I have used this product and found it very beneficial to clear brain fog and ease fatigue, both symptoms of fibromyalgia. It also helps immensely with eliminating die off symptoms when treating candida alongside Threelac. I never reached the full dose as I obtained the necessary benefits at half the stated dose and there was no need for any further increase. As an added bonus it can be very helpful when applied topically as well, blemishes or cuts heal noticeably quicker.
