Our free-form L-Arginine is HPLC verified ultra-pure for maximum bioavailability and effectiveness. Arginine (or L-Arginine) is a crystalline free-form amino acid involved in numerous areas of human biochemistry, including muscle metabolism, hormone secretion, ammonia detoxification, and the immune system. Arginine promotes nitric oxide production, which helps support circulation and muscles.

L-Arginine is one of 20 amino acids, the building blocks of protein. Arginine can serve as a source of energy, and is involved in various pathways throughout the body. Arginine supports the effect of exercise and is one of the most important amino acids involved in immune function.L-Arginine is considered a semi-essential amino acid, because although it is normally synthesized in sufficient amounts by the body, supplementation is sometimes required. Arginine supports protein synthesis as it is involved in the transport and storage of nitrogen and is important for proper physical performance because it is used by the body to produce creatine.

L-Arginine is required for the synthesis of nitric oxide, a secondary messenger involved in blood flow. Nitric oxide is a compound that helps keep blood vessels dilated to promote healthy blood flow. Arginine also stimulates protein synthesis and has been studied for wound healing, bodybuilding, enhancement of sperm production (spermatogenesis), and prevention of wasting in people with critical illness. L-Arginine is beneficial for overall cardiovascular maintenance as well as other areas that depend largely on healthy circulatory status.

Arginine Improves Growth Hormone (GH) levels:

Arginine stimulates the natural release of growth hormone and is a far safer and more cost effective alternative to growth hormone treatment such as HGH injections. Growth hormone is one of the most powerful hormones in the human body which promotes the growth of lean muscle tissue and the loss of fat. As you age, growth hormone levels drop, which is one reason you lose muscle and gain fat. In a controlled trial, when arginine and other amino acids were combined with weight training, a greater decrease in body fat was obtained after only five weeks than when the same exercise was combined with a placebo. Arginine is also needed to increase protein synthesis, which can in turn increase muscle growth. [1,2].

Growth Hormone (GH) for the athlete:

Athletes involved in intense exercise on a regular basis need Growth Hormone (GH) to increase energy, enhance lean body mass and to maintain strong bones and keep their weight under control. Availability of GH in systemic circulation also helps increase strength, burn fat, enhance libido, boost immunity and support tendons and ligaments. By inducing the secretion of GH from the pituitary, arginine and lysine stimulate muscle metabolism and, hence, provide nutritional support for the athlete.

Very thin & no support
Size: Queen (U.S. Standard)
I was thinking these pillows were going to be kind of firm with the way they are described and the picture but they are very thin and when I laid down on it, it was like whatever is in the pillow just instantly moved to each side of my head. Definitely not for me and my neck issues.

Back sleeper here
Size: Standard
So since they were listed as down alternative, I was interested to see if they had that artificially puffy feel to them. They do get puffed up really well after a day. And the fabric is cool and comfortable. I do feel like these have good quality stuffing and the cover feels nice. I'm a back sleeper and it's just the right amount of bulk under my neck. I usually bunch the pillow up a little bit there so there's a little more pressure under my neck but with these it just felt good to lay on it without having to bunch it up in any special way. So I would definitely recommend them. So far I'm really liking having these pillows.

Nice and Fluffy
Size: Standard
These "down alternative" pillows have been a winner for me. Came two to a package and once they have a couple of days our of the vacuum packaging are nice and fluffy with no noticable odor. Just the right amount of "spring" to them for my taste. Also don't overheat my face/neck as traditional down pillows sometimes have.

Hotel Grand Set of 2 pillows
Size: King
Excellent quality and comfort. The pillows are soft but with the perfect support, ideal for any sleeping position. They feel fresh thanks to the cotton cover and keep their shape very well. Without a doubt, a great purchase for a hotel-like break at home.

Highly recommend
Size: King
These pillows are super comfortable and feel just like hotel quality. They’re soft but still give great support for my neck and head. I’ve been sleeping much better since I got them. They stay fluffy and don’t go flat, and the material feels nice and cool. Definitely a great purchase
