What does TMAO do in the body?
Trimethylamine N-oxide (TMAO) is a small colorless amine oxide generated from choline, betaine, and carnitine by gut microbial metabolism. It accumulates in the tissue of marine animals in high concentrations and protects against the protein-destabilizing effects of urea.
What foods are high in TMAO?
Sources of TMAO Beef and lamb are the most dangerous—they contain about 50 to 160 mg of carnitine per serving, compared to between 3 and 7 or 8 mg in pork, seafood, chicken, and high-fat dairy products. Egg yolks also contain high amounts of choline.
How do I get rid of TMAO?
The liver then converts TMA into the compound, trimethylene N-oxide (TMAO).
What does high TMAO mean?
“The higher someone’s level of TMAO is, the more susceptible that person is to accumulation of cholesterol in the artery wall. This increases the risk of a heart attack or stroke,” reports Stanley Hazen, MD, PhD., Vice Chair of Translational Research at the Lerner Research Institute.
How bad is TMAO?
In one of those studies, researchers found that people with higher levels of TMAO in their blood may have more than twice the risk of heart attack, stroke, or other serious cardiovascular problems, compared with people who have lower levels.
Is TMAO carcinogenic?
For example, TMAO was suggested to be involved in molecular pathways that lead to the generation of N-nitroso compounds 66, which were known to induce DNA damage, an event that can contribute to carcinogenesis 67. This suggests a potential involvement of DNA damage in TMAO-contributed carcinogenesis.
Do vegetables produce TMAO?
After eating foods rich in TMAO, such as fish and vegetables, the levels of TMAO in the blood are significantly elevated, and the liver produces TMAO from TMA, trimethylamine (made by the gut bacteria)….Privacy Overview.

Do eggs contain TMAO?
TMAO can form after eating foods that contain choline, an important nutrient for brain health found in egg yolk, fish, poultry, and red meat. It can be measured in the blood but is actually produced in the gut.
How does TMAO cause atherosclerosis?
TMAO is identified as a promoter of atherosclerosis by enhancing the formation of foam cells and atherogenic plaque in mice [4], [5]. However, the underlying mechanism that how TMAO promotes atherosclerosis is not fully understood. Endothelial dysfunction plays a role in the pathogenesis of atherosclerosis.
Is choline bad for your heart?
Can choline be harmful? Getting too much choline can cause a fishy body odor, vomiting, heavy sweating and salivation, low blood pressure, and liver damage. Some research also suggests that high amounts of choline may increase the risk of heart disease.
Where is TMAO found?
Trimethylamine (TMA) is formed in the intestinal lumen when gut microbiota metabolize carnitine, choline, and choline-containing compounds in the diet. TMA can be absorbed from the intestine. This absorbed TMA is delivered to the liver where flavin-dependent monooxygenase (FMO) isoforms 1 and 3 convert it to TMAO.
What is TMAO egg?
Eggs, and especially egg yolks, are a major dietary source of choline. Ingestion of choline supplements has been linked to an increased concentration of a compound called TMAO (trimethylamine N-oxide). Elevated TMAO levels have been linked to higher heart disease risk.
What does TMAO stand for?
Rather, TMAO stands for Trimethylamine N-oxide, and it is set to become the reigning king of the “why meat is bad for you” argument. Former contenders, cholesterol and saturated fat, have apparently lost their mojo.
Is TMAO from fish, meat and eggs harmful?
According to new stories, fish, a staple of the Mediterranean diet, as well as meat and eggs may be doing more harm than good thanks to a compound called trimethylamine-N-oxide (TMAO). TMAO is found in fish and produced in the body after eating meat and eggs.
What exactly is TMAO?
What Is TMAO? TMAO stands for trimethylamine N-oxide, which comes from trimethylamine. It’s what plants and animals produce when they decompose. The body, however, also produces trimethylamine, particularly the gut microbiota.
What foods are rich in dietary TMAO precursors?
Food that contain TMAO producing components is the made by the precursor L-Carnitine. This is in the red meats that we enjoy such as beef, lamb, pork and other wild game, cows and sheep milks, dairy products and fish of any kind.
