Immune Zoom has quickly become my go-to immune boosting tincture, especially during these times. It is a mix of exactly what my family needs. If I had a busy day out and about, or am feeling a little run down, I take this tincture blend for a couple of days or so to stay healthy. I also will combine this with the Immune Tonic and the Chest Clear if I feel that I am needing the extra boosts. These are wonderful tinctures :)
