What should be avoided if a client has an allergy to Iodine?

If a client has an allergy to iodine, it is essential to avoid substances that may contain it or share similarities with it, particularly in regards to marine life. Algae, specifically certain types such as seaweed, can contain iodine. In some cosmetic and skincare products, algae is used for its beneficial properties, but it often comes from marine sources, which can lead to exposure to iodine.

It is crucial to recognize that iodine allergies can cause allergic reactions that range from mild to severe. By avoiding algae, the risk of inducing a reaction is minimized. Sea salt, while derived from the ocean, is often just sodium chloride and does not typically contain significant amounts of iodine unless it is specifically iodized. Lemon and mint are plant-based and do not have any relation to iodine or iodine-containing compounds, making them safer options for individuals with iodine allergies. Therefore, the most appropriate substance to avoid in this context is algae due to its potential iodine content.
