Who is IN-X a good fit for?
IN-X is well suited for adults looking for herbal support during cold and flu season, those wanting to promote respiratory and lung health, or anyone interested in a whole-body cleansing formula. If you are pregnant, nursing, or taking medication, it's always a good idea to check with your healthcare provider before starting any new supplement.

I use IN-X with VS-C, Viral immune formula when I feel a sinus infection trying to come on me. If I do not address this immediately it usually goes into sinus/throat infection. You cannot go wrong with using IN-X.

Hope it will help my immune system. I’ll know more in the fall and winter.
- Marianne McGinnis9/15/2025Can't be without it!
I have relied on IN-X for many years. It's been close to 20 years ago that I was tested by a Nature's Sunshine consultant when I had a terrible cough, leftover from the flu, that lingered for months. I tested as needing this particular combination; and IN-X along with other Nature's Sunshine herb combinations helped me to heal within a few weeks. I have continued to keep it on hand, and use it whenever I start with a sore throat or congestion. As long as I begin it early, I don't develop a cough. It helped me through the worst of Covid and since then. I truly can't be without it in my arsenal of healing herbs!
