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.

Very spacious and beautiful
Size: 23.6 Inch, Color: White, Size: 23.6 Inch, Color: White
A lot of my books fit on here and there’s still more room left if I wanted to buy more books. It’s a simple looking bookshelf but it’s really pretty. It’s also sturdy the only reason I gave it a 4 stars instead of 5 was because it comes with its own plastic screw anchors and they are crap. The shelves were wobbly when we installed them using the plastic screw anchors that came with the packaging. My dad set mine up and luckily he had a bunch of his own so he switched them out with better screw anchors. Once we made that switch it was perfect, there was no wobble or shaking at all. So that’s my only piece of advice. Besides for the screw anchors everything else is perfect

Super easy to install. I use different wall anchors. The anchors like all anchors that come with shelves are not great. The shelves look very clean on the wall.

This product exceeded my expectations. The installation process was incredibly straightforward—even for someone with little to no experience—and the instructions were clear and easy to follow. Once installed, it feels very sturdy and secure, with no wobbling or shifting at all. You can tell it’s well-designed and made with quality materials. I also appreciated how quickly I was able to set everything up without needing any extra tools or help. Overall, it’s a reliable, user-friendly product that I would absolutely recommend to anyone looking for something dependable and easy to install. Drill is required though.

Don't buy
Size: 23.6 Inch, Color: White
The shelf is very flimsy and not sturdy at all. It feels unstable and poorly made. Definitely not worth the money, I wouldn’t recommend wasting your time or money on this product.
