Arginine, an amino acid, is not directly linked to causing wakefulness or insomnia. However, it does play a role in synthesizing nitric oxide, which can improve circulation. For some, an increase in blood flow might lead to a feeling of more energy, but it's unlikely to directly keep you awake. If you're sensitive to changes in your body's energy levels at night, consider taking arginine in the morning or early afternoon to avoid any potential impact on your sleep.

- When is the best time to take arginine to avoid sleep disruption? Taking arginine in the morning or early afternoon is recommended to minimize any potential impact on nighttime sleep, especially for those sensitive to its energizing effects.
