Probiotics
Probiotics are live microorganisms, typically bacteria or yeasts, that are administered in adequate amounts to confer a presence in the gut microbiota. They are commonly included in functional foods and dietary supplements.

Probiotics for Gut Health and Digestion
Probiotics are primarily recognised for their beneficial effects on gut health. They promote a balanced gut microbiota by supporting the growth of beneficial bacteria, which can enhance digestion and alleviate digestive discomforts such as bloating, gas, and irregular bowel movements. By maintaining this microbial balance, probiotics contribute to optimal digestive function and may aid in managing conditions like Irritable Bowel Syndrome (IBS) and inflammatory bowel disease (IBD).¹ ² ³
Probiotics and Mental Health
Emerging research indicates that probiotics may influence mental health by supporting the gut-brain axis, a communication pathway between the gut and the brain. Imbalances in gut bacteria have been linked to mental health conditions such as depression and anxiety. Certain probiotic strains may help alleviate these symptoms by fostering a healthy gut environment and enhancing the production of neurotransmitters like serotonin, which is important for regulating mood.⁴ ⁵
Probiotics and Immunity
Probiotics play a crucial role in supporting a robust immune system. By encouraging a balanced gut microbiota, they help modulate the body’s immune responses. Probiotics can stimulate the production of immune cells, which aid in defending against infections and illnesses. Additionally, they enhance the integrity of the gut barrier, reducing the risk of harmful pathogens entering the bloodstream. Maintaining a healthy gut microbiome is closely associated with improved immune function and a lower likelihood of infections.⁶ ⁷ ⁸
How Can Probiotics Support Heart Health?
Probiotics may support heart health through multiple mechanisms. Certain strains have been shown to reduce cholesterol levels, particularly LDL (low-density lipoprotein). Additionally, probiotics may help lower blood pressure by improving vascular function and promoting a balanced lipid profile. By enhancing overall metabolic health, probiotics can contribute to lowering risk factors associated with cardiovascular disease.⁹
