Probiotics are regarded as the gut health superheroes that not only help in digestion but also boost immunity and improve skin health. Some research even suggests probiotics can help reduce body fat, waist circumference, and body mass index (BMI). No wonder, probiotics are becoming a staple in wellness routines. While many are relying on probiotic supplements to transform their wellness, others are adding them to their diet naturally in the form of yoghurt, kefir, sauerkraut, kimchi, as well as in some drinks like kombucha.

Probiotics are live bacteria and yeasts that can benefit your health in a number of ways. In your vast gut microbiota that consists of a mix of good and bad bacteria, probiotic supplements add to the existing supply of friendly microbes. They also fight off the 'bad' bacteria and boost your immunity against infections. Our body is home to trillions of microorganisms that help support our bodily functions and health. Probiotics help prevent and treat dysbiosis — an imbalance or a deficit of beneficial microbes in your microbiome. However, probiotics are not for everyone and may not suit an individual.

What happens when you have too much probiotics
Emerging studies are discussing the long-term effects of daily probiotic use, especially in healthy individuals. Overloading the gut with good bacteria can increase inflammation or pose cardiovascular risks.

A study published in Journal of Functional Foods discusses the lesser-known side effects of consuming excess probiotics.

1. Excess good bacteria can trigger inflammation
While probiotics usually elevate gut health, their long-term use is associated with elevated inflammatory cytokines, which suggests that excess 'good bacteria' may actually trigger inflammation.

2. Change in gut microbiota composition
Prolonged use of multi-strain probiotics shifted gut bacteria toward families associated with gastrointestinal inflammation, including links to diabetes and stroke. Microbial balance was disrupted despite the strains being generally recognized as safe.

3. Increased cardiovascular risk
Long term intake of probiotic supplement use can increase markers like lipoprotein ratios (important cardiovascular indicators) which is a potential warning sign for heart health.

4. Enlarged lymphoid structures
In the said study, while no visible colon damage occurred, rats developed enlarged lymphoid follicles and aggregates, suggesting chronic immune system activation.
