Growth hormone helps to maintain youthful protein synthesis within cells. Arginine's primary anti-aging effect is to promote growth hormone release and enhance protein synthesis throughout the body. The age-related decline in immune function can be partially corrected by enhancing growth hormone release. If you are going to use arginine to boost growth hormone levels, you should take 5-15 grams at bedtime on an empty stomach or before exercise. If you are taking arginine for reasons other than for promoting growth hormone release, you can take it any time of the day, preferably on an empty stomach.
