We focus on three amino acids which are essential to good health and well-being.

Amino acids are vital for building and rebuilding muscle. Yet, they can do far more, as they contribute to human health in many ways that people don’t realise. Three amino acids, L-Arginine, L-Lysine and L-Citrulline, all contribute to the body in a myriad of ways. In this article we will explore how these three amino acids can be used to address a range of health issues.


The body converts L-Arginine into nitric oxide. Nitric oxide is important because it causes blood vessels to open up wider, resulting in greater blood fl ow. Frequently, L-Arginine is used to treat issues related to heart disease such as high blood pressure and congestive heart failure. Additionally, L-Arginine is used to increase the strength of the immune system and improve circulation issues including erectile dysfunction.

Finally, some evidence indicates that L-Arginine may also play a role in reducing the recovery time of injuries as it has an anti-inflammatory effect.

Research has shown that L-arginine can help to increase vasodilation (widening of the blood vessels) which may in turn help medical conditions such as chest pain, atherosclerosis (clogged arteries), heart disease or failure, erectile dysfunction, intermittent claudication/peripheral vascular disease and vascular headaches (headache-inducing blood vessel swelling).

Supplementation with L-arginine has also been found to improve nitric oxide production and exercise capacity in both healthy subjects and those with chronic disease, such as diabetes and heart failure.


L-Lysine is another essential amino acid which is necessary for human health. To date, studies have shown that L-Lysine could play a role in reducing cortisol levels in the body and can effectively lower stress levels. It is therefore possible that L-Lysine may help with relaxation. Furthermore, L-Lysine is being studied for its ability to fi ght cancer. Evidence also suggests that L-Lysine is a powerful immune system booster and has the ability to fight cold sores and the herpes virus.


The amino acid L-Citrulline is similar to L-Arginine in that L-Citrulline can also boost nitric oxide levels in the body and relax blood vessels. In fact, our bodies naturally convert L-Citrulline into L-Arginine. This can translate into benefits for heart health and other blood fl ow issues such as erectile dysfunction. L-Citrulline is considered to be a strong amino acid that can be used for boosting energy and increasing athletic performance. Research also points towards L-Citrulline’s potential use in Alzheimer’s disease.



Contains 1,500mg of L-Lysine added to 5,000mg of L-Arginine and 200mg of L-Citrulline, 50mg AstraGin (to dramatically improve absorption of the amino acids), 150mg of Grapeseed Extract and 25mg of Polyphenols to make this the number one amino acids supplement!
