Performance Lab Sleep review summary
This review examines the older Performance Lab Sleep formula recorded in our archive. Its specific focus is the archived sea-buckthorn formula versus the verified lemon-balm version. The historical label and analysis below are not a claim that every current bottle has this composition, and this review does not infer that the product has been discontinued.
Current manufacturer check
The manufacturer’s Supplement Facts checked on 10 November 2026 lists, per two capsules: magnesium 100 mg (bisglycinate, taurate and NutriGenesis), tart cherry concentrate 500 mg, L-tryptophan 200 mg and lemon balm extract 200 mg. The older sea-buckthorn entry below belongs to the archive. The difference is material: neither the former serving analysis nor a past anecdote verifies this version’s clinical effect. Manufacturer promises of no grogginess and rapid results remain claims, not conclusions of this review.
Formula analysis: The archived sea-buckthorn formula versus the verified lemon-balm version
The archived Performance Lab Sleep table listed magnesium 100 mg, CherryPURE tart cherry 500 mg, TryptoPure tryptophan 250 mg and sea buckthorn 100 mg. The manufacturer’s current page instead lists a lemon-balm-containing formula, so the older four-ingredient record must not be presented as the current label.
The historical magnesium amount refers to the declared nutrient amount, not the total weight of every magnesium compound. The tart-cherry 50:1 ratio describes concentration, not an exact melatonin dose. A fruit source cannot be assumed to deliver a known or clinically effective melatonin exposure without measurement.
Tryptophan is a precursor in serotonin/melatonin pathways, but that does not establish faster sleep onset or better next-day energy from the finished product. The old first-person sleep account and categorical claim that the supplement works were not documented clinical testing and are not retained as proof.
Archived ingredient table
The following is the original article’s historical transcription. Serving amounts, percentages, spelling and ingredient descriptions may reflect an older label or transcription errors. It is retained for formula comparison, not as current-use instructions. Historical Daily Values are not recalculated here.
Performance Lab Sleep Ingredients | |
| Ingredients | Amount Per Serving |
| Magnesium (as Magnesium Bisglycinate and NutriGenesis® Magnesium*) | 100 mg (25% DV) |
| Montmorency Tart Cherry (as CherryPURE®) (Prunus cerasus) (fruit) (50:1 concentrated ratio) | 500 mg |
| L-Tryptophan (as TryptoPure®) | 250 mg |
| Organic Sea Buckthorn (Hippophae rhamnoides) – fruit | 100 mg |
Safety and suitability
Magnesium can interact with absorption of some medicines, and tryptophan makes a review of serotonergic medications relevant for the archived version. Sleep products can also affect alertness; natural sourcing is not a guarantee against next-day effects. Persistent insomnia warrants assessment.
What the evidence does not establish
Ingredient studies, manufacturer descriptions and customer reviews cannot demonstrate the effect of this complete formula. We have not established a controlled clinical trial of this exact archived formulation in this review. No hands-on testing, clinical credentials or laboratory verification by Nootropic Geek are claimed.
Verdict on the recorded formula
This page preserves the older formula’s distinctive label questions while separating it from current product claims. It does not establish a reliable sleep or recovery benefit, and it should not be used to choose a current serving without checking the current package.
Historical prices, stock statements and refund or subscription terms have been removed because they are not verified current offers. Before comparing value, establish the exact current formula, serving size and total purchase terms.
