Surge has an open-source formula that identifies all ingredients and their dosages. This is the only way to know what and how much you are using, which is essential to good decisions.

Continuous Improvement

Because science is never finished, we continuously monitor and review new studies, consult with our advisor board of physicians and scientists, and update the Surge formula accordingly.
