Abstract: A method for detecting and affirming intent to consume a supplement includes: at a wearable device worn on a hand of a user, broadcasting a wireless interrogation signal; and receiving an inbound wireless identifier responsive to the wireless interrogation signal. The method also includes, in response to the inbound wireless identifier matching a tag identifier linked to a supplement in a user profile associated with the user: detecting proximity of the supplement to the user; predicting intent of the user to consume a dose of the supplement; retrieving a consumption window for the supplement from a supplement regimen in the user account; and. in response to the current time falling outside of the consumption window, vibrating the wearable device according to a second vibration pattern during a haptic consumption avoidance cycle to prompt the user to delay consumption of the supplement.
