Low-FODMAP Diets and Supplements for Athletes with Digestive Sensitivities

August 29, 2022 | Supplements and Nutrition

For athletes with digestive sensitivities or irritable bowel syndrome (IBS), finding the right supplements can be challenging, as many products may trigger uncomfortable symptoms. One approach to managing these sensitivities is to follow a low-FODMAP diet, which restricts specific types of carbohydrates known to cause digestive issues. Here, we discuss low-FODMAP supplements that can support your athletic performance while being gentle on your gut:

  1. Low-FODMAP Protein Powders: Protein powders are a popular supplement among athletes, but many options contain high-FODMAP ingredients like whey protein concentrate or added sweeteners. Instead, look for a low-FODMAP protein powder made from rice, pea, or hemp protein, or a whey protein isolate, which contains less lactose. Avoid protein powders with added sugars or sugar alcohols, as these can also be high-FODMAP.
  2. Low-FODMAP Electrolytes: Electrolyte supplements are essential for maintaining hydration and preventing muscle cramps, particularly during endurance events or in hot climates. Many electrolyte supplements contain high-FODMAP sweeteners like fructose or sugar alcohols. Opt for a low-FODMAP electrolyte supplement free from these additives, or consider making your own by combining water, salt, and a squeeze of lemon or lime juice.
  3. Low-FODMAP Prebiotics: Prebiotics are non-digestible fibers that feed the beneficial bacteria in your gut, promoting a healthy microbiome. However, many prebiotic supplements are high-FODMAP, as they contain ingredients like inulin or fructooligosaccharides (FOS). Instead, look for a low-FODMAP prebiotic supplement containing partially hydrolyzed guar gum (PHGG) or lactulose.
  4. Low-FODMAP BCAAs: Branched-chain amino acids (BCAAs) are popular among athletes for their role in muscle recovery and growth. While many BCAA supplements are low-FODMAP, be cautious of products with added sweeteners or flavorings that may trigger symptoms. Choose a BCAA supplement with a 2:1:1 ratio of leucine to isoleucine and valine, and opt for unflavored or naturally sweetened options.
  5. Low-FODMAP Multivitamins: A high-quality multivitamin can help athletes with digestive sensitivities meet their micronutrient needs. Look for a low-FODMAP multivitamin without added sugars, artificial sweeteners, or high-FODMAP fibers like inulin. Ensure the multivitamin contains essential nutrients like B vitamins, magnesium, and zinc, which can be particularly important for athletes.
  6. Low-FODMAP Collagen: Collagen supplements have gained popularity for their potential benefits in joint health, skin elasticity, and muscle recovery. Many collagen supplements are low-FODMAP, as they are derived from animal sources and typically don’t contain added sugars or fibers. Opt for a pure, unflavored collagen supplement or one with natural, low-FODMAP flavorings and sweeteners.
  7. Low-FODMAP Creatine: Creatine is a well-researched supplement that can help improve athletic performance, particularly in high-intensity or short-duration activities. Most creatine supplements are low-FODMAP, as they consist of pure creatine monohydrate without added ingredients. Stick to unflavored creatine or options with low-FODMAP sweeteners and flavorings to avoid triggering symptoms.
  8. Low-FODMAP Omega-3s: Omega-3 fatty acids are essential for heart health, brain function, and reducing inflammation, making them particularly beneficial for athletes. Fish oil supplements are typically low-FODMAP, as they don’t contain carbohydrates or sugars. Choose a high-quality fish oil supplement with a high concentration of EPA and DHA, and opt for options without added flavorings or sweeteners.
  9. Low-FODMAP Probiotics: Probiotics can help support gut health and immune function in athletes with digestive sensitivities. However, some probiotic supplements contain high-FODMAP prebiotic fibers or additives. Look for a low-FODMAP probiotic supplement without added sugars or fibers, and opt for a product with well-researched strains like Lactobacillus and Bifidobacterium.
  10. Low-FODMAP Vitamin D: Vitamin D is essential for bone health, immune function, and muscle function, making it an important nutrient for athletes. Many vitamin D supplements are low-FODMAP, as they are derived from animal or plant sources and don’t contain added sugars or fibers. Choose a vitamin D3 supplement, as it is more bioavailable than vitamin D2, and opt for options without added flavorings or sweeteners.

In conclusion, athletes with digestive sensitivities or IBS can still benefit from a wide range of supplements by choosing low-FODMAP options. Always consult with a healthcare professional before starting any new supplement regimen, and consider working with a dietitian experienced in the low-FODMAP diet to ensure you’re meeting your individual nutritional needs.
