I realized much later in my life that I had an iodine deficiency. I did tons of research and learned about Lugol’s 5% and how it has helped so many people. I started off with just two drops per day and felt an immediate difference in just a few days. I have never experienced something this powerful and effective. I’m less cold, my skin is healing, feeling more energy, libido has increased and I’m more in tune with my overall health. I hope this review helps others. Don’t give up, you can improve your health naturally and safely when you do your research. I trust this product and respect how strong it is so I never take too much. Be sure to have a blood panel to know your TSH, T3 and T4 before you begin dosing yourself. Start slow and steady. I eat 3 Brazil nuts for selenium, take a half teaspoon of magnesium ascorbate and a regular multivitamin. I was on the hypothyroid end of the spectrum. I look forward to having another blood panel at the end of the year to see if Lugols helped overall! Iodine is sooo important.
