  • To evaluate zinc status.5
  • Developed by Dr Bryce-Smith of London.5
  • Contains ten zinc tests per bottle.


Evaluation: Responses to tasting 10 mL of the solution normally fall into one of the following four categories:

  1. No specific taste or other sensation is noticed, even after the solution has been kept in the mouth for about 10 seconds.
  2. No immediate taste is noted, but after a few seconds a slight taste variously described as 'dry mineral', 'furry' or 'sweet' develops.
  3. A definite, though not strongly unpleasant taste is noted almost immediately and tends to intensify with time.
  4. A strong and unpleasant taste is noted immediately.

Category 1 is the poorest zinc status, while category 4 is optimal.
