"This report has moved me beyond guesswork and provided a personalized strategy for aging well."

The Challenge

Like many people invested in their long-term health, Casey was already doing the right things — eating well, staying proactive, and thinking ahead. But proactive isn't the same as precise. Without knowing which genetic variants were actually at play in her body, her longevity strategy was built on general advice rather than her unique biology. She needed a roadmap, not a brochure.

What the Test Revealed

Casey's PlexusDx Longevity & Healthy Aging Genetic Test surfaced several significant findings. Her results showed a genetic predisposition for higher LDL cholesterol and elevated ACE enzyme activity — both relevant to cardiovascular health and how her body manages circulatory function. Beyond that, her report identified variants in two longevity-associated genes: FOXO3, linked to cellular aging and stress resilience, and KL (Klotho), associated with aging markers and kidney-cardiovascular function. Her results also flagged her SOD2 gene, which influences mitochondrial antioxidant defense and cellular energy production.

What Changed

Casey didn't wait. After reviewing her results in the PlexusDx Results Portal, she made targeted, specific adjustments:

  • Restructured her meal plan to reduce saturated fat intake and prioritize monounsaturated fats — particularly olive oil — to better support her cardiovascular profile
  • Added CoQ10 to support mitochondrial function in response to her SOD2 findings
  • Incorporated B vitamins to assist mitochondrial energy pathways
  • Built a proactive longevity routine grounded in her FOXO3 and KL variant data — not general anti-aging advice

The Outcome

The most immediate and noticeable result: more consistent energy throughout the day. Casey attributes this directly to implementing the mitochondrial support recommendations from her report. But the deeper outcome is strategic — she now has a personalized, genetically-grounded framework for aging well that she can revisit and build on over time.

In Her Own Words

"The insights from my PlexusDx report have been incredibly eye-opening, particularly regarding my cardiovascular profile and cellular aging markers. After seeing my genetic predisposition for higher LDL and ACE enzyme activity, I've adjusted my meal plans to be much more mindful of saturated fats and have prioritized monounsaturated fats like olive oil to better support my heart health. I was also encouraged to learn about my FOXO3 and KL variants, which give me a concrete reason to stay proactive with my longevity routine. Since implementing the recommended mitochondrial supports, such as CoQ10 and B vitamins to assist my SOD2 enzyme function, I've noticed a more consistent level of energy throughout the day. This report has moved me beyond guesswork and provided a personalized strategy for aging well."

Frequently Asked Questions

What genetic variants are associated with cardiovascular health?

Several genes influence how your body manages cardiovascular function, including variants that affect LDL cholesterol regulation, ACE enzyme activity, and blood pressure response. The PlexusDx Longevity & Healthy Aging Genetic Test screens for variants in these pathways, providing insights into your genetic predispositions so you and your healthcare provider can make more informed decisions about diet, lifestyle, and supplementation.

What is the FOXO3 gene and why does it matter for longevity?

FOXO3 is one of the most studied genes in longevity research. Variants in FOXO3 are associated with cellular stress resilience, DNA repair efficiency, and lifespan across multiple human populations. Understanding your FOXO3 status gives you a concrete genetic basis for prioritizing longevity-focused habits — rather than relying on general age-based recommendations that may not reflect your biology.

Can a genetic test guide supplement choices for heart and mitochondrial health?

Yes — when the test is designed to surface actionable insights, not just raw data. The PlexusDx Longevity & Healthy Aging Genetic Test identifies variants like SOD2, which affects mitochondrial antioxidant defense, and provides specific supplement recommendations based on your results. Casey's report highlighted CoQ10 and B vitamins as targeted mitochondrial supports — recommendations personalized to her genetic profile, not a general wellness checklist.
