1. Probiotics – The Foundation of Gut HealthProbiotics are live bacteria and yeasts that help balance the gut microbiome. They replenish good bacteria, support digestion, and may even boost immunity. Strains like Lactobacillus and Bifidobacterium are particularly effective. Look for high-quality, multi-strain probiotics with at least 10 billion CFUs (colony-forming units) per serving.

2. Prebiotics – Fuel for Good BacteriaProbiotics are only part of the equation—prebiotics are just as important. These indigestible fibers serve as food for beneficial gut bacteria, helping them thrive. Sources include inulin, chicory root, and resistant starch. Taking a prebiotic supplement can significantly enhance the effectiveness of probiotics.

3. L-Glutamine – Repair and Strengthen the Gut LiningL-Glutamine is an amino acid that helps maintain and repair the intestinal lining. It’s particularly useful for those suffering from leaky gut syndrome, irritable bowel syndrome (IBS), or inflammation. By strengthening the gut barrier, it helps prevent toxins from entering the bloodstream and supports overall gut integrity.

4. Digestive Enzymes – Enhance Nutrient AbsorptionDigestive enzymes help break down proteins, fats, and carbohydrates, making it easier for the body to absorb nutrients. If you often experience bloating, gas, or indigestion, a digestive enzyme supplement can be a game-changer. Look for blends that include protease, amylase, and lipase to cover all macronutrients.

5. Butyrate – The Underrated Gut Health BoosterButyrate is a short-chain fatty acid that promotes gut lining health and reduces inflammation. It’s produced naturally when gut bacteria ferment fiber, but supplementation can be helpful for those with gut issues like IBS or inflammatory bowel disease (IBD). Butyrate supports gut barrier function and helps regulate the immune response in the digestive tract.
