Seawater with a single ingredient: 100% seawater. Its Bag in Box (BiB) presentation includes a dispensing tap and is described as a practical and convenient format for the kitchen. It is proposed as an alternative to common salt and to add flavor and new textures to foods, adjusting the proportions in each preparation. The title identifies the product as 5L, but the description states a 2-liter Bag in Box. These capacities do not match and should be confirmed before purchase. The original text distinguishes the hypertonic preparation, with 100% seawater, from the isotonic one, diluted with fresh water. It also mentions 2 “shots” or 2 single-dose servings in its 20ml format and, for the isotonic preparation, up to 2 liters daily. These references are included as seller information, not as health advice or as the content of the advertised package. No nutritional data, origin, or specific storage conditions are provided.
