A study was just published that showed NAC(N-Acetyl-Cysteine) was helpful in lessening the damage done by antibiotics in lyme patients.
It lessened the Oxidative stress that occurs from either antibiotics or from some natural herbs.
I felt this was important because oxidative stress is believed to be part of the herx response that occurs when antibiotics are destroying the lyme bacteria.
I also want to note, that I personally take NAC and I feels it helps with my energy level. I ran out of it once and could really tell that I felt worse. My doctor recommended 600mg. twice a day.
Oh, also when I started Artemisia my doctor said you need to careful and take some supplements to help this oxidative stress. He suggested Zyflamend .
Hope this helps! Have a good day!
