Probiotic supplements are capsules or tablets that contain living bacteria. These specifically consist of ‘good’ bacteria that form a vital link in the chain of processes that break down and absorb the food we eat. These supplements have exponentially increased in popularity in recent years, with innumerable providers proliferating a vast number of distinct probiotics for myriad purposes. As humans, we can rarely identify what processes are occurring within our digestive systems. However, if everything operates sufficiently, our different organs and systems operate together to subsume energy and nutrient from food to support the body’s multiple functions and overall well-being. 

The first step in the process is eating. We manually break down our food by chewing, whilst our saliva softens the consistency. Subsequently, stomach acids break down food components that are further degraded and oxidised during the digestion phases. Finally, ‘good’ probiotic bacteria in the intestines finalise the process. However, the natural probiotic bacteria that live in the digestive tract can be harmed when we are ill, take medication, or make poor lifestyle choices. When this occurs, we can experience several detrimental symptoms, such as flatulence, bloating, diarrhoea, constipation, abdominal pain or discomfort. In these cases, it is highly recommended to adopt a probiotic supplement to boost bodily processes, promote optimal digestion, and replace bad bacteria with good bacteria. This article will review the most popular probiotic supplements and evaluate their benefits. 

Probiotic supplements

Probiotic supplements are typically available in capsule form, containing several distinct types of live probiotic bacteria. In addition, they can contain vitamins, minerals, or other beneficial nutrients.

Before adopting a course of any supplement, it is recommended to consult your doctor for dietary advice. Many supplements also contain prebiotics (plant-based fibres that enhance good gut bacteria).


Prebiotics refer to the organic fibres that probiotics in your digestive system consume for nourishment; fruits, vegetables, and whole grains are superlative sources of prebiotic fibre. Due to their tough, substantial consistency, fibres in foods are rarely fully digested immediately - they pass through the digestive system without being absorbed, ‘bulking out’ and improving the texture of food material.

Unfortunately, modern diets tend to contain higher levels of processed food and not enough natural foods that are high in fibre. If you are an individual who consumes a low-fibre diet, taking prebiotic supplements can greatly benefit your digestive health.

Final thoughts

Ultimately, if you consume a healthy and balanced diet, many of the superfoods integrated into your diet will naturally provide the probiotics your body requires. However, in reality it is challenging to ensure that the food sold in supermarkets and restaurants is inherently high in quality – the beneficial nutrients in many foods are partially or entirely destroyed when food is refrigerated, cooked, or stored for long periods. 

Therefore, similar to any other supplement for health (such as cod liver oil or A-Z multivitamins), some nutrients are more difficult to source and maintain in your body. Probiotic supplements contain the precise balance of components the body requires in one compact capsule. It is therefore critical to thoroughly research available options before committing to a course of gut health supplements and consider consulting your physician or healthcare provider to identify which ingredients will benefit you most.
