ADMA – Endothelial Function & Cardiovascular Risk Marker

ADMA – Endothelial Function & Cardiovascular Risk Marker

The ADMA test measures Asymmetric Dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthesis and an important biomarker related to endothelial function, vascular health, and cardiovascular risk.

ADMA has gained increasing attention in preventive and functional medicine because elevated levels may reflect impaired nitric oxide availability, which can negatively influence vascular tone, blood flow regulation, and cardiometabolic health.

What does this test measure?

• Asymmetric Dimethylarginine (ADMA)

Why is ADMA important?

ADMA acts as a natural inhibitor of nitric oxide synthase. Nitric oxide is essential for healthy endothelial function, proper vasodilation, and vascular signaling. When ADMA is elevated, nitric oxide production may be reduced, which may contribute to endothelial dysfunction and increased cardiovascular risk.

Clinical relevance

ADMA may be useful in the assessment of vascular function, metabolic health, and early cardiovascular risk, especially in patients with hypertension, insulin resistance, diabetes, chronic inflammation, oxidative stress, or suspected endothelial dysfunction.

It may also be relevant in broader preventive health strategies and in functional medicine evaluations where nitric oxide balance, vascular performance, or methylation-related pathways are of interest.

When may this test be considered?

• Cardiovascular risk assessment
• Suspected endothelial dysfunction
• Hypertension
• Insulin resistance or metabolic syndrome
• Diabetes-related vascular monitoring
• Chronic inflammation or oxidative stress
• Preventive longevity-focused evaluation

How can elevated ADMA be interpreted?

Elevated ADMA may suggest reduced nitric oxide bioavailability and impaired endothelial regulation. Interpretation should always be made in the context of the patient’s cardiometabolic profile, inflammatory status, renal function, and related vascular risk markers.

Suggested complementary tests

• SDMA
• Homocysteine
• Lipid profile and ApoB
• HbA1c and fasting insulin
• hs-CRP
• Oxidative stress markers
• Elements and micronutrient status

Who is this test for?

This test is suitable for practitioners and individuals seeking a deeper view of vascular and endothelial health, especially when standard cardiovascular markers do not fully reflect the broader functional risk profile.

Important note

ADMA should not be interpreted as a standalone cardiovascular diagnosis. It is best used as part of an integrated assessment including metabolic, inflammatory, renal, and vascular-related biomarkers.
