Buying Guide
Dosage and Potency
L-theanine supplements range from 50 mg to 400 mg per serving. The right dosage depends on your sensitivity and goals. For subtle daytime calm, 100 to 200 mg often works well. If you need stronger support for stress or sleep, higher doses like 400 mg may be appropriate. Always start low and adjust based on your response.
Some products, like the L-Theanine 400 mg from NUTRAHARMONY, offer a single high-potency capsule for convenience. Others, such as Integrative Therapeutics L-Theanine, provide a flexible two-capsule dose. Consider your lifestyle and whether you prefer a once-daily or split dose.
Form and Convenience
L-theanine comes in capsules, softgels, gummies, and liquid drops. Capsules and softgels are portable and precise.
