Heart of Steel
The three-pillar approach to bloodflow optimization.
Most cardiovascular supplements stop at one ingredient and call it a day. Heart of Steel doesn't. Because real circulation isn't one thing - it's a system. The body needs to make nitric oxide, keep vessels open, and protect the cells lining them. Miss a step and the rest underperform.
We built Heart of Steel to address all three.
Pillar 1 - Nitric Oxide Production
Nitric oxide is the molecule your blood vessels use to dilate. More NO means better circulation, better pumps, and lower vascular resistance. Two ingredients in Heart of Steel target this pathway directly:
-
L-Citrulline - 1,000 mg - the most bioavailable precursor to L-Arginine and a clinically studied driver of NO production
-
L-Arginine HCl - 400 mg - the direct substrate for nitric oxide synthase
Full doses of each. Listed on the label.
Pillar 2 - Vasodilation & Circulation
Producing NO is one half of the equation. Keeping vessels open and blood moving is the other. These ingredients support healthy blood flow, vasodilation, and microcirculation:
-
Ginkgo Biloba - 200 mg of 10:1 extract - studied for its role in peripheral and cerebral circulation
-
Coleus Forskohlii - 100 mg of 10% forskolin extract - traditionally used to support vascular tone
-
Capsaicin - 20 mg of 1% extract - supports peripheral blood flow and thermogenesis
Pillar 3 - Cardiovascular Protection
Blood vessels are constantly under oxidative stress. Antioxidants protect endothelial cells and support long-term cardiovascular function. The most overlooked pillar in most cardio formulas:
-
CoQ10 (Ubiquinone) - 200 mg of 99% pure - a foundational antioxidant for mitochondrial and cardiovascular health
-
Resveratrol - 200 mg of 98% extract - studied for endothelial support and antioxidant capacity
-
Quercetin Dihydrate - 200 mg of 95% extract - a flavonoid associated with cardiovascular and circulatory support
What's not in it
-
No proprietary blends. Every dose is on the label.
-
No unnecessary fillers. No artificial colors.
-
No fairy dust. Real doses of every ingredient.
What's behind it
- Manufactured in an FDA-registered, GMP-certified facility
- Every lot third-party tested

Who it's for
Heart of Steel is built for people who already train, already eat well, and want a research-backed formula that supports the cardiovascular system at every level. If you're looking for a stim-loaded pre-workout, this isn't it. If you want a foundational daily formula built on how circulation actually works, you're in the right place.
