Cognium Complete

Phosphatidylserine is the real star here for memory support. The silk protein is novel but under-researched. Huperzine A is potent but needs cycling. Decent formula, but calling it 'Complete' is generous.

6.5/10
GOOD

Interesting ingredient selection with some clinical backing. Phosphatidylserine is legit. Silk protein is novel but thin on evidence.

Whenmorning

Cognitive benefits are most useful during the day.

Foodwith food

Phosphatidylserine is fat-soluble and absorbs better with dietary fat.

SafetySome cautions

Huperzine A inhibits acetylcholinesterase. Don't combine with cholinergic drugs or other nootropics affecting acetylcholine.

ResearchLimited evidence

PS is well-studied. CERA-Q has limited independent research.

What We Like

  • Phosphatidylserine at 100mg is a clinically-studied dose.
  • Huperzine A boosts acetylcholine (the memory neurotransmitter).
  • Uses branded ingredients (CERA-Q, Sharp-PS) with quality control.

Watch Out For

  • Silk protein hydrolysate (CERA-Q) has limited independent research.
  • Huperzine A needs cycling and can cause side effects.
  • Only 4 ingredients feels incomplete for a 'Complete' product.
