What’s the go with probiotics?

Probiotics are everywhere, you can’t walk down an isle at the shops without some package saying probiotics!


You will find them added to bars, chews, cereals, drinks and more. But what exactly are they and should we be taking them?

What are probiotics?

Probiotics are living microbes, but they aren’t just any old strain of bacteria or fungus. They are specific strains that have been found to survive the passage all the way down into our upper and lower intestines, and when there, provide us with a health benefit (rather than sitting around doing nothing or causing us harm).

The more species of good bacteria we have in our gut the better! Each different strain of good bacteria or fungus can provide us with some sort of health benefit, so more variety will equal more health benefits.

Their proven benefits

Within the gut, probiotics help to maintain a healthy balance of helpful microbes. This healthy balance is essential to ensure harmful strains don’t overgrow and the gut lining is nourished, healthy, and stays intact.


Probiotics are known to help improve overall digestive health and comfort by minimising symptoms like diarrhoea and irritable bowel syndrome [2].


Their benefits can also extend beyond the gut to other parts of the body. There is evidence that shows their role in supporting immune system function, provide protection against infections, and some can help regulate cholesterol absorption and glucose metabolism [1, 3-5], just to name a few. Probiotics may even play a role in the prevention of inflammatory bowel disease, cardiovascular disease, and diabetes.


Probiotics sound like a magic cure, but not one type of probiotic alone will provide you with all these benefits. Different strains will have differing effects, so it is important to consume several strains for an enhanced effect.

Common probiotic strains and their benefits [1, 6]

Should you be taking them?

It depends.


If you’re someone who eats relatively healthy (i.e. not much processed food, alcohol, sugar, saturated fat, and are eating tonnes of fibre, grains, and veggies) then your gut garden will likely be flourishing with many different varieties of good gut bacteria; therefore, you won’t need to add in a probiotic.


On the other hand, if you don’t eat a variety of vegetables and wholegrains, and consume mostly packaged and processed foods or you have recently been taking a course of antibiotics then your garden will be lacking the varieties that are known to provide us with all those health benefits; therefore, it would be beneficial to add in a broad spectrum probiotic supplement.


BUT


When you start taking a probiotic supplement, you must ensure you eat as much healthy variety as possible to help feed the new strains you are putting in. If you don’t water and fertilise your gut garden the seeds you planted will not grow! Without this nourishment, the probiotics won’t establish themselves and flourish within your gut, which is a waste of money as probiotics can be expensive.


Tips for success

If taking a probiotic supplement, go broad: you want to find a probiotic supplement with as many strains as possible. In addition to this, the more the better. Choose double or even triple strength when you can afford to.

Give the seeds you plant a chance to thrive: Eat plenty of wholegrains, fruits, vegetables, legumes, nuts, and seeds daily. These foods are rich in fibre and plant phytochemicals which will feed all the different types of microbes in your gut allowing them to work at their best to keep you healthy.


Limit excessive amounts of alcohol, sugar, saturated fats, very high amounts of protein, and processed foods. These are known to decrease the diversity of good microbes in the gut which will lead to impaired gut function and other negative health effects.

Some suggested brands:

Life Space – 15 strains

Vivomaxx – 8 strains
