Internal Powder is a special blend of dark brewer’s yeast, garlic,
B vitamins, minerals and special nutrients that work together
synergistically and more effectively for fleas than yeast and garlic
alone. Taken orally, the Powder produces an odor that is undetectable by
humans and is loathed by fleas and ticks, mosquitoes, and black flies.
Taken regularly, the Internal Powder makes your animal less attractive
to infestation. All ingredients are human food grade with no
insecticides, chemical preservatives, salt or sugar. IT WORKS! Over 20 years of testimonials prove this product really works.
