Lugol's in orange juice v. SSKI

I have a bunch of Lugol's 2% and would rather not spend money on SSKI at this point. Here's my math (please correct if I'm wrong):

SSKI = 25mg Iodide per drop
Lugol's 2% = 2.5 mg Iodine + Iodide per drop
Lugol's 2% in oj = 2.5 mg Iodide per drop

So, by my calculations, 10 drops of Lugol's in oj should be roughly equivalent to 1 drop of SSKI . Is that correct, or does the SSKI have some other advantage that Lugol's in oj does not? Tweet
