Trimethylamine N-oxide (TMAO)

Trimethylamine N-oxide (TMAO) is a compound produced in the liver from trimethylamine (TMA), which is generated by gut bacteria during the digestion of nutrients like choline, L-carnitine, and phosphatidylcholine. Elevated levels of TMAO have been linked to an increased risk of cardiovascular disease, kidney dysfunction, and inflammation. TMAO serves as a valuable marker for assessing metabolic health and the impact of gut microbiota on systemic disease risk. Lifestyle and diet, especially red meat and eggs, can significantly influence TMAO levels. Monitoring TMAO may help identify hidden risks even when other conventional markers appear normal.

Description

What does a high TMAO level indicate?

Elevated TMAO levels are linked to an increased risk of cardiovascular disease, atherosclerosis, kidney dysfunction, and systemic inflammation.

What causes TMAO levels to increase?

Diets high in red meat, eggs, and other animal products rich in choline and carnitine can increase TMAO levels. The composition of gut microbiota also plays a significant role.

Can TMAO levels be reduced?

Yes, TMAO levels can be lowered by making dietary changes (such as cutting back on red meat), increasing fiber consumption, and altering gut microbiota with probiotics or prebiotics.

Is TMAO testing beneficial if my cholesterol levels are normal?

Yes. TMAO may indicate cardiovascular or metabolic risks that standard lipid panels do not detect, making it a complementary marker for preventive health screening.

Is TMAO influenced by gut health?

Absolutely. TMA is produced by gut bacteria, so the balance and diversity of your microbiome directly affect how much TMAO is ultimately formed.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the USA. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
