This Performance Lab review looks at the four Performance Lab products most relevant to cognitive performance: Caffeine 2, Energy, Sleep, and Pre Lab Pro. For each one, we cover what’s in the formula, the exact doses, the price, and who it’s realistically for.
Our method: we reviewed the published labels, ingredient research, and publicly available information from the manufacturer. We have not run clinical tests, and user experiences mentioned anywhere online are anecdotal rather than proof that a product works.

What Is Performance Lab?
Performance Lab is a supplement brand from the same company behind Mind Lab Pro. Its range covers cognition, energy, sleep, sports performance, and general health. Many of its vitamins and minerals use NutriGenesis®, which the manufacturer describes as a cultured form designed to resemble nutrients found in food.
The strength that comes up in almost every Performance Lab review, including ours, is label transparency: every product lists exact doses rather than hiding them in proprietary blends. That makes it possible to judge each formula on its own merits.
Performance Lab Caffeine 2
Performance Lab Caffeine 2 (formerly sold as Performance Lab Stim) is a caffeine formula built around a small, adjustable dose. Each capsule contains:
| Ingredient | Per capsule |
|---|---|
| Natural caffeine | 50 mg |
| L-Theanine | 100 mg |
| L-Tyrosine | 250 mg |
| Vitamins B2, B6, B9 (folate), B12 | 500 mcg / 750 mcg / 170 mcg DFE / 2 mcg |
What stands out: 50 mg is roughly half a small cup of coffee, so you can scale up one capsule at a time instead of committing to a large fixed dose. Caffeine combined with L-Theanine has been studied for attention and alertness, although no formula can guarantee a crash-free experience for everyone.
Keep in mind: it’s still a stimulant. At $44 for 30 capsules it costs far more than plain caffeine pills, so you’re paying for the added ingredients and the convenience. For more context, see our guide to energy without the caffeine crash.
Performance Lab Energy
Performance Lab Energy takes a stimulant-free approach, using nutrients involved in how cells produce energy. Per 2-capsule serving:
| Ingredient | Per serving |
|---|---|
| Acetyl-L-Carnitine | 500 mg |
| R-Lipoic Acid | 100 mg |
| CoQ10 (MicroActive®) | 100 mg |
| BioPQQ® | 10 mg |
| Magnesium (malate) | 60 mg |
| BioPerine® black pepper extract | 2.5 mg |
What stands out: it contains no caffeine, which makes it an option for caffeine-sensitive people. Carnitine and CoQ10 play roles in cellular energy metabolism.
Keep in mind: evidence that these ingredients increase perceived daytime energy in healthy adults is limited, so the effect is likely subtler than caffeine. At $69, it’s the priciest product in this Performance Lab review.
Performance Lab Sleep
Performance Lab Sleep combines magnesium (100 mg), Montmorency tart cherry (500 mg), L-Tryptophan (200 mg), and lemon balm (200 mg) per 2-capsule serving, with no added melatonin beyond the small amount naturally present in tart cherry.
What stands out: a formula with every dose disclosed, at $44. Keep in mind: L-Tryptophan affects serotonin, so check with your doctor if you take antidepressants. Our full guide to nootropics for sleep compares it with other options.
Pre Lab Pro
Pre Lab Pro is Performance Lab’s pre-workout formula, sold through the Performance Lab store for $59. It’s aimed at training sessions rather than desk work, so it’s the least relevant product in this Performance Lab review for most knowledge workers.
Keep in mind: if you compete in a tested sport, check any pre-workout against your federation’s rules first. See our guide to nootropics for athletes for supplement safety tips.

- You avoid caffeine but want daytime support: Energy, with realistic expectations.
- Your main issue is winding down at night: Sleep.
- You train hard and want a pre-workout: Pre Lab Pro.

Why We’d Choose Performance Lab
For energy and sleep support, we’d look at Performance Lab first for three verifiable reasons: every dose is disclosed, stimulant-free options sit alongside a low-dose caffeine option, and every product has a 30-day guarantee. It isn’t the cheapest brand, and the finished formulas have limited direct research, but it’s the range we’d compare first.
