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

The Microvascular Repair Timeline With Bioxtra
📅 Week 1-2
Biochemical changes (plasma arginine increases, NO production rises). Minimal symptomatic changes—this is the foundation phase.
📅 Week 4-8
First real improvements. Endothelial function improves 1-2%. Blood pressure reduces 4-7/2-5 mmHg. Exercise tolerance begins improving. Breathlessness reduces. Chest tightness decreases.
📅 Week 9-12
System consolidation. Less damage + ongoing repair = calmer baseline. First "easy" nights in years. Many report sleeping through the night without 4am panic.
📅 Month 3-6
Maximal benefit. Coronary blood flow reserve dramatically improved (up to 149% in studies). Sustained symptom reduction. Quality of life significantly enhanced.
The Studies That Back This Up
149% improvement in coronary blood flow reserve — L-Arginine 9g/day, 6 months (Circulation, AHA 1998)
23-40% reduction in IL-6 inflammation — L-Arginine in cardiac surgery patients (Meta-analysis)
12% improvement in exercise tolerance — 6-minute walk test: 450m → 505m (Post-MI cardiac rehab study)
20% increase in ejection fraction — L-Citrulline 3g/day, 4 months in heart failure (European Journal Preventive Cardiology)
Synergistic combination proven — 1g citrulline + 1g arginine > 2g of either alone (Journal of Nutritional Science, 2017)
50% of post-cardiac patients have microvascular dysfunction despite patent stents (American Heart Association)
Frequently Asked Questions
How do I take it?
How do I take it?
Mix 1 scoop with 6-8 oz of water, twice daily with meals. Stir or shake until fully dissolved. Can be taken with your other morning/evening medications.
When will I start to feel results?
When will I start to feel results?
WEEK 1-2: Biochemical foundation phase
WEEK 4-8: First real improvements—less breathlessness, better exercise tolerance
WEEK 9-12: System consolidation—sustained symptom reduction
MONTH 3-6: Maximal benefits—dramatic improvements in blood flow, cardiac function
Is it safe to take daily?
Is it safe to take daily?
Yes for stable patients >6 months post-event under medical supervision. Formula is non-GMO, third-party tested, and safe for long-term daily use when used appropriately.
How should I store it?
How should I store it?
Store in a cool, dry place away from sunlight. Keep container tightly sealed. No refrigeration needed.
How long does one bottle last?
How long does one bottle last?
Each bottle contains 30 servings (30 scoops). At standard dosing (1 scoop twice daily), one bottle lasts 15 days. Most customers order 2 bottles for a full month supply.
Is this backed by research?
Is this backed by research?
Yes. Every key ingredient is supported by peer-reviewed cardiovascular studies published in Circulation (AHA), JACC, NEJM, European Journal of Preventive Cardiology.
Is it third-party lab tested?
Is it third-party lab tested?
Yes, every batch is tested for quality, purity, and potency in GMP-certified facilities.
I'm already on statins/beta-blockers/ACE inhibitors. Can I take this too?
I'm already on statins/beta-blockers/ACE inhibitors. Can I take this too?
Yes—compatible with most cardiac medications. NOT compatible with nitrates (nitroglycerin, isosorbide) or potassium-sparing diuretics. Show your cardiologist the label. Monitor blood pressure as you may need medication dose reductions (good news).
What does it taste like?
What does it taste like?
Natural berry flavor. Mixes easily with water. Most customers find it pleasant-tasting and easy to drink.
