Before and After Stories Directly From Thousands Of Women

Incredible success

Within 2 days I noted reduction around hips. At 5 days I could see my whole body was smaller. My fave looked as if I had a facelift, dropping eyelids lessened, jowls less slack. By day 10 I was receiving hourly compliments about how well I looked. I remeasured myself & had lost weight bust/ waist/hips. My long-standing belly bulges (upper & lower) were reducing. Weight is unchanged but I'm a different person. I'm simply astonished

This product works!

I've been trying Complete Gut repair for 3 weeks now. After 1 week, I felt I had more energy overall, small improvements on my skin and breakouts, and some nights having a better, deeper sleep. Looking forward to continuing using and get full and long term improvements. Over the years I've tried a large number of pre-pro biotics, organic remedies but none is comparable to this. I would definitely recommend and will be buying more.

Gut Repair

Many things can upset your stomach and digestive system. I love this Gut Repair. You just add one spoon to your favorite beverage. I drink this all day long. It's particularly good mixed with the Tea. I love the vanilla flavor! I love so many of the Happy Mammoth products that go with the plan. They do aid in healthy weight loss as well. I highly recommend. It tastes great and really works! I have lost 5 kg in 8 weeks. My daughter has lost weight too! We both enjoy this new way of eating and it's definitely life changing. I've found that within my friends and family they either love it or do not. There is no in between.


Have tried many remedies for bloating, gas. This powder is amazing and even taste good. I look forward to it in the morning. No more bloating even if I've been eating lots of broccoli. I can't recommend it enough. My son is also taking this super powder and has noticed a remarkable difference in his body and movements.

Best supplement

I've been using gut repair for 3 months. I've lost a stone in weight and I have beautifully flat tummy which I haven't had for years! I've been struggling with food and bloating but now I don't have that problem. I can't live without this supplement, two scoops per day has changed my life... So thank you happy mammoth!

Amazing product

I saw a post on FB advertising this amazing product and decided to give it a go! What a GAME CHANGER! You have no idea how much this means to me I am now back to my old self back running 10k's/Marathons! I wish I could give you all at Happy Mammoth a MASSIVE hug to thank you for making such an amazing product please keep up with the good work.

How Complete Gut Repair™ Help Support and Restore Gut Health - Right From Day 1

Here are the ingredients that make this formula so powerful… And how they work together to help you get your old self back:

Hydrolyzed Collagen Peptides

Shown to support gut health and help promote healthy gut flora, which is essential for gut function*

Collagen is abundant in essential amino acids that play a critical role in supporting your gut health* It works like a nutritional "super glue" that holds your gut together.

BONUS: Collagen also makes your skin tighter and brighter, and your hair stronger, thicker, and fuller.*


This is a vital component of your gut lining, so adding L-Glycine to the formula helps to support it.*

L-Glycine is supported by an impressive amount of scientific research that shows its critical role in helping people support their collagen levels.*

L-Glycine has been shown to promote nervous system health and support an overall wellbeing.*

L-Glycine is also an excellent natural sleep aid. It promotes restful sleep and help maintain healthy sleep patterns. This means it may make it easier to fall asleep and stop waking up at night.*

SBO Probiotic Bacteria

Support your entire digestive system with this “everyday” probiotic*

Boosts your gut with 300 million beneficial gut bacteria in every serving… To promote a healthy gut flora that may result in smoother digestion.*

Bacillus Coagulans have been shown to help relieve various symptoms which include occasional bloating, gas and diarrhea.*

They also may help maintain healthy digestion, immune system, overall health and healthy functioning of the gastrointestinal tract.*

In other words, they’re an important nutrient for every woman looking to maintain health, happiness and energy levels.*

Pureway® Liposomal Vitamin C

Higher absorption Vitamin C*

This is a unique, patented form of vitamin C is shown to have 233% higher absorption than other sources!

Vitamin C helps the body build collagen at a cellular level.*

Vitamin C boosts the absorption of collagen in the formula, so you can make the most out of Complete Gut Repair.*

Vitamin C is extremely difficult to absorb by the body, but the patented PureWay Vitamin C is the most bioavailable, potent form on the market.*


L-Threonine is an essential amino acid that helps to protein levels in the body.*

Essential amino acids like threonine are the building blocks of proteins. They play a vital role in the structure of our bones, muscles and skin.*

L-Threonine is critical for supporting the mucus layer inside your gut*

Supports gut health, bone and muscle strength.*

Patented Prebiotic Fiber Preticx®

 The Superfood For Your Gut Flora

Prebiotic Fiber is superfood for the beneficial bacteria in your gut. It feeds them to support gut flora* and promote balance of the microbiome.* It perfectly matches the probiotic bacteria in the Complete Gut Repair formula — because it’s been shown to support its growth in the gut.*

Simply because it’s one of the best prebiotic fibers available right now. And this has been shown by a study from UCLA.* In the study, the scientists found that PreticX effectively supports the gut microbiome*

What’s more, it’s been shown to go hand in hand with the Prebiotic Bacteria in the Complete Gut Repair formula to help promote regularity, nutrient absorption, and to help maintain blood sugar levels.*

This may translate to smooth digestion, increased energy, and amazing mood. Plus… it can help assist with weight loss.*
