Natural pre-workout: boost your workout without chemical stimulants

In the world of bodybuilding and fitness, “pre-workout” supplements have become commonplace. Many contain high doses of caffeine, which are sometimes poorly tolerated. There are also natural ingredients that have been studied for their ability to support energy levels during training. Here is an overview.

What is the purpose of a pre-workout?

• Increase physical and mental energy
• Stimulate vasodilation (muscle pump)
• Delay the sensation of muscle fatigue
• Improve focus

Natural ingredients often studied

Citrulline malate

• Studied for its effect on blood flow and muscle pump [1]
• Studied dose: 6 to 8 g before exercise

Beta-alanine

• Increases muscle carnosine levels, delaying muscle acidification [2]
• Studied dose: 2 to 4 g/day

L-Tyrosine

• Precursor to dopamine and noradrenaline, studied for mental focus [6]

Adaptogenic plant extracts

• Ginseng, Rhodiola rosea, Ashwagandha: studied for their effect on physical stress resistance [7]

When and how should it be taken?

• Consume 20 to 30 minutes before the session
• Stay sufficiently hydrated before and during exercise

Possible side effects

• Beta-alanine can cause temporary tingling (paresthesia), which is not known to be serious
• Read labels carefully; if in doubt, seek medical advice

Note: our pre-workouts currently in our catalog contain caffeine (unlike the "stimulant-free" approach presented above). If you are sensitive to caffeine, check the ingredients list before purchasing.

• C4 Original Pre-Workout Liquid Shot (Cellucor) — contains caffeine
• Vapor X5 Pre-Workout, Creatine & Caffeine (MuscleTech) — contains caffeine

Conclusion

Several natural ingredients (citrulline, beta-alanine, tyrosine, adaptogens) are studied for supporting training energy without necessarily resorting to high doses of caffeine.
