Outstanding

Main highlights

•Essential Mineral Iodine: This bottle will last you - a little goes a long way. With only 2 drops per serving, you’ll receive 450 servings! The body doesn’t naturally produce iodine, so it is an essential part of any diet. Iodine deficiencies can lead to feeling fatigued and weak, dry and brittle hair, skin, and nails, and weight gain.
•Prenatal Iodine: At particular risk for iodine deficiency are those on a vegan or vegetarian diet, or those pregnant and nursing. Iodine is crucial during pregnancy, when the body requires greater amounts of iodine to support the developing fetus.
•Thryroid Health: This trace element is especially important for thyroid health, which regulates hormone production, which in turn plays an important role in metabolism. Support your body with this essential micronutrient!
•Vegan Formula: 250 mcg Iodine (as Potassium Iodide). Other Ingredients: Organic Vegetable Glycerin and Purified Water. The suggested serving of our Iodine Liquid Drops contains more than the recommended daily value for adults, except for those lactating. An individual’s iodine needs are impacted by diet. Consult with a healthcare professional to determine if supplementing iodine intake is the right choice for you!
•For Most Lifestyles: Iodine Liquid Drops by MaryRuth's are USDA Organic, Non-GMO, Vegan, Dairy Free, Nut Free, Gluten Free, Soy Free. No Added Sugar, No Artificial Colors. Made in a GMP Facility. Clean Label Project Certified. B Corp Certified.
