Have not, but I recently ordered one thats coming in the mail any day now. Will be nice to really see if im zink defficient or not, have always thought so because of acne, general slow wound healing, white dots on nails etc.

I know a few people on here are supplementing with zinc. I found this test pretty interesting. Essentially you swish a zinc solution in your mouth and if you are zinc SUFFICIENT you will sense an immediate bitter taste. In contrast, if you are some level of zinc deficient then you will sense a taste ranging from nothing to a milder bitter taste.
Anyone tried this before?
Edit: To include criticism that the test can measure false positive or false negative depending on the testers overall taste sensitivity.

I've done the test with Thorne brand Zinc Sulfate, which can be found at iHerb. I am definitely zinc deficient (slow healing, white spots on nails, persistent acne, thyroid and digestive issues), and the test confirmed this; a shot glass of the solution held in my mouth for 30 seconds only produced a very faint baking soda taste. Most of what I've read has claimed this test is more accurate than tests of serum zinc levels, so I think it's a good way to determine if you need to supplement or not.
Sorry Grizz. I haven't tried it yet. I just heard about it on Robb Wolf's podcast and googled to check it out.
It looks like a 0.1% zinc sulphate solution is the best concentration. I'm sure that you can also use zinc picolinate. Basically just find a capsule that only contains zinc, open it, pour it into the right volume of water and stir till it is dissolved.
I'm probably going to get some zinc at the store tonight. I'll update here if I try it.![]()
Claims are nice, but where is the research showing that the test has any validity at all?
Here's what I use for oral zinc status testing:

At one point, I had a cite that supported the correlation between the 'taste perception of zinc in solution' and 'zinc tissue status'. For the life of me, I can't find the reference. Anyone?
