I’m ordering Immunocal for my daughter who has fibromyalgia with severe chronic pain that has lasted decades. After 2 weeks of gradually increasing her daily intake of Immunocal from 1 tsp to 1 pkg per day, she has reduced her oxycodone and other pain meds by two thirds and is feeling much less pain. My understanding is that she doesn’t make enough glutathione on her own and the Immunical is giving her precursors that she needs to correct this deficiency. She is delighted with this result, as am I. Seeing this improvement is wonderful. My daughter discussed her great response with her pain doctor who is looking into Immunocal for his other fibromyalgia patients.
