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.

I actually really like the product but I'm shattered to realise that I subscribed to a bottle that originally had 96 tablets in it and now my bottles only contain 72 and I'm still paying the same price? That has put a bad taste in my mouth in terms of my trust of this company 😔
Reply from Happy Mammoth 2026-07-06
Hi there,
Thank you for taking the time to share your feedback. We truly appreciate your honesty.
We're sorry to hear about your concerns. We completely understand why this change would leave you feeling disappointed.
The product was updated from 96 capsules to 72 capsules because the daily serving was also adjusted from 4 capsules to 3. As a result, each jar still provides a 24-day supply. Since many customers take the supplement Monday through Friday and take a break on weekends, one jar can last up to 30 days.
We'd love the opportunity to review your subscription and answer any questions you may have. As reviews are not linked to customer accounts, please feel free to reach out to us at [email protected], and we'll be happy to look into it for you.
Thank you again for your feedback.
Warm regards,

I decided to try Happy Hormone and Happy Hormone Plus+ combo. The main reasons for trying these supplements were to help with menopause acne and joint stiffness. Yes, those symptoms improved in a slow a steady way. My intuition says that I will need a solid 3 months worth of supplements for these symptoms to go away or reduce substantially.
What I wasn't focusing on (not my primary goals), but the quickest and most obvious result, was the disappearance of puffiness and the weight loss!
I'm genuinely so surprised by this. I am much more interested in my holistic health and wellbeing, so the speedy weight loss is really quite unexpected. I have lost at least 1 clothes size in this first month of taking the product.
In summary, I would definitely recommend this duo. May your journey to wellness with this product be as successful as mine 🙏🏻

I had read all the 5 star reviews and wanted to see if Happy Hormone really worked that well. After 4 bottles I feel less agitated, less bloated, more calm. The day to day jobs are less triggering and I feel happier.

I’m using the metabolic balance…and it’s given me back control.
I’m using the metabolic balance product. I take 3 a day. I am at the same time, being more active and thoughtful about food, but I’m not on a ‘diet’ or running every day! Or at all. But, I feel better. I feel I can eat more mindfully. Hunger is less, I eat less. I don’t really understand it, but I feel mentally stronger, and in turn, it has made me feel better and more in control, physically.
I’m 68 and I’ve been taking it for about 31 days. It was about 2 weeks ago when I really noticed, and though I don’t weigh myself, a jacket that was too tight to zip up, now fits.

I love the complete gut repair it works wonders. Mixed with my morning green smoothie goes down a treat and I feel it has helped my regularity. i think the only downside is the size of the pot does not last a full month and it cost.
