Melonex FAQ: Clear Answers to the Questions People Search Most

Melonex is a capsule dietary supplement sold as "Melonex Advanced Support" for heart and circulation support. Each capsule contains a 500 mg blend of L-citrulline DL-malate, L-arginine alpha-ketoglutarate and L-arginine HCl; each bottle holds 60 capsules.

The label names Instituto Experience of Lakeland, Florida, as distributor and says it is made in the USA in an FDA-registered facility. The sales page footer credits Eagle Labs, the checkout says Melonex Research and the terms name GEX Corporation LLP. The actual manufacturer is not named.

No. It is a dietary supplement. It is not approved to diagnose, treat, cure or prevent any disease, including high blood pressure.

Yes, in category terms. Its ingredients are the amino acids the body uses to make nitric oxide.

That is the product line name printed on the label. It is a marketing name; there is no standard or basic version listed by the maker, and "advanced" does not refer to a higher dose.

No. Citrulline was first found in watermelon and is named after it, which may explain the brand name, but the label lists purified amino acids, not watermelon extract.

The label does not say. Citrulline malate is part of a 500 mg blend with two arginine forms. Even if the whole blend were citrulline malate, one capsule would hold roughly 250 to 330 mg of citrulline.

Also not stated. The two arginine forms share the 500 mg blend with citrulline malate, which is listed first and is probably the largest part.

It is far below the doses used in trials: 4 to 24 grams a day for arginine and about 3 to 6 grams for citrulline. One capsule contains half a gram of all three ingredients combined.

No caffeine, yohimbe or other stimulant is listed.

The maker does not say. Blends are legal and protect a recipe from competitors, but they stop buyers from comparing doses with research. You can ask the maker for the per-ingredient amounts.

For raising blood arginine, yes. Citrulline avoids breakdown by arginase enzymes in the gut and liver, so oral citrulline raises plasma arginine more efficiently than oral arginine in human studies.

A hydroxypropyl methylcellulose (plant cellulose) capsule, microcrystalline cellulose and magnesium stearate.

One capsule daily with an 8 oz glass of water. The label allows up to two a day. Do not exceed two.

The maker suggests the morning. Any consistent time works; consistency matters more than the hour.

The label does not require food. If it bothers your stomach, take it with breakfast.

The label does not address it. The powder is sour if citrulline malate is the main ingredient; swallowing the capsule whole is the intended use.

The label allows up to two a day and does not say whether to split them. Taking both in the morning is simplest; if you notice light-headedness, split them morning and afternoon or go back to one.

Take the next one at the usual time. Do not double up to make up for it.

There is no study of Melonex. Trials of its ingredients measured changes over several weeks. Plan a six-to-eight-week trial with home readings and decide before day 60.

Only by measuring. Take a week of home readings before you start, then compare weekly averages. How you feel is not a reliable guide to blood pressure.

Gram-dose arginine trials averaged about 5 mmHg systolic. At Melonex's dose, any effect is likely to be smaller and may be indistinguishable from normal variation.

Yes. Citrulline and arginine have no known withdrawal effect. Stopping a prescribed blood pressure medicine suddenly is a different matter and should only be done with your prescriber.

Possibly a little, through nitric oxide, but cold extremities have many causes, including thyroid problems and artery disease, that need a proper check.

For most healthy adults, citrulline and arginine at half a gram to a gram a day are well tolerated. The main risks are interactions with blood pressure drugs, nitrates and ED drugs, and use after a heart attack.

Only with your prescriber's agreement. Effects can add up, and your medication dose may need watching.

Ask your doctor first. PDE5 inhibitors act on the same pathway, and combining vasodilators can lower blood pressure too far.

Not without a cardiologist's approval. In the VINTAGE MI trial, arginine after a heart attack showed no benefit and more deaths, and the trial was stopped.

Yes, adults of either sex, but the label excludes pregnancy and breastfeeding without a physician's advice.

Ask your nephrologist first. The kidneys convert citrulline to arginine and handle amino-acid nitrogen, and the label advises anyone with a known medical condition to consult a physician.

It is possible in theory, mainly when combined with other medicines that lower pressure. Dizziness when standing up, fainting or unusual tiredness are reasons to stop and check your readings.

Few at this dose. Large doses of arginine cause stomach upset and diarrhea. Dizziness on standing can occur if blood pressure drops, especially with other medicines.
