The score explained
evidence, testing and value, weighed before price
Why 7.2 of 10: Provisional: research-branded ingredient, same modest evidence as the category.
what’s good
- Suntheanine is the form used in most trials
- 90 capsules, good value
- Vegan capsule
worth knowing
- Slightly lower dose per capsule
- Same subtle-effect caveat as all theanine
what the evidence says
Same evidence picture as L-theanine generally: small human trials support relaxation and a calmer wind-down, with more limited direct evidence on sleep measures. The Suntheanine branded ingredient is the form used in much of that research, which is a small point in its favour when choosing between otherwise similar products.
Plain-language assessment of the human evidence. No cherry-picked citations.
