This essential amino acid is a big part of your workout – over 60% of your muscles are made of it. Black Diamond Supplements is ready to help keep your fitness regimen effective, with a full selection of L-Glutamine products.

During heavy workouts, L-Glutamine is depleted at high rates, affecting your body during and after your gym time. Use this supplement to ensure that your workouts don’t slow down by taking them before you begin. Use one of our quality formulations after your sessions to ensure that this amino acid is available to help repair muscle damage and assist in recovery.

Black Diamond Supplements helps you simplify your supplement stacks with powders to add to your favorite protein drink or beverage, or capsules. Whatever your preference, you’ll be tapping into the power of L-Glutamine – used by athletes in search of boosting their immune system, intestinal health, and muscle metabolism.

When you’re increasing the frequency and intensity of your workouts, don’t let your L-Glutamine levels dip. During times of stress, your body may lose its ability to replace this amino acid’s loss as needed. Adding this hard-working building block to your overall mass protein intake keeps your performance strong and your body ready for maximum recovery intra-workout.
