Cardiologist Dr. Sarah Chen: "The Biggest Risk Factor for Heart Disease Isn't Your Cholesterol — It's Your Birthday"

Dr. Sarah Chen has spent her career studying what actually drives cardiovascular risk as we age.

Most people track one number, and manage it closely. But according to cardiologist Dr. Sarah Chen, that number was never the biggest risk factor to begin with. We sat down with her to talk about what actually is.

Q: That's a striking way to put it. What do you mean?

- I mean it literally. After 40, your risk of cardiovascular disease roughly doubles every decade. Not because of any one number, because of aging itself. Most people manage the number in front of them and never address the thing actually driving it.

Q: So what is aging actually doing, mechanically?

- A few things happen at once. Arteries naturally become stiffer over time. Blood vessels lose elasticity. Endothelial function, which is how well your vessels regulate blood flow, declines. None of that shows up on a cholesterol panel, but all of it raises your risk.

Arteries naturally stiffen and lose elasticity with age, independent of what a cholesterol panel shows.

Q: Is that separate from something like inflammation?

- It's related. There's a term researchers use, "inflammaging," chronic low-grade inflammation that increases with age and is linked to cardiovascular disease, cognitive decline, and frailty. It's one of the reasons aging isn't just a number, it's an active process happening in the background.

Q: You mentioned biological age earlier. Is that different from just getting older?

- Genuinely different, and this is the part more people should know. Nearly 1 in 5 adults show signs of accelerated aging in at least one organ, often without any symptoms. Biological age often predicts disease risk better than the number on your birthday cake. Two people can be the same chronological age and be aging very differently on the inside.

Q: Is that why you started thinking about a protocol instead of a single supplement?

- Exactly. Aging affects multiple systems at once, so it doesn't make sense to address it with one ingredient. The Heart Health Protocol supports three separate mechanisms tied to cardiovascular aging specifically. Nattokinase supports circulation and vascular function, both of which decline with age. Citrus Bergamot is rich in polyphenols that help combat oxidative stress, one of the recognized hallmarks of biological aging. CoQ10 addresses something specific: levels decline naturally as we age, which reduces cellular energy production and antioxidant defenses. Three mechanisms, three ingredients, because aging isn't a single-pathway problem.

Q: Can aging actually be slowed down, or is this just about managing the symptoms?

- That's the question everyone eventually asks, and there's real research on it, not just theory. The CALERIE trial is the one I point to most. Participants who reduced calorie intake by about 12% for two years slowed their biological aging by 2 to 3%. That sounds small until you look at what researchers estimate it translates to: a 10 to 15% lower risk of death over the following 10 to 15 years.

Q: That's a pretty significant outcome from a fairly modest change.

- That's exactly the point. Small, sustained changes to the underlying biology of aging can meaningfully shift long-term risk, more than most people assume. Nobody needs to overhaul their entire life. The body responds to consistent, targeted support.

Q: Does that logic apply to what's in the Heart Health Protocol specifically?

- It's the same principle. CoQ10 supplementation has been shown to improve mitochondrial function and reduce markers of oxidative stress in older adults, addressing something that naturally declines with age rather than trying to reverse it after the fact. Patients often notice steadier energy within three to four weeks, that's the CoQ10. The vascular and antioxidant support from Nattokinase and Citrus Bergamot builds more gradually, generally over two to three months, similar to how the research on aging itself plays out over a sustained period, not overnight.

What the research actually shows

Rather than one big number, here's what's actually been documented about aging and each ingredient's role in it:

• Age itself: More than 80% of adults 65 and older live with at least one chronic condition, and many have two or more. Age is considered the single greatest risk factor for heart disease, cancer, type 2 diabetes, Alzheimer's, and stroke, not just a background variable.
• CoQ10: Levels decline naturally with age, reducing both cellular energy production and antioxidant defenses. Supplementation has been shown to improve mitochondrial function and reduce markers of oxidative stress in older adults.
• Citrus Bergamot: Rich in polyphenols shown to help combat oxidative stress, one of the recognized biological hallmarks of aging.
• Nattokinase: Supports healthy circulation and vascular function, both of which decline with age and directly contribute to cardiovascular aging.

*Individual results may vary. These statistics reflect research on aging mechanisms and ingredient effects broadly, not a guarantee of results for any individual.

Age is the #1 risk factor for heart disease, stroke, and dementia.

No Blends. No Guesswork. Just What's on the Label.

Q: With so many products marketed toward aging and longevity, how do you tell what's actually worth taking?

- Honestly, most of it is noise. Proprietary blends that hide how much of anything you're actually getting, vague claims about "anti-aging" with nothing specific behind them. The research on aging is real, but a lot of the products built around it aren't held to that same standard.

Q: What should someone actually look for?

- Full-strength, single-ingredient dosing, not a blend where you can't tell what you're getting enough of. Each ingredient in this protocol is dosed at the level that's actually been studied for what it does, not a fraction of it dressed up in marketing language. If a product won't tell you exactly how much of an ingredient is in it, that's usually the answer to how much is actually in it.

Why One Ingredient Was Never Going to Cover Aging

Q: Couldn't someone get similar benefits just taking CoQ10 on its own? It seems to get the most attention.

- They could get part of the benefit, and CoQ10 alone is genuinely useful. But aging isn't a single-pathway problem, it's multiple systems declining at overlapping but different rates. If you only address cellular energy, you're leaving vascular health and oxidative stress completely unaddressed. Someone doing that might feel more energetic and still be accumulating risk elsewhere without realizing it.

Q: Is that the actual case for a protocol instead of picking one ingredient that sounds the most relevant?

- That's exactly it. It's less about any one ingredient being insufficient, and more about aging itself not being one process. Cellular energy, vascular function, oxidative stress, these move somewhat independently. A protocol that addresses all three is working with how aging actually happens in the body, rather than treating it like it has a single lever.

From Reacting to Aging to Actively Supporting It

Q: A lot of people just accept getting older and figure they'll deal with problems as they show up. What would you say to that?

- That's the default, and it's understandable, aging feels passive because it happens gradually. But there's a real difference between waiting to react to something and actively supporting the systems behind it before there's a problem to react to. Most people don't think about vascular health or oxidative stress until something forces them to. A protocol asks something different, it's a daily habit aimed at what's actually happening, not a response to a diagnosis.

Q: Does that change how people think about themselves, not just their health?

- It's the shift I see most often, honestly. People stop thinking of themselves as waiting for something to go wrong and start thinking of themselves as someone who's already doing something about it. That's a meaningful difference in how people carry themselves day to day, not just a health outcome.

Real Results From People Taking Aging Seriously

These are the kinds of results I'd expect from people who stop reacting to aging and start actively supporting it. The birthday number was never the real risk factor, what happens underneath it is. — Dr. Sarah Chen
