Insulin

Question from Sydney, Australia:

I was wondering if insulin is coloured.

Answer:

Insulin is either clear or cloudy depending on the type of insulin but none is colored that I know of.

Additional comments from Dr. Bill Quick:

Of course, the container’s label, or the cap, may be color-coded, according to regulations set up by the country in which it is sold.
