At the centre of a healthy digestive system is a well-kept gastrointestinal (GI) tract or the gut, a tube that runs from our mouth to our anus.

The gut, or intestine, allows us to absorb nutrients for the body and remove harmful toxins and waste materials.

But the benefits of a healthy digestive system go far and beyond merely contributing to the balance of nutrient retention and disposable of toxins.

It also tantamount to maintaining overall body health. (1)

Benefits of A Healthy Gut

Better Stress Management

A common symptom of a body under stress is diarrhoea.

A body under stress will experience a weakening of the immune system, which is closely linked to digestive health.

This may result in poor functionality of certain bodily organs, leading to or compounding on other health problems.

Hence, a healthy digestive system will help to ward off stress-related ailments. (2)

Greater Energy

Under optimal conditions, the body uses 80% of your energy to digest foods.

This figure increases in times of stress or illness, leaving less energy for the body’s other important functions. (3)

One of the ways to maintain this necessary energy level, is to supplement our diet with an intake of probiotics. (4)

Recovering from Antibiotics

Antibiotics work by killing off bacteria that cause infection but they also eliminate friendly bacteria from the

digestive tract at the same time. (5)

A probiotic supplement helps bring back the balance of good bacteria, which will help to restore the health of our digestive system. (6)

Beneficial Friendly Bacteria

Our gut contains both good and bad bacteria.

It is important to note that a balance of good and bad bacteria is essential for optimal health.

Once the balance between good and bad bacteria is affected, our bodies become less efficient in absorbing the nutrients they need, resulting in further digestive and health problems. (7)

Essential good bacteria in our bodies include:


– Produces lactic acid which alters the intestinal environment, making it not conducive for pathogenic bacteria to grow. (8)

– Studies show that Lactobacillus improves lactose digestion, which suggests that it may help those who are lactose intolerant. (9)

– Reduces incidence of diarrhoea due to changes in eating habits or stress. (10)


– The first line of defense against bad bacteria such as Salmonella and E-Coli.

– Produces lactic acid which discourages the growth of harmful bacteria to protect intestinal cell integrity and maintain good intestinal health.

– Produces immunostimulating properties, which reduce the incidence of diarrhoea and help reestablish a proper balance of intestinal health. (11, 12)


– Supports digestion of dairy products.

– Reduces lactose intolerance and incidences of diarrhoea. (13)

Understanding Probiotics and Prebiotics


Live organisms that helps improve the environment of the intestinal tract

Help maintain microbial balance in the intestines

Help inhibit the growth of harmful bacteria

Lactobacillus, Bifidobacterium and Streptococcus are probiotics. (14)


Food sources that stimulate the growth or activity of friendly bacteria in the intestines.

Not digested by the human digestive enzymes, hence they pass through the intestine unchanged, enabling probiotics to utilize these prebiotics as food sources.

Help stimulate growth of friendly bacteria.

Can be derived from non-digestive fiber, eg. inulin, raffinose, galactooligosaccharides or fructooligosaccharides. (15)

Probiotics (e.g. Kefir, Cultured Vegetable, Kombucha, Yogurt) + Prebiotics (e.g. Raw Garlic, Raw or Cooked Onions, Under-ripe Bananas) + Amount of Organisms (Gut Flora) and Dual Coating (Technology to improve survival of probiotics) => Beneficial to digestive and immune system
