Melonex Capsules: Size, Shell, Count and Storage

Quick answer

Melonex capsules come 60 to a white bottle, in a hydroxypropyl methylcellulose (plant-cellulose) shell. Each holds a 500 mg proprietary blend of three amino acid forms. The label gives no capsule length or color, and asks you to keep the bottle away from heat, light and humidity.

How many Melonex capsules are in a bottle?

A Melonex bottle holds 60 capsules, and the label counts 60 servings of one capsule each. At the base dose of one a day, that is 60 days. At two a day, the most the label allows, it is 30 days.

The sales page sells two bottles as a 60-day supply, which only works at two capsules a day (Melonex sales page).

What is the Melonex capsule shell made of?

The Melonex capsule shell is hydroxypropyl methylcellulose, or HPMC, a plant-cellulose material. It is not gelatin. The label lists two more other ingredients: microcrystalline cellulose and magnesium stearate, which FDA affirms as generally recognized as safe (21 CFR 184.1440, magnesium stearate).

How big is a Melonex capsule?

The size of a Melonex capsule is not printed anywhere we can read. The blend weighs 500 mg per capsule, and the label does not say how much the other ingredients add. Judge the swallow with the bottle in hand, and take it with the 8 oz of water the label asks for.

The capsule and other ingredients page covers each non-blend line.
