Hi im on sertraline 100mg a day and want to start taking raspberry keytones how long would you recommend using the keytones for thank you?

Your choice: Raspberry ketone is said to reduce appetite & increase metabolism, thus causing weight loss. This should have no interaction with the Zoloft that you are taking. Zoloft itself may normalize appetite through its serotonin-increasing effect, but does nothing specifically for weight gain or weight loss. Any effect seen there would be as a byproduct of it's managing depression symptoms.
