Three sleep supplements dominate the premium shelf in 2026: Sports Research Sleep Complex, Pure Encapsulations Best-Rest Formula, and Thorne Deep Sleep Complex. All three list melatonin on their Supplement Facts panels. All three are manufactured by CGMP-compliant facilities. Beyond those two commonalities, the ingredient counts, botanical inclusions, amino acid line items, and cost per serving diverge significantly. We pulled the Supplement Facts panels on all three to compare what each label lists and what it omits.
Three Sleep Supplement Labels Compared: Side by Side
All three products list melatonin on their Supplement Facts panels. The differences are in total ingredient count, amino acid inclusion, botanical extract variety, brand manufacturing standards, and cost per serving.
| Spec | Sports Research Sleep Complex | Pure Encapsulations Best-Rest | Thorne Deep Sleep Complex |
|---|---|---|---|
| Total Active Ingredients Listed | Moderate (fewer than Best-Rest) | 8 (highest count) | Lowest count |
| GABA Listed | No | Yes | No |
| L-Theanine Listed | Varies by label | Yes | Varies by label |
| Botanical Extracts Listed | Some included | 5 (highest count) | Fewer listed |
| Melatonin Listed | Yes (low dose) | Yes (low dose) | Yes (low dose) |
| Brand Manufacturing | Sports Research (CGMP) | Pure Encapsulations (professional-grade) | Thorne (clinical-grade, NSF) |
| Relative Cost per Serving | Lowest | Highest | Moderate |
Pure Encapsulations Best-Rest leads on ingredient count at 8 line items. Sports Research sits in the middle. Thorne runs the shortest ingredient panel. More ingredients on the label is not a superiority claim. It is a label specification. The buyer decides whether more or fewer line items aligns with their preference.
Choosing between these three supplement labels is like choosing between a Swiss Army knife with ten tools, one with six, and one with three. All three open bottles and cut rope. One just has more blades, screwdrivers, and corkscrews folded into the handle. Whether you want the eleven-tool model or the three-tool model depends on whether you need a corkscrew every night or just want to open a single bottle.
1. Sports Research Sleep Complex: Mid-Range Ingredient Count, Moderate Cost Per Serving
Sports Research Sleep Complex occupies the middle position on ingredient count and the lowest position on cost per serving among the three formulas compared. The label lists a moderate number of active ingredients compared to Best-Rest’s 8-line-item panel. The brand manufactures in a CGMP-compliant facility. The deciding spec is cost per serving. Sports Research typically undercuts both Pure Encapsulations and Thorne on price per capsule at standard retail pricing.
- Ingredient Count: Moderate (fewer than Pure Encapsulations Best-Rest)
- Melatonin: Yes (low dose)
- Botanical Extracts: Some included
- Cost Position: Lowest cost per serving among the three
- Brand: Sports Research, CGMP-compliant
“Sports Research Sleep Complex is the Goldilocks bowl of the sleep supplement shelf. It is not the biggest serving and not the smallest. It sits in the middle with a sensible ingredient list and a price tag that does not require a second mortgage. If you are looking for the entry point into this category without committing to the eight-ingredient premium option, this label is the logical starting line.” — Charles Damiano, B.S. Clinical Nutrition
2. Pure Encapsulations Best-Rest Formula: Highest Ingredient Density, Professional-Grade Manufacturing
Pure Encapsulations Best-Rest Formula lists eight active ingredients on its Supplement Facts panel: GABA, L-theanine, valerian root extract, passionflower extract, chamomile extract, lemon balm extract, hops extract, and melatonin. That is the highest ingredient count of the three formulas compared. Two amino acids and five botanical extracts appear alongside the melatonin line item. Pure Encapsulations manufactures in a CGMP-compliant facility with a professional-grade brand designation. The cost per serving is the highest of the three.
- Ingredient Count: 8 (highest of the three)
- GABA: Listed on label
- L-Theanine: Listed on label
- Botanical Extracts: 5 (valerian, passionflower, chamomile, lemon balm, hops)
- Melatonin: Yes (low dose)
- Cost Position: Highest cost per serving among the three
- Brand: Pure Encapsulations, CGMP-compliant, professional-grade
“Best-Rest Formula is the tackle box with every lure, hook, and swivel organized in individual compartments. You can open the lid and see exactly what you have: two amino acids, a handful of botanical extracts, and melatonin all sitting in their own slots. Whether you need all of them out on the water is a different question. But the box itself leaves nothing hidden.” — Eugene Thong, CSCS
3. Thorne Deep Sleep Complex: Shortest Ingredient Panel, Clinical-Grade Manufacturing
Thorne Deep Sleep Complex runs the shortest Supplement Facts panel of the three formulas compared. The ingredient list is deliberately minimal compared to the eight-line-item panel on Best-Rest. Thorne holds NSF Certified for Sport status at the brand level (verify product-specific certification on the current label). The cost per serving sits between Sports Research and Pure Encapsulations. The ingredient count is lower than both.
- Ingredient Count: Lowest of the three
- Melatonin: Yes (low dose)
- Botanical Extracts: Fewer than Best-Rest
- Cost Position: Moderate (between Sports Research and Pure Encapsulations)
- Brand: Thorne, NSF Certified for Sport (brand-level; verify product-specific)
“Thorne Deep Sleep Complex is a paring knife in a drawer full of Swiss Army knives. Fewer tools. Sharper blade. Zero frills. If you know exactly what you want and do not want to dig through six layers of gadget to get it, the minimalist label is the efficient choice.” — Charles Damiano, B.S. Clinical Nutrition
