This product is best suited for professionals, students, or creatives tackling demanding projects or exams.

Ingredient Synergy: Why Citicoline and L-Theanine Work Best Together
Citicoline is a precursor to acetylcholine, a neurotransmitter essential for memory and learning. It boosts mental energy and supports brain cell membrane health. L-theanine, an amino acid found in green tea, promotes relaxation without drowsiness by increasing alpha brain waves. When combined, citicoline provides the fuel for focus, and L-theanine ensures you stay calm and composed. The ONNIT Alpha Brain Black Label Nootropic leverages this synergy, delivering a balanced experience that many standalone supplements cannot match.
Quality and Certification: What to Look For
Not all nootropic supplements are created equal. Look for products that have been independently verified for purity and potency. The ONNIT Alpha Brain Black Label Nootropic carries IGEN non-GMO verification, meaning its label claims have been assessed by a third party. This certification gives you confidence that you are getting exactly what is promised, without hidden fillers or contaminants.

Dosage and Formulation: Getting the Right Amount
Effective nootropic supplements use clinically relevant doses. Citicoline typically requires 250 to 500 mg per day, while L-theanine works well at 100 to 200 mg. The ONNIT Alpha Brain Black Label Nootropic uses a proprietary blend that provides these compounds in optimal ratios, along with low-dose caffeine for an extra alertness boost. Avoid products that hide dosages behind a proprietary blend label; transparency is key. Our guide to best memory supplements can help you compare formulations.
