Introduction to Kosbiotic
The brand
Founded in 2021 by Édouard Fabre, Kosbiotic is the result of three years of research in formulation.
The goal? To make dietary supplements natural, effective and scientifically validated, which act on the gut flora and contribute to consumers’ well-being.
At the same time, the brand emphasizes the respect for the environment, with vegan formulas and biodegradable packaging.
The products: the tribiotic concept
Today, the brand offers three product ranges based on patented probiotics, designed to meet specific needs :
- Digest Delight, which targets reducing digestive discomfort and boosting natural defenses
- Calm My Mind, with active ingredients designed to encourage relaxation and support better sleep
- Slim My Body, a supplement aimed at weight loss
These supplements are based on the tribiotic concept. More than a traditional probiotic, this type of product combines three elements with complementary effects :
- probiotics, the core of the product, live bacteria that have a beneficial impact on the gut microbiota
- prebiotics, soluble fibers that serve as “food” for gut bacteria
- postbiotics, which are metabolites produced by probiotics and act as an additional support to enhance overall well-being
I had the opportunity to receive all three product lines to explore them. However, I conducted my test only on Digest Delight, for two weeks. The other products were observed but not tested directly, to avoid any confusion about the effects.

My analysis of Kosbiotic based on 3 quality criteria
1. Nutritional value
Kosbiotic uses patented strains documented by clinical studies
Regarding nutritional value, Kosbiotic performs strongly and, in my view, meets all the important parameters of a good probiotic.
In the Digest Delight supplement, which I relied on for this test, you can find strains such as Lactobacillus plantarum LP01, Bifidobacterium breve BR03, and Lactobacillus rhamnosus GG, widely studied for their positive effects on digestive discomfort related to irritable bowel syndrome.
The brand notably bases itself on the dosages from this clinical study, which produced the following results for 70 people with digestive disorders: a 49.3% reduction in irritable bowel symptoms after 14 days, a 56% reduction in irritable bowel symptoms after 28 days, and a 38% reduction in the abdominal pain index after 28 days.
The other probiotic strains used in the two other products (Bifidobacterium lactis B420, Lactobacillus plantarum Lpc-37®) have also been scientifically studied at the same dosages, which is reassuring for the real effectiveness of the supplements.
Regarding Calm My Mind, the capsules deliver the same dosages as those tested in this study, which observed a 75% reduction in cortisol levels, a 6.4% decrease in perceived stress, and a +6.6% improvement in sleep-related recovery.
Finally, for the Slim My Body product, Kosbiotic uses the dosages employed in this study, which showed a 4% reduction in abdominal fat mass and a 2.4% reduction in waist circumference.
A sufficient number of CFUs
Doses between 10 billion and 52.5 billion CFU (colony-forming units) are far above the minimal active doses, which ensures a sufficient quantity of live bacteria after storage, transport, and up to the end of the products’ shelf life. Despite the natural fragility of probiotics.
The addition of active ingredients, prebiotics and postbiotics to increase effectiveness
All formulas contain fructo-oligosaccharides (prebiotics) and sodium butyrate (postbiotics) to nourish and support the action of probiotics.
In addition, each product incorporates some targeted active ingredients:
- Digest Delight: dandelion root powder and zinc
- Slim My Body: bladderwrack extract and iodine
- Calm My Mind: Eschscholtzia extract for relaxation
The formulation is well chosen
The brand uses enteric-coated capsules, essential to allow the strains to survive stomach acidity and reach the intestine while remaining effective.
2. Product safety
The production is French, in an HACCP-certified laboratory , which demonstrates a guarantee of quality regarding safety standards.
In addition to the strains that benefit from independent clinical studies, Kosbiotic does perform full tests on the formulas at the time of production, at 6 months and at 24 months, notably to quantify the viability of the strains and the number of strains remaining at the different stages of the formula’s life.
These formulas are reassuring, non-GMO, without controversial additives, and adapt to most diets: vegan, gluten-free and lactose-free.
3. The brand
Kosbiotic has a good reputation: 4.7/5 from 2,533 reviews on Trustpilot, with positive feedback on fast shipping and product effectiveness, notably a reduction in bloating and gas.
The rating is just as favorable directly on their website, and the Instagram community has nearly 24,000 followers.
Regarding transparency, the brand remains relatively discreet. There is little information about the founders, a deliberate choice so that communication focuses on the products.
However, I did have access to the makeup of their strong, multidisciplinary scientific team:
- Head of R&D
- Former research director at a major laboratory (external consultant)
- Scientific and Regulatory Affairs Manager
- Doctor in Microbiology
- Formulator / Pharmaceutical Formulation Engineer
- Pharmacist specializing in nutraceuticals
I think it could be helpful for Kosbiotic to provide a bit more information about these experts to consumers, to better showcase their expertise.
My experience with Kosbiotic
First impression and packaging
I received my package very quickly at home, within 48 hours.
Kosbiotic stays true to its commitment: simple cardboard, kraft tape, no unnecessary plastic or paper. It’s understated, it fits the brand’s positioning, and it avoids having too much plastic and flyers that you always end up throwing away.
Regarding the product’s packaging itself, it is in the same vein: biodegradable cardboard sourced from sustainably managed forests and vegetable-based inks.
Product presentation
Visually, the brand image is coherent. The boxes are aesthetically pleasing and the color codes make it easy to distinguish each product.
The labels are clear and compliant, with all ingredients, dosage instructions, nutritional information and usage precautions easily readable.
The benefits of each active ingredient are stated without promising miraculous effects, which I greatly appreciated.
Perceived effects
I won’t dwell on the effects experienced because they are specific to each individual, depending on their condition, their gut microbiota and lifestyle, and other personal factors.
Furthermore, a two-week course is not enough to fully assess efficacy. I recommend forming your own opinion by trying a probiotic course for at least one month.
However, my initial feedback after this test aligns with customer reports, namely better intestinal comfort and a less bloated stomach, which is encouraging and consistent with the expected action of this type of product. I hope this review is helpful in your search for probiotics!
