What Is Lipoprotein(a) and Why Should You Care?
Lipoprotein(a), often written as Lp(a), is one of the most important cardiovascular risk factors that most people have never heard of. Unlike LDL cholesterol or triglycerides, Lp(a) is almost entirely determined by your genetics, and elevated levels can significantly increase your risk of heart attack, stroke, and aortic valve disease, even if the rest of your cholesterol panel looks normal.
Despite affecting an estimated 1 in 5 people worldwide, Lp(a) is rarely included in routine bloodwork. Here’s what you need to know.
What Does Lp(a) Do in the Body?
Lp(a) is a type of LDL particle with an additional protein called apolipoprotein(a) attached to it. This extra protein makes Lp(a) uniquely harmful in two ways:
– It accelerates plaque buildup in your arteries, contributing to atherosclerosis
– It interferes with your body’s ability to dissolve blood clots, because apolipoprotein(a) is structurally similar to plasminogen — a natural clot-dissolving protein
This combination of plaque promotion and impaired clot breakdown is why elevated Lp(a) is considered an independent risk factor for cardiovascular disease — meaning it increases risk regardless of your other cholesterol numbers.
How Common Is Elevated Lp(a)?
Approximately 20% of the global population has elevated Lp(a) levels. Because Lp(a) is genetically determined, levels are relatively stable throughout life and are not significantly affected by diet, exercise, or most conventional cholesterol-lowering medications, including statins.
Why Isn’t Lp(a) Routinely Tested?
There are several reasons Lp(a) testing hasn’t become standard practice:
– Lack of awareness: Many conventional practitioners were not trained to test for or manage Lp(a)
– Limited pharmaceutical options: Until recently, there were no FDA-approved medications specifically targeting Lp(a), which reduced the perceived clinical utility of testing
– Insurance coverage variability: Some insurance plans don’t cover the test, though this is changing
However, major cardiology organizations now recommend that every adult have Lp(a) measured at least once in their lifetime to assess inherited cardiovascular risk.
What Is a Normal Lp(a) Level?
– Desirable: Below 30 mg/dL (or below 75 nmol/L)
– Elevated: 30–50 mg/dL (75–125 nmol/L)
– High risk: Above 50 mg/dL (above 125 nmol/L)
It’s important to note that Lp(a) is measured in two different units depending on the lab, and these are not directly interchangeable. Always confirm which unit your lab uses.
Can Lp(a) Be Lowered?
This is where integrative and naturopathic medicine offers unique value. While lifestyle changes alone have minimal impact on Lp(a), several evidence-based strategies can help:
Niacin (Vitamin B3): High-dose niacin (1,000–2,000 mg/day) can reduce Lp(a) by 20–30%. However, it requires medical supervision due to potential side effects including flushing, liver enzyme elevation, and blood sugar changes.
Hormone replacement therapy: In postmenopausal women, estrogen therapy has been shown to reduce Lp(a) by approximately 20–25%. This is one of the most consistent effects of menopausal hormone therapy and may be particularly relevant for women with elevated Lp(a) who are also experiencing menopausal symptoms.
PCSK9 inhibitors: These injectable medications (evolocumab, alirocumab) can reduce Lp(a) by 20–30% and are sometimes used in high-risk patients.
Emerging therapies: New RNA-based therapies specifically targeting Lp(a) production in the liver are currently in late-stage clinical trials and may become available in the coming years, with reductions of up to 90% reported in trials.
A Naturopathic Approach to Cardiovascular Risk With Elevated Lp(a)
When Lp(a) is elevated, the overall strategy shifts toward aggressively managing every other modifiable risk factor to reduce total cardiovascular burden:
– Optimize LDL cholesterol and triglycerides through diet, targeted supplementation, and medication if needed
– Address inflammation: Chronic inflammation amplifies the damage caused by Lp(a). Anti-inflammatory nutrition, omega-3 fatty acids, and targeted botanicals can help
– Support vascular health: Nutrients like CoQ10, magnesium, and vitamin K2 support arterial flexibility and endothelial function
– Monitor subclinical atherosclerosis: A coronary artery calcium (CAC) score can help determine whether elevated Lp(a) has already contributed to plaque development, guiding the intensity of treatment
– Assess hormonal status: For perimenopausal and postmenopausal women, hormone therapy may serve double duty — managing menopausal symptoms while lowering Lp(a)
Should You Get Tested?
Consider Lp(a) testing if you have:
– A family history of early heart attack or stroke (before age 55 in men, 65 in women)
– A personal history of cardiovascular disease despite normal cholesterol
– Elevated coronary artery calcium score without traditional risk factors
– A family history of elevated Lp(a)
– Aortic valve stenosis, especially at a younger age
Testing requires a simple blood draw and is increasingly covered by insurance, especially when there is a family history of premature cardiovascular disease.
Take the Next Step
Understanding your Lp(a) level is one of the most impactful things you can do for long-term heart health. If you’re concerned about your cardiovascular risk or want a comprehensive assessment that goes beyond standard cholesterol testing, book a consultation to discuss personalized testing and an integrative prevention plan.
