Grade your supplement stack.

Add what you actually take, pick what you’re optimizing for, and get a letter grade — goal coverage, drug-supplement interactions, and the double-dosing most people never catch. Built on the Sage + Stone Stack Score.

What are you optimizing for?

Pick up to a few. This is how we score whether your stack actually covers your goals.

Taking any of these?

Optional — but it lets us check for the drug-supplement interactions that matter most. We don't store this.

What we found

Sage + Stone surfaces insights, not medical advice. This grade is educational and based on the supplements you entered, not your blood work or full history. Talk to your clinician before changing any supplement or medication — especially anything flagged as an interaction. These statements have not been evaluated by the Food and Drug Administration; this is not intended to diagnose, treat, cure, or prevent any disease.

We'll email your personalized fix-it list — and your early invite to Sage + Stone, where your exact products and doses get graded on efficacy and price too.
