The National Administration of Medicines, Food and Medical Technology (ANMAT in Spanish) and the Secretariat of Agriculture, Livestock and Fisheries, thru Joint Resolution 3/2025, incorporate powdered Euglena gracilis algae as an ingredient in dietary supplements in the Food Code.

It must meet the following characteristics:

Appearance: Homogeneous, free-flowing powder, free from foreign matter.

Color: Yellow

Odor: Characteristic of algae

Beta-glucan: Greater than or equal to fifty percent (≥50%)

Protein: Greater than or equal to fifteen percent (≥15%)

Total dietary fiber: between sixty-one percent (61%) and sixty-three percent (63%)

Humidity: maximum SIX PERCENT (6%)

Ash: maximum TEN PERCENT (10%)

Metals (maximum):

Lead: 0.5 ppm

Cadmium: 0.5 ppm

Mercury: 0.05 ppm

Inorganic arsenic (As-in): Maximum 1.0 mg/kg. As a first choice, the total arsenic (As-tot) analysis can be performed. If the total As (As-tot) concentration is below the maximum limit (ML) for inorganic As (As-in), no further testing is required and the sample is determined to comply with the ML. If the total As concentration (As-tot) exceeds the maximum limit (ML) for inorganic As (As-in), additional tests must be performed to determine whether the As-in concentration exceeds the ML.
