About Melonex02
What is Melonex, and who sells it?
Melonex is a capsule dietary supplement distributed for Instituto Experience of Lakeland, Florida. The label does not name the factory.
This website is run by Gomelonex, a USA authorized Melonex retailer. We are not the maker or the distributor, and we earn money when you order through our links.
What is Melonex?
Melonex is a dietary supplement in capsule form, sold 60 capsules to a bottle. Each capsule holds a 500 mg proprietary blend of L-citrulline DL-malate, L-arginine alpha-ketoglutarate and L-arginine HCl. The label claims heart and circulation support, with the FDA disclaimer (FDA, structure/function claims).
Is Melonex a real product?
Yes. Melonex is a real, labeled product distributed for Instituto Experience of Lakeland, Florida, and sold through a BuyGoods checkout. Being real is not the same as being proven: no trial has tested the capsules, and no customer review on this site is verified yet.
What is the Melonex website?
Gomelonex.com is run by Gomelonex, a USA authorized Melonex retailer that earns money from its order links. The brand's offer page is mymelonex.com/mlx-aff-buy-dtc/, while the mymelonex.com home page is a blank template. Our order buttons lead to the checkout for each pack.
Who makes Melonex?
The label does not name the manufacturer. It says Melonex is distributed for Instituto Experience, Lakeland FL 33804, and made in the USA with globally sourced ingredients in an FDA registered facility. Gomelonex is a retailer, not the maker or the distributor.
Does Melonex have FDA approval?
No. The FDA does not approve dietary supplements before they are sold (FDA, supplement Q&A). The label line about an FDA registered facility means the plant is registered with the agency, which is a different thing from approval of the product.
Is there melon extract in Melonex?
No melon or watermelon extract is listed on the label. The likely link is the name of L-citrulline, which comes from Citrullus lanatus, the scientific name of watermelon (Aguayo 2021, L-citrulline review). Watermelon holds about 0.7 to 3.6 g of citrulline per kg; the label does not say where its citrulline comes from.
Ingredients and label03
What is in the capsules, and what does the label say?
Each Melonex capsule holds a 500 mg proprietary blend of three amino acid forms, plus a plant-cellulose shell and two processing aids. The blend lists its parts from most to least by weight but gives no single amounts (21 CFR 101.36, blends).
That hidden split is the main gap on the label. The answers below show what the order of the lines does and does not tell you.
Why does the Melonex label hide each ingredient's amount?
Because the three amino acids sit in a proprietary blend. Federal rules let a blend show only its total weight, with the parts listed from most to least by weight (21 CFR 101.36, blends). So the label prints 500 mg for the blend and no single amounts.
How much L-citrulline is in one Melonex capsule?
The exact amount is not printed. As the first of three lines in a 500 mg blend, citrulline malate holds between about 167 and 500 mg a capsule. That weight includes the malate partner, so the citrulline itself is lower. An even split would be about 167 mg.
How much L-arginine does a Melonex capsule hold?
The two arginine lines together hold at most about 333 mg a capsule: arginine AKG at most 250 mg and arginine HCl at most 167 mg, salt partners included. Even at two capsules a day that stays under 1 g, while arginine trials used 4 to 24 g a day (Dong 2011, arginine meta-analysis).
Is the Melonex capsule shell gelatin?
No. The shell is hydroxypropyl methylcellulose, a plant-cellulose capsule rather than gelatin. The fillers are microcrystalline cellulose and magnesium stearate, which FDA affirms as generally recognized as safe (21 CFR 184.1440, magnesium stearate). The label makes no vegan or allergen claim, so ask the order desk if that matters to you.
Does Melonex contain caffeine, herbs or stimulants?
None are listed. The label names three amino acid forms in the blend and three other ingredients for the capsule and processing. There is no caffeine, no herb and no stimulant anywhere on the Supplement Facts panel.
What does Natural Formula mean on the bottle?
The label does not define it. “Natural Formula*” is one of three front icons, and its asterisk points to the FDA statement that the claim has not been evaluated (FDA, structure/function claims). The contents are amino acid salts and cellulose-based capsule parts; no natural-origin standard is named.
Taking the capsules04
How and when should you take Melonex?
Take one Melonex capsule a day with an 8 oz glass of water, and never more than two in a day. That is the whole of the label's directions.
The label names no time of day and no food rule. The step-by-step routine is on how to take Melonex.
How do you use Melonex?
Swallow one capsule a day with an 8 oz glass of water. The label says you may take up to two capsules daily, and no more. Check that the safety seal is intact before opening a new bottle, and keep it cool and dry.
When is the best time to take Melonex?
The label names no time of day and no rule about food. Pick a time you will remember, such as with breakfast or before bed. If you take two a day, the label does not say whether to take them together or apart.
Can I take Melonex every day?
Yes, the label is written for daily use: one capsule a day, up to two. It sets no limit in weeks or months. Anyone with a medical condition, or who is pregnant, nursing or under 18, should ask a physician first, as the label says.
What if I forget a Melonex capsule?
The label gives no missed-dose rule. The simple approach is to take the next capsule at your usual time. Whatever happens, stay within the label's limit of two capsules in one day, and never take extra to catch up.
How long does one bottle of Melonex last?
One bottle of 60 capsules lasts 60 days at one capsule a day, or 30 days at two. The sales page counts supply the second way, which is why it calls two bottles a 60-day supply (Melonex sales page).
Results and evidence05
Does Melonex work, and how fast?
No one can say whether Melonex works, because no trial has tested the capsules. The evidence comes from studies of arginine and citrulline alone, at much higher doses.
Those studies found small drops in blood pressure: about 5.4/2.7 mm Hg for arginine at 4 to 24 g a day (Dong 2011, arginine meta-analysis), and about 4.1 mm Hg systolic for citrulline at 3 to 9 g (Barkhidarian 2019, citrulline meta-analysis). A daily dose of two capsules adds up to 1 g of the whole blend.
Does Melonex really work?
No one knows, because no trial has tested Melonex. Its ingredients lowered blood pressure slightly in trials at 3 to 24 g a day (Dong 2011, arginine meta-analysis) (Barkhidarian 2019, citrulline meta-analysis), while two capsules give 1 g of the whole blend. Judge it as a small amino acid dose, not a treatment.
How long does Melonex take to work?
There is no tested timeline for Melonex. In the pooled arginine trials, results held when the analysis kept only trials lasting 4 weeks or more (Dong 2011, arginine meta-analysis), at far higher doses. The guarantee gives you 60 days, with claims opening after 30 days of use.
Will Melonex bring my blood pressure readings down?
There is no evidence that it will. Arginine at 4 to 24 g a day lowered readings by about 5.4/2.7 mm Hg in pooled trials (Dong 2011, arginine meta-analysis), and citrulline at 3 to 9 g lowered systolic by about 4.1 (Barkhidarian 2019, citrulline meta-analysis). A capsule holds 0.5 g of blend, so track readings with your doctor.
Does Melonex reduce swelling?
No. The capsules make no claim about swelling or inflammation, and arginine and citrulline are not anti-inflammatory drugs. The swelling question usually comes from the meloxicam drug sold as Melonex, which doctors prescribe for arthritis pain, swelling and stiffness (MedlinePlus, meloxicam).
Can Melonex help with workouts?
Not at its dose, as far as the research goes. Citrulline gave a small strength and power benefit at 3 g or more, taken before exercise (Trexler 2019, citrulline exercise). A Melonex capsule holds at most 500 mg of citrulline malate, and the label makes no exercise claim.

Is Melonex safe for you?
Melonex has no safety study of its own, but some people must talk to a doctor before taking it. The biggest flags are a past heart attack and medicines that lower blood pressure (Mayo Clinic, L-arginine).
The label itself asks pregnant or nursing mothers, anyone under 18 and adults with a known medical condition to consult a physician before use.
Never stop, skip or change a prescription because you started a supplement. Melonex is not a substitute for any medicine. The full list is on Melonex side effects.
What side effects can Melonex cause?
No side effects have been studied for Melonex itself. For arginine, Mayo Clinic lists nausea, abdominal pain, diarrhea, bloating, gout, headache, allergic reactions and worse asthma (Mayo Clinic, L-arginine). Citrulline was well tolerated in short studies (Aguayo 2021, L-citrulline review). Stop and call your doctor if a reaction worries you.
Is Melonex safe in pregnancy?
Do not start it without your doctor. The label asks pregnant or nursing mothers to consult a physician first, and one hospital health library advises against arginine supplements during pregnancy and breastfeeding (Health Library, Arginine). The same source says children and teens should not use arginine.
Can I take Melonex with blood pressure medicine?
Ask your doctor or pharmacist first. Mayo Clinic says arginine with blood pressure drugs may make pressure drop too low (Mayo Clinic, L-arginine). A reading below 90/60, dizziness or fainting is a reason to stop the capsules and call your doctor (NHLBI, low blood pressure).
Can I take Melonex after a heart attack?
No, not without your cardiologist. In the VINTAGE MI trial, arginine after a heart attack was stopped early when 6 people on it died and none on placebo did (VINTAGE MI trial, JAMA 2006). Mayo Clinic does not recommend arginine after a recent heart attack (Mayo Clinic, L-arginine).
Is Melonex safe with sildenafil or nitrates?
Talk to your doctor before combining them. Arginine with nitrates or sildenafil may push blood pressure too low (Mayo Clinic, L-arginine), and sildenafil itself must never be taken with nitrate medicines (MedlinePlus, sildenafil). Bring every bottle you take to the appointment.
Who should not take Melonex?
People who have had a heart attack should not start it without their cardiologist (VINTAGE MI trial, JAMA 2006). Anyone on nitrates, blood pressure drugs, blood thinners, diabetes medicine or potassium-sparing diuretics needs a doctor's view first (Mayo Clinic, L-arginine). So do pregnant or nursing women and anyone under 18.
Name mix-up07
Is Melonex a painkiller, an NSAID or a pet medicine?
No, Melonex capsules are none of those. The confusion comes from meloxicam, a prescription NSAID painkiller that is sold under the Melonex name in parts of South Asia, for people and for animals.
Searches for injections, syrups, boluses, oral suspensions, "Plus" products and doses for dogs or cats are about that drug. The capsules contain no meloxicam.
We never publish a meloxicam dose, a per-kilogram amount or a how-to for any animal. Ask the doctor, pharmacist or vet who knows the patient. Pet questions are on Melonex and pets.
Are Melonex and meloxicam the same medicine?
No. Melonex capsules are an amino acid supplement with no meloxicam in them. Meloxicam is a prescription NSAID, and in parts of South Asia one of its brand names is Melonex. The two share a name and nothing else. See Melonex vs meloxicam.
Is Melonex a painkiller?
Melonex capsules are not a painkiller. They hold L-citrulline and L-arginine, and the label claims only heart and circulation support. The painkiller with that brand name is meloxicam, which doctors prescribe for arthritis pain, swelling and stiffness (MedlinePlus, meloxicam).
Is Melonex an NSAID or an anti-inflammatory?
The capsules are neither. They are a dietary supplement of amino acids. Meloxicam, the drug sold as Melonex abroad, is a nonsteroidal anti-inflammatory drug with a boxed warning for heart attack, stroke and stomach bleeding (MedlinePlus, meloxicam).
Is Melonex an antibiotic?
No. Neither product is an antibiotic. The capsules are amino acids, and meloxicam is an NSAID painkiller, not a drug that kills germs. For an infection in a person or an animal, see a doctor or a vet.
Is Melonex used for fever?
The capsules are not a fever reducer (an antipyretic) and make no fever claim. MedlinePlus lists arthritis pain, swelling and stiffness as the uses of meloxicam (MedlinePlus, meloxicam), not fever. Ask a doctor or pharmacist what to use for a fever.
How do you use Melonex injection, oral suspension or syrup?
Only as a doctor or vet directs. Those forms belong to the meloxicam drug, not to the capsules, and we publish no doses, schedules or how-to steps for them. A wrong amount can harm a person, and repeated meloxicam can kill a cat (FDA, pain relievers for pets).
What are Melonex Plus, Melonex tablets and Melonex injection used for?
They are drug-side products of the meloxicam brand, sold for people and animals in parts of South Asia. Meloxicam is prescribed for pain and swelling as an NSAID (MedlinePlus, meloxicam); we do not know the exact contents of the Plus versions. Ask the prescriber or a pharmacist.
Can Melonex be given to dogs, cats, birds or rabbits?
Not the capsules, to any animal. The vet drug sold as Melonex is meloxicam, approved in the US for dogs and, for cats, only as a one-time injection around surgery (FDA, pain relievers for pets). For any pet, ask your vet. If a pet swallows capsules, call your vet or 1-888-426-4435 (ASPCA, top pet poisons).
Is Melonex Plus safe in pregnancy, for people or cattle?
Ask the doctor or vet before any use in pregnancy. Melonex Plus is a drug-side product we cannot describe, and meloxicam carries real risks (MedlinePlus, meloxicam). For the capsules, the label asks pregnant or nursing mothers to consult a physician first. The capsules are never for animals.
