How does Koso Work?

Gut health points to the balance of good microorganisms that live in the digestive tract. In recent years, scientists have discovered that the gut microbiota has been linked to many aspects of health relating to digestion, from immunity to brain and mentality, to chronic illnesses, including cancer.

Gut health points to the balance of good microorganisms that live in the digestive tract. In recent years, scientists have discovered that the gut microbiota has been linked to many aspects of health relating to digestion, from immunity to brain and mentality, to chronic illnesses, including cancer.

What are Postbiotics?

Gut health effects immunity system

"When gut health is good, you’re less likely to experience damaging inflammation and lapses in immunity."

Probiotics helps to improve mood

"Some research has found that probiotics may help boost mood and cognitive function and lower stress and anxiety. "

Your gut and brain are connected

"Your gut and brain are connected physically through millions of nerves, most importantly the vagus nerve. The gut and its microbes also control inflammation and make many different compounds that can affect brain health."

Healthy Gut = Weight Loss

No doctors argue that a healthy gut leads to healthy weight loss. R's KOSO is the easiest way to gut cleanse. No extra supplement is needed. Prebiotics, probiotics, postbiotics, and all micronutrients are in the bottle.
