What is the best time to take L citrulline for circulation?
Most people take it 30 to 60 minutes before exercise or on an empty stomach for absorption. Consistent daily use, as directed on the label, supports steady nitric oxide levels. Morning or pre-workout timing works well for most users.
Are there side effects of L citrulline supplements?
L citrulline is generally well-tolerated. Some users may experience mild digestive issues or headaches at high doses. Starting with the recommended serving and staying hydrated can minimize discomfort. For a natural alternative, see our guide on beet root capsules for heart health.
Can L citrulline be taken with other supplements?
