Why do Previnex supplements come in a 4-week supply?

When Previnex was founded, we worked very closely with physicians, and in clinical and medical settings, a 4-week supply is the standard dosing cycle. This approach ensures consistency, precision, and adherence to a complete regimen, and this is why our supplements come in a 4-week supply versus a calendar month supply (30-day). 

As Previnex has grown significantly outside of the medical setting, we are actively evaluating whether future packaging should align with calendar-based subscription cycles (3- day), while remaining true to our science-first and clinical philosophies.
