Key ingredient Morosil®

Real Science
Real Weight Loss

In a 6 month study, subjects taking clinically studied ingredient Morosil® experienced the following compared to diet and exercise alone:

  • 1.8x more weight loss over the course of the study*^
  • 1.8x greater waist size reduction*^
  • Significantly reduced BMI (body mass index)*^
  • Targeted fat loss: Abdominal, visceral, and subcutaneous*^
  • Statistically significant weight loss after first month*^

^Based on a healthy, overweight (BMI between 25 kg/m² and 30 kg/m²) male and female subgroup using 400 mg/day Morosil® versus placebo in a six-month study, in combination with a restricted calorie diet and moderate exercise program.

Morosil® is a registered trademark of Bionap S.r.l.

What to Expect

Thanks to the key ingredient Morosil®, there's 3 major milestones you can expect:

Month 1: significant weight loss
Participants in the Morosil® clinical study started to see statistically significant weight loss within the first month of use, when combined with a calories restricted diet and moderate exercise program.*^
Month 3: targeted fat loss
This trend of significant weight loss in comparison to diet and exercise alone continued into month three. Changes in lean mass were not significant in either group, indicating a trend in weight loss from fat, not muscle in the Morosil® subgroup.*^
Month 6: slimmer waist & hips
After 6 months of continued use, the Morosil® subgroup experienced the below benefits compared to diet and exercise alone:
  • 2× greater weight loss*^
  • Significant reductions in BMI*^
  • Abdominal, visceral and subcutaneous fat loss*^
  • 1.8× greater reduction in hip size*^
  • 1.8× greater reduction in waist size*^
Both groups maintained lean mass throughout the duration of the study, further pointing to weight loss from fat in the Morosil® subgroup.*^

What kind of results can I expect?
Weight loss, targeted fat loss, and reduced BMI were all results seen by participants in the Morosil® clinical study. But to put that in more tangible terms, the centimeters you could lose equate to dropping a full pant size! Plus, when you fuel your body with protein, you should curb hunger and feel more energized.*^

How do I take it / make it?
Mix 1 scoop of Flat Tummy Shakes with about 8 ounces of cold water. Shake and enjoy! Pro tip: you can swap cold water with another liquid of your choice – unsweetened vanilla almond milk is delicious.
What does it taste like?
Chocolate Flat Tummy Shakes taste similar to a perfectly made hot chocolate, just served cold of course. Vanilla Flat Tummy Shakes have a sweet vanilla bean-esque taste.
Why did you change formulas?
After reviewing feedback from our squad, we decided to improve on taste and texture. We did this by ditching plant-based protein and upgraded our formula to whey protein. We took it a step further, and are now bringing you cutting-edge benefits in the form of clinically studied Morosil®! Safe to say, this formula has a 100% satisfaction rate around the office so far.
What is BMI?
BMI stands for body mass index. It is the measurement of body fat based on height and weight in adults. BMI is just one way to measure body size, and it’s important to remember that all bodies are unique and valuable, regardless of their BMI. Embracing and caring for your body in ways that feel good to you is what truly matters! However, it is a useful metric that can help catalogue your current state and progress over time, and maintaining a healthy BMI is important for long term well-being.
Can you taste the orange from Morosil®?
Although Morosil® is our star ingredient and is extracted from blood oranges, you will not be able to taste orange whatsoever. Pure chocolate or vanilla flavor bliss.

I love this product

I'm a real customer who spent my own money. This isn't a paid review. First I'm not a shake type of gal, so I really didn't think I would like it. But oh boy was I wrong. Vanilla is my favorite. I'm looking to order the big container they use to sale. The website has updated a lot. My first purchase was back in 2023. I also love the tea and gummies. These are all my favorite items from Flat Tummy. Consistent is key. Now I'm on a consistent journey for wellness and health Flat Tummy Is definitely a product I'll highly recommend. I don't have any pictures or videos at the moment but I'll get some and return here with results. Thanks Flat Tummy for a great product that fits my needs. 5 starts

Does it really work?

Yes it does work I'm just confused as to why they took the fruits out, why they add a huge scooper to the bag & why is it ONLY 15 servings when the claim it will be 20 servings? Something isn't adding up...

I love it but……

The shakes are supposed to be 20 servings but it’s not ! I drink 1 shake per day Monday - Friday (breakfast) but it never makes 20 servings the first time I thought it was a glitch and then I ordered a second bag it still doesn’t make 20 servings and o use the scoop that’s in the bag ! I haven’t ordered in a while because of it ! The taste is good but I like the old formula better it was more filling! I wish both options were available then we would have a choice of which one we wanted!

Thanks for your feedback! We can assure you that each bag of Flat Tummy Shakes contains 20 servings. Our team is very vigilant about making sure every program includes plenty of product. Just be sure your scoops aren’t heaped, they should be leveled for accurate servings.

As for the old shakes that came in tubs, we can confirm those won’t be making a return. We hope to see you crushing your goals with us again soon!
