"Sage extract improves memory and focus, clinically validated"
Trials behind SageXtra are small, single-dose studies on two age groups, not long-term daily use data.
-
"500mg L-Tyrosine supports focus and alertness"
Human stress-performance studies on tyrosine typically use doses several times higher, around 7-10 grams.
Consumer advice
If you want to try it, take it on days you actually need an afternoon mental boost rather than daily — that's what the trial data actually supports. Don't expect it to build lasting cognitive improvement over weeks; it hasn't been tested that way. If budget matters, a standalone L-Tyrosine supplement (taken at a higher 2-7g dose, with a doctor's okay) plus a basic sage extract would cost much less and let you control doses independently. Skip it if you're pregnant, nursing, or on an MAOI antidepressant.
