Ornithine, a non-proteinogenic amino acid, is the star component of Shijimi. It plays a crucial role in the urea cycle, detoxifying ammonia and supporting liver functions. But its benefits extend beyond the liver.
Ornithine is a type of nonessential amino acid[*1] that originally exists in the body, supporting the function of the liver and helping to relieve fatigue. Ornithine belongs to the "free amino acids" among amino acids that do not stay in the liver or muscles but circulate in the blood.
Ornithine dissolves in the blood, circulates in the body, detoxifies harmful ammonia in the liver, and supports liver function. The liver is the largest organ in the human body, consisting of about 300 billion cells and weighing 1 to 1.5 kg for an adult, or about 1/50th of the body weight.
The reason why people say "shijimi soup is good for a hangover" is because ornithine contained in high amounts in shijimi works on the health of the liver.
In Japan, the health benefits of shijimi were known before the health benefits of ornithine, and it is said that during the Edo period (1603-1868), shijimi clam vendors sold shijimi clams in baskets.
Today, research is being conducted on the health effects of ornithine, a health component of shijimi, and many health foods, such as supplements, contain ornithine.
Ornithine is abundantly contained in whitebait. It is also found in cheese, flounder, and bread.
Since it is necessary to take a very large amount of ornithine from foodstuffs, supplements and other health foods are an efficient way to consume ornithine.
Ornithine is found in familiar foods such as shijimi clams, and the recommended intake amount is considered to be 500 mg to 1000 mg per day. In clinical trials, it may be administered at 1g to 2g per day.
Ornithine's effects on the human body are multifaceted. From liver detoxification to skin health, its benefits are vast and well-documented.
Ornithine works on the "ornithine cycle" in which the liver breaks down ammonia, which is harmful to the body, and can be expected to have a fatigue-relieving effect.
Ammonia is one of the waste products produced when humans generate energy, and when ammonia is produced in excess in the body, the whole body tends to feel tired.
Toxic ammonia is detoxified by the liver. This process is called the "ornithine cycle," which converts ammonia into harmless toxins.
In addition, ornithine has been shown to reduce stress and improve sleep, mood, and other subjective symptoms. It has been suggested that ornithine can improve sleep and have a calming effect on mood when taken by people who feel fatigued on a regular basis, and as a result, people who take ornithine have been found to have lower stress states.
Ornithine has the effect of enhancing liver function.
Nine subjects with liver function requiring attention and one healthy subject were asked to take 6 capsules of 220 mg powder of Shijimi clam extract, which is rich in ornithine, before each evening meal, and after 13 weeks, they took 6 capsules every morning before dinner, for a total of 12 capsules per day.
Blood tests were conducted every two weeks from the beginning of the study to check the index values of liver function, and it was found that the function of the liver was enhanced.
Ornithine helps build muscles and bones, and also stimulates the secretion of growth hormones that regulate skin tone. As a result, it promotes the rebirth of skin cells and supports metabolism.
Ornithine has the effect of stimulating the secretion of growth hormones and metabolism, which is the rebirth of cells.

This Ornithine peptides are recommended for people:
1] Ornithine is thought to have the effect of reducing exercise fatigue, as 17 healthy adults were given ornithine at a dose of 6 g per day for 7 days, and the amount of ketone bodies and urinary ammonia due to exercise fatigue were improved, as well as the feeling of fatigue.

2] Ornithine is thought to have a hepatoprotective effect, as rats with hepatic impairment were fed ornithine-aspartic acid at a dose of 2 g/kg for 10 days, and their hepatic impairment was ameliorated.
https://pubmed.ncbi.nlm.nih.gov/21189911
3] Ornithine and arginine were administered to 17 healthy adults along with training, and the increase in growth hormone and insulin-like growth factor was observed, suggesting that ornithine may have a growth-promoting effect.
https://pubmed.ncbi.nlm.nih.gov/20300016
4] Arginine is known to promote collagen synthesis, which is necessary for wound healing. Since ornithine is also converted to arginine through the urea circuit, ornithine is thought to have skin protective properties.

5] When 22 adult males were given 4 g/day of ornithine and arginine (containing 2 g of L-ornithine) for 5 days along with training, muscle strength and lean body mass increased and urinary hydroxyproline levels decreased, suggesting that ornithine has a muscle-strengthening and strength-maintaining effect. Ornithine is thought to have a muscle-strengthening and muscle-maintaining effect.
