Frequently Asked Questions
What is the difference between Alpha-GPC and citicoline?
Both are high-quality choline sources. Alpha-GPC converts more directly to acetylcholine and is preferred for acute cognitive enhancement and athletic performance. Citicoline also provides cytidine (which converts to uridine, supporting brain phospholipid synthesis) and may be better for long-term neuroprotection. Choose based on your goals — you don't need both.
