What they cover for Good Decades
Medical review of clinical claims across sleep, metabolic topics, and women's health. Every article she reviews carries her name and the review date.
An internist with fifteen years of clinical practice, Dr. Álvarez reviews Good Decades’ clinical content to ensure every claim is traceable to evidence and that the site says plainly when a topic needs medical attention rather than an article.
Her review rule: if a paragraph could delay a needed appointment, it gets rewritten.
Conflicts of interest
Dr. Álvarez is paid by Good Decades for medical review. She holds no positions in, and receives no payments from, any supplement, device, or pharmaceutical company mentioned on this site.
