L-Arginine Alpha Ketoglutarate (AAKG) 2:1 Powder

Bioprecis supplies L-Arginine Alpha Ketoglutarate 2:1 (AAKG) powder in bulk to sports nutrition, nutraceutical and supplement manufacturers across India. AAKG is an amino acid salt that pairs two molecules of L-arginine with one molecule of alpha-ketoglutaric acid. Because L-arginine is the body’s precursor for nitric oxide, AAKG is one of the most widely used ingredients in pre-workout and “pump” formulations. Every batch is supplied with a Certificate of Analysis, and our team can share specifications and bulk pricing on request.

What Is L-Arginine Alpha Ketoglutarate 2:1?

L-Arginine Alpha Ketoglutarate (AAKG) is a salt formed from two compounds:

• L-arginine, a conditionally essential amino acid and the substrate that nitric oxide synthase (NOS) enzymes convert into nitric oxide (NO) and L-citrulline.
• Alpha-ketoglutarate (AKG, 2-oxoglutarate), an intermediate of the Krebs (citric acid) cycle involved in energy and amino acid metabolism.

The “2:1” refers to the molar ratio: two parts L-arginine to one part alpha-ketoglutarate. Compared with the 1:1 form, the 2:1 ratio delivers more L-arginine per gram (about 70% vs about 54%, calculated from molecular weights), which is why it is the more common choice in sports nutrition formulas.

Applications of AAKG Powder

Manufacturers use AAKG in:

• Pre-workout and “pump” formulas: as a nitric oxide precursor ingredient, often alongside L-citrulline, beta-alanine or caffeine.
• Sports nutrition powders: intra-workout and endurance blends.
• Nutraceutical and dietary supplements: amino acid and nitric oxide support products.
• Dosage formats: powders and drink mixes, capsules and tablets.

Product claims on finished goods are the brand owner’s responsibility and must follow FSSAI nutraceutical regulations in India or the rules of the destination market.

Why Formulators Choose AAKG 2:1

• Higher arginine load per gram than the 1:1 salt, which saves space in multi-ingredient scoops.
• Two functional parts in one ingredient: an L-arginine source plus alpha-ketoglutarate, a Krebs cycle intermediate.
• Recognised label name: “AAKG” is a familiar term for sports nutrition consumers.
• Documented quality: batch COA, plus specification and safety data sheets on request.

AAKG vs L-Arginine HCL vs L-Arginine Base vs L-Citrulline

Ingredient	What it is	L-arginine content (theoretical)	Typical use
L-Arginine Alpha Ketoglutarate 2:1	L-arginine salt of alpha-ketoglutaric acid	~70%	Pre-workout and pump formulas
L-Arginine HCL	Hydrochloride salt	~83%	Supplements, sports nutrition, functional foods
L-Arginine Base	Free amino acid	100%	Supplements; also used to adjust pH
L-Citrulline	Amino acid the body converts into L-arginine	Not an arginine salt	Pre-workout, often combined with AAKG

Arginine percentages are calculated from molecular weights, not from a batch COA.

Frequently Asked Questions

What is L-Arginine Alpha Ketoglutarate 2:1 (AAKG)?

AAKG 2:1 is a salt made of two molecules of the amino acid L-arginine and one molecule of alpha-ketoglutaric acid. It is a white crystalline powder used as an ingredient in sports nutrition and nutraceutical products.

What is AAKG used for?

AAKG is mainly used in pre-workout, “pump” and nitric oxide formulas. L-arginine is the substrate the body uses to make nitric oxide, so manufacturers add AAKG to products positioned for training and circulation support.

What does 2:1 mean in AAKG?

It is the molar ratio of L-arginine to alpha-ketoglutarate. The 2:1 form contains roughly 70% L-arginine by weight (calculated), compared with roughly 54% in the 1:1 form.

What is the difference between L-Arginine and AAKG?

L-arginine is the free amino acid; AAKG is L-arginine bound to alpha-ketoglutarate. AAKG supplies less arginine per gram but adds alpha-ketoglutarate, a Krebs cycle intermediate, and is the form most associated with pre-workout products.

L-Arginine HCL vs AAKG: which should I use?

L-Arginine HCL gives more arginine per gram (about 83%), while AAKG adds alpha-ketoglutarate and is the more recognised name in sports nutrition. The choice depends on your label positioning, cost per serving and formula space. See our L-Arginine HCL page for its specification.

Can AAKG be combined with L-Citrulline?

Yes. AAKG and L-citrulline are commonly formulated together in pre-workout products, because the body converts L-citrulline into L-arginine.

Is AAKG effective for performance?

Research results on AAKG and exercise performance are mixed, so finished-product claims should be supported by evidence and comply with FSSAI rules. We supply the ingredient with full specifications; claims on finished goods are the brand owner’s responsibility.

What is the CAS number of L-Arginine AKG 2:1?

The CAS number of L-Arginine alpha-ketoglutarate 2:1 is 5256-76-5.

What is the minimum order quantity for AAKG?

The MOQ for bulk supply is 25 kg. You can also order a 1 kg pack online.

What is the price of AAKG powder per kg?

The online price shown on this page is for a 1 kg pack. Bulk pricing depends on quantity, packing and delivery location; request a quote with your required volume.

Which documents do you provide?

A batch-specific Certificate of Analysis (COA) is supplied with every batch. The Technical Data Sheet (TDS) and Material Safety Data Sheet (MSDS) are available on request.

What is the shelf life and how should AAKG be stored?

Shelf life is 24 months in the original sealed packing. Store in a cool, dry place away from moisture and direct sunlight, and reseal opened containers tightly.
