Heart Health

A standard lipid panel gives you four numbers: total cholesterol, LDL, HDL, and triglycerides. That's a start. It's not enough.

We run an expanded cardiovascular panel that looks at the markers research has linked most closely to actual heart disease risk.

Apolipoprotein B (ApoB). This is the protein responsible for plaque formation in your arteries. It's a better predictor of cardiovascular events than LDL alone. Two people can have the same LDL number but very different ApoB levels, and therefore very different risks.

Lipoprotein(a), or Lp(a). This is a genetically determined marker that is more closely associated with cardiovascular disease than LDL or total cholesterol. Most conventional doctors never test it. If yours is elevated, it changes how aggressively we approach prevention.

LDL particle size and number. Not all LDL is the same. Small, dense LDL particles are far more likely to contribute to plaque formation than large, buoyant ones. When insulin resistance increases, VLDL production rises and LDL particles get smaller. This is where the real danger lives, and a standard panel misses it entirely.

High-sensitivity CRP (hsCRP). This measures systemic inflammation. Inflammation damages the endothelium (the single-cell lining inside your blood vessels). Damaged endothelium impairs nitric oxide production, which reduces blood flow and creates the conditions for plaque to form. You can have perfect cholesterol and still be at high risk if your inflammatory markers are elevated.

Fasting insulin and HbA1c. Insulin resistance is one of the most common drivers of both high cholesterol and high blood pressure. When insulin function breaks down, sodium retention increases, fluid expands, and blood pressure rises. Meanwhile, VLDL production increases and LDL particles shrink. These two markers catch the problem years before a diabetes diagnosis.

Homocysteine. An amino acid that, when elevated, damages blood vessel walls and increases clotting risk. It's related to B vitamin status and is treatable once identified.

Vitamin D, ferritin, B12. Nutrient deficiencies affect cardiovascular function. Low vitamin D is linked to increased cardiovascular risk. Low B12 and folate allow homocysteine to climb. Low ferritin affects energy and cardiac output.

Thyroid panel and sex hormones. Thyroid dysfunction affects cholesterol metabolism directly. Low testosterone in men is associated with higher cardiovascular risk. Estrogen and progesterone decline in women increases heart disease risk after menopause. These connections are well-established in the research, and almost never tested together in conventional care.

Cardiac calcium score CT scan (when indicated). This imaging study shows whether any plaque has actually formed in your coronary arteries. A score of zero means no plaque, regardless of what your LDL says. It's one of the most useful tools for assessing real cardiovascular risk, and we order it when the clinical picture warrants it.

Magnesium is one of the most important minerals for cardiovascular function, and most people in Maine (and across the U.S.) are not getting enough. It plays a direct role in blood pressure regulation, heart rhythm stability, blood vessel relaxation, and insulin sensitivity. Low magnesium is associated with higher cardiovascular risk, and it is rarely tested on a standard blood panel.

Not all magnesium supplements are the same. The form matters.

Magnesium glycinate is the most commonly recommended form for overall cardiovascular and nervous system support. It is well-absorbed and less likely to cause digestive issues than other forms. For patients dealing with stress, poor sleep, or muscle tension alongside cardiovascular concerns, glycinate covers multiple bases.

Magnesium taurate pairs magnesium with the amino acid taurine, which has its own cardiovascular benefits. Research links taurine to improved blood pressure and heart rhythm regulation. This form is often recommended specifically for patients focused on heart health.

Magnesium citrate is well-absorbed but can cause loose stools at higher doses. It works for patients who also deal with constipation, but it is not the first choice for cardiovascular-specific supplementation.

Magnesium oxide is the cheapest form and the most commonly found on store shelves. It is also the most poorly absorbed. Most of it passes through your system without being utilized. If your current supplement is magnesium oxide, you are likely not getting the benefit you think you are.

At Med Matrix, your provider tests your magnesium level as part of the initial 80+ biomarker panel and recommends the right form and dose based on your labs, your symptoms, and your cardiovascular risk profile. Supplementation is one piece of a broader protocol that includes metabolic optimization, inflammation reduction, and lifestyle changes.

Supplements can support cardiovascular function, but only when they are chosen based on your labs rather than a marketing label. Taking a generic "heart health" supplement without knowing your levels is guesswork. Some of the most commonly recommended supplements for cardiovascular support include:

Omega-3 fatty acids (EPA and DHA). Reduce triglycerides, lower inflammation, and support endothelial function. Quality matters. Your provider will recommend a dose based on your inflammatory markers and lipid panel. Many patients benefit from 2,000 mg or more per day.

Coenzyme Q10 (CoQ10). Critical for cellular energy production and muscle function. Statins block CoQ10 synthesis, which is why many patients on statins experience fatigue and muscle pain. If you are on a statin, CoQ10 supplementation is often necessary to replace what the medication depletes.

Vitamin D. Low vitamin D is linked to increased cardiovascular risk, and deficiency is common in New England. Your provider targets levels between 50 and 80 ng/mL, well above the 30 ng/mL threshold most conventional labs consider "normal."

Magnesium. Supports blood pressure regulation, heart rhythm, and insulin sensitivity. Most patients benefit from magnesium glycinate or magnesium taurate, depending on their specific profile.

B vitamins (B12, folate, B6). Help regulate homocysteine levels. Elevated homocysteine damages blood vessel walls and increases clotting risk. B vitamin status is easy to test and easy to correct.

Fiber. Not a supplement in the traditional sense, but increased dietary fiber (especially soluble fiber) improves cholesterol metabolism and triggers natural GLP-1 release. Cold-cooked potatoes, for example, produce resistant starch that feeds beneficial gut bacteria and supports metabolic function.

The key is testing first, supplementing second. Your provider at Med Matrix will recommend specific supplements, forms, and doses based on your 80+ biomarker panel results. We have treated over 3,000 patients and maintain a 4.9-star rating across 150+ Google reviews.
