The next generation postbiotic will allows you to manage the core aspects of skin health
How is Your Muscle Health?
The answer is 'muscle'. Unfortunately, as we age, our bodies gradually lose muscle, and our physical performance declines. Fat clings like an uninvited guest to the places where muscle used to be. The way to break this unfair cycle is surprisingly simple: cherishing and maintaining our muscles, the most important engine of our body.
Trends Tell Us It's the Era of 'Defending Muscles'
Furthermore, we cannot ignore the rapid rise of GLP-1 based weight management therapies. However, a fatal shadow called 'muscle loss' hides behind this miracle. As a side effect of weight loss, countless people are suffering the aftermath of 'skinny fat' or a rapid decline in muscle mass[2]. Smart consumers now deeply realize the importance of muscle over the number on the scale. The fact that the number of new F&B products in 2025 containing protein and at least one additional functional benefit increased by 32% proves this[3].

Next Generation Probiotics: What is Akkermansia?
With the rapid advancement of microbiome analysis technology, new microorganisms with powerful potential have been continuously discovered in both academia and the market. Among them, Akkermansia muciniphila was discovered only about 20 years ago but is receiving overwhelming attention worldwide[4].
Akkermansia muciniphila is an anaerobic commensal bacterium in the gut that uses 'mucin', a key glycoprotein component of the intestinal mucus that protects gut epithelial cells, as its energy source. Interestingly, while consuming mucin, this bacterium stimulates the gut epithelial cells to promote the secretion of new mucin[5]. Cleaning up old mucin and producing fresh new mucin, imagine how robust the gut barrier will become! This 'strengthening of the gut barrier' is the starting point of the numerous benefits Akkermansia muciniphila provides to our body.
The 3 Key Functional Components of Akkermansia muciniphila
Recent studies are continuously revealing the functional potential of Akkermansia muciniphila. These effects are largely associated with three core components[6]:
- Amuc_1100 (Outer membrane protein): Binds to the receptor (TLR2) of gut epithelial cells to tighten intercellular junctions. The reinforced barrier, blocks toxins (LPS*) from entering the bloodstream, reducing the body's inflammatory response, and improving insulin resistance.
* LPS (lipopolysaccharide): A complex of lipids and polysaccharides present in the outer cell wall of Gram-negative bacteria, commonly called 'endotoxin'.
- P9 (Secreted peptide): Binds to the glycoprotein (ICAM2) of gut cells, which directly stimulates enteroendocrine L-cells*. Through this, it promotes the body's endogenous GLP-1 secretion, acting as a key player in assisting insulin secretion, suppressing appetite, and normalizing glucose metabolism.
* L cell: Intestinal secretory cells that detect nutrients and secrete various hormones, including GLP-1
- SCFA (Short-Chain Fatty Acid, Acetate and Propionate): Stimulates receptors (FFAR2-FFAR3) of gut cells to induce additional secretion of GLP-1 and GLP-2. It is also a reliable supporter that promotes mucus production from Goblet cell to protect the gut barrier.
* Goblet cell: Columnar epithelial cells that secrete mucin to protect and lubricate the intestinal mucosa
Functional Even Beyond Live Cells: The Advantage of Postbiotics
Even this seemingly perfect Akkermansia muciniphila had one fatal weakness. Being an 'anaerobic bacterium' that hates oxygen, it is difficult to process and consume in a live state. However, research has shown that Akkermansia muciniphila can exert its functional benefits even in an ‘dead cell’ state[6]. This characteristic makes it particularly suitable for postbiotic applications. In particular, BiomeNrich™ POST M005 is produced using a proprietary processing technology that ensures the intact cell structure of Akkermansia muciniphila is preserved until it reaches the gut. This approach allows POST M005™ to maintain its functional potential while offering stability for application in a wide range of product formats.
CJ BIO’s clinically backed muscle solution, BiomeNrich™ POST M005
BiomeNrich™ POST M005 demonstrates muscle health benefits supported by scientific evidence from in vitro, in vivo, and human clinical studies.
POST M005™ may contributes to muscle health by promoting the expression of Follistatin, which antagonizes Myostatin, a factor that causes muscle protein degradation[7]. Myostatin binds to its receptor and inhibits the AKT/mTOR* signaling pathway, leading to an increased expression of the FOXO transcription factor, which in turn induces the production of Atrogin-1*[8]. By binding to Myostatin and suppressing its activity, Follistatin ultimately prevents muscle protein degradation.
Furthermore, Short-Chain Fatty Acids (SCFAs), the metabolites actively produced by Akkermansia Muciniphila, also play an incredible role. SCFAs such as propionate and acetate, are known to directly inhibit the expression of Atrogin-1 and promotes AKT/mTOR pathway6.
* The AKT/mTOR signaling pathway: A cellular mechanism that drives protein synthesis, cell growth, and survival, serving as the primary driver for muscle building and maintenance.
* Atrogin-1: A key enzyme that causes muscle atrophy (muscle loss) by promoting the degradation of muscle proteins.
In vitro
In human myoblast and myotube models with induced muscle atrophy, treatment with POST M005™ suppressed muscle cell death and demonstrated the potential to improve functionality related to muscle strength[7].
* Key Study Results:
A significant 40.7% increase in Follistatin* expression in the POST M005™ treated group.
A significant 29.9% decrease in Atrogin-1 expression in the POST M005™ treated group.
* Follistatin: An antagonist of myostatin (which inhibits muscle growth), playing roles in muscle regeneration and angiogenesis.
In vivo
The efficacy of POST M005™ has been validated through two distinct in vivo models: the aging mouse model and the Dexamethasone-induced mouse model. The Aging model captures the complex, chronic nature of age-related muscle loss. It reflects the physical decline driven by mitochondrial dysfunction and an overall slowdown in metabolic capacity, which leads to a decrease in muscle protein synthesis. Dexamethasone is an anti-inflammatory and immunosuppressive drug commonly used to treat conditions like allergies, atopic dermatitis, and rheumatoid arthritis. However, it triggers rapid and acute muscle protein degradation by suppressing the AKT/mTOR signaling pathway and promotes the expression of Atrogin-1. By conquering both in vivo models, POST M005™ has scientifically shown itself to be the comprehensive solution for muscle health.
In vivo-Dexamethasone induced model[6]
The intake of POST M005™ resulted in a significant increase in grip strength, muscle mass, and the cross-sectional area of muscle fibers in mice induced muscle atrophy.
