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.

Hi there,

Thank you for taking the time to share your experience with us. We’re truly sorry to hear that the supplements didn’t deliver the results you were hoping for—and we completely understand how disappointing that must feel, especially when you were seeking relief and support.

While many of our customers have seen positive changes, we know that every body is different, and results can vary depending on individual health circumstances, lifestyle factors, and how long the product is used.

We’d love to look into your order and do everything we can to help. Could you please reach out to us at reviews@happymammoth.co with your order number and full name? Please use the subject line “Review: Requested Details” so we can support you accordingly.

We also want to reassure you that your order may be eligible under our 60-day money-back guarantee. And if you have unopened jars remaining, we can help arrange a return for those as well.

Hi Tony,

Thank you for your feedback, and we’re truly sorry to hear that the supplement didn’t meet your expectations and that you had difficulty getting in touch with us.

We understand how frustrating that must have been, and we sincerely apologize if your emails were missed—this is certainly not the experience we aim to provide. We’ve recently experienced a high volume of inquiries, but we are actively working to improve our response times and ensure no messages go unanswered.

Regarding our 60-day money-back guarantee, it's important to clarify that we do honor this for one opened jar per supplement, even if purchased as part of a multi-jar order. If you ordered more than one jar and have unopened units, we can also arrange a return and refund for those as long as they are within the return window and in proper conditions.

Please reach out to us directly at reviews@happymammoth.co with your order number and full name, and include the subject line "Review: Requested Details" so we can resolve this for you promptly.

Your satisfaction is very important to us, and we’d love to turn this experience around for you.

Warm regards,
Happy Mammoth

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

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?

Hi there,

Thank you for your feedback, and we’re truly sorry for any confusion or frustration caused regarding our 60-day money-back guarantee.

We’d like to clarify that our guarantee absolutely does allow you to try one jar, even if opened, and request a full refund if you're not satisfied with the results. You do not need to return an unopened jar to qualify for the refund. Its different if you buy 3 units for example or if you have purchased a bundle.

If you were previously informed otherwise, we sincerely apologize. It may have been a misunderstanding or a miscommunication, and we’d love the opportunity to make this right for you.

Please email us at reviews@happymammoth.co with your order number and the name on the account, using the subject line “Review: Requested Details”, and our team will promptly review your case and issue a refund if eligible.

Your satisfaction is our top priority, and we’re here to help.

Warm regards,
Happy Mammoth

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.

Hi Phoebe,

Thank you for taking the time to share your feedback—we’re truly sorry to hear about your experience and the disappointment you've felt. We completely understand how frustrating it can be when expectations aren't met, and we genuinely appreciate you bringing this to our attention.

Our supplements are made with 100% natural ingredients, and while many customers do see positive results within the first few weeks, everyone’s body responds differently based on individual health, lifestyle, and internal imbalances. That said, we never want you to feel unsupported or unheard.

Regarding the review system, we understand your concern. We collect verified reviews through independent third-party platforms (like Trustpilot), as well as direct customer submissions via email after a purchase. We include all honest feedback—positive or negative—because it helps us grow and improve.


We were able to locate your account and issue the corresponding refund under our guarantee, with the information provided. This will be reflected in the following 3 to 5 business days.

We’re also sorry to hear you felt overwhelmed by our emails. You can unsubscribe at any time using the link at the bottom of any message—we’ll make sure you’re not contacted further if you prefer.

Your satisfaction matters deeply to us, and we’d really thankful for the opportunity to turn this around for you.

Warm regards,
Happy Mammoth.
