Reviewers are particularly happy with how energetic they feel and appreciate the smooth delivery and easy ordering experience provided by the team.

When I first started taking Hormone Harmony it made me burp throughout the day so I took two instead of three. That helped. Within three or four weeks I was sleeping better. And after a few months a few pounds came off. At about a year, I felt like I’d hit a plateau so I added the third capsule. That jump started the effects again, lost some more weight and felt more balanced mood-wise. At some point I wondered how I’d do without it and went off of it for a couple weeks. And my stress level went up and I thought it was stressful events at work. I went to a regular acupuncture appointment and was describing how I felt to my acupuncturist and he said, “Frankly, that sounds hormonal to me!” So I started taking Hormone Harmony again and once again felt more balanced and able to handle stressful situations better. I’ve recommended it to many women.

The happy hormone tablets have helped my system to calm down, reduced bloating and generally helped with peri-menopause symptoms. While it isn't a 'cure all' it is certainly a big step in the right direction.
You must take it consistently every day, I certainly notice if I have forgotten for a couple of days - cravings come back and my system just doesn't feel settled.

So far I have used one bottle of tablets and my mind has felt clearer, less fog. I like having a sharper mind, less mood swings and I have noticed that I feel happier. I am laughing again, unfortunately no weight loss. But so far so good.

I finally found a solution! I thought about going on HRT for my hot flashes, mood swings, and low libido, but I decided to try Hormone Harmony first. Though it didn't happen immediately, I started to eventually notice big improvements. Now, I've added Hormone Harmony Plus to my daily routine, and everything is better - improved libido, less mood swings, and almost NO hot flashes! I'm so grateful for Happy Mammoth!

60 day full refund guarantee is misleading and not 100% true
The product did not work for me which I acknowledge can happen it’s not the same for everyone but due to the 60 day money guarantee I felt safe trying, however this was not true . I feel the 60 day money back guarantee policy that is put on the home and ordering page is extremely confusing and misleading. I reached out after just over 30 days to request a refund as I was seeing no results after buying a bundle and they told me their policy only will refund one bottle, you’re stuck with the rest of the amount you paid for the bundle (which are highly encouraged and recommended to see results due to needing to take for more that 30 days and 1 bottle only covers 24 days). This is only explained in very small detail somewhere other than the home and ordering page where it says “ Happy Mammoth’s Guarantee. We also have a "Down-To-The-Last-Scoop” 100% Risk-Free, 60-Day-Money-Back Guarantee for all of our products. We trust in the quality of the products we are offering and that they will help you regain your health, so we are offering a 60-day guarantee from the date of your purchase. If you don’t perceive any benefits after taking our supplements, reach out to us and our customer service team will process a full refund.” I hope the product will work for you however Just FYI will not get a full refund if it doesn’t. You will only get refunded for one bottle.

All their products and service are great. I have been taking Hormone Harmony for ages now and if for whatever reason I miss some, I really notice the difference. I can’t quite put my finger on what the difference is but, to nick an old ad line, they make me feel like me but on a really really good day!
