- Every Vitablizz article ends with a numbered list of sources, linked to the original paper or guideline.
- We rank evidence: guidelines and systematic reviews first, then randomized trials, then large observational studies.
- We do not use press releases, product websites, social media or AI-generated summaries as sources.
