Melonex Capsules: What Is in the Shell, the Count and How to Store Them
Melonex comes as capsules, 60 to a bottle. The label names a hydroxypropyl methylcellulose shell, two other ingredients (microcrystalline cellulose and magnesium stearate) and one 500 mg blend of three amino acid forms. It does not print the capsule size, color or the amount of each amino acid.

What is inside one Melonex capsule?
One capsule holds a 500 mg proprietary blend of three amino acid forms, plus the shell and two helper ingredients. The label prints no more than that.
| Part | What the label says | Amount |
|---|---|---|
| Active blend | L-Citrulline dl-Malate, L-Arginine (Alpha-Ketoglutarate dihydrate), L-Arginine HCL | 500 mg total |
| Shell | Hydroxypropyl methylcellulose | Not published |
| Filler | Microcrystalline cellulose | Not published |
| Flow aid | Magnesium stearate | Not published |
The Supplement Facts panel must list each dietary ingredient, but names inside a blend may skip their own amounts 1. That is why the three amino acid forms share a single 500 mg line.
What is the capsule shell made of?
The shell is hydroxypropyl methylcellulose, a cellulose material that comes from plant fiber.
What the label gives
The material name, in the other ingredients line. Nothing about size, color or how fast it opens.
What it does not give
No allergen statement is printed. We cannot call Melonex allergen-free or vegan from the label alone.
What to do with that
If you react to certain additives or follow a strict diet, ask the order desk (the number on the sales site checkout) for a written answer before you buy.
You swallow the capsule whole with the glass of water the label asks for. Opening it to mix the contents into food is not a use the label describes.
How many capsules come in a bottle?
A bottle holds 60 capsules, which is 60 servings of one capsule each.

See packsWhy does a capsule need fillers?
Fillers and flow aids help a powder fill the shell evenly. They are common in capsules and are not the active part.
- Microcrystalline cellulose adds bulk so the powder fills the shell the same way each time.
- Magnesium stearate helps the powder flow through the filling machine.
- Neither is listed with an amount, so we cannot say how much of each sits in a capsule.
Because the blend is only 500 mg, part of the capsule weight is not amino acid at all. We cannot tell how much, since the full fill weight is not printed. The Supplement Facts page shows the panel line by line.
How should you store the capsules?
Keep the bottle cool and dry, away from children, and do not use it if the seal is damaged or missing.
Those are the label's own storage lines. Put the bottle away from a hot window, a stove or a bathroom shelf where steam builds up. Check the seal when you open a new bottle. If it is broken, contact the seller and do not take a capsule. Supplements are not approved by FDA before sale, so the buyer does the checking 2.

FAQ01
Melonex questions people ask
What size are Melonex capsules?
The label does not print a capsule size or color. Ask the order desk if you have trouble swallowing capsules.
Are Melonex capsules vegetarian?
The shell is hydroxypropyl methylcellulose, a plant-fiber material, but no vegetarian or vegan statement is printed, so we do not make one.

The label says to take it with 8 oz of water and does not describe opening it. Ask a pharmacist before changing how you take it.
How long do 60 capsules last?
Sixty days at one capsule a day, or 30 days at the label's limit of two.
