Q1: What is the ratio of L-Theanine to D-Theanine?
We utilize a chiral-specific purification process to ensure the L-form assay is ≥ 99%, with the D-Theanine impurity kept at negligible levels, ensuring maximal biological activity.
Q2: Is it suitable for use in high-transparency beverages?
Yes, our L-Theanine crystalline powder is 100% water-soluble. It creates a clear, colorless solution with no sediment, even in carbonated or highly concentrated formulations.
Q3: How does L-Theanine work with caffeine?
L-Theanine has a synergistic effect with caffeine. It promotes relaxation and alpha-wave production which helps to eliminate the jitters and crashes often associated with caffeine consumption.
