Why Cofactor
Protocol-specific formulas
Supplements formulated for your exact medication — GLP-1, TRT, HRT, Metformin, PPI, or Statin. Not generic multivitamins.
Evidence-informed formulas
Every ingredient addresses a documented nutritional concern for your specific protocol. Built on published research, not trends.
Third-party tested
Every batch is tested for purity, potency, and quality you can trust.
Daily support, not a medication
Dietary supplements designed as daily companions to your protocol. Not intended to treat, cure, or prevent any disease.
What supplements should I take with my GLP-1, TRT, or other medication?
Each protocol depletes different nutrients. Cofactor products are formulated for your specific medication — select your protocol above to find the right match.
Are Cofactor supplements safe to take with Ozempic, testosterone therapy, or metformin?
Our formulas are designed to complement — not interfere with — your prescribed protocol. We recommend consulting your healthcare provider before starting any supplement.
How is Cofactor different from a regular multivitamin?
Generic multivitamins aren't formulated for the specific nutrient depletions your medication causes. Each Cofactor product targets the documented nutritional gaps of your exact protocol.
