Mental Calmness delivers clinically-proven stress relief that actually works without making you drowsy. Suntheanine L-Theanine reduces anxiety and restores mental calm while keeping your mind sharp and focused. The chewable format works faster than capsules when stress hits.
Why It Works
CLINICALLY TESTED: Suntheanine is the only L-Theanine backed by published research — not generic amino acids from unknown sources.
BRAIN WAVE SUPPORT: Increases alpha brain waves for that calm-but-alert state, plus boosts mood-supporting neurotransmitters dopamine and serotonin.
CAFFEINE BALANCE: Reduces negative effects of caffeine including jitters and over-stimulation while maintaining mental clarity.
What's Inside
Clean chewable formula with tropical fruit flavour and organic cane sugar. Each tablet delivers 100mg of pure Suntheanine L-Theanine. Made in Canada by Natural Factors.
Why we carry it: Natural Factors exclusively uses Suntheanine — the patented form with actual clinical research, not cheap generic L-Theanine.
This is my go to for stress and calm, mental clarity.

Bought for my son. Easy to take, and taste good. He seems to be more steady these days. Great supplement for easing anxiety.

Mental Calmness chewable tablets
Excellent product. Was recommended by our naturopathic doctor for my daughter who struggles with generalized anxiety. She suggested that she could take some in her purse or in her backpack or in the car and chew one whenever she found herself getting anxious. Now I use them too to help relax before bedtime.

Settles the racing thoughts in the night
I’ve used Mental Calm for years and find it helpful when I waken in the night and can’t get back to sleep. Doesn’t put you to sleep but settles you down and calms the overthinking.
