What are amino acids?

What are amino acids

Amino acids are large molecules that used as building blocks to create proteins. They can be strung together into chains, folded into 3D structures or even have interlinking connections to develop the many protein structures in our cells and tissues. There are twenty different types of amino acids, each with a slightly different structure, making them ideal for various proteins and body processes.

Some amino acids are known as 'non-essential' because you can produce them through a series of chemical reactions in your cells. Others are 'essential' because you need to get them through your diet.

Some amino acid supplements come with the prefix 'L' like 'L-Glutamine'. This is because they all come in a left (L) and a right (D for Dexer) version. Both types are nearly identical, but their structure is the mirror image of each other. For example, your left hand appears as if it is the reflection of your right. It's the same with amino acids, the basic structure is the same, but everything is the other way round. You'll most likely find products containing 'L' amino acids because they're considered slightly more stable and may be favoured in some bodily functions.

Benefits of amino acids

Benefits of amino acids

All twenty amino acids are needed throughout the body, but single types can be taken as supplements because of their benefits to specific organs or body parts. People are most likely to use essential amino acids to supplement their diet, but we also stock full-spectrum amino acids for when your body may need more complete support.

Amino acids are taken for a range of different reasons:

Sport and exercise – They can be used in muscle repair and to create energy in your cells. That makes them ideal for aiding recovery after exercise. We've chosen G&G Vitamin's Full Spectrum Amino Acids to provide comprehensive support for people who like to get active or regularly enjoy a range of sports.

Healthy skin and hair – Your skin and hair rely on amino acids for many different structures and daily processes. If you supply a reliable source of the necessary amino acids, your hair is able to grow effectively and your skin can repair any damaged areas. Another research study also discovered that some hair loss is linked to the deficiency of some amino acids. L-Cysteine is used to promote healthy skin and hair.

Gut health and digestion – Some amino acids play a role in regulating your gut's health and protecting its wall. Studies have found that glutamine is a vital part of a healthy gut and that supplementation may be useful if glutamine levels have become depleted.

Improved sleep quality – Tryptophan is used in processes that produce the sleep hormone melatonin. Consequently, it's often taken by people who want to improve their sleep-wake cycle. We stock Night Aid from G&G vitamins because it provides comprehensive support for healthy sleep, including 5-HTP, which becomes tryptophan when metabolised.
