Ingredient science

Cross-referenced with PubMed & Examine.com

✓No flagged ingredients detected
Caffeine50mg
✓ Proven

Around 3mg per kg of body weight reliably improves endurance performance and focus; count all caffeine sources across the day.

Ashwagandha extract (KSM-66) (root) (Withania somnifera)300mg
~ Likely

An adaptogenic herb with good evidence for reducing stress and improving sleep at 300–600mg of standardized extract; lower doses are less studied.

Acetyl-L-Carnitine (as Acetyl-L-Carnitine Chloride)250mg
Disputed

Involved in fat metabolism; supplements haven't consistently improved endurance performance.

Ginkgo Phytosome (Ginkgo biloba extract (leaf) / Phospholipid complex from Sunflower)240mg
Disputed

Studied for memory and circulation; large trials in healthy adults have found little benefit.

PURENERGY (caffeine pterostilbene complex)116mg
✓ Proven

Around 3mg per kg of body weight reliably improves endurance performance and focus; count all caffeine sources across the day.

Pterostilbene66mg
Disputed

Plant compounds marketed for healthy aging; human evidence is limited and may blunt some training adaptations at high doses.

Bacopa extract (leaf) (Bacopa monnieri)100mg
~ Likely

Trials suggest modest improvements in memory after 8–12 weeks of daily use; it doesn't work as an immediate focus aid.

Lutein from Lutemax 2020 (Tagetes erecta)10mg
Disputed

A carotenoid plant pigment studied for eye (lutein) or heart (lycopene) health; evidence for athletes is limited.

Zeaxanthin Isomers from Lutemax 2020 (Tagetes erecta)2mg
Disputed

A carotenoid plant pigment studied for eye (lutein) or heart (lycopene) health; evidence for athletes is limited.
