The prebiotic collagen protein definitely makes me feel a bit better. I’m older, I must have support for my damaged foot and legs. Additionally, the probiotic is necessary after getting a severe gut infection and being hospitalised in Koh Phi Phi… Read more ·  1

five months ago. I first bought this product in Australia. But now in NZ, I ordered it here and the process was straight forward. Please also develop an affordable and truly high strength nattokinese product for blood, heart and brain health. People over 60 require slightly different support to ensure that we can have active and healthy lives until we are 100.

 Follow-up  · Pro biotic collagen is an easy to use product, either use a shaker or stir it into a glass. The taste is inoffensive, no horrible cough mixture cherry flavour! I use it when I wake up and I allow at least half an hour before having coffee and breakfast. My general well being is a bit better, my legs aren’t so achy. When I’m very physically busy around the property, I’ll ensure I take this product. Also, before and after I travel.

My last three orders have been botched. Unfortunately, it takes a representative several weeks to respond and therefore, the consumer has to buy additional items to continue to stay on the program while the replacement order has not been delivered and it's been 2 months wait so far...

 Follow-up  · As I promised, I stopped buying their product.

The 60 day gaurantee is a sham. Olease do not purchase this product under their false pretense of satisfaction guaranteed or yo ur money back. Each jar holds a 24 day supply, needing 3 jars at least for the 60 day “trial”. When i tried the Hormone Harmony andEeight Control and did NOT have positive results after 48 days, I requested a refund. They… Read more

only honored one of the six bottles saying that there is no 60 day product trial or your money back. Here is the email from Toni who responded to my inquiry wherein i expressed dissatisfaction and a gain of 4.2 lbs:

Thank you for your response and for taking the time to share your experience with us. ☀️

I'm sorry to hear that our products didn't work out for you and I truly understand how frustrating this situation must feel, especially after making your purchase with the expectation that the 60-day money-back guarantee would allow you to fully evaluate the product with peace of mind.

I want to sincerely apologize for any confusion or disappointment you’ve encountered. We absolutely value transparency and take our commitment to our customers well being very seriously.

I appreciate you explaining the steps you took and the reasoning behind your purchase, as it helps us better understand your perspective. I can confirm a refund for one jar of both Hormone Harmony and Ultimate Weight Control has been refunded under our guarantee. This will be reflected in your account within the next 2 to 5 business days. Our products have a 60-Day Money-Back Guarantee, which only applies to the 1-jar option. You can check our policies by going to Support / Returns and Exchange Policies / How does the 60-Day Money-Back Guarantee Works? You can find those details here: https://store.happymammoth.com/pages/support

As a one-time exception, if you ship back the remaining unopened jar/s, we can issue a refund for these if returned in the same conditions as when first sent. As per our policy, we kindly ask you to provide us with a photograph of each unopened product. The picture should showcase the product itself beside their original packaging box if applied (Glass jar+box - please refer to the attached image) - Returns for multiple jars/tubs of the same product: Please provide one photograph with all of the jars/tubs together. In order to avoid delays; the photograph(s) must be in good quality/clear, and the whole product must be visible. Please be aware that our team reserves the right to reject your return if the product has been opened, lacks the plastic ring seal (if applied), or if the original box is missing or damaged (if applied). A product should be in the same state as it was when you first received it. Upon receiving all the necessary information, one of our agents will promptly forward it to the appropriate department. We will then keep you informed about the subsequent steps in the process. Just let me know how you'd like to move forwards, and I'll do everything we can to help you. Please reach out to me if I can help you with anything else in the meantime. Yours in health and happiness, Wishing you a Merry Christmas Tony

I have been taking Happy Mammoth products for several months now. I started with Hormone Harmony and noticed the difference in my mood in less than 2 weeks. I found myself happier with my teenagers, which is an amazing result in itself!, and even my husband noticed my moods had improved with him. I then started Fatigue eliminator which was to… Read more ·  1

help with late night driving as the teenager’s taxi runs are so far and regular. Again, this worked in a very short amount of time. These pills are not miracle cures but they make a very noticeable difference. I don’t feel the exhaustion that I was suffering with before. After my success with both of these products I decided to try the metabolic harmony. I have lost an inch around my waist and my waistline looks less saggy. I’m not a big person but I’m 55 and my body has been changing. I feel this has helped a lot. So far, I’ve been very happy with the products, I just wish they were a little less expensive as it’s a lot to fund every month!

I'm trying to work out the best products for me. I've gained weight over the years, this can be attributed to menopause, stress and life in general. I started with Complete Belly Reset. This is an amazing product that keeps me regular and I'm noticing that my body shape is changing. A friend recommended that I try Hormone Harmony. I think that… Read more

this has been a game changer, even though I didn't think that this was the actual problem. I'm sleeping better, have more energy and just seem to be more focussed. Ultimate Cravings Control was released again so I thought that I'd give it a go. I think that this would be a great product, however, I don't really crave anything. Not into lollies, chocolates, sugar etc. My go to are nuts which can be a problem if eaten excessively. They have just released Ultimate Weight Control which I will also try, however, I think that my daily routine will include Complete Belly Reset and Hormone Harmony. It's great to have found products that work and aren't harmful.

I found this on instagram and thought it can’t work but tried it because of the money back offer. I have to say within weeks my bloating had decreased and my tummy looked flatter. I stopped taking it after a while as thought I had plateaued but am going to restart to see if the bloating goes again Show reply

Happy Mammoth Ultimate Weight Control didn’t work for me. I took it for six months with zero results. No weight loss, no curbing of hunger /sugar cravings, no help with bloating. You must take three large pills a day. If anything they upset my stomach, making me feel to eat something to calm it down. It’s very costly, even with subscription. … Read more

I felt lighter and slimmer, however the prebiotic Collagen protein has given me an allergic reaction. If you have a sensitive immune system, I would avoid this product. I'm not allergic to beef however the bovine collagen ingredient has given me a severe reaction. Be careful. The refund policy does not allow a refund if an allergy presents.

I felt that my mood had picked up only after a few days after I started taking them. However I am now on my second week and I am waking up at 3 am and can not get back to… Read more

Started using this product a few weeks ago. I’m actually really amazed at the impact it’s had. I don’t feel lethargic and sluggish all the time. I’m back to a normal level of energy which I didn’t think was possible. I’m calmer and able to function. I’ve tried pharmacy products that didn’t work but this actually does.

Disappointed with the delivery service Happy Mammoth chosen courier Aramex. Fan of product but the ongoing issues with delivery have been incredibly frustrating and time-consuming. The order has been in transit for two weeks, and despite multiple attempts to contact Aramex (reference #95166616), there appears to be issues still. The most recent… Read more

communication with Aramex, indicated that the issue had been resolved and delivery would be made within a day but that did not happen. Post office pickup was arranged by me for deliveries, given limited time availability, convenience, and security. However, it appears that Happy Mammoth has chosen to utilize the delivery service, Aramex, that won’t accommodate this arrangement. This information was not communicated in Happy Mammoth. I have contacted Happy Mammoth & Aramex on several occasions and I’m wasting time going around in circles with that same responses but no results. Frankly, I’m angry and want some real customers and real results.

I'm continuing to try more of the Happy Mammoth product line. This review is for the Newslim Supergreens. It's a great way to get your greens and probiotics in one great tasting drink. I enjoy not worrying if I eat enough veggies everyday, I don't need to buy a separate probiotic supplement and I'm supporting my weight loss goals. I plan to continue trying more Happy Mammoth products. Show reply
