At first glance, the world of supplements can feel like a jungle—loud labels, hyped ingredients, and promises that aren’t delivered. But every so often, a voice cuts through the noise. Not just loud, but clear. Not just selling, but sharing. That’s the voice of Dr. Keith C. Ellis, the founder of Science-Driven Supplements, a brand that—true to its name—delivers honest, evidence-based formulations born from necessity, persistence, and personal experience.

This isn’t just a brand story. It’s a recovery story, a human story, a story about Long Covid, resilience, and the intersection of hardcore biochemistry and good old-fashioned human intuition.

And right at the center? Two standout products: CircuGuard and Oxy Boost—innovative, plant-powered solutions designed to optimize circulation, oxygen delivery, and cellular energy when your body needs it most.

Let’s journey through the science, the soul, and the story behind these powerful formulas.

When Science Meets Suffering: A Founder’s Catalyst

Dr. Keith C. Ellis, PhD, isn’t your average supplement founder. With a background steeped in pharmaceutical science, immunology, and chronic disease research, he was already well-versed in molecular mechanisms and clinical outcomes. But it wasn’t until Long Covid hit him personally that his theoretical knowledge had to turn into something practical. Something urgent.

For months, he dealt with crushing fatigue, inflammation, brain fog, and poor circulation. The kind of symptoms that make everyday life feel like running a marathon in molasses. And what the traditional medical system offered didn’t cut it.

So, what did he do? He turned to the lab—not to patent another synthetic drug, but to develop a natural answer that worked.

CircuGuard and Oxy Boost weren’t born in a boardroom. They were born in the fog of recovery, guided by published research, trial-and-error experiments, and a fierce desire to heal.

CircuGuard: More Than Just Blood Flow

Let’s start with CircuGuard, the flagship formula born from Dr. Ellis’s deep dive into vascular biology, natural COX inhibition, and cytokine modulation.

For most people, “circulation” makes them think of cold hands and feet, or maybe heart health. But for people recovering from inflammatory conditions—Long Covid included—blood flow is everything. It means oxygen reaches your cells. It means toxins are cleared. It means your body can do the hard work of healing.

So, What’s Inside CircuGuard?

This isn’t a garden-variety circulation blend. It’s a scientific symphony of:

• Hesperidin and Diosmin: Powerful citrus bioflavonoids are known for improving venous tone and reducing oxidative stress in blood vessels.

• Nattokinase: A natural fibrinolytic enzyme that supports healthy blood flow and prevents microclot formation (a serious issue in post-viral syndromes).

• Boswellia: A COX-2 inhibitor with potent anti-inflammatory properties.

• Ginger + Pine Bark Extract (Pycnogenol): Nature’s vascular tune-up crew, known to enhance nitric oxide production and vessel flexibility.

• Butcher’s Broom and Horse Chestnut Extract: Time-tested ingredients for supporting vein health and reducing swelling.

It’s like a spa day for your circulatory system—but molecularly targeted and research-backed.

For Dr. Ellis, CircuGuard wasn’t just a supplement. It was a lifeline. A way to regain clarity, stamina, and that lost feeling of “normal” that chronic fatigue so cruelly strips away.

The Story of CircuGuard: A Four-Part Substack Masterpiece

The development of CircuGuard didn’t happen overnight—and Dr. Ellis chronicled every stage of the journey on his Substack. In a gripping four-part series, he walks readers through the detective work that went into the formula.

From investigating natural COX inhibitors (Part 2) to dissecting which herbal extracts were absorbed in the human gut (Part 3), his posts read like a medical thriller, with ingredients like quercetin, resveratrol, and curcumin playing the role of underdog heroes.

But this wasn’t just about science for science’s sake. It was about real-world recovery, shared transparently and humbly, so others navigating the fog of post-viral syndromes could benefit, too.

Oxy Boost: Your Cellular Power-Up

If CircuGuard is the plumbing crew—making sure everything flows smoothly—then Oxy Boost is the electric grid, powering up your mitochondria so you can feel alive again. Inspired by his battle with breathlessness and fatigue, Dr. Ellis developed Oxy Boost to target the very core of human energy: oxygen utilization and mitochondrial efficiency.

At its heart is one superstar: organic beetroot powder, nature’s nitric oxide booster. But this isn’t just any beetroot.

Thanks to its high nitrate content, the beetroot in Oxy Boost supports the body’s natural ability to widen blood vessels, enhance oxygen delivery, and reduce the oxygen cost of exercise. In simple terms? You can breathe better, move better, and recover faster.

But wait—there’s more:

• Cordyceps mushroom extract: Used for centuries in Traditional Chinese Medicine, cordyceps supports ATP production and lung capacity.

• Mango extract (Mangiferin): A unique polyphenol with anti-inflammatory and antioxidant effects, especially useful in combating fatigue.

• Vitamin C and Magnesium: Supporting roles in cellular respiration, antioxidant recycling, and overall energy metabolism.

Oxy Boost is essentially the “pre-workout” for people who aren’t gym rats but still want to climb stairs without collapsing. It’s for post-viral warriors, parents, professionals, and anyone who feels like their energy account is always overdrawn.

Designed for Real Recovery

There’s something refreshingly honest about how Science-Driven Supplements is built. These products weren’t made for Instagram. They were made for healing. For getting your life back.

Dr. Ellis didn’t choose trendy ingredients or throw in random “superfoods” to impress. He reverse-engineered the formulas from the pathophysiology of Long Covid and chronic inflammation—and used only compounds with measurable bioavailability, strong mechanistic plausibility, and a track record of clinical efficacy.

The result? Supplements that do what they say on the label.

And because Dr. Ellis shares the “why” and “how” behind every decision in his Substack articles, customers can go beyond trust—they can understand.

A Brand Built on Brains, Integrity, and Empathy

Science-Driven Supplements don’t try to be flashy. It doesn’t need to be. When you’re struggling with fatigue, brain fog, or unexplained inflammation, what you want isn’t hype. You want help. Clarity. Solutions.

This brand gives you that.

Dr. Ellis’s Substack is packed with in-depth breakdowns, real user stories, and transparent explanations of how the body works and how to support it. His social media presence isn’t about selfies—it’s about science. And his website? Straightforward, research-backed, and easy to navigate.

It’s a rare kind of brand these days. One that values truth over trendiness, and results over rhetoric.

Community-Driven, Recovery-Focused

What’s truly special about Science-Driven Supplements is its growing community of thinkers, doers, and survivors. From PhDs to parents, athletes to educators, customers aren’t just taking pills—they’re part of a movement toward smarter, safer self-care.

They’re learning. Healing. Sharing.

CircuGuard and Oxy Boost are just the beginning. Dr. Ellis’s long-term vision includes expanding into other recovery-focused areas—always grounded in real clinical mechanisms, not fairy dust marketing.

Because, at the end of the day, Science-Driven Supplements isn’t just about feeling better. It’s about understanding why you feel better. And that’s power.

Final Word: Not Your Average Supplement Story

CircuGuard and Oxy Boost may sound like superhero names—and honestly, they kind of are. But they’re not magic bullets or miracle cures. They’re carefully designed tools in the hands of people ready to fight for their health, guided by someone who’s fought that battle himself.

Dr. Ellis didn’t just create a product. He created a blueprint. A rallying cry. A chance for people to take control of their recovery in a world that too often leaves them in the dark.

So, whether you’re navigating Long Covid, chronic fatigue, or just the daily grind of modern life, Science-Driven Supplements offers more than supplements.

It offers hope, backed by hard data, delivered with heart.
