Huge let down
Huge let down, so many positive reviews, not possible to give 0 stars. Tried two products, neither made any difference to hormone or gut health. Didnt work for me and money guarantee is not forthcoming

It worked for me!!
I have been using hormone hormony, mood switch and magnesium breakthrough for the past 4 weeks and I would say I am 95% better than what I was. I have more energy, I'm sleeping better and my family say I am more approachable. My mood swings have eased considerably! I look forward to seeing how I am in the next 4 weeks!

Do not bother
I am on my third bottle of hormone harmony , I have had no change at all.
I am still having hot flushes and night sweats. Lost no weight. Sleep pattern is still the same . I am also nauseous after taking. Also getting headaches. I am out of pocket by £150 and no better off. Very disappointed

Hi Kelly,

We completely understand your frustration.
We’re also sorry to hear about the nausea and headaches you’ve experienced.

Great experience and a product that truly works!!
Fast, efficient service with no hassle. The Prebiotic Collagen Protein is one of the best supplements on the market today. It is one of the very few that actually does what it says it will and fast!! I wish I could have found it years ago, because it has improved my quality of life and I will always take it from this point forward. It has transformed my waistline and did it incredibly fast and it has reshaped my digestive system in a fantastic way! My stomach used to be bloated out all of the time. It was huge. After one dose it was gone!!! Completely as God is my witness!! I have abs again at 57 years old

Happy for sure
Every person is different but Hormone Harmony has worked wonders for me! I have felt so much better during the day and a couple extra hours of sleep at night. I was so happy with that and gave added Weight Control and Cellulite Control. In 2 months, I have lost 6 pounds (slow but steady) and my husband has noticed the difference of my cellulite reduction. Try it! This might be your winning combination, too.

Metabolic Harmony very expensive
I have used this product for at least 6 months now and I am honestly not sure whether there has been any benefit. The subscription has been costing me £51.73 including delivery a month which isn’t cheap. It certainly hasn’t had a negative effect except the price and the only thing I will say is that the subscription is easy to manage so cancelling wasn’t a problem however I was offered a discount to stay. If they offered the discount at the start I probably wouldn’t have cancelled in the first place.

We’d love to take a closer look at your journey and see how we can better support you. If you’re open to it, please reach out to us at reviews@happymammoth.co with your details, and our team will be happy to assist further. There may also be an opportunity to explore a subscription setup that better suits your needs.
Thank you again for your feedback, it helps us continue improving.

Recommended the Prebiotic collagen…
Recommended the Prebiotic collagen shake by a friend. Purchased the salted caramel flavour. Yummmmmy! Whilst the scales haven’t changed, I feel like I’ve lost centimeters and am far less bloated.

Hi there,
Thank you so much for your feedback. We’re really glad to hear you’re enjoying it, especially mixed with coffee, that’s a great way to include it in your routine.
Just a quick tip: for best results, we recommend mixing it with cold or warm beverages rather than very hot drinks, as high temperatures can affect some of the ingredients.
We truly appreciate you taking the time to share your experience.

I was desperate to find something …
I was desperate to find something that would help me with horrid menopause symptoms, not able to use HRT
I’ve given it a month before writing a review
Brain fog has decreased
Hot flushes are less
Sleep is better
More energy
They have given me headaches - so I’ve cut the dosage to two a day (which seem to work for me)
Im pleased so far…
