Watch for...
If amino acids are not digested readily, they convert to toxins in the gut... where a couple of them become phenols. This conversion to toxin/phenolic compounds may contribute to the phenol sensitivity condition that some people see with increased protein digestion. It could be that by taking enzymes to digest the meats, the production of toxins and more phenolic compounds will be reduced because the amino acids will be absorbed much sooner by the gut before they are converted to toxins. However at the same time, because more amino acids are absorbed, the tryptophan level decreases and serotonin levels drop (because the tryptophan gets out-competed by the other amino acids).
