It takes about 2 months of taking these supplements consistently and then you will feel so much more like yourself! I also have seen the food noises go almost all the way away.

Try it!!
My pre-menopause anger was annoying me! I couldn't stand myself. It was like PMS on steroids. Now on month 4 of Hormone Harmony my mood is stable, I'm more patient and down 10pounds!

I love the probiotic protein powder. The weight loss protocol is okay - I’ve seen limited results so far, but am giving it more time.

Happy Mammoth has changed my life!!
Happy Mammoth has changed my life!!! I honestly feel the way I used to! Maybe even better! For months, I struggled so bad with weight gain, brain fog, fatigue, joint pain, and the worse irritability. I kept reading the reviews about how great it was so I finally gave in purchased it. By day three, I was from under that dark cloud that I lived with almost every day. Today makes two weeks and all I can say is, I’m back baby!! I won’t stop taking this, ever. I tell everyone I know, that needs to know, about it. This product is a complete game changer and an answer to my prayers.

Hormone Harmony…Results
I started taking the Hormone Harmony the day I received it (April 9, 2026). I was having bad post menopausal symptoms. I already notice that I'm calmer, and I lost 12 pounds that wouldn't budge before. I will reorder when it's time! So good to start seeing results! Linda B. Indiana

Terrible customer service
Terrible customer service. I requested to cancel the whole order and the customer service person kept going back and forth asking the name and delaying intentionally I guess so the order was shipped and I sent it back and now they won’t pay shipment. I’m just so annoyed that I won’t order anymore from them. Don’t recommend.

Hi Mila,
Thank you for taking the time to share your experience. We understand how frustrating this situation must have been, especially with the back and forth communication.
We’ve reviewed your case and can see that your initial interaction was with our virtual assistant. At that stage, it wasn’t fully clear whether you wanted to cancel the order for Hormone Harmony or the one for Hormone Harmony PLUS+, which led to some delays while clarification was being requested. We understand how that may have felt, and we’re sorry for the inconvenience caused by the repeated questions.
Once your case was escalated, a member of our team advised rejecting the delivery so it could be returned without additional steps.
We will now follow up with you via email to confirm whether you were able to refuse the delivery successfully. If not, we’ll provide you with a return label so you can send the product back free of charge.
We appreciate your feedback and the opportunity to make this right.
Warm regards,
Happy Mammoth

Back on it and Feeling Great
I’ve been using Happy Mammoth for a few years and originally thought it wasn’t doing much because I still felt hot at night. I stopped and tried patches from my doctor, but I ended up with every symptom — nausea, mood swings, sensitivity, and the night heat didn’t improve.
That’s when it clicked that Happy Mammoth was helping me more than I realised. I went back on it last month, renewed my subscription, and I’m feeling good again. For me, it’s been genuinely effective.
