E404 Calcium Alginate

What is Calcium alginate (E404)?

Calcium alginate (E404) is a derivative of alginic acid found in seaweed, used as a thickening, gelling, or stabilizing agent. It forms gels when in contact with calcium ions, making it ideal for products like jams, fruit preserves, or some dairy items.

Why do I have an intolerance?

Intolerance to calcium alginate can occur if your digestive system reacts adversely to its seaweed origin or calcium content. Symptoms might include abdominal discomfort, gas, or diarrhea. Some people are more sensitive to seaweed derivatives, resulting in an inability to tolerate even small amounts.

What can I do about it?

To manage intolerance, read food labels carefully to identify and avoid calcium alginate-containing products. Consider cooking more at home, using natural thickeners like chia seeds or cornstarch as alternatives. Gradually eliminating processed foods from your diet may also help to avoid exposure to this additive.
