Pre-workout with caffeine combines stimulants with carbs. The caffeine dose is the primary active ingredient – a meta-analysis (Grgic et al., Br J Sports Med 2020) confirmed 3–6 mg per kg body weight improves exercise performance across all modalities.
How should I track Pre-workout powder, caffeinated?
Pre-workout powder, caffeinated is a good source of magnesium. Supplement tracking comes down to two things: measuring the supplement itself and logging everything around it. For powders like Pre-workout powder, caffeinated, a kitchen scale beats a scoop — scoops typically deliver 10–20% more than the stated serving (Almiron-Roig et al., Appetite 2013, found portion errors of 50–200% for dense foods). For capsules and tablets, count-based tracking is simpler but still matters at multiple daily doses. The real tracking trap is what you mix supplements with — milk, fruit, or nut butter can turn a 30-calorie serving into a 400-calorie shake. Log each ingredient separately for an accurate total.
