So I brought cheaper no brand glutathione (like £16 quid for 120) and jarrows formula. I also had ph strips. And compared them. I hope this helps someone.
My cheaper off brand had an alkaline ph, no reaction with baking soda and very little change in ph once a proportionate amount of baking soda was added the ph just above 7. After using it in a rectal implant I had a bowel movement and felt very nauseous.
Whereas the jarrows formula was acidic when dissolved in water and when mixed with baking soda went from translucent white to clear after bubbling. The jarrows also has a distinct ripe smell from opening the bottle and when dissolved in water.
Anyone know where I can purchase authentic glutathione in bulk.
