Hi Roni
I'm afraid I can't really help you. I have Beardies, but don't give them any supplements. One of them is such a fussy eater, she can smell anything different a mile off. I don't groom every day, I do their beards every couple of days, a thorough groom once per week, wash their whites for shows, but very rarely give them an all over bath (lucky if it's once/twice per year). This seems to keep the outer coats in the correct harsh condition they should be.
Sorry I couldn't be of much help, but i'm sure someone will be along soon who can.

Hi Sarah,
I am no expert on grooming, or keeping a Beardies white, white by any stretch of the imagination. I use a shampoo called Bright White (by Ring 5), when I bathe the whites for a show. IMO you shouldn't bath them too often, as it strips the natural protective oil from the coats. On the whites, if they are washed too often, they seem to actually get browner, quicker! I have known some people use a form of bleach!!!, but I never have. My Beardies don't have the whitest beards around, believe me!
