Product Information

📋 Directions for Use

Suggested use: Add 2 scoops to 8 ounces of filtered water, your liquid of choice, or a small amount of food such as organic applesauce. For best results, take first thing in the morning on an empty stomach, or away from food, and sip slowly over 30 minutes. As this is a potent formula, you may consider starting with an initial serving of 1 scoop per day. Do not take within 3 hours of bedtime, as L-glutamine may interfere with sleep. Use as directed by your healthcare professional.
