Usually any health food store carries Liquid Iodine.
You can purchase Liquid iodine for about 11 dollars a bottle, it lasts for months. Then there is always the Famous LUGOL’s iodine

I do buy Nascent iodine, but it is a bit expensive, but a bottle last 3 months or more. it’s 36 dollars. Do your research on it. also Dr Brownstein who wrote a book on iodine says this:Dr. Brownstein feels iodine is the most misunderstood nutrient. He feels it is impossible to achieve your optimal health when there is iodine deficiency present. This book provides information on how iodine therapy can help:
•ADHD
•Autism
•Breast, Thyroid, Ovarian and Uterine Cancer
•Detoxification
•Fatigue
•Fibrocystic Breasts
•Graves’ Disease
•Hashimoto’s Disease
•Hypothyroidism
•Improve the Immune System
Iodine deficiency is occurring at epidemic rates. Over the last 40 years, the U.S. National Health and Nutrition Examination Surveys have found iodine levels have declined over 50% in the U.S. population.
