Frequently Asked Questions

Q: Why do I sometimes not feel theanine working?

A: Theanine is most noticeable when taken during times of increased stress. If you are already somewhat relaxed, the effect is less noticeable.

Q: What’s that smell?

A: You may have noticed a difference in the powder’s smell. This is due to a different synthesis, specifically the extraction process. The particle size is also smaller than before, which results in more airborne powder, creating a stronger smell than the larger particle size format.

Q: Will L-Theanine help me get to bed?

A: L-Theanine promotes relaxation and may or many not impact getting to bed. We avoid the ‘s’ word (rhymes with ‘sheep’), not only for rigid listing requirements, but also because L-Theanine is not meant to help with the ‘s’ word and may have the opposite effect for some people.
