Overview
•L-Theanine at 200mg and caffeine at 100mg are within safe daily limits for healthy adults, with GRAS status for L-Theanine up to 250mg per serving.
•Potential mild side effects from caffeine include jitteriness or insomnia in sensitive individuals, but L-Theanine mitigates these in this 2:1 ratio.
•Contains tree nut allergen (coconut from MCT oil), posing risk for those with coconut allergies; avoid if sensitive.
