An NIH record form and FDA information about dietary-supplement regulation
The NIH Office of Dietary Supplements publishes a consumer fact sheet on dietary supplements. Its text includes a link to a printable form titled "My Dietary Supplement and Medicine Record." The fact sheet does not evaluate MB Dose Log.
The FDA explains that dietary supplements are not approved for safety and effectiveness before they are sold. That general explanation does not establish the regulatory category or status of an individual methylene blue product.
This page provides a descriptive summary of the cited sources, not medical advice, dosing guidance, or instructions for product use or medical action. Source citations do not imply endorsement of MB Dose Log.
