The full guide
What is L-Isoleucine Powder?
This product is a single-ingredient L-Isoleucine supplement in powder form. The packaging is 250 g, and each serving provides 1 g of L-Isoleucine. The product is described as vegan and gluten-free in the title, and the ingredient list is a single item: L-Isoleucine.
Gluten safety and labeling
The product is labeled gluten-free and contains no gluten ingredients per the data provided. There are no documented third-party gluten certifications (e.g., GFCO) in the supplied information. Cross-contact policies are not documented, so the gluten-free status relies on labeling rather than batch-level certification. A claim of manufacturing in a cGMP-compliant facility appears in some listings, but it is not guaranteed for every listing.
Taste, mixability, and practical use
Taste can be unpleasant for some users, as noted in reviews. Solubility and mixing may be inconsistent—some users report quick dissolution while others find solids or slow mixing. The product is unflavored, so it is typically mixed into shakes, water, or regimens where a flavor-masked option is not provided.
Value, best uses, and who it’s for
The price is listed at $18.97 for 250 g, yielding about 250 one-gram servings. Price per serving is roughly $0.076, placing it in a mid-range tier for bulk amino acids. It is best for athletes or individuals seeking a pure, single-ingredient L-Isoleucine supplement that is vegan and gluten-free; it may not be ideal for those who want a flavored product or a multi-ingredient BCAA blend.
