How we create, verify, and maintain the integrity of every piece of content
All content is written by Dr. Marcus Holloway, a Certified Nutritional Specialist with a Master of Science in Human Nutrition from the University of Texas at Austin. No content is outsourced to anonymous writers or AI-only generators. Every review and analysis is the product of direct clinical research.
Every health claim must be supported by at least one peer-reviewed publication. Our preferred sources:
Manufacturer press releases and non-peer-reviewed sources are never used as primary evidence for health claims.
Products are selected based on: relevance to our readers' health concerns, availability through established retail channels, quality of clinical evidence for key ingredients, and manufacturer transparency about formula composition and manufacturing standards. We do not accept payment to review products.
All reviews are fully updated at minimum annually. Earlier updates are triggered by: new clinical evidence, formula changes, pricing changes, or reader-reported inaccuracies. Publication and update dates appear on every content page.
If a reader identifies an error, we review the claim within 5 business days and correct it promptly if confirmed. To report an error: contact@prostepeak.com
