Vibrance is Potassium Iodide, it does have Potassium in it (K) but not enough to raise the levels without raising iodine too high. It’s comparable to KZ’s Potassium Iodide Fluoride (PIF).

If you are looking for a K additive check out Warner Marine’s Balanced Ion Potassium supplement -

Vibrance is similar to K-balance in Zeovit?

I should buy a new K-balance but if it is similar and better than K-balance, I wanna try this…

Could you tell me where I can buy this?
