Essential amino acid for hepatic, urinary and cardiovascular protection.
This amino acid is a precursor to the amino acids cysteine and cystine. It was first isolated by John Howard Mueller in 1921.
Health benefits of methionine
- Hepatic protection: it reduces the accumulation of heavy metals; it lowers cholesterol and triglycerides levels; alongside choline and inositol, this essential amino acid reduces the accumulation and fat deposits in the liver due to the lipotropic effect; it converts estradiol into the nontoxic form called estriol (it protects the liver during the estrogen metabolism).
- Improving energy metabolism of the muscle cell that stimulates the production of creatine.
- Digestive problems account for nearly 10 percent of all healthcare spending and a least 70 million Americans suffer from some sort of digestive illness. this amino acid is important in gut health.
- From 2013- 2015, an estimated 54.4 million people in the United States have suffered from some form of arthritis. Consuming supplement with this amino acid improves the structure and mobility of joints.
- This amino acid provides the body sulfur and other substances necessary for a proper development. Sulfur is a very important element, whose lack leads to the body’s inability to produce certain antioxidants.
- It is vital for the transportation and absorption of zinc and selenium in the body. These two essential minerals act just line an antioxidant within the body, slowing the aging process and fighting free-radical damage.
- Cardiovascular disease accounts for nearly 801,000 deaths every year in the United States. That’s about 1 of every 3 deaths. This amino acid provides cardiovascular protection by reducing fat levels in the bloodstream and atheroma plaque formation.
- Higher levels of this amino acid in the daily diet is strongly connected with a lowering in pancreatic cancer risk.
- Urinary tract protection: it prevents adherence of bacteria to the bladder wall and their proliferation; it reduces the occurrence and formation of kidney stones.
- As many as 1 million people in the United States live with Parkinson’s disease, that is more than the combined number of patients diagnosed with muscular dystrophy, multiple sclerosis, and Lou Gehrig’s disease. According to research, consuming foods high in this amino acid helps in treating and reducing the symptoms of Parkinson’s disease.
- Maintaining the structure of hair, skin, and nails: it stimulates collagen production.
- In 2015, 39,513 individuals were diagnosed with HIV infection in the US. This amino acid may help in HIV/AIDS treatments.
Some individuals with a deficiency in this amino acid may experience the following symptoms – problems with skin integrity, coordination and muscle strength, and detoxification of the liver.
An adult should intake approximately 19 mg of this amino acid/ kilo of body weight every day.
However, special circumstances and conditions may lead to a much higher requirement.
Large amounts of this amino acid can be found in: eggs, sesame, meat, wheat, wheat bran, oats, oat bran, millet, hazelnuts, pecans, peanuts, almonds, pumpkin seeds, chia seeds, sesame seeds, flax seeds, pine seeds, watermelon seeds, sunflower seeds vegetables, fruits (apples, mangoes, papayas, pineapples) and legumes (peas, red kidney beans, navy beans, adzuki beans, mung beans, lentils, soybeans, chickpeas).
