What Is Alpha-GPC Powder?
Alpha-GPC, a natural choline source found in the brain, also known as alpha-glycerylphosphorylcholine and choline alfoscerate. Alpha-GPC is one of if not the most efficient choline source supplement with superior bioavailability. Recent studies suggest that the supplementation of Alpha-GPC may improve athletic performance, primarily in power output during exercise[1]


Alpha-GPC Benefits & Uses May Include: 

  • Supports Enhanced Cognitive Function†
  • Supports Enhanced Memory Recall†
  • Supports Improved Power Output†

How Does Alpha-GPC Powder Work?
Alpha-GPC is a chemical released when the fatty acid of soy and plants breaks down. Alpha-GPC, a biosynthetic precursor of acetylcholine neurotransmitters, crosses the blood-brain barrier more readily. Alpha-GPC is regarded as one of the best sources of Choline as a nootropic, and it functions by increasing the amount of available Choline in the body. This Choline then naturally converts to and influences the production of acetylcholine. Acetylcholine is a powerful neurotransmitter, which releases from nerve cells or neurons, that is responsible for learning, memory, and other critical functions both relating to cognition and the endocrine system. Not only is this chemical accountable for learning and memory, but it also plays a significant role in REM sleep, or Rapid Eye Movement, the movement of muscles, and the signaling of pain. Acetylcholine operates as an activator and an inhibitor in the nervous system as well as the central nervous system. Subsequently, in the central nervous system, it prevents the activating of the chlorogenic system. Furthermore, acetylcholine also operates in the peripheral nervous system, wherein it allows for the contraction of the skeletal muscles.

    Best Deal Anywhere! Seriously!!

    Posted by Matt Cline on 15th Sep 2017

    The product mixes well in water and has noticeable effects affirming its authenticity. I believe my memory retention improves as a result, and my sleep quality undoubtedly does improve. Try it for yourself! If you find Alpha GPC for a lesser price than Hard Rhino, there is a reasonable chance it is fake. I know from experience, so you should stick with companies who have their products lab tested.

    Great value

    Posted by Christian on 10th Nov 2015

    Hard Rhino's Alpha GPC 50% is the highest quality Choline source that I have came across. I have noticed that my memory, ability to think critically, and creativity has increased. It is also worth noting that I stack this product with fish oil and piracetam. Overall, this is a great quality product, and I recommend to anyone who is interested in enhancing their overall cognition.
