Wiki – a knowledge base of materials on various aspects of nutrition in sports and training. Here, you will find scientific reviews of different types of sports nutrition, diets, and workouts, including their benefits, effectiveness, and potential health risks. When writing articles, we strive to avoid speculation (where possible) and rely exclusively on scientific facts and expert opinions from scientists and doctors.
For the most popular types of sports supplements, the information we have is summarized on dedicated pages that include:
- Ratings of benefits and effectiveness for muscle gain, weight loss, and health risks – our assessment based on available data;
- A list of knowledge base articles about the specific supplement, featuring the most important and interesting facts from scientific studies;
- Data from our own experiments on effectiveness (for safe types of sports supplements) (coming soon);
- Laboratory quality tests (coming soon);
- Surveys (coming soon).
We make every effort to provide comprehensive and complete information based on multiple factors rather than a single subjective opinion of a seller, professional, or anyone else.
