Role of Probiotics for Glycemic Control (Diabetes)

Role of Probiotics for Glycemic Control (Diabetes)

Insufficient or resistant insulin production results in the metabolic disease known as diabetes, which is marked by elevated blood glucose levels. It appears that using probiotics is a safe and all-natural strategy to handle the dramatic increase in the prevalence of diabetes. It has been demonstrated that using probiotics to alter gut microbiota has positive effects on insulin resistance and glucose metabolism

How Probiotics Contribute to Control Diabetes

Since they improve oxidative stress and inflammation biomarkers and lower fasting blood glucose by fostering an anti-inflammatory gut microbiota—which is known to be associated with improved metabolic health—a few probiotics, such as Lactobacillus and Bifidobacterium, have been shown to have antidiabetic effects.

Probiotics can help in controlling diabetes through the following means:

  • Better Composition of the Gut Microbiota

Probiotics can alter the gut microbiota by encouraging the growth of good bacteria and suppressing the growth of bad ones. Improved glucose metabolism and overall metabolic health are linked to a healthy gut microbiota.

  • Increased Insulin Sensitivity

Research indicates that some probiotic strains may increase insulin sensitivity, enabling cells to react to insulin more strongly and facilitating the uptake of glucose from the bloodstream.

  • Decreased Inflammation

Diabetes frequently results in chronic low-grade inflammation, which can impede insulin signalling. Probiotics have been demonstrated to enhance glycemic management, improve insulin sensitivity, and lessen intestinal inflammation.

  • Short-chain Fatty Acid (SCFA) Formation

Probiotics can mature dietary fibres in the colon, which results in the formation of SCFAs such as propionate, butyrate, and acetate. Improved insulin sensitivity and glucose metabolism have been associated with SCFAs.

  • Regulation of Hunger and Weight 

According to some studies, probiotics may have an impact on how the body regulates hunger and helps people lose weight, which can help with glycemic control by lowering insulin resistance.

Types of Probiotics Used for Diabetes Management

  • Fermented Foods

Probiotics are naturally present in fermented foods. Yoghurt, kefir, sauerkraut, kimchi and miso are a few examples. You can enhance your consumption of probiotics by incorporating these foods into your diet.

  • Prebiotic Foods

Prebiotics are fibres that support the good bacteria in your digestive system. Eating foods high in prebiotics, such as whole grains, onions, garlic, leeks, bananas, and asparagus, can help your gut's probiotics develop and function.

  • Functional Foods

Certain foods, such as milk and yoghurt varieties, are fortified with probiotics, making them easy ways to up your probiotic consumption.

Effects of Probiotics Supplements on Glycemic Control

Keep the following considerations in mind while incorporating probiotics into your diet to manage diabetes effectively.

  • Choose Low-Sugar Options

Opt for probiotic-rich foods and supplements that are low in added sugars or are sugar-free to prevent spikes in blood glucose levels.

  • Monitor Portion Sizes

While probiotic-rich foods like yoghurt can be beneficial, be mindful of portion sizes to avoid consuming excessive carbohydrates, especially if they contain added sugars.

  • Balance Your Diet

Incorporate probiotic-rich foods into a well-balanced diet that includes a variety of nutrient-dense foods such as vegetables, fruits, whole grains, lean proteins, and healthy fats to support overall health and glycemic control.

  • Consider Timing

Some people find it helpful to consume probiotic foods or supplements with meals to aid digestion and minimise any potential gastrointestinal discomfort.

  • Monitor Blood Sugar Levels

Keep track of your blood glucose levels regularly, especially when introducing new probiotic foods or supplements.

  • Consult Healthcare Provider

Before starting any new dietary regime or supplement, consult with a healthcare provider to ensure it is safe and appropriate for your needs.

A balanced gut microbiota is important for controlling blood sugar and enhancing insulin sensitivity, and it can be achieved by using probiotics. Additionally, using probiotics may improve immunological response and nutrient absorption, hence promoting general health by preserving a varied microbiota.


  • Do probiotics affect glycemic control?

Supplementation with probiotics has improved glycemic control and lipid profiles in patients with type 2 diabetes.

  • When is the best time to take probiotics?

Generally, the best time of day to take probiotics is with breakfast, or just after.

  • Can I take probiotics every day?

A common question about probiotics is whether it is ok to take probiotic supplements every day. Whilst there may be a few exceptions to this rule, the general answer is yes, it's safe, and usually recommended, to take them daily.
