Boosting immunity with probiotics: What the research says

25th May 2025

When it comes to health, and in particular our gut health, the word ‘probiotics’ is one that we are beginning to hear more and more. Scientists and nutritionists are keen to communicate the connection between our gut and our overall wellbeing, and by introducing probiotics into our diet, we can begin to embrace a much healthier lifestyle.

Probiotic consumption helps increase the volume of good bacteria in our gut, combating the likes of pathogens and harmful bacteria and enabling our immune system to flourish.

There is a clear connection between high levels of harmful bacteria and the likelihood of developing sickness bugs and infections, which is just one of the many reasons why it’s so vital that we take great care of our gut microbiota. The good news is that we can improve our gut health easily by simply adjusting our diet and introducing probiotic-rich foods. At Dr. Ohhira, we specialise in probiotic supplements, making it easier than ever to enhance our gut health and embrace a healthier lifestyle overall.

How probiotics support our body’s natural immunity: 4 ways probiotics boost our immune system

  1. Probiotics help strengthen our gut barrier
    Did you know that around 70-80% of our immunity comes directly from our gut? Probiotics support this by strengthening our gut lining, ultimately preventing harmful bacteria and pathogens from entering into our bloodstream.
  2. Probiotics help balance our gut microbiome
    Maintaining a healthy microbiome is essential to our health. A good microbiota works to prevent the growth of potentially harmful bacteria, all whilst enhancing immune cell function and improving our body’s ability to respond to the threat of infection.
  3. Probiotics effectively stimulate our immune cells
    Some probiotic strains have been proven to effectively elevate the activity of infection-fighting cells, optimising our immunity and fending off harmful bacteria and pathogens.
  4. Probiotics have been proven to reduce harmful inflammation
    The term ‘inflammation’ is one that we often hear when discussing gut health, and that’s because inflammation in the gut is incredibly harmful to our wellbeing. Fortunately, there are certain probiotic strains that effectively minimise inflammation, reducing the risk of infection, disease and even certain allergic reactions.

What are the best probiotics for immunity?

There are lots of different probiotic supplements available to buy, which can make the process confusing. The important thing to remember is that different strains of probiotics do different things. If you are specifically looking for a probiotic supplement that will help support your body’s natural immunity and defences, then we would recommend looking at multi-strain formulas.

Multi-strain probiotics are likely to offer a wider spectrum of immune-boosting benefits, allowing your gut to thrive and leading to improved overall health and wellbeing.
