L-Tyrosine
Cognitive support, stress reduction, mood enhancement, focus.. This product offers 500mg of L-Tyrosine. While this is an adequate starting dose, many studies use 1000mg or more for optimal effects. It's a good entry point but not a full clinical dose for most applications.
7.5/10
VERY GOODL-Tyrosine at 500mg is at the minimum effective dose but only 50% of the 1000mg optimal. For cognitive support under stress, most studies use 500-2000mg. The dose works but leaves results on the table. Clean formula with just the amino acid and capsule ingredients. Taking two capsules would hit optimal dosing.
