Just wondering if anyone has any experience of using Lugols iodine drops. Mine arrived this morning. I put a drop on my wrist earlier. Am I correct in thinking that if it disappears within a few hours, a deficiency is indicated but if it's still there after 24 hours, no deficiency is indicated?
On a lighter note, I've already had two people ask me how I bruised myself! 😀
Best wishes to all my NDT friends!
