Price per effective dose calculator
Compare supplements by useful active amount, not package price alone.
Enter the values above to see the decision math.
Use this as a value screen only. It does not prove effectiveness, purity, or clinical fit.
How to interpret the result
The lowest bottle price is not always the lowest useful cost. A product with more active ingredient per serving may cost more upfront but less per meaningful amount.
Use the calculator as a value screen only. Then check form, tolerability, third-party testing, ingredient evidence, and interaction cautions before treating the cheapest option as the best option.
