GenkiBoost's Benefits ZEN FOCUS MATRIX

Green Tea Extract
Green tea extract provides a clean, steady release of energy thanks to its natural blend of caffeine and L-theanine. Unlike harsh synthetic stimulants, its catechin profile promotes smoother alertness without spikes or crashes. This makes it ideal for sustained concentration, calm focus, and mental endurance throughout the day.
L-Theanine
L-theanine works synergistically with caffeine to smooth out overstimulation, creating a state of relaxed clarity rather than jittery energy. It increases alpha brain waves, promoting calm mental focus and improved attention. Together with caffeine, it delivers a balanced, centered boost ideal for deep work or creative flow.
Alpha-GPC
Alpha-GPC is a highly bioavailable choline source that boosts acetylcholine—the neurotransmitter responsible for learning, memory, and rapid information processing. It enhances mental performance, reaction time, and cognitive accuracy under demanding tasks. This makes it a cornerstone ingredient for quick thinking and high-level focus.
Phosphatidylserine
Phosphatidylserine supports the structural integrity of brain cell membranes, helping neurons communicate efficiently. It plays a vital role in memory formation, stress regulation, and cognitive resilience. Regular intake has been shown to improve mental recall, information retention, and overall cognitive sharpness.

ZEN FOCUS MATRIX (Cont.)

Taurine
Taurine helps sustain clear thinking by supporting neural signaling pathways and stabilizing electrolyte balance, especially during periods of stress or intense focus. It also assists in regulating neurotransmitter activity, promoting smoother cognitive performance. Its calming yet stabilizing effects make mental clarity easier to maintain throughout the day.
Lion's Mane
Lion’s Mane is renowned for its ability to support long-term brain health by stimulating nerve growth factor (NGF) production. This enhances neural regeneration, communication, and synaptic connectivity. Over time, it contributes to improved memory, mood stability, and sustained cognitive function.
Panax Ginseng
Panax Ginseng acts as a powerful adaptogen, helping the mind stay resilient under stress while supporting stable, centered focus. It improves mental stamina, alertness, and cognitive performance during fatigue or high-pressure situations. Its balancing effects promote calm yet energized productivity.

We choose to use Erythritol as our sweetener since we find that it has by far the BEST flavor while also containing 0 calories. However, since it is for the most part a 1:1 ratio of sweetener to sugar, it requires a lot of it to sweeten the drink. Requires you to mix VERY well.

Currently we do not but we'd like to expand eventually!
