Abstract: To help consumers around the world reduce the confusion and complexity of choosing among thousands of wellness products that are effective for their particular medical conditions and/or wellness goals, the present inventor, devised one or more exemplary systems, methods, software, and data structures for recommending products, such as health, fitness, and nutritional products, to consumers. One exemplary system receives user profile information, such as gender, age, medical condition(s), wellness goal(s), biometric data, allergies and sensitivities, and/or nutrition information, and recommends products based on the consumer profiles and product ingredient efficacy and/or contraindications for the medical conditions and/or wellness goals. The system recommends the most scientifically effective products for a particular consumer, while accounting for contraindications thereby reducing risk potentially harmful products.
