If you're after cellular energy and mitochondrial support, this delivers **PQQ** at 10mg per capsule — right at the floor of the 10–20mg range used in human studies. The label's once-or-twice-daily directions matter here: one capsule puts you at the studied minimum, while two gets you to 20mg, the dose most trials actually used.
PQQ is mechanistically interesting — it's thought to help your body build new mitochondria, the cellular components that produce energy. But the human evidence is still preliminary: a handful of small, short trials on fatigue, sleep, and cognition, the largest with just 17 people and no large RCTs yet. Treat the energy and focus claims as emerging, not established.
PQQ is often paired with CoQ10, since the two target mitochondria from different angles. On its own at this dose, you're getting a reasonable entry point into an ingredient that's promising but not yet proven.
