Role of Probiotics in our gut health


People are often confused about how to find the right kind of probiotics. Did you know that every bacteria strain works differently on our body? And that every strain has a specific function linked with it. Read further to know more about them.

What are Probiotics?

Probiotics are a capsuled collection of healthy bacteria that live in our digestive tract. An approximate of 100 trillion bacteria, viruses & fungi reside in our gut and are responsible for various functions.

Think of the gut microbiome as a diverse community of organisms (like as a forest) that work together to keep our body healthy. We host over 100 different species of bacteria, with some being classified as good and others as bad. The relationship with these bacteria can either be symbiotic (life-enhancing for both parties) or parasitic (life-stealing). The correct ratio for health and wellness is considered to be about 85% good to 15% bad. Good bacteria keeps you healthy by supporting your immune function and controlling inflammation.

Certain types of bacteria in our gut:

  • Help our body in digestion of the food we eat
  • Keep the unwanted bacteria from getting out of control and making us sick
  • Create vitamins like B vitamins and Vitamin K in our gut
  • Help support the cells that line our gut to prevent unwanted bacteria that we may have consumed (through food or drinks) from entering our blood
  • Breakdown and absorb nutrients from what we eat

This balancing act is naturally happening in our body all the time. Eating a well-balanced diet rich in fibre and phytonutrients every day, helps to keep the gut microbiome in balance.

There are many different types of probiotics called strains, and each one has its own special function. Every person also has a unique gut microbiome or balance of beneficial bacteria in the gut, so the best probiotic for you may be different from the ideal choice for someone else. To get the most benefits of probiotics, it is critical to identify the most suited strain for your body’s bio-individual needs.
