NIH’s NCCIH describes the benefit as modest. At 3mg, Somnapure is more restrained than the 5 to 10mg tablets that dominate pharmacy shelves, but it is still several times the 0.5 to 1mg range that many people do fine on. If you wake groggy, the melatonin is the likeliest reason. We go through the dose question in YU Sleep vs melatonin.
L-Theanine, 200mg: the best-dosed ingredient on the label
L-theanine, the calming amino acid in tea, is usually studied at around 200mg a day. In a 2019 randomised controlled trial in Nutrients, healthy adults taking 200mg daily for four weeks reported improvements in stress-related symptoms and sleep measures compared with placebo. It calms you without sedating you, which suits the racing-mind kind of insomnia. Somnapure gives you the full research dose.
Valerian, 500mg: popular, inconclusive
Valerian is the backbone of the herbal part of the formula, and it is the weakest link. The NIH Office of Dietary Supplements’ valerian fact sheet describes the evidence for insomnia as “inconclusive”, and a 2006 meta-analysis found possible improvement in sleep quality alongside evidence of publication bias. The 500mg dose is in the range used in trials, so if valerian works for you, this is a fair test of it. It can add to the effect of alcohol or sedatives.
Lemon balm, 300mg: weak
Lemon balm’s sleep evidence comes mostly from small studies. One often-cited example is a 2011 open-label pilot in people with mild-to-moderate anxiety and sleep disturbances, which had no placebo group. It is a plausible calming herb, but the evidence is not strong.
Hops, 120mg: weak
Hops has mostly been studied in combination with valerian rather than on its own, with mixed results (the ODS fact sheet linked above covers several of these combination trials). Here it plays a supporting role.
Chamomile and passionflower, 50mg each: weak
A 2019 meta-analysis found chamomile improved sleep quality but did not show a benefit for insomnia itself. The main passionflower sleep trial was a small 2011 study using passionflower tea. At 50mg each, we would not count on either doing much.
Our read on the formula: Somnapure is really two useful ingredients, 3mg melatonin and 200mg L-theanine, plus a full dose of a herb with inconclusive evidence and a few small herbal extras. That is a fairly honest product. It will not transform chronic insomnia, and nothing in a supplement aisle will. But it does what a budget melatonin-plus-calm formula should, and it tells you exactly what is in it.
Price and guarantee, at the time of writing
Force Factor’s product page did not display a price when we checked, and Somnapure is mainly sold through retailers. Walmart’s Somnapure listing showed:
- 30 tablets (15 servings): $13.99
- 60 tablets (30 servings): $17.36, which works out to about 58 cents a night
Retail prices move often and differ between stores, so treat those as a snapshot. On the guarantee, we could not find a published money-back guarantee for Somnapure on Force Factor’s product page. If you buy at a retailer, that retailer’s return policy is what applies, so check it before you open the bottle.
Complaints, lawsuits and red flags
A 2024 labelling class action (allegations only)
In 2024 a proposed class action, Mendez v. Force Factor, LLC (Case No. 5:24-cv-02236), was filed in federal court in the Central District of California. According to a summary of the complaint, it covers 14 Force Factor products, including Somnapure 3mg melatonin and several other Somnapure versions. It alleges that front labels feature a dosage amount that you only reach by taking more than one tablet or capsule. On the Somnapure tablets we looked at, the Supplement Facts panel does state that the serving is two tablets. These are allegations, and we could not confirm the current status of the case from public sources.
An advertising watchdog review (2011)
In 2011 the National Advertising Division, the industry’s self-regulatory body, reviewed Somnapure’s advertising under its previous owner. It found a reasonable basis for many of the ingredient claims, but asked for two changes: make clear that the benefits come from regular use rather than a single dose, and label some sponsored “health news” content clearly as advertising. The company agreed to comply.
The complaint record
Force Factor’s BBB profile listed 7 complaints in the last three years at the time of writing, about short-filled bottles, odour, one adverse reaction, customer service and counterfeit sellers. None of the complaints shown mentioned Somnapure specifically. We found no FDA warning letter for Somnapure. Older complaint-board posts exist, but they date from the previous owner and did not tell us anything reliable about the product sold today, so we have not repeated them.
Who it suits, and who should skip it
Good fit if you…
- Want a cheap, fully labelled melatonin-plus-calm formula
- Have found that 3mg melatonin suits you
- Have a racing mind at bedtime (the L-theanine)
- Want to avoid serotonin precursors such as 5-HTP or tryptophan
Skip it if you…
- Wake groggy on 3mg melatonin
- Have had a bad reaction to valerian, or drink alcohol at night
- Take sedatives or other sleep medication
- Are pregnant or breastfeeding (ask your doctor)
- Want a manufacturer money-back guarantee
Safety notes. Melatonin can cause next-day drowsiness, headache, dizziness and nausea, and it can interact with some medicines (see the NCCIH page linked above). Valerian may add to the effect of alcohol and sedative drugs. Somnapure contains no serotonin precursor, which is one point in its favour for people on antidepressants, but anyone on prescription medication should still check with their pharmacist. Do not drive after taking it. If poor sleep has gone on for more than a few weeks, or you snore loudly or stop breathing at night, see a doctor rather than trying more supplements.
What we’d look at instead, and when we wouldn’t
We recommend YU Sleep first on this site (we explain why in why we recommend it first), so here is the honest comparison. YU Sleep is a liquid taken under the tongue. Its formula is red tart cherry, 5-HTP, vitamins B6 and B2, magnesium glycinate, apigenin, lemon balm, L-theanine, GABA and melatonin at 0.9mg, with no valerian, hops or passionflower.
Where Somnapure wins, and we will not pretend otherwise:
- Price. Somnapure costs well under a dollar a night. YU Sleep has no single bottle. At the time of writing it is $138 for two months, $177 for three, or $294 for six, which is roughly $2 a night on the three-month pack.
- Transparency. Somnapure publishes every dose. YU Sleep only discloses its melatonin dose, so you cannot check its L-theanine against Somnapure’s research-level 200mg.
- Antidepressant users. YU Sleep contains 5-HTP and Somnapure does not. If you take an SSRI or similar, Somnapure, or plain melatonin, is the more sensible thing to discuss with your doctor.
Where YU Sleep is the fairer pick:
- You wake groggy on 3mg. YU Sleep’s 0.9mg melatonin is closer to what the body makes, and grogginess is strongly tied to dose.
- Valerian does not suit you. YU Sleep has no valerian or hops.
- You want a guarantee. YU Sleep has a 60-day money-back guarantee. We could not find one for Somnapure.
- You want a broader formula. Apigenin, GABA, magnesium glycinate and tart cherry are extras Somnapure does not have, although, as we say in does YU Sleep work, their evidence ranges from moderate to weak.
Our honest steer: if you have never tried a combination sleep aid, Somnapure is a cheap way to find out whether melatonin plus L-theanine helps you. If you have, and the grogginess or the valerian put you off, that is when YU Sleep’s three-month pack is worth considering.
Groggy on 3mg, or valerian not for you?
YU Sleep: 0.9mg melatonin, no valerian, sublingual liquid, 60-day money-back guarantee. $138 for two months, $177 for three, $294 for six. The pricing block is about two-thirds of the way down a long sales page.

Frequently asked questions
Does Somnapure work?
For many people it will help them fall asleep a bit faster, mainly because of the 3mg of melatonin, with the 200mg of L-theanine helping with a racing mind. The herbal ingredients, especially valerian, have weak or inconclusive evidence. It is not a treatment for chronic insomnia.
How much melatonin is in Somnapure?
3mg per two-tablet serving, according to the Supplement Facts on Force Factor’s site. Each tablet therefore contains half that. Check the label of the version you buy, because other Somnapure products have used different amounts.
Is Somnapure safe to take every night?
Its ingredients are generally well tolerated in short-term studies, but long-term nightly use of any sleep aid is best discussed with a doctor, especially if you take other medication, drink alcohol or are pregnant or breastfeeding. Stop if you get next-day drowsiness or headaches.
Can I take Somnapure with antidepressants?
Somnapure contains no 5-HTP or tryptophan, so it avoids the main serotonin-syndrome concern that applies to products such as YU Sleep. Melatonin and valerian can still interact with some medicines, so ask your pharmacist or prescriber before combining them.
Is Somnapure better than YU Sleep?
On price and label transparency, yes. YU Sleep is the better fit if you wake groggy on 3mg of melatonin, want to avoid valerian, or want a 60-day money-back guarantee. It is not suitable for anyone on serotonergic medication because of its 5-HTP.
