Hi, I’m Stephen.
We started onlyone™ Heart because after my heart attack, I did everything I was supposed to do. I cleaned up my diet. I took my statin every day (still do). I stayed active. But my energy wasn’t steady. Workouts took longer to recover from. I felt more tired than I expected for someone trying to do everything right.
And I wanted to be here, fully here, for my wife, my kids, my family.
Most adults managing cardiovascular health are juggling multiple supplements, inconsistent routines, and a lot of conflicting information.

✓ Muscle performance during physical activity and recovery*
✓ The body’s natural antioxidant defense network*
✓ Protecting healthy cells from free radical damage*
✓ A balanced, healthy inflammatory response to promote long-term cardiovascular wellness *
✓ Healthy homocysteine metabolism for long term cardiovascular wellness*
✓ Methylation cycles for arterial health and mental clarity*
✓ Blood pressure levels already within the normal range*
✓ Proper calcium utilization for vascular wellness and bone strength*
✓ Healthy stress and sleep cycles*

"My patients frequently ask about nutritional support when managing cardiovascular health. A formulation that combines commonly discussed ingredients in the scientific literature such as CoQ10, magnesium, and B vitamins into a single product simplifies supplementation and may ease pill burden that many of our patients deal with."
- Dr. Danny Eapen, Board Certified - Cardiologist

onlyone™ Heart was built to complement your prescribed therapy, not compete with it.

"There's a real difference between a kitchen-sink supplement and one built around evidence. The nutrients in this formula are the ones I find myself discussing most often with cardiac patients, delivered in forms the body can actually absorb and use."
— Julia Zumpano, Registered Dietician
This is how simple it should be.
Still have questions? We’ve got honest answers.Onlyone™ Heart is designed to work alongside, not replace or interfere with, your statin therapy. That said, if you have specific concerns, always run it by your cardiologist first. We’re pro-doctor, not a substitute for one.
Also, always consult with your physician before starting any new supplement regimen, particularly if you are taking other prescription medications. If you are on a blood thinner such as Warfarin, please consult your doctor before taking onlyone™ Heart, particularly regarding the Vitamin K2 content. Our formulation features MK-7 not the typical K1 that has known interactions with coumadin/Warfarin, but it's worth making sure your doctor feels comfortable with you taking it.*
Ubiquinol is the active, reduced form of CoQ10. Research suggests it’s better absorbed*, particularly for people over 40 whose bodies become less efficient at converting ubiquinone to the usable form*. It costs more to use. We use it anyway.
Every person is different, onlyone™ Heart is a dietary supplement, not a drug, and we don’t make specific outcome promises. Most nutritional supplements take several weeks to build up in your system. They support normal body functions over time rather than delivering an immediate effect. We recommend giving it at least 60 -90 days, which is why we offer a 60-day satisfaction guarantee.
Methylation is one of your body's most important behind-the-scenes processes — a constant chemical hand-off that happens billions of times a second, helping your body do everything from building DNA to processing certain compounds and keeping key systems running smoothly. B vitamins (B6, B9/folate, and B12) are essential helpers in this process.
Homocysteine is an amino acid your body produces normally as a byproduct of metabolizing methionine (an amino acid from protein in your diet). It's not meant to accumulate; your body continuously clears it through two pathways, and methylation is the main one.
Adequate active B vitamins keep the methylation pathway running, which is how the body maintains homocysteine in its normal range.

Contraindication Statement
Always consult with your physician before starting any new supplement regimen, particularly if you are taking prescription medications. If you are on a blood thinner such as Warfarin, please consult your doctor before taking onlyone™ Heart, particularly regarding the Vitamin K2 content.
