Performance Lab Energy

What it does

Performance Lab Energy is a caffeine-free capsule sold through performancelab.com. The vendor calls it a 'caffeine-free workout and daily energy supplement' for 'cellular energy, cardio performance, muscle strength, and clean focus'. One serving is 2 vegan pullulan capsules holding 500mg acetyl-L-carnitine (from acetyl-L-carnitine HCl), 100mg microencapsulated BioEnhanced R-lipoic acid, 100mg MicroActive Q10 (coenzyme Q10), 10mg BioPQQ (pyrroloquinoline quinone), 60mg magnesium as magnesium malate (14% of the US Daily Value) and 2.5mg BioPerine black pepper extract (95% piperine), which the vendor adds 'for enhanced absorption'; a bottle holds 30 servings. The label suggests 2 capsules in the morning or early afternoon on an empty stomach. The vendor states it is 'third-party tested for purity and potency' but names no lab. We found no entry for it on the Australian Register of Therapeutic Goods (ARTG): searches for 'Performance Lab' on 2026-10-05 and again on 2026-10-06 returned no results, and the product page shows no AUST number, so it reaches Australian buyers as an imported food supplement rather than a listed medicine.

How it works

Energy is built around mitochondria, the parts of cells that turn food into usable energy. Acetyl-L-carnitine carries fatty acids into mitochondria and donates acetyl groups for making acetylcholine; its positive cognitive trials used 1.5-3g a day in older adults with mild cognitive impairment, mild dementia or pre-frailty (Montgomery 2003 meta-analysis; Passeri 1990; Malaguarnera 2022), at least three times the 500mg here, and we found no trial in healthy young adults. PQQ improved some memory and attention scores in three small 12-week trials at about 20mg a day (Itoh 2016, Shiojima 2021, Tamakoshi 2023), two of them with authors affiliated with the PQQ manufacturer; Energy has 10mg. The vendor describes CoQ10 and R-lipoic acid as mitochondrial cofactors and antioxidants, but we found no positive cognitive trial of either: 300mg CoQ10 a day did not improve attention or working memory over 6 months in a trial in schizophrenia (Maguire 2021), and 100mg alpha-lipoic acid a day did not improve cognition in the only dose-matched trial we found, also in schizophrenia (De Lima 2023). BioPerine is there to aid absorption; we have not verified whether 2.5mg of piperine changes how well these ingredients are absorbed. Energy itself has not been tested in a published trial.

What to expect

Performance Lab says Energy starts working in around 30 minutes and that you may notice 'increased vitality', more motivation, a brighter mood and better muscle strength and cardio performance during exercise. It contains no caffeine or other stimulant. The positive cognitive trials of acetyl-L-carnitine and PQQ ran for 12 weeks or longer at 2 to 6 times these doses, so any cognitive effect at Energy's doses is uncertain. The label suggests 2 capsules in the morning or early afternoon on an empty stomach; the product page also suggests 2 capsules 30-45 minutes before a workout. Orders to Australia ship from the brand's Australian depot in 3-6 working days or from its UK depot in 7-14 working days, depending on destination (per performancelab.com's shipping page, checked 2026-10-05). We saw only US-dollar prices ($69 one-time) when we checked.
