Theses supplements are truly working!
These supplements are helpful and made my mood better and lighter. I also lost some weight although it took a couple of months and then it stopped again. But I feel good and found my favorites among all their products witch are many well put together supplements. I have a monthly subscription and it works just fine, you can change it whenever you want or skip a month without a problem. Their emails are many and easy to understand and they are always available if you need to contact them.

Hi Michelle
Thank you for sharing your experience with us. We are sorry to hear this product was not a good fit for you.
It’s good to hear that you initially felt a difference, though we understand your concern with the changes you experienced afterward. Based on what you described, it was the right call to discontinue the product, as you may be sensitive or intolerant to one of the ingredients.
In situations like this, it can be helpful to consult with a healthcare professional who can guide you in identifying any specific sensitivities and advise on what may work best for you moving forward.
We’ve gone ahead and issued a full refund for your order, and you can expect the funds to be processed within the next 2 to 5 business days. We’ve also sent you a follow up email to check in and gather a bit more information, as well as to see if there’s anything else we can assist you with.

Bought hormone harmony
Bought hormone harmony - didn’t do a single thing for me. Within the 60 day “money back guarantee” I requested a refund and they do not process a full refund. Buyer beware for a product that doesn’t work and false advertising for the refund

Hi there,
Thank you for sharing your experience with us. We’re sorry to hear this has been your experience, especially given the progress you’ve made previously.
While some people may notice temporary digestive changes at the beginning, symptoms like constipation and increased discomfort can also indicate that the product isn’t the right fit for you. You may consider pausing use and, if needed, checking in with your healthcare professional.
We’d really like to support you further. Please feel free to reach out to us at reviews@happymammoth.co with your order details so we can take a closer look and assist you directly. And if you decide not to continue, please remember our 60 day money back guarantee is there for you.

TRUTHFUL & AMAZING PRODUCT !!!!
I researched many products for hormonal changes in woman after 50 and the cortisol effect. I decided on Hormone Harmony and I am sooo glad that I did. It has helped with the stubborn weight loss after trying every diet and exercise routine on the planet. Hormone Harmony has also helped with the bloating effect in my face and belly. I have seen the changes in about 2 months as well as friends and family. I just want to thank Hormone Harmony for being truthful and honest with what their product can deliver to woman over 50 .

Only gives you 1 hour to modify an order and then won’t help amend.
I tried the Hormone Harmony but they didn’t work for me so cancelled the subscription.
Something has gone wrong and my subscription hasn’t been cancelled. I received an email to say that my order has been processed and I have 1 hour to make any changes! I was on a flight when the email came through and so I missed the opportunity to cancel my order. I have tried the chat function, they couldn’t help and said I would be passed to an advisor within around 15 minutes. It’s now been an hour and I am still no closer to being able to cancel the order. Giving customers 1 hour to change an order is unacceptable.
