Maxentra Ingredients: Arginine, Citrulline and a 30 mg Blend

By the Maxentra Editorial Team · Updated October 22, 2026

Search for Maxentra ingredients and you will find confident claims on other sites. We use only what the source page lists, and we mark what is missing.

The three amino acid forms

• L-arginine HCL. A salt form of the amino acid arginine, used by the body to make proteins and the signalling molecule nitric oxide.
• L-arginine alpha-ketoglutarate dihydrate. Arginine paired with alpha-ketoglutarate, a compound in energy metabolism.
• L-citrulline malate. Citrulline combined with malic acid. The body can convert citrulline into arginine.

See Mayo Clinic: L-Arginine for a plain summary of L-arginine and its cautions.

The 30 mg problem

All three share a 30 mg blend per capsule. The source article notes that most citrulline studies used single doses of roughly 3,000 to 8,000 mg. A blend this small cannot contain those amounts, so studies at those doses do not describe Maxentra.

Other ingredients

Organic white rice flour, hydroxypropyl methylcellulose (the capsule) and magnesium stearate.

How to read a Supplement Facts panel

1. Serving size. The source says one capsule daily.
2. Proprietary blend. A single total with no breakdown means you cannot compare doses.
3. % Daily Value. An asterisk or “not established” means none is set.
4. Other ingredients. Capsule shell, fillers and allergens appear here.

Check with a professional
