Melonex Official Website: Capsules for Heart and Circulation Support with L-Arginine and L-Citrulline

Quick answer

Melonex is a capsule dietary supplement that pairs L-citrulline DL-malate with two forms of L-arginine in one 500 mg blend. The label says one capsule a day with 8 oz of water, up to two. These amino acids feed nitric oxide, which relaxes blood vessels. Trials used grams a day, and no study has tested Melonex itself.

What it is01

What is Melonex?

Melonex is a dietary supplement sold as capsules, 60 to a bottle. Each capsule holds one 500 mg proprietary blend of three amino acid forms: L-citrulline DL-malate, L-arginine alpha-ketoglutarate and L-arginine HCl.

The front of the bottle reads "Heart Support*", "Circulation Support*" and "Natural Formula*". The asterisk points to the standard FDA statement: these claims have not been evaluated, and the product is not meant to diagnose, treat, cure or prevent any disease (FDA, structure/function claims).

Melonex is not a blood pressure medicine. It also has nothing to do with the meloxicam painkiller sold under the same name in parts of South Asia, a point we explain further down.

The short version

  • Three amino acid forms that the body uses to make nitric oxide
  • One capsule a day with water, two at most
  • A bottle lasts 60 days at one a day, 30 days at two
  • No trial of the product; the doses sit far below the studied amounts

Claims vs evidence02

Can Melonex lower blood pressure?

Not in any study of Melonex, because none exists. Its ingredients have lowered readings a little, at doses many times higher.

No, there is no evidence that Melonex lowers blood pressure. Nobody has run a trial on the capsules. What exists are trials of the single ingredients.

Eleven trials of oral L-arginine at 4 to 24 g a day lowered systolic pressure by about 5.4 mm Hg and diastolic by about 2.7 (Dong 2011, arginine meta-analysis). L-citrulline at 3 to 9 g a day lowered systolic pressure by about 4.1 mm Hg (Barkhidarian 2019, citrulline meta-analysis). One Melonex capsule holds 0.5 g of the whole blend.

  1. Sales page“targeted nutritional support for heart health, healthy blood pressure, and overall cardiovascular wellness”No trial has tested Melonex. Arginine and citrulline trials found small blood pressure drops at grams a day; one capsule holds 0.5 g of blend. (Dong 2011, arginine meta-analysis) (Barkhidarian 2019, citrulline meta-analysis) (NCCIH, hypertension digest)
  2. Label icon“Heart Support*” with the FDA asteriskStructure/function wording, allowed with the FDA statement. It is not a claim to treat heart disease. (FDA, structure/function claims)
  3. Label icon“Circulation Support*”The pathway is real: arginine feeds nitric oxide, which relaxes vessel walls. Whether 0.5-1 g a day moves it is not shown. (Cziraki 2020, arginine-NO pathway) (Schwedhelm 2008, citrulline kinetics)
  4. Label icon“Natural Formula*”The label does not say how the amino acids were made or what 'natural' covers. The capsule adds cellulose and magnesium stearate. (21 CFR 184.1440, magnesium stearate)
  5. Supply count2 bottles as a “60-day supply”That math uses 2 capsules a day. At the label's base dose of 1 a day, 2 bottles last 120 days. (Melonex sales page)
  6. Guarantee“60-Day Guarantee”, claims “after at least 30 days of continuous use”In practice the window to ask is day 30 to day 60. Mark both dates when you order. (Melonex sales page)
  7. Page footer“©Melonex Research 2026”The sales page names no study, no researcher and no lab result. A company name is not research. (Melonex sales page) (FTC, health products guidance)

Claims as printed on the sales page (Melonex sales page) and the label. Health claims need competent and reliable scientific evidence, generally human trials of the same product (FTC, health products guidance).

Keep taking prescribed medicine

Do not stop, skip or cut a blood pressure or heart medicine because you started a supplement. Arginine can add to those drugs and push pressure too low, so tell your doctor or pharmacist before you begin (Mayo Clinic, L-arginine).

How you take it03

How do you take Melonex capsules?

One capsule with a full glass of water. The label allows a second one a day and stops there.

Take one capsule a day with an 8 oz glass of water. The label says you may take up to two capsules daily. It names no time of day and no link to meals, so pick a time you will remember.

A bottle holds 60 capsules. That is 60 days at one a day or 30 days at two. The sales page counts its supply the second way, two bottles for 60 days (Melonex sales page).

  1. 01

    Check the seal

    The label says not to use the bottle if the safety seal is damaged or missing. Look before you open a new one.

  2. 02

    One capsule, 8 oz of water

    Swallow one capsule with a full glass of water. That is the label's base dose, and a bottle lasts 60 days at it.

  3. 03

    Up to two a day, never more

    The label allows a second capsule a day. Two a day is how the sales page counts its supply: 30 days a bottle.

  4. 04

    Log your readings, review at day 30

    Guarantee claims open after 30 days of use and close at 60 days. Share a home blood pressure log with your doctor.

Directions as printed: "As a dietary supplement, take one (1) capsule daily with an 8 oz. glass of water. May take up to two (2) capsules daily." More detail is on the how to take it page.

Ingredients04

What is inside a Melonex capsule?

Six label lines: a three-part 500 mg blend, then the capsule shell and two processing aids.

A Melonex capsule holds a 500 mg proprietary blend of L-citrulline DL-malate, L-arginine alpha-ketoglutarate dihydrate and L-arginine HCl, listed in that order. The other ingredients are a hydroxypropyl methylcellulose capsule, microcrystalline cellulose and magnesium stearate.

A proprietary blend only has to show its total weight and the order of its parts, from most to least (21 CFR 101.36, blends). So citrulline is the biggest share, and arginine HCl the smallest.

  1. 1L-Citrulline DL-MalateBlend line 1 · about 167-500 mg per capsule
  2. 2L-Arginine (Alpha-Ketoglutarate dihydrate)Blend line 2 · at most 250 mg per capsule
  3. 3L-Arginine HCLBlend line 3 · at most 167 mg per capsule
  4. 4Hydroxypropyl methylcelluloseThe capsule shell: a plant-cellulose (HPMC) capsule, not gelatin
  5. 5Microcrystalline celluloseA filler made from purified plant cellulose that helps the powder flow and fill evenly
  6. 6Magnesium stearateA flow agent used in tiny amounts so powder does not stick to machines

From the Supplement Facts panel and the other-ingredients line on the label. Lines 1-3 are the blend, listed from most to least by weight (21 CFR 101.36, blends). Lines 4-6 are the capsule shell and two processing aids.

Ingredient profiles

The plates are illustrations made for this site. The full panel is on the supplement facts page.

The label05

What does the Melonex label actually say?

Fifteen numbered spots on the flat label. Tap one to read that part in plain words; on a phone, the label scrolls sideways.

The label says Melonex is a dietary supplement of 60 capsules, one capsule per serving, with a 500 mg blend and no single amounts. It also carries the caution, the storage line, the made-in-USA line and the distributor: Instituto Experience of Lakeland, Florida.

The maker is not named. "Manufactured in an FDA registered facility" means the plant is registered with FDA, which is not the same as FDA approval (FDA, supplement Q&A).

Tap a number to read that part of the label.

  1. Suggested use

    One capsule a day with an 8 oz glass of water. Up to two a day. No time of day is printed.

  2. Storage

    Keep away from heat, light and humidity to preserve freshness.

  3. Caution

    Do not exceed the dose. Pregnant or nursing, under 18, or a known medical condition: ask a physician first.

  4. Keep out of reach

    Also: do not use if the safety seal is damaged or missing; store in a cool, dry place.

  5. Made in the USA

    'Made in the USA with globally sourced ingredients.' The countries are not named.

  6. Distributor

    Distributed for INSTITUTO EXPERIENCE, Lakeland FL 33804, +1 (507) 448-8190. The maker is not named.

  7. Emblem

    A framed red dot between gold rules: brand art, not a seal or a certification.

  8. Name and line

    Melonex, ADVANCED SUPPORT. 'Advanced' is brand wording; nothing on the label defines it.

  9. Three icons

    'Heart Support*', 'Circulation Support*' and 'Natural Formula*', each with the FDA asterisk.

  10. Count

    '60 CAPSULES', 'DIETARY SUPPLEMENT'. Sixty days at one a day, thirty at two.

  11. Serving size

    1 capsule per serving, 60 servings per container.

  12. Proprietary blend

    500 mg for three ingredients together: L-citrulline DL-malate, L-arginine AKG, L-arginine HCl. Single amounts are not shown.

  13. Other ingredients

    Hydroxypropyl methylcellulose (the capsule), microcrystalline cellulose, magnesium stearate.

  14. FDA statement

    The standard asterisk statement: not evaluated by the FDA, not intended to diagnose, treat, cure or prevent any disease.

  15. Facility line

    'Manufactured in an FDA registered facility.' Registration is not FDA approval.

Dose vs research06

Is 500 mg of arginine and citrulline enough to matter?

It is well below what blood pressure trials used. Even the most generous reading of the label falls short.

Probably not, if the trials are the guide. Two capsules give 1 g of blend a day. Citrulline trials started at 3 g, and arginine trials at 4 g (Barkhidarian 2019, citrulline meta-analysis) (Dong 2011, arginine meta-analysis).

The label hides each line's amount. But in a 500 mg blend of three, listed by weight, citrulline holds 167 to 500 mg, and the two arginine forms share at most 333 mg. Part of each weight is the salt partner, too.

  • L-citrulline (line 1)

    At most 33% of the low end at 2 capsules
    1 capsule, even split0.17 g
    2 capsules, even split0.33 g
    2 capsules, most the label allows1 g
    About 3-9 g a day in blood pressure trials3-9 g

    Not printed: line 1 of a 500 mg blend of 3, so 167-500 mg a capsule. (Barkhidarian 2019, citrulline meta-analysis)

  • L-arginine, both forms (lines 2 + 3)

    At most 17% of the low end at 2 capsules
    1 capsule, even split0.33 g
    2 capsules, even split0.67 g
    About 4-24 g a day in blood pressure trials4-24 g

    Not printed: lines 2 and 3 share what line 1 leaves, at most 333 mg a capsule. (Dong 2011, arginine meta-analysis)

Red bars: what 1 or 2 capsules can hold, in grams. The label prints only the 500 mg blend total; we show an even split (about 167 mg a line) and the most the label order allows. Gold bars: daily amounts used in blood pressure trials; the light extension shows the range. The weights include the salt partners (malate, alpha-ketoglutarate, HCl), so the citrulline and arginine inside are lower still.

What the research says about the ingredients in Melonex. No trial of Melonex exists.
IngredientEvidenceWhat it found
L-arginine11 trials, 387 people (Dong 2011, arginine meta-analysis)About 5.4/2.7 mm Hg lower at 4-24 g a day
L-citrulline8 trials (Barkhidarian 2019, citrulline meta-analysis)About 4.1 mm Hg lower systolic at 3-9 g a day; diastolic change not significant
Citrulline vs arginineDosing study (Schwedhelm 2008, citrulline kinetics)Oral citrulline raised blood arginine more than oral arginine did
Arginine after a heart attackVINTAGE MI trial (VINTAGE MI trial, JAMA 2006)Stopped early: 6 deaths on arginine, none on placebo
Citrulline for exercise12 studies (Trexler 2019, citrulline exercise)A small strength and power benefit at 3 g or more

The step-by-step math is on the Melonex dose check page, and the two amino acids are compared in arginine vs citrulline.

Label claims07

What do the Melonex heart and circulation claims mean?

Three icons on the label and one line on the sales page, each next to what studies of the ingredients found.

They are structure/function claims, the kind a supplement may print with the FDA disclaimer. A seller must have support for them but does not need FDA approval first (FDA, structure/function claims).

They are not claims to treat high blood pressure or heart disease. Only a drug may make those (FDA, structure/function claims).

Icons cropped from the Melonex label; the fourth image is the label front. Claims as worded on the label and the sales page (Melonex sales page).

Safety08

Who should not take Melonex without a doctor?

Five questions. A yes means a talk with your doctor or pharmacist first, and two of them mean do not start.

Anyone who has had a heart attack should not start Melonex without their cardiologist. In the VINTAGE MI trial, arginine after a heart attack was stopped early when six patients on it died and none on placebo did (VINTAGE MI trial, JAMA 2006).

People on blood pressure medicine, nitrates or erectile-dysfunction drugs need a doctor's view first, because arginine may make pressure drop too low (Mayo Clinic, L-arginine). So do pregnant or nursing women and anyone under 18, as the label itself says.

1. Do you take blood pressure medicine, a nitrate (such as nitroglycerin) or an erectile-dysfunction drug (such as sildenafil or tadalafil)?
2. Have you ever had a heart attack?
3. Are you pregnant or nursing, or under 18?
4. Do you get dizzy when you stand up, or has a doctor said your blood pressure runs low?
5. Are you buying this for a dog, a cat or another animal?
Answer all fiveYour result shows here. It is a checklist, not medical advice.
Other cautions

Arginine may raise potassium and should not be combined with potassium-sparing diuretics; it may add to blood thinners and diabetes drugs (Mayo Clinic, L-arginine). Avoid it during an active herpes outbreak (Health Library, Arginine). More on side effects and interactions.

Know your numbers09

What do your blood pressure numbers mean?

The five categories the American Heart Association uses, a reading finder, and the signs that need 911.

A normal reading is under 120 systolic and under 80 diastolic. Stage 1 high blood pressure starts at 130 or 80, and stage 2 at 140 or 90 (AHA, blood pressure readings).

About 48% of U.S. adults have high blood pressure, and only about 1 in 4 of them has it under control (CDC, high blood pressure facts). Knowing your own numbers, measured at home the right way, is worth more than any capsule (AHA, home BP monitoring).

  1. NormalTop number Under 120Bottom number and under 80
  2. ElevatedTop number 120-129Bottom number and under 80
  3. Stage 1 highTop number 130-139Bottom number or 80-89
  4. Stage 2 highTop number 140 or higherBottom number or 90 or higher
  5. Severe: call your doctor nowTop number Over 180Bottom number and/or over 120

Type both numbers from one reading to see its category. One reading is not a diagnosis; a doctor uses repeat readings.

Categories from the American Heart Association (AHA, blood pressure readings). Nearly half of U.S. adults have high blood pressure (CDC, high blood pressure facts). A reading over 180/120 with chest pain, shortness of breath, back pain, weakness, vision change or trouble speaking needs 911.

When to call 911

  1. Chest discomfortPressure, squeezing or pain that lasts or comes back
  2. Pain that spreadsArm, back, neck, jaw or stomach
  3. Short of breathWith or without chest discomfort
  4. Face droopingOne side of the face droops or feels numb
  5. Arm weaknessOne arm drifts down when both are raised
  6. Speech troubleSlurred speech or hard to understand

Call 911Any of these signs, even if they go away. Note the time they started. Do not drive yourself to the hospital.

Low?Dizzy, light-headed, blurry vision or fainting, especially on standing, can mean blood pressure fell too low. Sit or lie down and call your doctor.

Warning signs from the American Heart Association (AHA, warning signs); low blood pressure signs from NHLBI (NHLBI, low blood pressure). Arginine and citrulline can lower blood pressure, more so with nitrates or erectile-dysfunction drugs (Mayo Clinic, L-arginine).

Name mix-up10

Is Melonex the same as meloxicam?

No. A meloxicam painkiller is sold as Melonex in some countries. These capsules contain no meloxicam.

No, Melonex capsules are not meloxicam. Meloxicam is a prescription NSAID painkiller with a boxed warning for heart attack, stroke and stomach bleeding (MedlinePlus, meloxicam). Melonex capsules are amino acids.

Searches for "Melonex injection", "Melonex oral suspension" or "Melonex for dogs" are almost always about that veterinary or prescription meloxicam. We give no doses for it. A vet sets an animal's dose, and repeated meloxicam can cause kidney failure in cats (FDA, pain relievers for pets).

Melonex capsules (this site)

Dietary supplement for adults. L-citrulline and L-arginine, 500 mg a capsule. Sold online in the US. Not for animals.

Melonex (meloxicam) elsewhere

A prescription NSAID sold as tablets, injections and suspensions, including for animals. Ask your doctor or vet about it, not a supplement seller.

The full comparison is on Melonex vs meloxicam, and pet questions are answered on Melonex and pets.

Verdict11

What are the pros and cons of Melonex?

The pros are a short, readable label, an easy routine and a 60-day guarantee. The cons are no product trial, small doses and a hidden split inside the blend.

Pros

  • Every ingredient named; no stimulants or herbs
  • One capsule a day with water
  • A bottle lasts 30 to 60 days
  • 60-day money-back guarantee; free US shipping on 3 or 6 bottles
  • From $49 a bottle on the 6-pack

Cons

  • No trial of the product itself
  • 0.5-1 g a day, against 3 g or more in trials
  • Single amounts hidden in a proprietary blend
  • Not for people after a heart attack or on nitrates
  • Same name as an unrelated painkiller, which confuses searches

Our view: a simple amino acid capsule with a modest dose and honest-looking packaging. Treat it as a supplement, never as blood pressure care.

Melonex questions, short answers

What is Melonex used for?

Melonex is sold as a heart and circulation support supplement. The label claims 'Heart Support*' and 'Circulation Support*', and the sales page adds blood pressure wellness. It is not a medicine for any disease, and it is not the meloxicam painkiller of the same name (FDA, structure/function claims) (MedlinePlus, meloxicam).

What are the ingredients in Melonex?

A 500 mg proprietary blend of L-citrulline DL-malate, L-arginine alpha-ketoglutarate dihydrate and L-arginine HCl, in a hydroxypropyl methylcellulose capsule with microcrystalline cellulose and magnesium stearate.

How many Melonex capsules a day?

One capsule a day with an 8 oz glass of water. The label says you may take up to two a day. Do not take more than two.

Does Melonex work?

No study has tested Melonex. Its ingredients lowered blood pressure slightly in trials at 3-24 g a day (Dong 2011, arginine meta-analysis) (Barkhidarian 2019, citrulline meta-analysis); one capsule holds 0.5 g of blend. Expect a small dose of well-known amino acids, not a treatment.

Is Melonex safe?

For most healthy adults, arginine and citrulline are usually well tolerated at modest doses, though stomach upset can happen (Mayo Clinic, L-arginine). Do not use it after a heart attack, and ask your doctor first if you take blood pressure drugs, nitrates or sildenafil.

Can I give Melonex to my dog or cat?

No. These capsules are for adults. The pet product sold as Melonex in some countries is meloxicam, a different drug that only a vet should dose; repeated meloxicam can cause kidney failure in cats (FDA, pain relievers for pets).

How much does Melonex cost?

Two bottles are $158 ($79 each) plus $9.99 shipping, three are $207 ($69 each) and six are $294 ($49 each), with free US shipping on 3 and 6. That is about $2.63, $2.30 or $1.63 a day at two capsules.
