What it is

Kelp extract powder is made from brown seaweed, a type of marine algae. The kelp is dried and then processed to extract its beneficial compounds, which are then powdered. It is commonly used as a source of natural flavor and nutrients.

Why it's used

Manufacturers use kelp extract powder to add a savory, umami flavor to foods, often as a salt substitute or flavor enhancer. It can also act as a natural thickener or stabilizer. It is frequently found in Asian-inspired dishes like noodles, rice products, and sauces.

Health notes

Kelp extract powder is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural source of iodine, which is essential for thyroid function. Excessive iodine intake can cause thyroid problems, but the amounts in typical food servings are unlikely to be harmful for most people. JECFA has evaluated kelp and its extracts.

Allergen info

Kelp is a type of seaweed and is not one of the FDA's nine major allergens. It does not contain gluten.
