How 167 mg at 30% Becomes About 50 mg 5-HTP in SLEEPWELL
See why 167 mg of Griffonia extract at 30% equals about 50 mg of contained 5-HTP.
This label guide separates total extract mass from its standardized marker. In the current 2-capsule SLEEPWELL serving, 167 mg × 30% = 50.1 mg, reasonably stated as about 50 mg of 5-HTP already contained within the extract. The arithmetic explains composition, not absorption or an individual result.
