This cleared up my irregularity and it's delicious too!

My husband purchased the prebiotic collagen powder and never used it. After being on a GLP-1 inhibitor, I was experiencing irregularity, which is a common side effect. Tried a half scoop of vanilla HM powder in my coffee and I can't do without it! I'm regular as can be with no other side effects, except for a delicious addition to my coffee. Definitely a keeper.

Hi Samantha,

Thank you for sharing your experience with us. We understand it can feel discouraging not to notice a difference right away, especially when you’re hoping to feel improvements quickly.

At this stage, you’re still very early in the process. For many customers, it can take a few weeks of consistent use to begin noticing changes, and individual responses can vary depending on factors like routine and how your body adjusts.

We’d really like to support you and better understand what you’re experiencing. We haven’t heard back from you with your account details yet, so if you’re open to it, please share them with us at reviews@happymammoth.co or through this platform so we can take a closer look and guide you more personally.

Warm regards,
Happy Mammoth

Hormone Harmony Plus…

I have started the hormone harmony plus because I have started Peri-Menopause. It has already started to help me feel better physically, emotionally & mentally. It was easy for me to get set up on the recurring deliveries and then I dont have to worry running out of it.

Absolute Life safer

I tried the menopause tablets and then they changed it to these plus ones. And can I just say I only take 1 tablet a day. An it’s helped so much with brain fog, anxiety and mine was bad. Sleep, and feeling well in general. I have recommended it to as many women as I can who are going through menopause as I did not want to take HRT. I feel like I’ve got through the height of it and just loving life 🤗 🥰

Great Customer Service

There was an issue with my subscription (thank you, PayPal...), and the customer service people at Happy Mammoth helped me resolve it quickly. They are very professional and knowledgeable; a real pleasure to deal with, especially since I can be a pain in the neck.

Good for annoying bloating.

Been taking these for about 4 months now. Definitely helping with bloating and keeping weight down. Helping a little with mood swings and feeling calmer.

Metabolic harmony is helping my mental health and wellbeing

Well I must say I was very sceptical about trying this product due to the price but it didn't disappoint. I am 49 and deep into perimenopause so I have been experimenting with lots of ways to help improve many of my symptoms over the past few years and I can safely say I think I have cracked it by using happy mammoths metabolic harmony! I am just about to finish my first bottle and because of how successful this has been I have ordered another 2 bottles. I am blown away by how good I feel, the best I have felt in years and feel more like me again. I noticed a difference within the first week but each week just got better. I am into my 4th week and I am so happy. I am using HRT patches which help well but so much more has improved by using the product. My focus and concentration has improved greatly which I really need for my job, foggy head is no more, my energy is just amazing, I am having black out sleeps which again haven't had for years. To top it off as all women at this stage of life know weight is harder to maintain but this really has curbed my sweet cravings helping me to have a healthier diet. I reached for an easter egg just to have one not because I was craving it and weirdly I just didn't enjoy it as much so never finished it......that blew my mind! My husband has really noticed a difference in my overall wellbeing and you just cant put a price on your health and wellbeing. I do wish it was a little cheaper but I also feel I am investing in myself at this time in my life. Absolute 5 star product ✨️

Unrepaceble



I am very pleasantly surprised about Hormone Harmony effect. After few weeks I feel my body is more balanced – mood swings was less, sleep is better and I have more energy for daily life.

I really like that this product is made from natural ingredients – plants, vitamins and minerals, that help body work more in harmony, not agressively change processes.
