VigRX Nitric Oxide

Description of the article « VigRX Nitric Oxide »

Quick Answer

VigRX Nitric Oxide Support is Leading Edge Health's daily blood-flow booster, built on a single patented blend — Velox®, a combination of L-citrulline and L-arginine. The two amino acids are the right ones for nitric oxide. But the maker publishes no amount for the blend or for either ingredient, anywhere — no Supplement Facts panel exists on any of its pages — so whether a serving reaches the roughly 1.2 g + 1.2 g level the blend's own patent specification calls effective cannot be verified. And despite marketing the product partly on blood-pressure benefits, the maker publishes no blood-pressure, nitrate or PDE5-interaction warning at all. We score it 5.5/10.

Quick Reference

• Price: $59.00 for 1 month (MSRP $69.00); 3 months $159.00 ($53/bottle), 6 months $299.00 ($50/bottle), 12 months $549.00 ($46/bottle) — full ladder published on the maker's official storefront
• Guarantee: 67-day money-back guarantee — return the empty containers (detailed terms exclude shipping; returns must be received within 67 days of delivery)
• Format: Tablets — 3 each morning with water on an empty stomach (stated only on the maker's official storefront; the brand page publishes no dose)
• Maker: Leading Edge Health (VigRX brand)
• Best for: Men who want a simple two-ingredient nitric-oxide routine and are comfortable that the dose itself is unverifiable

Our Verdict

There is a defensible product buried in this listing. L-citrulline plus L-arginine is a rational pairing — citrulline converts to arginine, arginine to nitric oxide — and the maker uses a real patented blend rather than a anonymous mix, with one genuine double-blind ingredient study (41 participants) behind the citrulline side and an honest ladder of published prices on its storefront.

What keeps the score mid-scale is that the product's central question cannot be answered from anything the maker publishes. Nitric oxide boosters live or die on dose, and this maker publishes none — not for the blend, not for either amino acid, and no Supplement Facts panel appears anywhere in its material. The blend's own supplier specification says the effective level requires about 1.2 g of each amino acid; whether three of these tablets deliver that, half of it, or a tenth of it is unknowable from the maker's pages. Layered on that is the batch's most serious safety gap: a vasodilator marketed partly on supporting healthy blood pressure, with no caution anywhere for the men most likely to buy it — those already on blood-pressure medication, nitrates or PDE5 inhibitors. The brand page's entire safety position is one sentence: "No side-effects have been reported."

Sub-scores

• Ingredients: 5.0/10 — Only two ingredients, both genuinely the right amino acids for nitric oxide, combined in a real patented blend (Velox®) — but the maker publishes no amount for the blend or either amino acid, so the dose question that decides an N.O. product cannot be answered from anything it publishes.
• Evidence: 5.0/10 — One ingredient-level human study cited with a sample size (double-blind, 41 participants, L-citrulline, exercise recovery) but no dose, authors or journal; the combination-superiority claim is asserted without a cited study; the Nobel / "Molecule of the Year" material is mechanism history, not product evidence; no finished-product trial is claimed.
• Maker credibility: 8.0/10 — An established Leading Edge Health / VigRX brand, a 67-day guarantee stated in writing with full terms published, and a GMP-certified facility claim on the storefront — marked down for the missing facts panel and the three different product names.
• Safety: 4.0/10 — No blood-pressure, heart-medication, nitrate or PDE5-interaction warning published anywhere, despite vasodilator positioning and blood-pressure benefit claims; the brand page's unqualified "No side-effects have been reported" is the only safety statement most buyers will see.
• Value: 5.0/10 — $59 for one month ($53/bottle on three, $50 on six, $46 on twelve) is mid-range for this brand, but the buyer cannot verify what quantity of L-arginine and L-citrulline that money buys — and generic versions of both amino acids with fully disclosed gram doses are widely available for less.

What Is VigRX Nitric Oxide?

VigRX Nitric Oxide Support is a daily tablet formula from Leading Edge Health, sold under the VigRX brand (it is also sold as "Nitric Oxide Support" on the maker's main store and "VigRX Nitric Oxide" on its retail store — three names for the same product). The maker positions it as the "blood flow layer" of a VigRX sexual wellness routine, and its stated targets run wide: cardiovascular support, endothelial health, sex drive, erection quality and hardness, gym pumps, training stamina and recovery, midday energy — and, in the maker's wider benefit list, healthy blood pressure, cholesterol, blood sugar, immune function, stress and cognition. Those are the maker's claims, attributed as such.

The maker's mechanism framing: nitric oxide relaxes blood vessels and improves blood flow, and production falls with age — "some studies say" men in their 40s produce 50% less than as teenagers, a figure the maker attaches to no identified study. The directions exist on only one maker page: the official storefront states 3 tablets each morning with water on an empty stomach, taken daily at the same time. The brand page and the maker's retail store publish no dose, no format and no bottle contents at all. The storefront's timeline: early improvements in energy and workout performance within the first week or two, with sexual-performance benefits building over several weeks of consistent use.

Key Ingredients

One patented blend, two amino acids — and the defining fact of this formula: no amounts are published for anything. Not for the blend, not for either ingredient, and no Supplement Facts panel is reproduced on any of the maker's pages.

• Velox® — the product's only named ingredient: a patented blend of the two amino acids below, described by the maker as a "patented, pharmaceutical-grade extract." The maker says supplementing with both together produces "significantly more nitric oxide" than either alone — a claim it asserts without citing a study for it.
• L-Citrulline — converts in the body to L-arginine. The one ingredient here with a cited human study behind it (below). Amount in this product: not published.
• L-Arginine — converts to nitric oxide, the vessel-relaxing messenger molecule. Amount in this product: not published.

Why the missing numbers matter more here than usual: Velox® is Kyowa Hakko's patented blend, and the supplier's own published specification says the effective dose requires a minimum of about 1.2 g of its L-citrulline plus 1.2 g of its L-arginine. That figure is the blend supplier's, not a claim this maker makes for this product — and because the maker publishes no amount at all, whether a daily serving of this product reaches that level cannot be verified. Third-party sites variously claim 3,000 mg servings and extra ingredients like beetroot or horny goat weed; none of that appears on the maker's pages, and we do not repeat it as fact.

What We Like

• The pairing is rational. Citrulline plus arginine is a legitimate nitric-oxide strategy, and the formula is nothing else — no filler botanicals riding along.
• A real patented blend, named. Velox® is an identifiable, specification-backed ingredient rather than a proprietary mystery mix — which makes the missing dose a paperwork failure, not a formula invention.
• One genuine ingredient study, with a sample size. The maker cites a double-blind study of 41 participants for L-citrulline — more methodological detail than most of this shelf provides, even if the dose, authors and journal go unpublished.
• Full price ladder published on the storefront — one, three, six and twelve months, with per-bottle prices. A buyer can price a full trial before checkout.
• The guarantee's full terms are published — including the limits (shipping excluded, returns received within 67 days, first two opened containers on multi-bottle orders), not just the headline.

Good to Know

• There is no dose to check — anywhere. No amount for the blend or either amino acid, no Supplement Facts panel, no tablet count per bottle on the maker's pages. The third-party figures in circulation (3,000 mg servings, beetroot, pomegranate) do not come from the maker and conflict with each other.
• The one cited study is about exercise, not erections. Forty-one participants, double-blind, L-citrulline, measuring recovery and muscle soreness after anaerobic exercise. It is ingredient-level evidence for a gym claim; it says nothing measured about sexual performance, and nothing about this product.
• The Nobel Prize is not evidence. The maker's pages lean on nitric oxide's 1992 "Molecule of the Year" honour and the 1998 Nobel Prize for its discovery. That is mechanism history — it establishes that nitric oxide matters, not that this product does anything. The brand page also muddles the two dates together in one section.
• Directions exist on only one of the maker's pages. The brand page and retail store — the pages a buyer reads for formula and evidence — publish no dose, format or bottle contents. Only the dedicated storefront states the 3-tablet morning dose.
• The safety wording differs by page. The storefront adds a generic "consult your healthcare provider" line; the brand page and retail store do not — a reader of the brand page alone gets the stronger, unqualified "no side-effects" claim.
• Free continental USA shipping is shown on the storefront packages, with interest-free instalment payments offered.

Who Should Not Use It

The maker publishes no product-specific safety section and no exclusion list for VigRX Nitric Oxide on any of its pages. Most importantly: nowhere — not on the brand page, not on the storefront, not on the maker's retail store — is there any warning about blood pressure, heart conditions, or interactions with nitrates, blood-pressure medication, heart medication or PDE5 inhibitors. Those are precisely the interactions that matter for a vasodilating nitric-oxide booster, and the maker simultaneously claims the product supports healthy blood pressure. The two positions sit side by side on its pages with nothing connecting them.

The maker's entire published safety position is this: the brand page's FAQ answers "Are there any side effects?" with "No side-effects have been reported," and the storefront adds a generic line advising readers with a health condition or medication to consult a healthcare provider. Our guidance, offered because the maker does not: if you take blood-pressure medication, nitrates, heart medication or a PDE5 inhibitor, do not start a nitric-oxide booster without asking your doctor first. That caution is standard for this ingredient class — and its absence from the maker's pages is a gap in the maker's paperwork, not evidence the conversation is unnecessary.

Where to Buy

Buy only from the official store so the guarantee applies: the official VigRX Nitric Oxide store. One month is $59.00 (MSRP $69.00); three months $159.00 ($53 per bottle), six months $299.00 ($50 per bottle) and twelve months $549.00 ($46 per bottle), with free continental USA shipping shown on the storefront.

FAQ

How much L-arginine and L-citrulline do I get per day?
Nobody can tell you from the maker's material: no amount is published for the Velox® blend or for either amino acid, and no Supplement Facts panel appears on any of the maker's pages. The blend supplier's own specification puts the effective level at about 1.2 g of each — whether this product reaches it is unverifiable.

How do I take it?
Per the maker's official storefront — the only maker page that states a dose — 3 tablets each morning with water on an empty stomach, daily, at the same time. The brand page and the maker's retail store publish no directions at all.

Has it been clinically tested?
No trial of the finished product is claimed. The maker cites one ingredient-level study (double-blind, 41 participants, L-citrulline, exercise recovery) without publishing its dose, authors or journal, and asserts — without a cited study — that combining the two amino acids produces superior nitric oxide levels.

Is it safe to take with blood pressure medication or Viagra-type drugs?
The maker publishes no warning about nitrates, blood-pressure or heart medication, or PDE5 inhibitors — anywhere. That silence is a gap, not an answer. Nitric-oxide boosters act on the same pathway those medications do; if you take any of them, ask your doctor before using this product.

How long before I notice anything?
The maker's storefront says many men notice early improvements in energy and workout performance within the first week or two, with sexual-performance benefits becoming more pronounced over several weeks of consistent daily use. Judge inside the 67-day guarantee.

What if it doesn't work for me?
The maker's 67-day money-back guarantee applies to empty-container returns, under the detailed terms above — returns received within 67 days of delivery, shipping excluded, one refund per customer.

Also Consider

• VigRX Plus — the same brand family's flagship daily formula, with a published placebo-controlled trial of the finished product; the documented erection-quality option in this range.
• VigRX Tongkat Ali — a single-herb formula whose LJ100 dose (200 mg) is published and matches its trials — the verifiable-dose alternative on the same shelf.
