IV glutathione has been fantastic for me. The only side effect I had was that I was much more fatigued for a couple of weeks. That's gone and has not recurred. They tell us to take epsom salt baths the night of an IV to help with detox symptoms.
After just a couple of days after the first IV, my long-time sleep problem was much improved, and I'm so grateful for that. Also, my extreme sensitivities to supplements I need for mood, mitochondrial support, and energy have gotten so much better. Before glutathione, I could only take minute, non-therapeutic doses because any more would wreck my sleep. I've also been able to increase methyl donors.
You wouldn't mistake me for a normal, but I no longer stagger about like one of the undead. I wish I had known about this years ago, but my doctor just recently started offering it.
