The Heart Health Marker Most Women Over 40 Have Never Heard Of (And What to Do About It)

Most heart health conversations start and end with cholesterol. And whilst cholesterol matters, there is a lesser-known cardiovascular marker that research increasingly identifies as a more significant independent risk factor — particularly for women navigating the menopause transition.

It is called lipoprotein(a), or Lp(a), and the chances are your GP has never mentioned it.

What is Lp(a) and why does it matter?

Lp(a) is a type of lipoprotein particle — structurally similar to LDL cholesterol, but with an additional protein called apolipoprotein(a) attached. This structure makes it particularly problematic: it is strongly associated with a higher risk of heart disease, stroke, and aortic valve stenosis, independent of your LDL or total cholesterol levels.

In plain terms, you could have a perfectly normal cholesterol panel and still carry significant cardiovascular risk if your Lp(a) is elevated.

Around 20% of the population carries genetically elevated Lp(a) — and oestrogen decline during perimenopause can increase levels further. A 2024 analysis published in the European Heart Journal found that Lp(a) levels rise meaningfully during the menopause transition, adding to the broader cardiovascular risk shift that occurs in midlife women.

The challenge: Lp(a) is notoriously difficult to lower

Unlike LDL cholesterol, which responds reasonably well to dietary change and statins, Lp(a) is largely genetically determined. Standard lifestyle interventions — eating well, exercising, reducing saturated fat — have minimal impact on Lp(a) levels in most people.

This is what makes recent research around curcumin particularly interesting.

What the research says about curcumin and Lp(a)

A 2024 meta-analysis published in PubMed (PMID 40252824) found that curcumin, when delivered in a highly bioavailable form, significantly reduced Lp(a) levels over just a few months of supplementation.

The researchers identified two key mechanisms. First, curcumin modulates NF-κB signalling — a central pathway in the inflammatory cascade that drives hepatic (liver) production of Lp(a). Second, its antioxidant activity reduces oxidative stress, which independently contributes to cardiovascular risk.

The critical word here is bioavailable. Standard curcumin from turmeric powder is poorly absorbed — studies suggest as little as 1% reaches systemic circulation. The studies showing meaningful Lp(a) reduction used high-bioavailability curcumin formulations, which absorb dramatically better.

Why this matters specifically for perimenopause

The convergence of rising Lp(a) levels during menopause and declining oestrogen-mediated cardioprotection creates a window where targeted nutritional support becomes meaningfully relevant. Oestrogen plays a protective role in cardiovascular health — it supports healthy lipid profiles, vascular flexibility, and inflammatory regulation. As levels decline, all of these functions need additional nutritional scaffolding.

This is not about fear — it is about being informed. Understanding your Lp(a) status, and taking practical steps to support cardiovascular health through the transition, is simply good science applied to a specific life stage.

The 3-in-1 approach: Bio-Avail Omega+ by Adapt Naturals

This is the formulation rationale behind Bio-Avail Omega+ from Adapt Naturals — a supplement I recommend because it combines three clinically targeted actives in two softgels a day, addressing cardiovascular, inflammatory, and cognitive health simultaneously.

The three actives work in complementary ways:

NovaSol® Curcumin (500 mg) — NovaSol is the most bioavailable curcumin form currently on the market, with published absorption data showing it outperforms standard curcumin significantly. This is the form used in studies showing Lp(a) reduction and NF-κB modulation.

Ultra-Pure Fish Oil — EPA 510 mg, DHA 330 mg — EPA and DHA are foundational to cardiovascular and metabolic health. DHA is particularly relevant for cognitive function during perimenopause, when oestrogen-supported neurological processes are under transition.

ThymoQuin™ Black Seed Oil (500 mg) — A standardised black seed oil extract rich in thymoquinone, the active compound associated with joint comfort, cognitive clarity, and mood support. Thymoquinone has its own anti-inflammatory mechanisms, making this a genuinely complementary addition rather than a marketing afterthought.

One verified buyer — Sara, a woman navigating menopause — put it clearly: “It is great to find a supplement that goes beyond just omega-3s and includes extra compounds that really target inflammation and cardiovascular support. It means I can get high-quality support in a single dose, instead of piecing together three different formulations from separate companies.”

Practical steps if you are concerned about Lp(a)

If cardiovascular health is a priority for you during perimenopause — and the research suggests it should be — here is a practical framework:

1. Ask your GP to test Lp(a). It is not included in standard cholesterol panels and you may need to ask specifically. Private testing is also straightforward and relatively affordable.

2. Support the methylation pathway. Homocysteine — elevated when methylation is impaired — is an independent cardiovascular risk marker. B vitamins (particularly B6, B12, and folate) are the primary nutritional levers here.

3. Prioritise omega-3 intake. EPA and DHA support vascular health, reduce triglycerides, and have meaningful anti-inflammatory effects. Food sources (oily fish 2–3 times per week) and supplementation both contribute.

4. Consider bioavailable curcumin. Given the emerging evidence around Lp(a) and NF-κB modulation, a high-bioavailability curcumin supplement is a reasonable addition to a cardiovascular support protocol — particularly where standard dietary curcumin will not reach therapeutic levels.

Bio-Avail Omega+ addresses points three and four in one product, with the addition of ThymoQuin black seed oil for broader inflammatory and cognitive support. You can find it at adaptnaturals.com — use code CHLOE10842 for a discount.

Your heart is not a separate organ to manage independently of your hormones, your gut, or your methylation status. It is part of the same interconnected system — and the perimenopause transition is precisely the moment to start paying attention to all of it.
