SleepWell vs Solgar 5-HTP Complex: A Label Comparison
TL;DR:
- This compares two exact market blends, using declared quantities rather than product names or ingredient-count claims.
- Differences in ingredient selection do not establish differences in sleep benefit.
- The shared B6 entry and complete warnings need the same attention on both sides. Ingredient studies do not rank these finished formulas.
SleepWell France and Solgar Griffonia 5-HTP Complex UK are both multi-ingredient supplements. The useful buying question is how their complete formulas differ, not which product name sounds more focused on sleep.
This comparison uses a two-capsule SleepWell serving and the UK manufacturer's per-capsule table. Those are different denominators, not equivalent doses or interchangeable instructions. More 5-HTP, more magnesium or more ingredients cannot settle an efficacy comparison without evidence on the finished products.

|---|---|
| Which version? | SleepWell France and Solgar UK, with their exact labels |
| Which serving? | Two capsules versus one capsule; not equivalent doses |
| Which ingredients? | Review every entry in each complete mixture |
| Which evidence? | The reviewed studies do not rank these finished formulas |
| What remains open? | Complete warnings and the conflicting UK directions |
Identify the Exact Versions
The SleepWell side is the France regulatory label reviewed on 2 October 2026. It declares quantities per recommended daily serving and gives two capsules in the evening or morning. That means an alternative time, not two capsules at each time. Its 90-capsule container holds 45 of those servings; pack arithmetic does not establish an appropriate duration of use.
The comparator is the official UK Griffonia 5-HTP Complex listing. Its one/day summary conflicts with the one-to-two-capsule description. The table stays per capsule; confirm directions from the complete pack label.
Market identity matters because a familiar brand name is not a complete specification. Keep the exact product, market and label date attached to a comparison. Retailer summaries and older illustrations should not silently replace the pack being considered.
Compare Declared Quantities
| Entry | SleepWell France: two capsules | Solgar UK: one capsule |
|---|---|---|
| Griffonia / 5-HTP | 167 mg aqueous seed extract at 30%; about 50 mg contained 5-HTP | 334 mg seed extract at 30%; 100 mg contained 5-HTP |
| L-tryptophan | 500 mg | Not listed |
| Magnesium | 160 mg, bisglycinate | 56.3 mg, oxide/bisglycinate |
| Valerian | Not listed | 100 mg root extract |
| Vitamin B6 | 10 mg, pyridoxal-5'-phosphate (P-5-P) | 10 mg, pyridoxine hydrochloride/P-5-P |
| Zinc | 10 mg, citrate | Not listed |
| Folate | 400 µg, calcium (6S)-5-methyltetrahydrofolate | Not listed |
| Vitamin D3 | 5 µg in the nutrient table; source unresolved | Not listed |
| Black pepper | 4 mg fruit extract at 95% piperine | Not listed |
“Not listed” describes the reviewed declarations; it is not an assay result. The contained 5-HTP is already part of the Griffonia extract, so extract mass and contained marker must not be added together as separate actives. For SleepWell, 167 mg multiplied by 30% gives 50.1 mg, appropriately rounded to about 50 mg. This describes the label, not absorption or response.
Source forms add information but do not provide an automatic absorption ranking for the complete blends. The mineral amounts are the declared nutrient amounts, not the weights of the entire source compounds. Keeping units and denominators visible prevents an attractive number from answering the wrong question.
Consider the Whole Formula
A person comparing the same amount of contained 5-HTP across labels is asking a different question from someone looking for the additional entries in SleepWell. Neither question requires treating one option as better for everyone.
The UK option may fit a preference for a higher 5-HTP amount or avoiding SleepWell's additional entries. A shopper looking specifically for those entries may prefer the latter. These are formula preferences, not efficacy findings or personal advice.
A reason to include one ingredient does not automatically justify the rest of a fixed formula. Conversely, an ingredient you do not want does not become irrelevant because the front label emphasizes another one. Changing the number of capsules changes the mixture, not one selected row independently.
Apply that test evenly: identify what is wanted, what is unnecessary and what remains unclear. If the question concerns one ingredient alone, both blends still require a whole-formula review. There is no need to add a supplement simply to complete a comparison.
Read the Clinical Evidence Boundaries
Sutanto and colleagues' 2024 randomized trial studied 100 mg 5-HTP daily for 12 weeks in older adults in Singapore; 30 participants completed it. Investigators were blinded, but the control group did not receive a placebo. The authors reported improvements in certain sleep measures, with differences according to baseline sleep quality.
That is a small study in a defined population, not a universal sleep claim. It used another manufacturer's 5-HTP capsules, not either finished blend here. Matching a declared ingredient amount does not also match the participants, formulation, comparator or outcome.
Shell and colleagues' 2010 placebo-controlled trial included 18 people, nine in each group. It tested Gabadone, an amino-acid preparation containing GABA and 5-HTP, and used questionnaires for sleep outcomes. Its reported differences belong to that tested preparation.
A combination trial cannot isolate the effect of one ingredient without an appropriate comparison arm. It also cannot be transferred to a mixture with different ingredients merely because both contain 5-HTP. These studies offer context for reading a claim, but they do not provide a head-to-head comparison of SleepWell and the selected UK product.
Keep Vitamin B6 in the Total-Intake Check
The two table quantities each supply 10 mg B6. This shared entry deserves the same attention regardless of which formula has more rows. The check includes food, fortified foods and other supplements, not just the candidate bottle.
EFSA's 2023 vitamin B6 opinion sets an adult tolerable upper intake level of 12 mg per day for total intake, covering all B6 vitamers. P-5-P is not exempt. The opinion uses peripheral neuropathy as the adverse effect behind the upper-level assessment; it is a safety reference, not a recommended target.
Two UK capsules would supply 20 mg B6 by multiplication. That arithmetic is not an instruction to take them. It illustrates why an unresolved serving statement cannot be dismissed when reading the complete formula. This guide does not set an alternative dose or approve a combination.
Subtracting one supplement's B6 from the upper level would not calculate a personal allowance for another product. The rest of the diet, other sources and individual circumstances still matter. Record the actual routine for professional review instead of using the limit as a capsule budget.
Compare Warnings and Open Questions
SleepWell's France label is for adults, advises against use during pregnancy or breastfeeding, and calls for a doctor's consultation with antidepressant use or neurological disorders. Do not exceed its daily dose. Keep it away from young children; supplements do not replace a varied, balanced diet and healthy lifestyle. Store it cool and dry, protected from light and moisture.
The fresh UK web source does not reproduce a complete pack caution panel. That is a gap in this comparison, not evidence of fewer restrictions. Obtain the complete label rather than substituting warnings from a different market. Until then, the warning review cannot be considered complete on both sides.
SleepWell's nutrient table lists D3, but its ingredient list does not identify that vitamin's source. That detail remains unconfirmed. The UK page describes vegan, soya-free, dairy-free and gluten-free suitability; no independent finished-product test certificate was verified here for either product. SleepWell's reviewed label does not establish allergen-free status.
Suitability wording and an independent test report answer different questions. An omitted declaration also stays unconfirmed rather than becoming a negative or positive claim. For an allergy or source restriction, obtain clarification tied to the actual market version and pack.
Before Deciding
Keep a comparison sheet separate from an actual-use record. The first shows alternatives; the second lists what is already taken, at what amount and frequency. Putting both candidates into the second list would turn research into a combined routine without reviewing it.
Bring the full labels and medicine list to any needed professional discussion. Clarify the reason for considering a product, repeated nutrient entries and unresolved wording. Do not remove a professionally advised product because a shopping alternative shares an ingredient, or change prescribed medication based on a supplement comparison.
Deferring a purchase until a serving or ingredient question is answered is a valid outcome. Where composition already answers the shopping question, record that distinction without converting it into a claim about treatment, sleep quality or superiority.
Current Product Information
The SleepWell France product page is an information link, not a purchase recommendation. Its reviewed variant was unavailable on 2 October 2026. No matched purchase-cost check was performed across both markets, so this guide does not rank price, subscription value or cost per day. Check current information alongside the complete pack label; neither price nor availability resolves the formula questions above.
Frequently Asked Questions
Which formula is better for sleep?
The reviewed evidence does not establish a winner between these finished products. Compare the whole formula against the reason for considering a supplement, then resolve warnings and unclear label details. A larger amount, more actives or a familiar brand is not a substitute for product-specific clinical evidence.
Does 167 mg of Griffonia mean 167 mg of 5-HTP?
No. The SleepWell France label gives 167 mg extract standardized to 30% 5-HTP. Multiplying those values gives 50.1 mg, reasonably stated as about 50 mg already contained in the extract. It is label arithmetic, not an independent assay, absorption measurement or expected benefit.
Can I take both products to get the ingredients from each?
This comparison does not approve their combined use. Bring complete labels, food and fortified-food intake, other supplements and medicines to a professional review. Do not turn a shopping shortlist into a daily schedule or use an upper intake level as an allowance for another capsule.
Does P-5-P remove vitamin B6 from the safety check?
No. The EFSA upper level used here covers all B6 vitamers and total intake. A source-form name does not exempt its declared amount from that check. The reference also does not establish the suitability of the whole mixture for an individual.
Should SleepWell be taken in both the morning and evening?
No such combined schedule follows from the reviewed France label. It specifies two capsules in the evening or morning, not two at each time. Follow the complete label for the pack you have, do not exceed its recommended daily dose, and resolve any conflicting information before use.
