How our review process works
Education and formula pages are drafted by our team, then reviewed by the relevant advisor before publishing. We favor cautious, supports-style language and avoid disease claims. When new evidence emerges, pages are updated and the change is noted. Our advisors guide our standards; they are not a substitute for your own healthcare professional, and nothing here is personal medical advice.
Want to see how this rigor shows up in the product itself? The quality standards page covers testing, and the verification page lets you check the current batch.
