Amino acids are the subunits or ‘building blocks’ of protein. From blood production to building up the body’s many tissues, we ultimately need protein to survive. The problem is that we can’t get all the protein we need from our body’s natural processes. Therefore, we need to consume them (amino acids) from dietary or supplemental sources.

Amino acids are found in the majority of foods we consume. The most plentiful sources are beef, fish, poultry, eggs, dairy products, seeds, and legumes. Our body separates these protein sources into amino acids during the digestive process.

Again, the human body can make, or synthesize, a number of amino acids. However, we only produce 13 of the 22 amino acids needed for proper physiological functioning. The 13 amino acids our bodies can make are called nonessential. The 9 we cannot manufacture are called essential aminos – because it is essential that we obtain them from external sources.

Essential amino are available in thousands of dietary supplements. They can be combined with other amino acids or can be sold alone. Most amino acids are manufactured in the Levo, or L-forms. Unlike the Dextro or D- forms, the L-form amino acids are more effective for humans as they are more compatible with human biochemistry.

Some of today’s most popular L-form amino acid supplements include;

Arginine:

This nonessential amino acid is among the most popular of all amino acids. It is sometimes referred to as a conditionally or semi essential amino because it is nutritionally essential in infants. In adults, it can also become essential in times of extreme stress to the human body (e.g. burn, injury, and infection).

Arginine has a myriad number of physiological applications, including; immune system functioning, hormone secretion, and ammonia detoxification. However, in recent years its popularity has sky rocketed on account of its nitric oxide-inducing effects.

Arginine is a precursor to nitric oxide – a compound that has been shown to relax blood vessels. This has lead to applications in the areas hypertension, preeclampsia, intermittent claudication, and erectile dysfunction. Some scientific data also supports its use as a muscle-enhancing supplement. However, this data is limited. Some experts believe that arginine’s performance-enhancing action is directly due to its ability to enhance growth hormone levels.

Isoleucine:

Isoleucine is an essential amino that must be obtained by diet or external sources, like dietary supplements. Isoleucine is one of three branched-chained amino acids (BCAAs). The others are leucine and valine. BCAAs are critical for our muscle tissues. They are thought to promote muscle recovery and enhance exercise performance when taken in conjunction with rigorous physical training.

Alone, isoleucine is critical for regulating blood sugar levels in the body. This, in turn, assists with energy production in the body. Isoleucine is equally important in the formation of hemoglobin and blood clots.

Lysine:

Lysine is an essential amino found in small quantities in leafy green vegetables. It is essential for the production of carnitine. Carnitine is a nutrient that assists with energy production in the body; more specifically, it helps the body convert fatty acids into energy.

Lysine, itself, is required for numerous physiological processes. These include collagen formation and assisting with calcium absorption and calcium conservation throughout the body. Adequate lysine intake is vital for the health of the bones, cartilage, tendons, and skin.
