Buying Guide: What to Look for in a Men’s Probiotic
CFU Strength: How Many Billion Live Cultures?
CFU stands for colony-forming units, essentially the number of live bacteria in each dose. For daily men’s probiotic, 30 to 50 billion CFUs is a common range. This amount helps ensure enough bacteria survive stomach acid to reach your intestines.
Nature’s Way Fortify offers both 30 billion and 50 billion options, so you can choose based on your comfort level and specific needs. If you’re new to probiotics, starting with a lower CFU count might be gentler on your system.
Strain Diversity: The Role of Multiple Probiotic Strains
Different probiotic strains target different aspects of gut health. A diverse blend of Lactobacillus and Bifidobacterium species can support digestion, regularity, and immune function. Look for strains backed by clinical evidence, such as B. lactis HN019, which is often preferred for regularity.
Nature’s Way Fortify formulas typically include 10 to 11 diverse strains, with some containing the doctor-preferred strain for regularity. This variety helps ensure you’re addressing multiple facets of your digestive wellbeing. Comparing different strain profiles can help you decide, as we did in our review of Pure Encapsulations Probiotic 50B.
Prebiotics: Fuel for Your Good Bacteria
Prebiotics are non-digestible fibers that serve as food for probiotics. Including prebiotics in your supplement can enhance the survival and colonization of beneficial bacteria. Many Nature’s Way Fortify products include plant-based prebiotic fiber, which is a convenient way to get both pre- and probiotics in one capsule.
If you’re also exploring other digestive enzymes, understanding how prebiotics work alongside probiotics is crucial. Check out our guide on how digestive enzymes work to see how they complement each other.
Targeted Formulas: Daily, Extra Strength, and 50+
Nature’s Way Fortify offers specialized versions, such as a daily maintenance formula, an extra-strength option with higher CFUs, and a blend designed for adults over 50. Choose a formula that aligns with your age, lifestyle, and digestive concerns. For men over 50, the Fortify 30 Billion Daily may be an excellent choice, as it includes clinically studied strains for colon health. If you’re new to digestive supplements, you may also want to understand the benefits of digestive enzymes, which can complement probiotics.
On the other hand, if you’re looking for maximum digestive support, the extra-strength version with 50 billion CFUs might be more suitable. Always consider your individual tolerance and health goals.
