Reviewers overwhelmingly had a great experience with this company. People regularly mention that the items are of great quality and successfully help alleviate various health issues like hot flashes and fatigue. Reviewers are particularly happy with how energetic they feel and appreciate the smooth delivery and easy ordering experience provided by the team. However, some customers also noted that the supplements are quite expensive and the small jar sizes mean they run out quickly. A few other people also felt that the products did not produce any noticeable changes or results even after taking them for multiple weeks.
Auto-generated from all reviews of this business. For reference only.I started taking Hormone Harmony on July 20, and about 10 days later I started experiencing unusually heavy bleeding. I had not experienced this before taking the supplement. I’m wondering if anyone else has had a similar experience with Hormone Harmony, particularly with maca or vitex. I’ve stopped taking it for now and will be checking with my doctor.
I feel so much more balanced when taking hormone harmony, I feel I don’t suffer with pms near as much. I did stop taking for a while but noticed the difference straight away, had to restock

I've been on the complete gut repair for almost 5 months now and have noticed zero difference. My diet is healthy and exactly the same but nothing has changed. It's ridiculously overpriced considering you only get 3 weeks worth out of one tub. Don't waste your money.
Hi Michael, Thank you for taking the time to share your honest feedback. We’re sorry to hear that Complete Gut Repair hasn’t delivered the results you were hoping for. Since our supplements are made with natural ingredients, they can take some time to build up in your system. Some customers notice changes within a few weeks, while for others, it can take a little longer. Our support team is always happy to provide guidance on how to take the supplement and help you get the most out of your routine. We’d also like to clarify that each tub contains 24 servings, which can last up to a month depending on how the product is incorporated into your routine. We have already issued a refund for one of your jars, which should be reflected in your account within 3 to 5 business days. We’ve also sent you a follow-up email with further information. If you still have any unopened jars, you’re welcome to reply directly to that email so we can guide you through the return process and arrange a refund for those jars in accordance with our guarantee terms. We hope this helps clarify the options available to you, and we appreciate you giving our supplement a try. Warm regards, Happy Mammoth
I am 47 yrs old and I have been taking the Hormone Harmony for 3 years. After a year the migraines I would get twice a month due to my hormones and lasted up to 3 days completely stopped!!

Hormone Harmony is the real deal for menopause symptoms, felt better within 12 hours of my first dose. Taking later in the day has improved sleep and night sweats, overall feeling more mellow and relaxed. Also helps curb sugar and carb cravings throughout the day. Was initially skeptical, but now a believer, highly recommend!

The belly reset powder is good at producing firm feces and the Hormone Harmony &Ultimate Weight support appear to have lessened the hot flushes. I'm a bit cautious & will wait till I've finished the 2nd lot I ordered to see if the flushes have really tapered off. Amazing if they have.
