Hello, from all that I have read I feel like I may be Iodine Deficient.
But, because I am a Black American and the tincture is clear how can I know if I am in fact iodine deficient?
Should I use lugols to do the test?
The tincture of iodine is orange colored. Hopefully, this will show up on your skin. The white iodine or yodo blanco is clear. Lugols is best when ingested. It does not have the same chemical composition as tincture of iodine.
