I have used Super Immune QuickStart for around 8 years. At that time, I used to have many colds and sore throats following years of traveling. I could barely recover before I had another cold. But over a period of a few months, this product built up my baseline health. After one year I didn't get sick anymore. I also became stronger physically. I add one scoop to my daily soyamilk/grapefruit juice drink, shake it all and that has become a stable part of my breakfast.
Over the years, my work has changed, I'm a farmer, train horses, do wood work and others. I clearly sense that my energy and the ability to fight off minor illnesses are entirely related to the daily dose of super immune quickstart. This product is a most convenient and pleasant way to secure your baseline health and a great way to ensure you have enough energy. At 64 I'm pretty fit and rarely get sick now, even on travels or despite I'm outside for many hours in all sorts of weather. I would highly recommend this product to any age group. However, probably people in my age group would feel the benefits the most. I find it so much easier to drink these "supplements" rather than having to chew many tablets. Mostly I only do one scoop per day, But if I travel abroad, I'll add one drink in the afternoon.
