When it comes to gut health, probiotics often steal the spotlight - but prebiotics are just as important.
While probiotics are live bacteria that support a healthy microbiome, prebiotics are the fuel that helps those good bacteria thrive. Think of them as fertiliser for your gut, feeding beneficial microbes and promoting better digestion, immunity and even mood regulation.
Prebiotic powders are an easy way to increase your intake of these gut-friendly fibres, but choosing the right one can be tricky. The most common types include inulin, fructooligosaccharides (FOS), and galactooligosaccharides (GOS) - all of which naturally occur in foods like chicory root, bananas and onions. Different types of prebiotics nourish different strains of gut bacteria, so opting for a blend can be particularly effective.
One key factor to consider is digestibility. While prebiotics are meant to be fermented by gut bacteria, some people find certain fibres cause bloating or discomfort. If you have a sensitive stomach, look for a low-FODMAP option or start with a small dose to see how your body responds.
You’ll also want to check the ingredients list. Some prebiotic powders come with added probiotics for a two-in-one gut health boost, while others include extra nutrients like polyphenols, which further support microbial diversity. Avoid products with unnecessary fillers or artificial sweeteners, as these can negate the benefits.
Whether you’re looking to improve digestion, support immunity or simply give your gut bacteria the nourishment they need, a high-quality prebiotic powder can make a real difference: the key is finding one that works for your body.
