The ingredient
What is L-Theanine?
L-theanine is an amino acid found in tea. Researchers have studied it on its own as well as in combinations. Those combinations are not interchangeable with a single-ingredient supplement.

Evidence, with its limits
What does the research say?
A small trial in healthy adults explored stress-related symptoms and cognitive function. It was short, used a specific preparation, and included researchers employed by the ingredient supplier. It does not prove that an OfRoot formula will deliver the same results, or treat anxiety.

How to read a L-Theanine label
Look for the named ingredient, its amount per serving, and any added caffeine or other active ingredients. Our final formula and serving details will be shared before sale.
Before adding it
A conversation
comes first.
This is ingredient education, not a suggestion that you should take it.
- Check with a clinician or pharmacist if you take medicines or other supplements. Do not assume that an ingredient found in tea is suitable for everyone.
- Discuss use during pregnancy or breastfeeding with a qualified healthcare professional. We are not proposing a children's product.
- Ongoing anxiety or sleep difficulties deserve professional support. A supplement is not a substitute for that care.
