I've been using Hormone Harmony for 2 weeks now, and the biggest difference I notice is digestive. I am much more "regular" now, feel less bloated. My period also seemed less symptomatic this time, with less cramping and bloating. I haven't noticed any cravings shifts, weight loss, etc - but will be giving it more time.

I never write reviews….but it works!
I never write reviews. But happy mammoth kept popping up on Facebook and I was desperate to start losing weight and feeling better. Not only does this kill my cravings and help me stick to my diet but I’m sleeping better and my night sweats are gone! It’s been a miracle for me.

I purchased Ultimate weightloss and Hormone Harmony. I did not lose a single pound or inch and am very upset that it cost so much with not a single positive result. I also purchased Hormone Harmony. It helped my hip pain for about two weeks then stopped working. I never saw any reduction in bloating or reduction in puffiness in my face. I spent over $135 in products that did not work. I am so disheartened because I desperately needed relief.

Hormone Harmony
After 5 years of perimenopause struggles—sleepless nights, constant hot flashes, and low mood—I finally feel like myself again. I was skeptical, but after just two weeks with Hormone Harmony, I’m sleeping through the night, my hot flashes are gone, and my belly is visibly flatter. I finally have the energy and will to live fully again. Thank you, Hormone Harmony!

60-day money-back guarantee - order one jar and try it without worrying if it will work
This is a lie. They will only refund the product if it is unopened. How exactly are you supposed to try it without opening it?

Waste of money
Waste of money. Tried over last 7 weeks and noticed zero positive results. There also seems to be no way for me to leave a review on the website so I dont know how they're collecting all these supposedly positive reviews... between the poor results and ridiculous spamming of emails and hounding to trial, this all just was a waste of time and money. Dont be fooled.
