A doctor recommended it for a relative in 2018, but it was only available at that time from a compounding pharmacy. He tried it for a while, but it didn't help him. I don't remember how much he was taking, but they recommend 1,200mg per day. I also don't know if his problem was nerve pain. It apparently has anti-inflammatory benefits as well, another reason I'd like to try it. I can no longer take any OTC NSAIDs like ibuprofen or Aleve, even a small dose, as it gives me gastritis.
