Question 1

How does L-citrulline differ from citrulline malate?

Accepted Answer

L-citrulline is the pure amino acid, while citrulline malate is a combination of citrulline and malic acid (malate) in a 2:1 ratio. The malate component supports energy production in the Krebs cycle. Citrulline malate is often recommended for training performance, but pure citrulline provides a stronger NO-boosting effect gram for gram.

Question 2

How much L-citrulline should I take before training?

Accepted Answer

For pure L-citrulline, 3-6 grams is recommended 30-60 minutes before training. For citrulline malate, the effective dose is 6-8 grams (containing about 4-5 grams of pure citrulline). For best results, take citrulline consistently every day, not only on training days.

Question 3

Can L-citrulline be combined with other pre-workout supplements?

Accepted Answer

Yes, citrulline pairs excellently with other pre-workout supplements. Popular combinations include citrulline + beta-alanine for endurance, citrulline + caffeine for energy, and citrulline + creatine for strength. Many pre-workout products already contain citrulline, so check ingredients to avoid double-dosing.

Question 4

Does L-citrulline have side effects?

Accepted Answer

L-citrulline is generally very well tolerated. Rare side effects may include mild stomach discomfort or digestive upset, especially with larger doses on an empty stomach. Those taking blood pressure medications should consult their doctor, as citrulline may slightly lower blood pressure. No other significant side effects have been found in research.
