Agar is a gelling substance obtained from seaweed. The figures here describe dried agar after it has been soaked and drained, rather than agar in its dry form. It consists mainly of water and provides minerals, including calcium, iron and magnesium. Per 100g, it contains 7 kJ of energy, 110mg of calcium, 3.5mg of iron and 75mg of magnesium.
Calcium helps maintain bones and teeth, while iron is needed to make haemoglobin, which carries oxygen in the blood. Magnesium contributes to normal muscle and nerve function. This form of agar contains little fat or salt, with only traces of sugars and saturated fat. Full nutrient figures are in the tables below.
