I’ve written earlier than concerning the very low ranges of iodine in plant milks in the US and mentioned that one research (1) discovered that plant milks had about 3% as a lot iodine as cow’s milk does. Iodine is an important nutrient which is required for the thyroid gland to perform correctly. Though the iodine content material of fruits, nuts, and greens varies relying on rising situations, most of those staples of a vegan eating regimen are low in iodine (2). Cow’s milk and different dairy merchandise are a essential supply of iodine for many individuals in the US.
A colleague not too long ago contacted me and identified that Silk Soy Authentic (pink carton) is fortified with iodine. In line with the product label which I checked on October 15, 2025, a cup of Silk Soy Authentic has 15 micrograms of iodine (10% of the Each day Worth). Additionally, in keeping with the product label, Silk Soy Vanilla (additionally in a pink carton) has 15 micrograms of iodine in a cup of soymilk. The Silk web site signifies that Silk Youngsters Oatmilk Mix has 30 micrograms of iodine (20% of the Each day Worth) in a cup. I’m not conscious of different plant milks which might be fortified with iodine.
The Advisable Dietary Allowance (RDA) for iodine for adults is 150 micrograms per day so it’s unlikely that you simply’ll get all of the iodine you want from fortified Silk. Vegans also can get iodine from iodized salt, iodine dietary supplements, and sea greens though the quantity of iodine in sea greens is variable.
