About the product and the label
The label is the source for every answer in this group.
What is Melonex?
Melonex Advanced Support is a dietary supplement in capsules. The label says Heart Support*, Circulation Support* and Natural Formula*, with 60 capsules per bottle. It is not a medicine and not a treatment for any disease.
What is in Melonex?
One 500 mg Proprietary Blend of L-citrulline dl-malate, L-arginine alpha-ketoglutarate dihydrate and L-arginine HCL. Other ingredients are hydroxypropyl methylcellulose, microcrystalline cellulose and magnesium stearate. The amount of each of the three names is not printed.
How do you take Melonex?
Take one capsule daily with 8 oz of water, as the label says. The label allows up to two capsules a day. Do not exceed the recommended dose.
Does Melonex lower blood pressure?
This site makes no such claim, and the label does not. Studies of arginine and citrulline at gram doses show small, mixed changes, and none tested this product. Keep taking prescribed medicine.
Is Melonex a medicine?
No. It is sold as a dietary supplement. FDA does not approve supplements or their labeling before sale.
Who makes Melonex?
The label says it is distributed for Instituto Experience of Lakeland, Florida, and made in an FDA registered facility in the USA. The factory is not named.
Is Melonex FDA approved?
No supplement is. The label says made in an FDA registered facility, which means the facility is on a list, not that FDA passed the product.
Is Melonex the same as a medicine with a similar name?
No. The name matches other things in search. See the name check page, and read the label and the three ingredient names, not just the brand.
Is Melonex vegan?
The label makes no vegan statement. The shell is plant cellulose. Ask the order desk in writing if it matters to you.
How many capsules are in a bottle?
60 capsules, 60 servings. At one capsule a day a bottle lasts 60 days.
About safety and medicines
If you take a prescribed medicine, read this group before you order.
Who should ask a doctor first?
Anyone who takes blood-pressure medicine, a nitrate, a sildenafil-type medicine, a potassium-sparing diuretic, a blood thinner or diabetes medicine; anyone with kidney or liver disease or low blood pressure; and anyone pregnant, nursing or under 18.
Can I take Melonex with blood-pressure medicine?
Ask your doctor or pharmacist first. Arginine can add to the effect of blood-pressure medicines and lower pressure too far. Never cut back or stop a medicine on your own.
Can I take Melonex after a heart attack?
Do not start without your cardiologist's approval. Mayo Clinic, MSK and others advise against arginine after a recent heart attack.
What are the side effects?
The label lists none. Sources on arginine list stomach upset, bloating, diarrhoea and low blood pressure. Stop and call a clinician for dizziness or fainting.
When should I call 911?
For chest pain or pressure, trouble breathing, fainting, or face, arm or speech changes. Do not wait for a supplement to help.
Is Melonex safe for older adults?
The label has no age ceiling. Older adults often take several medicines, so a pharmacist check matters more.
Can I take Melonex while pregnant?
The label asks pregnant or nursing mothers to consult a physician first.
How do I report a bad reaction?
Stop the capsule, call your clinician, and report it to FDA MedWatch and to the order desk. Keep the bottle and the lot number.
Will Melonex show up on a drug test?
The label lists no drug or stimulant. If a test matters to your job, ask the order desk and your employer's medical officer.
Does Melonex contain caffeine?
No. The label lists no caffeine or herb.
