Thrivous publishes Clarity and Alpha Stack formulas openly and completely, and strives to improve the formulas continuously. This contrasts sharply with the practices of many vendors, who hide their product formulas behind proprietary blends.

Open-Source Formulas

Clarity and Alpha Stack has open-source formulas that identify 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 Clarity and Alpha Stack formulas accordingly.
