Purchasing the complete gut system or the trio, collagen reds and greens. It didnt agree with my body and upon asking for a refund, was told there was no refund. So these products are not backed by confidence, why would you say on the website there is a double refund if there is not, their advertising is misleading and we all know a product that is good does not require the bullying and holding onto the money from the customer. Products that dont suit and we cant know that until we try should be refunded, no questions asked. Big legitimate comp...

Reduces abdominal bloating and discomfort significantly. It is great in my morning smoothie which disguises the bland taste. My skin also glows after using this product. I would recommend trying it.

Great reviews however this product unfortunately just did not work for me. I just finished the container and I didn’t notice any difference with my bloating, complexion, tiredness. No benefit at all.

I love how this collagen powder dissolves really well, tastes great and isn't gritty. I've been taking this product alongside the Happy Mammoth L-Glutamine and it has pretty much cured my leaky gut! Can't live without this stuff now!

As I'm going through early stage menopause, I'm finding that I used to bloat a lot and have digestive issues. Since day 3 of taking this product, I have NOT had a single day of bloating, upset stomach or experienced many digestive upsets (unless I forget to take it)! I cannot live with out this product! I love it!

I had constant upset stomach and this product has fixed my issue. My stomach was like a washing machine and this product has fixed what ever issue was going in, I take it every single day and love it

I have IBS and gastritis. I have found the product to be very beneficial with these issues. I take it twice a day. My skin and hair have improved a bit also, but that took some months to notice. However the gut issues eased after the first month or two. I find the taste just fine. I mix it with some Vit C powder. Highly recommend.

I am taking this product because I have bloating/digestive problems. I also buy their other best product "L-Glutamine". They have both helped me with bloating and leaky guts. I have Crohn's desease so I wanted products that are both natural and effective. I love the Prebiotic vanilla flavour! It mixes very well with smoothies. It adds a little bit of sweetness, but not too much and it's super yummy! To my opinion, they are some of their best products. You can't go wrong! The service and delivery are both very good too :)

I Love that I can take one product to help with the health of not only my immunity and my gut health (prebiotic) and my aging body (protein). No longer do I suffer the agonising pain of diverticulitis because of this amazing product. I love that its Australian made and the natural ingredients. Also the taste is so delicious, just like a salted caramel milkshake without the bad stuff. Menopause is a nightmare but with this product I know my gut health and my bones are getting what they need. Love all their products and they have second to none c...

After many years of awful gut problems, I decided to try this and I am so glad i did. Prebiotics are so important and have changed the terrible bloating I used to get. This is a pleasant tasting smoothy (I use with skim milk not water) and it worked quickly. thanks Happy Mammoth.

After suffering from IBS and menopause, this prebiotic collagen protein powder gave me the energy I was after to assist with my health, noticed a huge difference even after taking it for a short time with no adverse reaction.
I would recommend this product,

This product has literally changed my life! After having severe IBS for most of my life, this product has reduced bloating, cramping and most of all upset tummy problems. As soon as I stop taking it, my symptoms return. I am a huge fan!

I have been taking Prebiotic Collegen Protein for over 12 months. I have less bloating & gut problems. My last Gastrocopy showed no inflammation section with my Barretts Esophagus. I was quite surprised to hear this as it was the first time in 12 years. I mentioned this to my Dr & replied to keep doing what I'm doing & that is to continue with this fabulous product.
Thankyou Happy Mammoth for your ongoing support & instant response to any questions I may have.
And best of all it is an Australian made product.

The Prebiotic Collagen was my life changer after years of stomach problems. Within days the constant pain and bloating in my stomach had subsided. I had a break from the powder and sure enough symptoms returned within a few weeks. So I know how well this product works and certainly am very impressed with its effectiveness.

I started taking Happy Mammoth's Probiotic Greens about 3 months ago and definitely feel less bloated and have more energy. I also tried the Prebiotic Collagen Protein for 1 month, and while I didn't notice a huge difference my skin did look and feel better. Certainly there were no side effects or negatives and I will order again with my next order of Probiotic Greens.

Im on my third tub of Prebiotic Collagen Protein. I have found it has settled my stomach and bloating after the first week. I simply add a scoop to my oats each morning for breakfast.

I have suffered from IBS and bloating for years. Pain in my gut caused so much discomfort! I had a Colonoscopy, nothing appeared to be causing it. I started taking Prebiotic Collagen Protein powder, 3 months ago, and I have no pain with no side effects! I told my Doctor and he was impressed. I've just recommended it to my best friend.

I have been using the Prebiotic Collagen Protein for about 3 years, I have found it to be very beneficial to alleviate digestive issues after surgery. I tried a number of over the counter probiotics which did not agree with me at all, but I have found this has worked so well for me. As a bonus it has also helped with my skin and nails. I love adding it too my smoothie or chia pudding, but also happy to just eat it on it's own with water. I have also gotten my sister onto it and she loves it too!

Tastes great, does it’s job, fills you up and calms the gut all whilst providing you with extra collagen, what’s not to like?!? Highly recommend this Happy Mammoth Product to anyone thinking of giving it ago

I started taking this product 12 months ago and I love it. I have an autoimmune disorder that takes a lot out of me so I always found my skin, hair and nails were always dull, dry and brittle, but 12 months on I have grown my hair, I have colour back in my skin, definitely got a glow to it and on op of all of that, my gut has improved, its been fantastic. I have added in other products from Happy mammoth and it has improved again. Love it all.
