The essential nutrient zinc is a well known immune system booster. These days it can be a little difficult to find, as more and more people become familiar with its highly regarded ability to help the body fight viral, bacterial and fungal infections. But zinc is much more for good health and strengthening the immune system.

It has a long list of benefits including accelerating wound healing, supporting digestive functioning and improving brain health. Zinc also destroys mouth odors. Rinsing with a zinc mouthwash is a great way to eliminate halitosis. It works for doggie bad breath too.

If you add a couple of drops of liquid ionic zinc to your pooches water you can improve his breath, sometimes instantly. Zinc’s odor busting properties were used in “Mum” the first commercial deodorant patented in the late 19th century.

Of course, not all body odor needs to be eliminated. In fact, some people are oddly drawn to a person’s smell, and there’s growing evidence to suggest that components of bodily secretions play an important role in determining who we’re attracted to or who is attracted to us.

As it turns out, there may be a link between immunity and the odors of attraction and repulsion. Some scientists believe that a complex immune system molecule called the MHC may contain peptides that are directly responsible for these smells. Fragrance manufacturers have already started patenting some of these peptides in hopes of creating perfumes designed to attract members of the opposite sex.
