The Pre Workout Trio You Should Know: Caffeine, Beta Alanine and Citrulline

Pre workout formulas are not random magic dust. There are three powerhouse ingredients that make most of the energy, pump and focus effects happen in your scoop.

If you have ever felt that skin tingling sensation before a set… or that powerful pump halfway through your workout… you have already met them.

Let’s break down what they do and why they matter.

Caffeine

What It Is:
A central nervous system stimulant that increases alertness, mental focus and overall energy.

Why It Matters:
Caffeine blocks adenosine (the chemical that signals tiredness) and increases dopamine and norepinephrine levels. This supports faster reaction time, better training intensity, improved mood and stronger endurance.

Typical Dose: 150 to 300 mg in most pre workouts
Half life is about 3 to 6 hours so earlier in the day is better for sleep.

Beta Alanine

What It Is:
A non essential amino acid that increases muscle carnosine levels.

Why It Matters:
Beta alanine helps buffer lactic acid. This delays fatigue, especially during sets in the 60 to 120 second range which is common for hypertrophy style training. The tingling sensation you sometimes feel is normal and harmless.

Effective Dose: 3.2 to 6.4 g daily
Consistency matters since carnosine builds over time.

Citrulline (or Citrulline Malate)

What It Is:
An amino acid used to boost nitric oxide and increase blood flow.

Why It Matters:
Citrulline supports vasodilation which improves nutrient delivery, muscle pumps, endurance and performance. Citrulline malate also helps reduce fatigue and supports energy production.

Clinical Dose: 6 to 8 g citrulline malate, or 3 to 5 g pure L citrulline

Why They Work So Well Together

When these three are stacked together you get:

  • caffeine for energy and focus

  • beta alanine for endurance

  • citrulline for pump and blood flow

Mind. Muscle. Movement.
Better training sessions mean better progress over time.

Final Thoughts
