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 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…

I’m currently on my third bottle of…
I’m currently on my third bottle of Happy Hormone Plus, and I wanted to share my experience for anyone else going through perimenopause.
I’m 47 and started having symptoms that didn’t feel “typical” — I had this constant pressure in my chest that felt like anxiety, unexplained weight gain in my midsection, poor sleep, and overall just didn’t feel like myself. It was frustrating and honestly a little scary at times.
After doing some research and speaking with my gynecologist, I decided to give this supplement a try while also moving forward with bloodwork and hormone testing.
Now going into month three, I can say I’ve noticed a real change. The chest pressure I was experiencing has drastically subsided, which has been such a relief. I’m also starting to sleep better at night, and that alone has made a big difference in how I feel day to day.
As for weight, I’ve only lost a few pounds so far, but I can tell my belly is starting to soften again, which gives me hope that things are moving in the right direction.
Overall, I feel more balanced and more like myself again. It hasn’t been an overnight fix, but the steady improvement has been encouraging and worth it.
If you’re dealing with similar symptoms, I’d definitely recommend talking to your doctor and considering this as part of your plan. It’s been a helpful support for me during this transition.

Total Scam!
I am giving zero stars. This product provided hope thru the adds, a promise of 60 days to try the product or get your money back, then a deal to purchase more bottles so that you get a deal! Don't fall for it! It did not work for me at all! I followed instructions to do a return within the 60 days, sending pics of the bottle and boxes for both of my bottles, one new and other 3/4 full. I purchased tracking, the happy mammoth agent said it was necessary. Jumped through every hoop and then told they are only refunding one bottle. Somehow in my purchasing I should see that with the 60 day money back guarantee, IT ONLY COVERS ONE BOTTLE!
when I explain this to the agents sending me emails, no one wants to work with me on getting the rest of my refund. This is not what I needed on top of the symptoms I am experiencing that this product promises to help. ..... or your money back. Don't purchase this product! Customer Service is horrible!
