CuratedFit
CURATEDFIT SUMMARY
Passes because this is a genuinely single-ingredient formula, Cognizin brand Citicoline, with no other active ingredients and only standard, functional excipients alongside it. Cognizin is produced by Kyowa Hakko Bio via a fermentation process rather than chemical synthesis, which is treated as biologically sourced under the CuratedFit Standard. There is no proprietary blend, no synthetic sweetener or flavoring, and the dose is clearly disclosed.
WHAT IT IS
A vegetarian capsule providing 500 mg of Citicoline (CDP-Choline) per two-capsule serving, using the Cognizin branded form, a registered trademark of Kyowa Hakko Bio Co., Ltd. Citicoline is a compound the body uses in the production of phosphatidylcholine, a phospholipid important for cell membrane structure, and is also positioned as a precursor supporting acetylcholine synthesis, a neurotransmitter involved in cognitive signalling.
WHO IT IS FOR
Someone looking for a standalone Citicoline supplement using a well documented, branded form, rather than a proprietary cognitive blend combining multiple nootropic ingredients at undisclosed individual amounts.

Cognizin is a trademarked, branded form of Citicoline manufactured by Kyowa Hakko Bio, produced via a fermentation process. This is treated as biologically sourced under the CuratedFit Standard, consistent with how other fermentation-derived actives are evaluated elsewhere in this catalogue. Branded ingredients of this kind typically carry a level of standardization and supply chain accountability that a generic, unbranded citicoline ingredient may not.

TRANSPARENCY NOTE
This product resolves a sourcing gap noted elsewhere in the catalogue, where Citicoline (Cognizin) was not available through Chinese Herbs Direct at all. This Life Extension formulation is a clean, single-ingredient option using the same branded Cognizin form that had been the specific target during that earlier sourcing search.
The fermentation-based production method for Cognizin is a meaningful natural origin point. Unlike some cognitive ingredients that can be produced via direct chemical synthesis, Cognizin's fermentation process is treated as biologically sourced under the CuratedFit Standard, consistent with how other fermentation-derived actives (such as Vitamin K2 in other reviews) are evaluated.
Citicoline has a reasonably substantial body of published human research behind it, including studies in older adults examining cognitive outcomes, and some evidence at lower doses for mood support. The 500 mg dose here sits within commonly studied ranges. The remaining Info flags, independent lab verification, heavy metals testing, and country of manufacture, are standard transparency limitations rather than failures.

Not confirmed via any of the six specific certifications this review checks.
