Study-Backed to Address Post-Cardiac Symptoms

This formula uses clinically studied amino acids that restore nitric oxide—the molecule your body stopped making after your cardiac event. It targets microvascular dysfunction, residual inflammation, and autonomic imbalance—the root causes your medications can't reach.

🔴 L-Arginine 3,000mg — Direct substrate for nitric oxide production at blood vessel walls. Clinical trials used 9g/day (3,000mg × 3 doses). Improves coronary blood flow reserve by 149% at 6 months. Most supplements use 1,000mg—83% below therapeutic threshold.

🟠 L-Citrulline 2,000mg — Converts to L-arginine in your kidneys with 105% bioavailability (vs 30% for oral arginine). Bypasses the 70% first-pass metabolism that destroys arginine supplements. Provides sustained elevation for hours, not minutes.

🟡 Synergistic Combination — Japanese research proved: 1g citrulline + 1g arginine raises plasma arginine MORE than 2g of either alone. The combination at half-doses exceeds full-dose monotherapy through enzymatic protection and metabolic recycling.

🔵 Clinical-Strength Dosing — Total arginine equivalent: ~7,000mg per serving. Matches cardiovascular trial protocols showing 149% coronary flow improvement, 12% exercise tolerance increase, 23-40% inflammation reduction.

🟢 Targets What Stents Miss — Opens microvessels under 100 micrometers—invisible on angiography, unreachable by procedures. These vessels deliver oxygen directly to heart tissue. When they fail, you get chest pain despite "perfect" stents.

Addresses Residual Inflammatory Risk — 29-60% of post-MI patients maintain high inflammation (hs-CRP ≥2 mg/L) despite statins. Statins reduce inflammation by only 16-37%. Nitric oxide reduces IL-6 by 23-40%—targeting the inflammatory cascade statins can't reach.

Each serving delivers targeted support to open microvessels, calm inflammation, and restore autonomic balance—not just mask symptoms like prescriptions do.

How Does It Help?

This formula supports your cardiovascular system by restoring nitric oxide—the molecule your endothelium stopped producing after your cardiac event. Delivered in clinical-strength doses your body can actually use.

Opens microvessels your stent can't reach — Restores blood flow in vessels 60× smaller than a hair where oxygen is actually delivered

Breaks the inflammatory cycle — Reduces IL-6 by 23-40% and interrupts the hs-CRP cascade driving your palpitations and chest pain

Calms autonomic overdrive — Provides sympathoinhibition at brainstem centers, reducing the 4am cortisol-triggered panic and constant fight-or-flight activation

Restores cellular energy — Promotes mitochondrial biogenesis (30-40% more mitochondria), helping compensate for statin-induced CoQ10 depletion

Works WITH your medications — Compatible with statins, beta-blockers, ACE inhibitors, aspirin. Addresses mechanisms your medications miss—not redundant, complementary.

Whether you're trying to avoid adding more medications or already on optimal medical therapy with persistent symptoms, this addresses the microvascular and inflammatory mechanisms driving the damage—not just numbing the pain.

When will I see results?

WEEK 1-2

Biochemical foundation phase. Plasma arginine increases, nitric oxide production rises. Blood pressure may begin trending down 2-4 mmHg. Most don't feel dramatic changes yet—this is normal. Loading depleted nutrients.

WEEK 4-8 (CRITICAL PERIOD)

This is when real improvements emerge. Endothelial function improves 1-2% (FMD). Blood pressure reduces 4-7/2-5 mmHg sustained. Exercise tolerance begins improving—walk farther without stopping. Breathlessness reduces during daily activities. Chest tightness decreases. Many report: "Week 5 I went to the hair salon without panic attacks." "Week 7 my PVCs dropped from 800/day to under 100." "Week 8 I walked to the mailbox without chest pain—first time in 14 months."

WEEKS 9-12

System consolidation. Less damage + ongoing repair + better function = calmer baseline. First "easy" nights in years. This is when people call it "worth it." Many report: "Week 10 I slept through the night without waking at 4am terrified." "Week 12 my blood flow improved 43% on stress echo."

MONTH 3-6 (MAXIMAL BENEFIT)

Dramatic cardiovascular improvements. Coronary blood flow reserve improved up to 149% in clinical studies. Cardiac function improves (LVEF increased 20% in heart failure patients). Sustained symptom reduction—fewer angina episodes, better exercise capacity. Quality of life significantly enhanced. Effects may persist weeks after stopping (durability demonstrated).

Verified by Cardiologists & Clinical Research

This formula uses well-researched amino acids with published studies showing their role in microvascular function, endothelial repair, and cardiovascular symptom reduction.

The Science:

149% improvement in coronary blood flow reserve with L-Arginine 9g/day for 6 months (Circulation, American Heart Association)

20% increase in left ventricular ejection fraction with L-Citrulline 3g/day for 4 months in heart failure patients (European Journal Preventive Cardiology)

12% improvement in exercise tolerance (6-minute walk test: 450m → 505m) with L-Arginine 3.32g/day in post-MI cardiac rehab patients (P<0.0001)

23-40% reduction in IL-6 inflammation with L-Arginine supplementation in CABG patients (Meta-analysis, cardiac surgery populations)

50% of post-cardiac patients have microvascular dysfunction despite patent stents—vessels too small to see on angiography (American Heart Association)

All ingredients are third-party tested for purity, potency, and safety.

Made in USA in FDA-registered, GMP-certified facility.

No pharmaceutical nitrates. No proprietary blends. No underdosing. Just clinical-strength support for what your stent can't reach.

Your Heart Is Starving

Four AM. Heart pounding. Is this it again?

You've been to the ER six times since your stent. Tests say nothing's wrong. Your cardiologist says your stent is "perfect."

But you're not fine.

Here's what they're not checking:

Your stent opened the highway. But inflammation is squeezing shut side streets 60× smaller than a hair—the microvessels that actually deliver oxygen to your heart.

These vessels are invisible on standard angiography. 50% of post-cardiac patients have closed microvessels despite "perfect" stents.

Your body stopped making nitric oxide—the molecule that keeps these tiny vessels open, calms inflammation, and stops your sympathetic nervous system from screaming.

This isn't your fault.

Two Molecules. One System. Clinical Doses That Actually Work.

Your body needs:

L-CITRULLINE (bypasses gut, 105% absorption, sustained elevation)

L-ARGININE (direct substrate, immediate availability)

SYNERGISTIC COMBINATION (together they exceed either alone)

CLINICAL-STRENGTH DOSING (3,000mg + 2,000mg = 7,000mg arginine equivalent)

TARGETS MICROVESSELS (opens vessels stents can't reach)

This formula delivers all of the above. In the right forms. At the right doses. Backed by cardiovascular research showing 149% coronary flow improvement.

Two servings daily with meals. That's it.

Competitors Use 1,000mg. Clinical Trials Used 9,000mg.

Most "NO boosters" use 1,000-1,500mg L-Arginine to save costs.

Clinical trials showing cardiovascular benefits used 6,000-9,000mg daily.

Let me be specific:

What DOESN'T work:

  • 1g/day L-Arginine: No blood pressure change, no symptom improvement
  • 2g/day L-Arginine: NO BP effects or exercise tolerance changes
  • Most "NO boosters": 1,500mg arginine + 750mg citrulline = 83% below therapeutic threshold

What DOES work:

  • 9g/day L-Arginine: 149% improvement in coronary blood flow reserve (Circulation, AHA)
  • 3g twice daily L-Citrulline: Significant FMD improvement, sustained arginine elevation
  • 6-9g daily range: Proven effective in clinical trials

This formula: 3,000mg L-Arginine + 2,000mg L-Citrulline per serving
