A true-cinnamon extract included in the glucose-metabolism complex alongside berberine.
Ceylon cinnamon ("true cinnamon") is distinguished from the more common Cassia cinnamon by a much lower coumarin content, which matters for long-term daily use.
It's grouped with berberine in Phytomem One's metabolic complex, with research generally focused on blood-sugar-related markers rather than memory or cognition directly.
Its inclusion here reflects the formula's broader premise that stable glucose metabolism supports brain function, rather than a direct neuro-active mechanism of its own.
