Your guide to LDL size.
Discover the role of LDL size in your health and longevity with Mito Health's advanced biomarker analysis. Our detailed reports cover key biomarkers, providing essential insights to help you make informed decisions for a healthier, longer life.
What is LDL size?
LDL size refers to the average diameter of low-density lipoprotein (LDL) particles in the blood.
LDL particles can vary in size, with larger, buoyant particles being generally less atherogenic (less likely to cause plaque buildup in the arteries) than smaller, denser particles, which are more prone to oxidation and arterial penetration.
What does it assess?
LDL size assesses cardiovascular risk and overall lipid health.
LDL size is an important marker, especially for individuals with metabolic syndrome, type 2 diabetes, or insulin resistance, as these conditions often increase the prevalence of small, dense LDL particles.
How do I optimize my LDL size?
Omega-3 fatty acids, found in fatty fish and flaxseeds, help reduce inflammation and encourage larger LDL particles.
Monounsaturated fats from sources like olive oil, nuts, and avocados also support healthier LDL particle size by reducing the presence of small, dense LDL.
Physical activity, particularly aerobic exercise, can increase insulin sensitivity and reduce small, dense LDL particles.
Resistance training also positively influences LDL particle size and lipid profile over time.
Reducing alcohol intake can help prevent triglyceride spikes, which contribute to the formation of smaller LDL particles.
Moderation is key to supporting healthier lipid and particle profiles.
What do large and small LDL sizes mean?
Larger LDL particles are generally less harmful and are associated with a lower risk of atherosclerosis.
A high average LDL size indicates healthier lipid transport and a reduced likelihood of plaque buildup.
Smaller, dense LDL particles are more likely to penetrate arterial walls and oxidize, contributing to a higher risk of plaque buildup and cardiovascular disease.
A low LDL size is often associated with metabolic issues, such as insulin resistance, higher triglycerides, and increased inflammation, all of which elevate cardiovascular risk.
