Frequently Asked Questions

Q: How long before my workout should I take an energy supplement or pre-workout?

A: For powder pre-workouts and caffeine capsules, consume them 15–30 minutes before exercise so the active ingredients kick in right as your session starts. Ready-to-drink cans can be sipped 15 minutes before or during light activity.

Q: Will energy supplements make me feel jittery or crash afterwards?

A: It depends on the caffeine dosage and your tolerance. If you are sensitive to stimulants, start with a half-serving or opt for lower-caffeine ready-to-drink options rather than high-strength pre-workout powders.
