Jules Miller, one of The Nue Co’s co-founders, has irritable bowel syndrome (IBS), so it’s hardly surprising that the brand knows its stuff when it comes to gut health. Culturelle is a well-known brand of probiotics and is one of the best overall probiotic supplements thanks to its formulation and high CFU count. What’s more, it’s NSF Certified for Sport, meaning it has been tested to ensure that it’s free of substances that are banned for competitive athletes.

Intended use: The effectiveness of probiotic supplements is not only strain-specific but also disease-specific, meaning the correct strain and dose must be appropriate for the condition or symptom you intend to treat. Symprove has become one of the most widely known and most renowned supplements that delivers live, active multi-strain bacteria to the gut. Far from being a cheap probiotic powder, Custom Probiotics’ 11-Strain Custom Probiotic Powder is a true, high-quality performer. Some of the core, food-based components of this mix include green bananas, acacia, and Jerusalem artichokes.Thanks to the inclusion of these two specific strains and prebiotics — which can provide fuel for the beneficial bacteria in the digestive tract — this is one of the best probiotics available for maintaining overall gut health. Drink with hot water, add to salads, mix into smoothies or put those partying skills to good use and shot it neat. Developed in consultation with Healthspan's expert panel of nutritionists and scientists, all our Elite products are batch-tested and approved by Informed Sport to be safer for competing athletes, with optimal doses for those competing at the highest level.

The flavor is fantastic, the ingredients and creation process are clear on Ritual’s site, and it’s truly an all-encompassing gut health solution in my opinion. In a double-blind placebo trial, they were shown to improve abdominal pain, gas, constipation, diarrhoea and bloating. Note that the dosage recommendations vary between 1 and 2 capsules or tablets, taken 1–2 times daily. If you’re interested in taking a probiotic supplement, it’s important to first determine whether a probiotic supplement is necessary for your specific health needs.Simply mix a 15g serving of Biomel complete gut powder with your usual milk – we used almond milk – for a delicious shake that contains 25 billion probiotic cultures from 13 different strains, prebiotic fibres, digestive enzymes, and vitamins and minerals such as vitamins B6, B12 and D and calcium. Vitamins B6 and D3 contribute to the reduction of tiredness and fatigue, and to the normal function of the immune system. Digestive enzymes are added to the mix to aid in nutrient absorption and reduce gas, bloating and indigestion.
