## Features

- ELITE NITRIC OXIDE PRECURSOR: Stop settling for low-dose Arginine. Heart of Steel delivers a massive 1000mg of L-Citrulline, the most bioavailable precursor for Nitric Oxide production. This "Stage-1" vasodilator ensures your arteries remain flexible and open, promoting healthy blood flow and optimal blood pressure levels year-round.
- ADVANCED CARDIOVASCULAR PROTECTION: While "common" brands stop at amino acids, we integrated 150mg of CoQ10 and 200mg of Resveratrol. This potent antioxidant duo works at the cellular level to protect your heart from oxidative stress and inflammation, providing a "Steel Shield" for your most vital organ.
- ALL-DAY ENERGY & MENTAL FOCUS: Experience a surge in vitality without the jitters. By optimizing circulation to the brain and muscles, our blend of Ginkgo Biloba and Panax Ginseng enhances oxygen delivery. This results in sharper mental clarity and sustained physical energy, making it the premier nitric oxide supplements for men and active adults seeking a natural edge.
- THERMODYNAMIC CIRCULATION BLEND: Our unique addition of Capsaicin acts as a natural "pump" for your vascular system. This helps maintain warmth in extremities and supports efficient nutrient transport. When combined with our l-arginine l citrulline supplement complex, it ensures every cell in your body is nourished, revitalized, and performing at its peak.
- RECOVERY & ANTI-INFLAMMATORY SUPPORT: Combat the silent wear and tear of aging. With 150mg of Quercetin and Rhodiola Rosea, Heart of Steel modulates the body's inflammatory response. It serves as one of the most comprehensive heart health supplements available, protecting your vascular walls while acting as a potent nitric oxide supplement for total body recovery.
- THE 60-DAY GOLD STANDARD: Heart health is a marathon, not a sprint. While many feel an energy lift within days, the structural cardiovascular benefits of our l-arginine for men and women peak after 30 to 60 days of consistent use. Our 120-capsule bottle provides a full 2-month supply of the most advanced nitric oxide supplements for men formula on the market.
