I really like these pills. They are easy to swallow and don't have an after taste. I am looking forward to a better immune system from these.

Great boost to my immune system - highly recommended!

I can't prove that this product did it but it likely was a factor, so I'm going to keep on taking it. The only issue I'll mention is that there is a noticeable odor and taste of garlic (one of the ingredients) when you take it. So don't take it with chocolate milk!

The best Vitamin C on the market! ZAHLER uses PureWayC which is absorbed in the body much better than all other Vitamin C’s. Haven’t gotten sick in years and I take this daily.

Works very good

Great Product at a great price.

This product could not arrived at a better time. Friday afternoon, I broke out with a cold sore.... I get them like once a year, if that. My immune system is usually good enough to keep them at bay...but recently, i've been compromised. I have two autoimmune diseases, and sometimes, I just go into super flare up mode. When my immune system is surpressed, i'm more likely to have a flare up and with this flare up, my lip decided to get a big, fat, pussy, ugly cold sore. I have some lysine ointment, which I used all day on Friday and put on a good amount before I went to bed. Saturday morning I woke up, and it seemed like it was TWICE the size....uggh.. I have to teach class. I'm not a fan of this, and i'm not advising anyone to do this, but I sanitized a needle and punctured my cold sore -- took a cotton swab with alochol (ouch) and held it on the ugliness. THis reduced the size/look of the cold sore enough for me to appear in public. The cold sore is just above the crease on the right side of my upper lip.....If I smile, you can't tell that it's there. I smiled all class long. By the time I got home from class, the pussiness I removed had returned -- doubled! On my porch was a package from Amazon --- and inside that package was a bottle of Zahler Abreve. It sounds like Abreva, the cold sore stuff, right!. Anyway, I checked out the ingredients, Astragalus, Echinacea, Elderberry Extract, Garlic, Vitamin B5, and Vitamin C. Sounds like this should at least boost my immune system and help it to fight this virus that's causing this cold sore. Recommended dosage, 6 pills (WOW!). I took 2 in the afternoon and 2 more before I went to bed. I woke up and the cold sore didn't grow, and it looked like my skin below the cold sore started growing. If you ever had a cold sore before, you know that the skin below the sore usually doesn't grow until the cold sore begin to dry up. This is Sunday, two days after the initial breakout, and my cold sore is barely noticable-- even with my vanity lights. Popped two more pills this afternoon and will take two more this evening. I truly believe that these pills have greatly reduced the healing time of this nastiness on my upper lip. As you've noticed, I only took 4 of the recommended 6 pills in a day. I have a very sensitive system, and I usually have to take half the recommended dosage when it comes to supplements -- and i still get the desired results. So, this bottle should last me more than 15 days. After my breakout clears up, I plan to take Zahler's Immune Defense daily to build my immune system back up and hopefully avoid another breakout.I receive this product at a discounted rate to test and leave a product review.
