    The perfect glutamine supplement for muscle growth and increased endurance in your sport!

    Glutamine is the most abundant amino acid found in the body and is also known as a non-essential amino acid. It is used for various functions in human metabolism and is the ultimate amino acid when it comes to repair, recovery and reducing muscle soreness.

    Glutamine is an important fuel source for the cells of the immune system. It can help athletes fight disease and infection because it helps to maintain the health and integrity of the gastrointestinal tract, which is vital to preserve overall well-being. It is also a source of fuel for the cells of the intestines, which improves its function and absorption. Better absorption of nutrients allows an increase in the supply of nutrients to the muscle, promoting their growth.

    Glutamine may become conditionally essential under some circumstances. During intense training the body can lose up to 50% of its glutamine levels making it unable to naturally synthesize enough glutamine to meet its needs. If your immune system or other parts of your body becomes glutamine deficient, the muscles' glutamine stores will be the first ones to be used, which is why it is important to have sufficient levels of glutamine.


    Glutamine 5.0

    Supplementing with Starlabs® GL5 before and immediately after training will enhance your natural level of glutamine and lead to faster muscle recovery. It will also help your immune health and can promote an increase in muscle mass. GL5 mixes easily and is unflavored making it suitable to add to your favorite protein, meal replacement or weight-gainer shake. Taking a serving right before going to bed may also support faster recovery, since it will prevent the body from going into a catabolic state.

    Promotes muscle growth

    · Supports the immune sistem
    · Essential for protein synthesis
    · Helps to repair and rebuild muscle tissue

    Glutamine makes up over 60% of the skeletal muscle tissue. Almost 19% of a glutamine molecule is made up of nitrogen, which makes it the primary conductor of nitrogen to the muscles. Achieving a positive nitrogen balance indicates that your body has adequate protein stores.



    Mix 1 scoop (or 1 rounded teaspoon) with 8 oz (240ml) of water 1-2 times daily.  GL5 can also be added to your favorite protein beverage
