The recommended daily intake of CFUs (colony-forming units) for probiotics varies depending on the individual's health goals and conditions. Generally, for maintaining digestive health and supporting the immune system, doses can range from 1 billion to 10 billion CFUs per day. For specific health issues, higher doses may be recommended, sometimes up to 20 billion CFUs or more. It's important to consult with a healthcare provider to determine the most appropriate dose based on personal health needs and the specific strains of probiotics being used.
