A high-quality, effective Suntheanine L-Theanine supplement from a trusted brand, providing a strong 200mg dose.

Analysis

The use of Suntheanine ensures a high-quality, pure form of L-Theanine, which is crucial for maximizing its effectiveness. The 200mg dosage aligns with numerous studies demonstrating significant benefits for relaxation without sedation, improved focus, and a positive impact on mood. While the product name indicates 100mg, the ingredient list clearly states 200mg per serving, confirming its potent dose. Online reviews and nutritionist recommendations often favor patented forms like Suntheanine for their reliability.

Pros
  • Contains 200mg of Suntheanine, a premium, patented form of L-Theanine known for superior purity and efficacy.
  • Optimal dosage for effective stress relief, mental focus, and mood support.
  • Natural Factors is a reputable brand with a focus on quality and research.
  • Large quantity of 120 servings provides good long-term value.
Cons
  • Product name '100 mg' is inconsistent with the '200mg' ingredient quantity, which may cause confusion for consumers.
  • Price per serving is slightly higher than some generic L-Theanine options, though justified by the Suntheanine quality.
Warnings
  • No significant warnings specific to L-Theanine when taken at recommended doses.
