Each Melonex capsule is a hydroxypropyl methylcellulose shell filled with 500 mg of the proprietary blend plus microcrystalline cellulose and magnesium stearate. A bottle holds 60 capsules. The label says to take one capsule daily with 8 oz of water and allows up to two a day. The label prints no capsule size or colour.
Written by the Melonex label deskUpdated
What are Melonex capsules made of?
The shell is hydroxypropyl methylcellulose, often shortened to HPMC. It is a plant-cellulose capsule, the kind sold as a vegetarian alternative to gelatin.
Inside is the 500 mg blend and two fillers, microcrystalline cellulose and magnesium stearate. The brand's plate for the capsule shows the same three and marks them "not in the blend". The label gives no capsule size, colour or weight, so we do not describe them.

How many capsules are in a bottle?
A bottle holds 60 capsules and 60 servings, because one serving is one capsule.
500 mgone Proprietary Blend per capsule, amounts of the three names not printed
Proprietary Blend 500 mg- L-Citrulline DL-Malate167 to 500 mg
- L-Arginine alpha-ketoglutarateup to 250 mg
- L-Arginine HClup to 167 mg
Bars show the widest range the label order allows for each name 1. The real split is not printed.
At the label's lowest dose of one capsule daily, a bottle lasts 60 days. At two a day it lasts 30. The sales site's packs of 2, 3 and 6 bottles therefore cover about 120, 180 or 360 days at one a day 2.

How should you swallow a capsule?
Sit or stand upright, take a mouthful of water first, place the capsule on your tongue, and swallow with the rest of the 8 oz.
The label says one capsule daily with 8 oz of water. Water helps the capsule travel down and helps it open in the stomach. Do not chew it or open it into a drink unless a pharmacist has told you it is fine; the label does not give that instruction. If swallowing pills is hard, ask a pharmacist for tips instead of changing the form yourself.

How do you store the bottle?
Keep it cool and dry, away from heat, light and humidity, with the safety seal intact until first use, and out of reach of children.
A bathroom shelf is a poor spot because of steam. A car glovebox is worse. Keep the lid shut tight after each use. If the seal is broken or missing when the parcel arrives, do not use the bottle and contact the order desk. See the shipping page for what to do on arrival.

See packsWhat does the made-in line mean?
The label says Made in the USA with globally sourced ingredients, in an FDA registered facility.
Registration means the facility told FDA it exists. It is not an inspection result or approval of the product 3. The label names the distributor, Instituto Experience of Lakeland, Florida, and no factory. The brand's seals on the site are shown on the testing and quality page.

What do the fillers do?
The two fillers are there for the factory, not for you. They help the powder fill the shell evenly and slide through the machine.
Microcrystalline cellulose is a fine powder made from plant fiber. It bulks out a capsule so the fill is steady. Magnesium stearate is a salt of the fatty acid stearic acid. It works as a flow aid, stopping powder from sticking to metal. Both are common in capsules and tablets and are on the label under other ingredients, not in the blend.
The reason this matters is simple. The 500 mg blend weight is the active part. The capsule contains more material than that, and the label does not print the total fill weight. So a "500 mg capsule" is a 500 mg blend inside a larger capsule. Do not read the 500 mg as the total weight of what you swallow.
If you have a known reaction to any cellulose or stearate, say so to a pharmacist. Reactions are rare, but they are the sort of thing a pharmacist can check against your other medicines.
How do capsules fit into a day?
Pick one time, pair it with something you already do, and keep the 8 oz of water next to the bottle.
Most people find a steady spot works best: next to the kettle, the toothbrush or the pill box that already holds a prescribed medicine. If you take prescribed blood-pressure medicine, do not mix the two in one pill organiser without asking your pharmacist, since the pharmacist can flag timing issues 4. Keep the Melonex bottle in its original container so the lot number and directions stay with it.
If you miss a day, do not double up to catch up. The label allows up to two capsules a day, but it does not say the second one is better. Write the start date on the bottle. It matters if you later use the guarantee, which asks for at least 30 days of continuous use 2. See the guarantee page.
For travel, keep capsules in the original bottle in your carry-on bag, not in a checked bag, and not in a hot car. A small daily pill case is fine for a week away; write the lot number on a note so you can find it later.
Who should check before taking capsules?
Anyone on a prescribed medicine for blood pressure, heart rhythm, diabetes or blood clots should ask a pharmacist first. The capsule form does not change that.
The label itself asks pregnant or nursing mothers, anyone under 18, and anyone with a known medical condition to ask a physician before use. Arginine can add to the effect of blood-pressure medicines, and that is why NCCIH and other sources advise a check first 5. Read the medicines page and the side effects page before you order.
FAQ01
Melonex questions people ask
What size is a Melonex capsule?
The label does not print a size. The bottle holds 60 capsules of a plant-cellulose shell. Ask the order desk if size matters to you.
Are Melonex capsules vegetarian?
The shell is hydroxypropyl methylcellulose, a plant material. The label does not make a vegetarian or vegan statement, so ask in writing if it matters.
Can you open a Melonex capsule?
The label does not say to, and it does not forbid it either. Ask a pharmacist before opening any capsule, since contents can taste bitter or act differently.
How long does a bottle last?
At one capsule daily, 60 days. At the label's maximum of two capsules a day, 30 days.
Do you need food with the capsule?
The label says take with 8 oz of water and does not mention food. If your stomach feels upset, ask a pharmacist whether to take it with a meal.
Is Melonex a tablet or a powder?
Neither. It is a capsule. The sales site shows the same capsule form.
