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.

This is a great duo
This set is amazing!... It smells amazing, it is so moisturizing and smooth on the skin. I love the subtle shimmer it leaves on the skin. I will say that, based on the climate or weather differences, you can feel the difference. For example, in Las Vegas, this sinks right into the dry skin and leaves you feeling well hydrated on your skin. When I'm in places like FL, the high humidity can leave this product feeling a little over-hydrating and the skin a little "tacky," but this is truly a person by person try it and find out for yourself. Either way, I love it and highly would suggest this for anyone that loves a good shimmer (light but hits great in the sun) and high moisturizing properties

Will buy again!
This smells AMAZING. Immediately after I opened up the whipped lotion, I was hit with an intense coco butter smell. The oil has the same affect, only with a gorgeous shiny finish. Both the oil and the butters consistency is perfect, the lotion doesnt feel too thick and the oil doesnt leave me slipping and sliding lol. There is shimmer in it but it doesnt look like Ive covered myself in glitter so i love that. The moisture lasts for such a long time especially when applied right after a shower. My skin absorbed it very nicely without feeling sticky or like there is any left over residue. The price for two was absolutely worth it10/10 will reorder after I run out.
