Science & safety
Decade is a wellness concierge built to help you choose supplements with confidence. Here's how we make sure every recommendation and every product is worth trusting.
Evidence-led recommendations
Every protocol Decade suggests is anchored to peer-reviewed clinical literature. We publish the references on each plan.
Medical team review
A board-certified functional medicine clinician reviews the model's protocols weekly and adjusts the system prompt when evidence changes.
Third-party tested products
Every product on Decade ships with an independent lab COA: heavy metals, microbials, label accuracy. No proprietary blends.
Red-flag escalation
If you describe symptoms that need a real clinic (chest pain, suicidal ideation, severe weight loss), Decade stops and points you to one.
No diagnosis, no Rx
Decade will never claim to diagnose a disease, prescribe a drug, or replace your physician. It's a supplement concierge with good manners.
Your data, yours
Encrypted at rest and in transit. Never sold. Exportable and deletable on demand. Your chat history is yours.
A note from our medical director
"The best supplement plan is the one you actually follow. Decade's job is to make the consistent, evidence-based stuff easy enough that you keep doing it. Ten years of small, correct decisions is the whole game."
Dr. M. Chen, MD · Decade Medical Director
