Common questions

Combining supplements

Updated: October 25, 2026

Yes, the core supplements go together:

  • Protein + creatine — fine in one shake.
  • Pre-workout + creatine — many pre-workouts already contain creatine, add up the dose.
  • Multivitamin + omega-3 — together with food.

Watch out:

  • Caffeine — pre-workout, fat burner, energy drinks and coffee together: no more than 400 mg a day.
  • Vitamins and minerals — don't double up from several products.
  • Take iron, calcium and zinc separately.

Add new supplements one at a time so you know what each one does.
