Overview
•Caffeine at 100-200 mg per serving is generally safe for healthy adults but may cause insomnia, increased heart rate, or anxiety in sensitive individuals.
•L-theanine is well-tolerated with no major safety concerns at 200 mg doses; it often mitigates caffeine's negative effects like elevated blood pressure.
•Combination appears safer than caffeine alone for anxiety-prone users per recent athletic studies.
•Avoid if pregnant, breastfeeding, or with caffeine sensitivity/cardiovascular conditions without medical advice.
•Do not exceed recommended servings to prevent caffeine-related side effects like restlessness.
