They play an important role in maintaining a healthy gut microbiome that further ensures good health. That’s why choosing the right probiotics is necessary to get the desired health benefits.

Why a Healthy Gut Microbiome is Essential?

Our body’s gut microbiome is a complex ecosystem consisting of trillions of microorganisms such as bacteria, fungi and viruses. This microbial community resides in our gastrointestinal tract and plays an important role in maintaining our overall health.

A balanced microbiome facilitates food digestion, promotes proper nutrient absorption, and supports regular and healthy bowel movements.
70% of the immune system is located in the gut, and a healthy microbiome helps in modulating immune response to defend against infections and reduce inflammation.

Research over the past few years has highlighted the connection between the microbiome and mental health, collectively known as the gut-brain axis.
The gut microbiome also influences the way the body processes eaten food and the regulation of energy.

Top Benefits of Probiotic Supplements

If you are thinking about the key benefits of probiotic digestive supplements, they are not confined to one area and extend beyond digestion, ensuring daily nutrition and well-being. Here are the benefits you can enjoy with probiotics.

Prebiotics vs Probiotics in Gut Health: What’s the Difference?

Are you confused about prebiotics vs probiotics and want to know what they do for your gut health?  Both of them play crucial yet different roles in maintaining a healthy gut microbiome.

Prebiotics are non-digestible food components, mainly consisting of dietary fibres, which act as food for healthy gut bacteria. They work like fuel for the probiotics, enabling them to thrive and function effectively. Take a look at some of the common sources of prebiotics:

• Fruits: Bananas, apples, and berries
• Vegetables: Onions, garlic, leeks, asparagus, and artichokes
• Whole grains: Oats, barley, and wheat
• Legumes: Beans and lentils

Probiotics, on the other hand, are live microorganisms ready to provide you with health benefits by working on your gut flora balance. They help improve digestion, boost the immune system, and can influence mental health. Probiotics are abundantly found in fermented foods and are often available as supplements.

When you consume both prebiotics and probiotics, they not only provide a balanced gut microbiome but prevent you from several gut disorders such as constipation, diarrhoea and inflammatory bowel diseases. Create a powerful combination of both to ensure your everyday health and well-being.

Major differences: Prebiotics vs Probiotics

These are the prime differences between prebiotics and probiotics that are worth considering.
