Function Health discount code

How to use the HUBERMAN code

1. Start a Function Health membership and continue to checkout.
2. Open the promo-code field in the order summary.
3. Enter HUBERMAN and apply it.
4. Confirm that the first-year total falls from $365 to $315 before paying.

Function accepts one promo code per order. The discount applies to the first year; the membership renews at the regular price unless Function shows different renewal terms at checkout.

Other Function Health codes

Codes such as EXCELLENCE25, member referral links, and partner promotions also circulate, but I have not personally verified them in August 2026. EXCELLENCE25 has historically offered $25 off, which is worse than HUBERMAN when both work. Referral and partner offers change, so compare the final checkout total rather than relying on an advertised code.

The expired Function Day and Chase Sapphire Reserve promotions are not current promo codes. If another card-linked Function offer appears in your Chase, Amex, or Capital One account, it may apply separately when you use that card. See the historical Function Health Chase offer for how that type of promotion worked.

Is $315 a good price for Function Health?

At $315, Function Health remains more expensive than Superpower at $199, but Function includes a broad initial panel and a narrower mid-year retest. The discount is most useful if you have already decided that Function's repeat testing and app are worth paying for.

If price is the deciding factor, compare the services before checking out. Our Function Health vs Superpower guide explains what the extra cost buys, while the Function Health cost guide covers HSA/FSA payment and lower-cost alternatives.
