Sirona Nutrition L-Theanine 90C

Calm Focus. Clear Mind. Natural Calm.

L-Theanine is a naturally occurring amino acid found primarily in green tea leaves. Renowned for its ability to promote a state of relaxed alertness, L-Theanine is one of the most popular and well-researched supplements for stress relief, mental clarity, and sleep support — without causing drowsiness.

Key Benefits

• Promotes Calm Without Sedation — L-Theanine uniquely induces a relaxed, focused state by increasing alpha brain wave activity, helping you feel calm and centered without feeling sleepy or foggy.
• Enhances Focus & Mental Clarity — Often paired with caffeine, L-Theanine smooths out the jittery edge of stimulants while amplifying concentration, attention, and cognitive performance.
• Reduces Stress & Anxiety — Clinical studies show L-Theanine helps lower cortisol levels and reduce the physiological and psychological effects of everyday stress.
• Supports Restful Sleep — By calming an overactive mind, L-Theanine can help you fall asleep more easily and improve overall sleep quality — without next-day grogginess.
• Boosts Mood — L-Theanine supports the production of serotonin, dopamine, and GABA — neurotransmitters that regulate mood, motivation, and emotional balance.
• Antioxidant Properties — As a component of green tea, L-Theanine contributes to antioxidant activity that helps protect cells from oxidative stress.

Who It's For

Whether you're navigating a demanding workday, winding down after a stressful evening, or looking for a natural edge in focus and productivity, L-Theanine is a gentle yet effective daily supplement for anyone seeking balance between calm and clarity.
