What's this test for?

This test is ideal if you're concerned about your heart health, especially if you have moderate or high risk factors for cardiovascular disease. It measures TMAO, a chemical produced by gut bacteria when you eat certain foods like red meat, eggs, and fish, which has been linked to increased risk of heart attacks and strokes. Many people use this test to better understand their cardiovascular risk beyond traditional cholesterol testing, particularly if they have a family history of heart disease or other risk factors.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your TMAO levels mean for your heart health and cardiovascular risk. These notes include personalized recommendations like dietary changes (particularly regarding red meat and animal products), gut health improvements through probiotics, and lifestyle modifications to support heart health. You'll also get the standard lab report and can track your TMAO levels over time using our trends feature to see how dietary and lifestyle interventions are working.

What's included in this test?

This test measures TMAO (Trimethylamine N-oxide), a compound produced when gut bacteria break down certain nutrients found in red meat, eggs, and seafood. Elevated TMAO levels have been associated with increased risk of heart attacks, strokes, and other major cardiovascular events, making it a valuable marker for assessing heart disease risk beyond traditional cholesterol and lipid panels.

How should I prepare for this test?

You should fast overnight before your blood draw, which means no food or drinks except water for 8-12 hours. It's also important to avoid eating fish and other seafood the day before your test, as these foods can temporarily elevate TMAO levels and may lead to inaccurate results. Take your test in the morning after fasting for best results.

Who should consider getting this test?

This test is particularly valuable for people with moderate to high cardiovascular disease risk, including those with high cholesterol, high blood pressure, diabetes, or a family history of heart disease. It's also useful for anyone looking to optimize their heart health through diet, especially those who consume a lot of red meat, eggs, or animal products, or individuals who want a more comprehensive picture of their cardiovascular risk beyond standard cholesterol testing.

What symptoms indicate I may need this test?

While TMAO itself doesn't cause specific symptoms, you might consider this test if you're experiencing signs that could indicate heart problems, such as chest discomfort, shortness of breath during activity, unusual fatigue, or if you have risk factors like being overweight, having high blood pressure, or diabetes. It's also worth considering if you have a family history of early heart disease or stroke, even if you feel fine now.

How can I naturally lower my TMAO levels?

Reducing your intake of red meat, egg yolks, and high-fat dairy products can help lower TMAO production since these foods contain compounds that gut bacteria convert to TMAO. Eating more plant-based foods, including plenty of fruits, vegetables, whole grains, and legumes, supports healthier gut bacteria. Taking probiotics or eating fermented foods like yogurt, kimchi, and sauerkraut may also help by promoting beneficial gut bacteria that don't produce as much TMAO.

What is TMAO and why does it matter for heart health?

TMAO is a compound created when gut bacteria digest certain nutrients found mainly in animal products like red meat, eggs, and seafood. Research has shown that high TMAO levels are associated with increased risk of heart attacks, strokes, blood clots, and cardiovascular death. It appears to promote inflammation and atherosclerosis (hardening of the arteries), making it an important emerging marker for cardiovascular risk assessment.

What does high TMAO mean?

High TMAO levels suggest an increased risk of cardiovascular events like heart attacks and strokes. Elevated levels may indicate that your gut bacteria are producing excess TMAO from your diet, or that your body isn't clearing it efficiently. This doesn't mean you'll definitely have heart problems, but it signals that dietary changes and heart health optimization should be prioritized.

How often should I retest my TMAO levels?

If you're making dietary changes to lower your TMAO, retesting in 3-6 months can help you see if your interventions are working. For ongoing cardiovascular risk monitoring, especially if you have other risk factors, testing every 6-12 months is reasonable. If your initial levels are normal and you maintain a heart-healthy lifestyle, annual testing or testing as part of your regular cardiovascular screening may be sufficient.
