Has been life-changing for me. It has significantly improved my mental health, not just during the intense phases of PMDD before my period. But I actually feel much better during the rest of my cycle, too.
Jasmin
I really love this company. It is weird to say I feel seen and cared for by them. I just don't think I have felt like this with any other business.

Then in the third month, my PMS symptoms were reduced by 80%! I still have menstrual pain, but the intensity has decreased again a bit.
Moko
I'm four cycles in... and will never look back. The changes were gradual and cumulative, but by the third cycle I felt as though my life had completely changed, I haven't had to take a day off work due to PMDD symptoms since the second cycle of using Nettle.
