Why choose L-Glutamine?

L-Glutamine is a non-essential amino acid. Non-essential amino acids can be produced naturally by the body from other amino acids however under circumstances such as times of stress or illness, the body may not be able to produce as much l-Glutamine as is required. This is when supplementation can be useful.  

L-Glutamine is involved in numerous metabolic processes within the body. Our muscles use l-Glutamine as an important source of fuel for muscle contraction. This is why many personal trainers recommend taking a supplemental form of l-Glutamine either pre or post training to ensure that l-Glutamine levels are not depleted, thereby aiding the natural recovery of muscles post exercise.

The cells of the gastrointestinal tract lining are one of the biggest users of l-Glutamine, using it as a source of energy for building and functioning properly. L-Glutamine is often used by those requiring support for a healthy gut lining. 

L-Glutamine is a prescursor to glutathione, often known as the "master antioxidant" - an incredibly powerful molecule that is able to recycle other antioxidants, as well as protect cells from oxidative damage.

This product provides 500mg of this important amino acid in each capsule, allowing easy and flexible dosing. The dosage can be increased or decreased as desired. 

What are amino acids?

Amino acids are compounds that form poylpeptides and ultimately, proteins, which are needed for the structure, function and regulation of our body's cells, tissues and organs. Amino acids are often referred to as the "building blocks of protein" and consequently play a vital role in the body. Amino acids can be essential, meaning that they cannot be made in the body and have to be consumed as part of the diet; or non-essential, meaning they can be made within the body. However, some amino acids cannot be made quickly enough in the body in certain circumstances such as during periods of physiological stress, and these amino acids are termed "conditionally essential amino acids", of which l-Glutamine is one. 

Can the capsules be split open?

Yes, the capsules can easily be split open and added to your usual shakes and drinks if desired.
