While TMAO did not change after probiotic supplementation, there was a significant increase in betaine plasma levels. In contrast, the placebo group showed a significant decrease in plasma choline levels. Short-term probiotic supplementation does not appear to influence plasma TMAO levels in HD patients.
Simply so, What foods increase TMAO? TMAO levels in the blood significantly increase after eating TMAO-rich food such as fish and vegetables. In addition, the liver produces TMAO from trimethylamine (TMA), a substance made by gut bacteria.
Do eggs increase TMAO? A randomized controlled study indicates that the consumption of 2 or more eggs significantly increases the TMAO in blood and urine, with a choline conversion rate to TMAO of approximately 14%.
Subsequently, How do you lower a Tamo?
Research suggests that subjects with high TMAO should consider switching to a heart-healthy Mediterranean or plant-based diet, since adherence to the Mediterranean diet has been shown to reduce TMAO levels.
What causes high TMAO?
TMAO (trimethylamine N-oxide) is produced by gut bacteria from choline, lecithin, and L-carnitine-rich foods (mainly fish, meat, egg, and dairy). High levels are associated with heart disease, hardening of the arteries, diabetes, and colon cancer.
What is a normal TMAO level? Reference Interval
| TMAO Medical Decision Limits | |
|---|---|
| Low | <6.2 µM |
| Moderate | 6.2−9.9 µM |
| High | >9.9 µM |
How can I lower my TMAO naturally?
To lower your TMAO levels, consider minimizing the consumption of full-fat dairy products, including whole milk, egg yolk, cream cheese, and butter; both processed and unprocessed red meat (beef, pork, lamb, and veal), as well as nutritional supplements and energy drinks containing choline, phosphatidylcholine ( …
Why do fish reduce TMAO? Reduction of TMAO to Trimethylamine
The presence of TMAO contributes to a relatively high redox potential in the flesh since the Eh of the TMAO/TMA couple is +19 mV. The presence of TMAO has been suggested as an extra hurdle against anaerobic bacteria in salted fish.
Is TMAO toxic?
According to a news article published June 11 in JAMA, three recent analyses have linked high blood levels of TMAO with a higher risk for both cardiovascular disease and early death from any cause.
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.
Does fish contain TMAO?
Fish and other seafoods contain significant quantities of free TMAO, in addition to the TMA precursors (phosphatidylcholine, choline, and carnitine) found in meat, eggs, and milk products.
Does L-carnitine increase TMAO? L-carnitine, which can be metabolized to TMA, is a primary metabolic precursor for TMAO. Dietary L-carnitine supplementation can significantly increase serum TMAO levels in both human and rodents (4, 13). Oral L-carnitine treatment could also promote atherosclerosis in ApoE knockout mice (10).
Is Salmon High in TMAO?
The TMAO content is higher in cod compared to salmon [28], and we recently demonstrated that high cod intake, but not high salmon intake, markedly increased the TMAO concentration in serum and urine of this study population as a result of high TMAO intake from cod fillet [28].
How is TMA formed?
TMA and DMA are produced from trimethylamine oxide (TMAO) by spoilage bacteria. Ammonia can be formed by various catabolic routes such as the decomposition of urea, amino acids and nucleotides by urease and deaminase.
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.
Does TMAO cause inflammation?
AS is considered a chronic inflammatory disease initiated by vascular endothelial inflammatory injury. Both observational and experimental studies suggest that TMAO can cause endothelial inflammatory injury. However, a clear mechanistic link between TMAO and vascular inflammation of AS is not yet summarized.
Does fish oil contain TMAO?
To date, we know that TMAO is found in high levels in certain types of seafood. A comprehensive list of the contents in supplements are rarely listed, so it is possible that TMAO may be present in fish oil/krill oil supplements.
How is TMAO excreted? Approximately 50% of the ingested TMAO is absorbed unchanged and then excreted in urine. The remaining 50% is converted into TMA in the gut by the action of TMAO reductase [19]. TMA can be oxidized to TMAO again by the action of TMA monooxigenase, which is present in some gut microorganisms [21,22] (Figure 1).
What is high TMAO?
Excess TMAO production is a type of gut dysfunction indicating the intestine (primarily large intestine) has excess bacteria capable of producing TMAO. The TMAO test does not indicate the location of TMAO producing bacteria in the gut, only the presence.
Does Chicken increase TMAO? Two studies published Monday show that people who eat red meat — but not vegetarians or people who eat only white meat such as chicken — produce more of a chemical called TMAO, which has been shown to raise heart disease risk.
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).

What is TMAO egg? Eggs, and especially egg yolks, are a major dietary source of choline. Choline can also be given as a dietary supplement. 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 is the difference between TMA and TMAO?
Choline, a trimethylamine-containing compound and part of the head group of phosphatidylcholine, is metabolized by gut microbiota to produce an intermediate compound known as trimethylamine (TMA). TMA is rapidly further oxidized by hepatic flavin monooxygenases to form trimethylamine N-oxide (TMAO).
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.
How do you treat trimethylaminuria?
Treatment for trimethylaminuria mainly includes diet modification, acidic soaps and lotions, and vitamin B12 supplements. Other treatment options include antibiotics , activated charcoal, and probiotics.
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.
