The Cognitive Power Stack is a targeted nootropic trio—Alpha GPC, Tyrosine, and Acetyl L-Carnitine—designed to enhance mental clarity, focus, and energy metabolism. These ingredients work synergistically to support neurotransmitter production, improve brain cell communication, and reduce mental fatigue.

Alpha GPC provides bioavailable choline to support memory and cognition. Tyrosine helps maintain focus under stress by supporting dopamine and norepinephrine levels. Acetyl L-Carnitine fuels mitochondrial energy in the brain, supporting mood, memory, and long-term brain health. This stack is ideal for high-performance professionals, athletes, and anyone looking to stay sharp and focused.

Everything at a Glance

GMO Free Gluten Free

Alpha GPC:

  • Supports cognitive function
  • Builds focus and clarity
  • Supports memory and protects against cognitive decline
  • May help improve long-term brain health

Tyrosine:

  • Improves focus and motivation
  • Supports stress management

Acetyl L-Carnitine:

  • Helps improve memory, focus, and cognition
  • Boosts energy production
  • Can help improve mood
  • Alpha GPC acts as a precursor to acetylcholine, a neurotransmitter responsible for learning and memory. It enhances neuronal communication, promotes neural tissue health, and supports overall brain function by increasing acetylcholine levels. It has also been linked to increased neuroplasticity, which is crucial for maintaining a healthy brain.
  • Tyrosine is a precursor to important neurotransmitters that regulate brain function and mood. It supports the synthesis of dopamine, which is involved in motivation and reward pathways, as well as norepinephrine and adrenaline, which are essential for the body's stress response. It also ensures optimal neurotransmitter production, promoting cognitive performance and stress resilience.
  • Acetyl L-Carnitine is a potent antioxidant that crosses the blood-brain barrier to energize neurons and improve mitochondrial function. It supports cognitive function, memory retention, and mental stamina, helping to fight mental fatigue and keep you productive for longer.

    Acetyl L-Carnitine
    Rated 5 out of 5 stars
    5 stars

    We I’ve been taking Acetyl L-Carnitine consistently for close to a year now, and it has easily earned a permanent spot as a staple in my supplement stack. I noticed a subtle yet sustained boost in daily mental clarity and overall vitality shortly after adding it in, and it has been a reliable performer ever since. Whether used for support during morning routines, focus, or general metabolic wellness, it delivers clean results without any jitters or crashes. Highly recommend it to anyone looking to elevate their daily wellness regimen.

    Amazing

    I only started taking this about a week ago, but after 3 days I could tell a difference. I do take your Creatine and a different brand of collagen, but am trying your collagen next month. I will be 84 in November, and my health is my daytime job. I also do strength and balance classes twice a week, play golf, walk and do 12.3.30 3 times a week on the treadmill and add skiing in the winter🙋‍♀️ I feel great and love life!
