    Improved sleep over tryptophan alone.
  

*by K***K on Reviewed in the United States on April 20, 2021*

The niacinamide and B6 added to the tryptophan made a big difference in the hours slept vs the plain tryptophan. Bestvite uses acorbyl palmitate and silica for filler and manufacturing. I try to avoid magnesium stearate in supplements.Thank you Bestvite.
