Strength % is simple if we understand what Lugols is. Learn more about Lugols in general at whyiodine.com/lugols
The strength % situation
Lugols comes in different strengths.
This strength can be looked at the same way we see a strong or weak glass of alcohol. Its the same amount of liquid, but a lower strength drink may get us tipsy while a stronger strength drink may knock us on our butt.
Or the sweetness of a cake. We get the same size bite of cake, but a cake with more sugar, tastes much sweeter than the same bite of cake that had less sugar used in it’s creation.
Lugols is 1 part Elemental Iodine(I2) and 2 parts Potassium Iodide and water. No matter what the strength is, it’s always 1 part of I2, 2 parts of Potassium Iodide. The strength changes as the ratio of water vs the total iodine changes.
Lugols solution/recipe gained popularity because it allows us to suspend more iodine into a usable form. Some weird chemistry comes into play and causes only certain amounts to remain stable(mixed). This is where we get a handful of common strengths like 2, 4, 5, 23, 46 etc. Those strengths just happen to be ratios that worked, but remember, all of these are still 1 part I2 to 2 parts Potassium Iodide, anything outside of that 1:2 ratio of those two ingredients, is not Lugols (and probably won’t suspend properly).
Using different strengths
Unless you are making your own Lugols, the only thing you need to worry about is what strength % your Lugols is.
If we had two drops side by side, one drop of 2% and one drop of 4%. The drop of 2% contains 2.5mg of combined Iodine(i2) & Potassium Iodide. And the drop of 4% has 5mg of total combined Iodine. Or, two drops of 2% contains the same amount of iodine as one drop of 4%.
So both drops are still Lugols Iodine Solution, but one contains twice as much “Strength” as the other. This allows us to find a good strength that works well for the amount of iodine we would like to consume.
I created http://dropulator.com to help ease a little confusion with iodine dosage amounts. Just plug-in the strength % of your Lugols and adjust the drops till you find your dose, or see how much of a dose you might get with X amount of drops.
So which one do I use?
How much iodine do you want?
2.5mg to start slow and learn how to balance nutrients like I did?
Or 50mg because you see this as a race?
All the different strengths do is helps us get to our dose easier. We can still get to any dose with any strength either by using more of a weaker blend, or diluting a strong blend.
