Guides

Start with the question, not the product pitch. These guides explain supplement use, ingredient evidence, marketing claims and practical decisions without turning every question into a sales pitch. Firsthand observations are distinguished from research where relevant. For each guide, check whether the evidence concerns a finished product, a single ingredient, or an uncontrolled personal account; these are not interchangeable. Verify current labels and buying terms before purchasing.
