Life Extension Citicoline (CDP-Choline), 60 Vegetarian Capsules (250 mg per Capsule)

Life Extension's Citicoline (CDP-Choline) is a nootropic supplement designed to support memory health, focus, and attention. It provides Cognizin® Citicoline, a patented form of citicoline that serves as a precursor to the neurotransmitter acetylcholine, which is involved in brain cell communication and energy production.

This formula uses Cognizin®, a registered trademark of Kyowa Hakko Bio, which has been studied in clinical research. For example, one randomized, double-blind, placebo-controlled trial involving 100 healthy adults aged 50-85 found that 500 mg of citicoline daily for 12 weeks supported improvements in episodic and composite memory. Another study noted that 250 mg taken over four weeks was associated with fewer recall errors in healthy adult women. The product is offered in vegetarian capsules, with a serving size of two capsules delivering the clinically referenced 500 mg dose, and it is gluten-free and non-GMO.
