It really works!

I find this product great. If I feel like I am coming down with something, I start taking Defense Plus. It really works!

Thanks for your feedback!

Like a natural antibiotic!

These have worked just great for me over the years, so I keep them on hand for those times when I feel a flu or other infection coming on. Fair price and on-time delivery from the supplier, too!

Thanks for your feedback!

Have been flu for 1 week, after took the pills (2 in the morning and 2 at night), the flu gone within 4 days. Worked well for me.

Thanks for your feedback!

Excellent product for immune systems

Posted by iHerb Customer on August 22 2017 | Verified Purchase

When myself or family has early symptoms of flu, we take six tablets through out the day. And keep taking 4-6 the next few days. Typically, the cold or flu would be suppressed without turning to a full boom one. It works most of the time. Highly recommended.
