About
Cardio Miracle was founded in 2015 by John Hewlett following a personal health crisis—and a powerful mission: to help people take control of their long-term health. Rooted in nitric oxide research and backed by a growing body of peer-reviewed studies, the company blends over 50 natural, bioavailable ingredients to support heart health, circulation, energy, and immune function.
What began as a personal journey has become a purpose-driven brand trusted by wellness advocates, medical professionals, and especially older adults seeking to improve and maintain their health over time. For their customers, daily, consistent use is essential—and so is making that routine easy to maintain.
That’s why subscriptions aren’t just a business model for Cardio Miracle—they’re a critical part of the customer experience. Automatic deliveries ensure customers never miss a dose, removing the friction of reordering and helping people stay on track with their wellness goals. Recharge powers that experience, giving Cardio Miracle the tools to support long-term health outcomes while creating operational stability to invest in research, partnerships, and mission-driven growth.

At Cardio Miracle, subscriptions aren't just a small part of the business; they drive it. Recurring revenue funds everything from day-to-day operations to ambitious marketing experiments like sponsoring local wellness events and public speakers. With a loyal customer base, many of whom are older and prefer consistency, CardioMiracle sees subscriptions as the most sustainable path to long-term growth that makes their customers' lives easier and also provides a more predictable revenue source.
It’s so convenient to have everything in one place. These tools have saved us time, money, and frustration, and they’ve been set-it-and-forget-it solutions that have driven results for us.

Challenge
Too many tools, not enough impact
For CardioMiracle’s customer base, many of whom prioritize ease and routine, any friction at the point of purchase reduced the likelihood of choosing a subscription. With their previous setup, subscription upgrade paths weren’t visible across the journey. And for an audience that appreciates straightforward, easy-to-understand options, that lack of clarity made a meaningful difference.
That disconnect threatened the heart of CardioMiracle’s mission: helping people take control of their long-term health through consistent daily use. Without intuitive subscription options embedded throughout the journey, the team couldn’t confidently guide customers toward the experience that delivers real, lasting results.
Managing multiple platforms also slowed down the team and introduced unnecessary overhead. For a lean brand powered by recurring revenue, CardioMiracle needed fewer tools, not more, and a subscription-first system that made it effortless for customers to commit to a healthier routine from day one.

Solution
Upsells at every touchpoint, powered by a unified platform
When Recharge released native upsell tools—covering the product page, cart, and checkout—CardioMiracle made the switch. The tools were fully integrated into Recharge, came included with their plan, eliminating the need to spend on third-party apps, and were built for subscription-first businesses like CardioMiracle. The best part? These tools took just a few minutes to set up and drive meaningful results.
Now, CardioMiracle has a simplified tech stack and a fully optimized subscription journey. At every key touchpoint—PDP, cart, and checkout—customers are shown clear, easy-to-understand subscription benefits, with upgrade paths that are as simple as a single click.
Results
More long-lasting customers, greater lifetime value
CardioMiracle didn’t change their acquisition strategy. They didn’t introduce new promotions or revamp their funnel. They simply activated Recharge’s upsell tools—and let them work.
The impact: a 23.63% increase in subscription sales, with the cart alone responsible for 13.68% of the lift.
For CardioMiracle, subscribers aren’t just a revenue stream—they’re long-term users whose habits align with the brand’s mission of promoting consistent, daily health routines. Many are older adults who value simplicity and stick with what works. Once they subscribe, they tend to stay, generating 3x more lifetime value than one-time buyers, with some worth up to 21x more over time. These aren’t casual customers—they’re loyal advocates whose sustained usage drives both predictable revenue and real health outcomes.
With Recharge’s upsell tools, CardioMiracle has turned every key touchpoint into a straightforward subscription upgrade opportunity—no third-party tools, no added costs, and no disruption to the customer experience. More importantly, it’s helping customers stay consistent with their health goals, while fueling a mission-driven business built to make a lasting impact.
“Subscriptions are the lifeblood of our business. Everything we do—all of our fun, creative ideas is funded by the recurring revenue we get.”
