What the Experts Say

“Stress affects so many areas of your life, from sleep to sports performance to energy levels. It’s clear your mental health drives your physical health. Suntheanine® helps you settle into a more positive cycle: sleeping better at night leads to more daytime energy which leads to more quality sleep and continued productive days.”
Suntheanine® replaces my 2 p.m. cup of coffee, giving me the power of coffee without the jitters. A calm, focused and alert attention is the type of energy we all desire: energy that makes us more efficient, not frazzled and distracted.”
