Arginine is a conditional amino acid, which means it can be manufactured by the body. However, in times of illness and stress, more may be needed than the body can produce. Arginine is found in foods such as dairy, meat, and fish. As a dietary supplement, “free form” L-arginine is easier for the body to utilize, as free form amino acids are already singular molecules that don’t require digestion.

Arginine supports healthy heart function, strengthens the immune system, improves healing, and enhances the power, strength, intensity, and recovery of muscles. It also increases the production of nitric oxide, a substance that dilates blood vessels, aids in circulation, lowers blood pressure, and helps prevent atherosclerosis. As a result, arginine is able to protect the cardiovascular system against atherosclerosis, high blood pressure, blood clots, high cholesterol, and other conditions.

Arginine stimulates protein synthesis and increases the force and power of skeletal muscle, which helps athletes and bodybuilders increase strength, optimize lean body mass, increase performance, and promote recovery. High intensity training weakens the immune system and can cause inflammation and injury. Arginine counteracts these effects by enhancing immune function, decreasing inflammation, and improving wound healing. It’s especially important for athletes who train intensively, as they require extra support during training and a shorter recovery period.

How it works

Arginine is an amino acid that is involved in protein production, wound healing, and the production of nitric oxide and other important compounds. Nitric oxide is a molecule that is involved in many physiological processes, especially in the cardiovascular system. Many diseases are associated with low production of nitric oxide including diabetes, heart disease, high cholesterol, high blood pressure, obesity, and aging. Nitric oxide dilates blood vessels, increases blood flow, improves functioning of the endothelium, and inhibits platelet aggregation and smooth muscle proliferation. These effects help maintain normal cardiovascular function and blood pressure, and protect against oxidative damage. 

In skeletal muscle, arginine causes the release of nitric oxide, prostaglandins, and other powerful compounds that increase muscle force and power, stimulate protein synthesis, maintain glucose homeostasis, and increase blood flow to muscles. 

Arginine stimulates the release of hormones from the pituitary and adrenal glands, including growth hormone, insulin, and glucagon, which may help bodybuilders increase muscle strength and lean body mass. Arginine promotes protein synthesis, improves collagen deposition, improves wound strength, decreases inflammation, and strengthens the immune system, making it an important supplement for wound healing.

Just Okay
Color: Suitcase - Black
Speakers are crap, but you can connect others, which is good I guess. Simple functionality, probably best for the "turn the page" books for toddlers. The Black Keys are sad.

I love this!
Color: Suitcase - Black
Okay, I was born in 1985, of course I’ve always known that vinyls exist but never seen one work like live, forget about me putting it to play a record, so… this is my first record player I’ve ever bought, I did do some research before getting it and I was lucky to have gotten it because now it says “currently unavailable”, but I’m happy with my purchase and I do hope that Amazon make more of these for everyone who wants one, maybe even upgrade it a little bit… sounds good and clear but you can always hook it up to some speakers for more bass or volume. I haven’t tried the bluetooth yet so I’m not really sure what can you pair or not. It has Auto-stop so at the end of the side of the vinyl, it stops spinning. The briefcase appearance makes it stay on the vintage realm and is easy to carry and I liked the fabric used instead of vinyl-leather material like because they tend to deteriorate.
