In my opinion no one should take considerable amounts of the nutrients involved in the livers phase 1 detoxification without taking the sulfur containing amino acids involved in the livers phase 2 detoxification. Everyone should know about how the liver detoxifies. For, if you stimulate phase 1 while disregarding phase 2 detoxification then it can potentially have a very detrimental effect on both your physical and mental health. L-Cysteine is one of the amino acids which are important for phase 2 detox. Also remember phase 3 detoxification. Please check out Christopher Shade (PhD) before you start detoxing. Blubonnet L-Cysteine is natural (see Ajipure)

This l-cysteine seems to be a high quality product. Comes in a glass jar to retain freshness better than plastic. I take it to regrow hair, and have seen some very positive results over the last 3 months.
