Keeps my flus away

Posted by tootze on Apr 18, 2016

I have been taking this product for years to aid my sinus problem. Used to wake up with running nose, now no more. This helps me keep the flus away when taken regularly. Highly recommended as health maintaining supplement.

Good for day to day

I prefer the Capsule version since the veggie tabs are a bit big to swallow, but it seems they only offer in small bottles? I tried these for a month and they are great in flu season, I don't get sick as easily as before. Now I stock them in large quantities.

Works really well, but the tablets are huge.

i use vitamin c every day to help me maintain a good health. Ester-c was recommended to me since you can take huge amounts without toxicity. it works great when you start taking it in the first signs of any sickness.

Oops. meant to order capsules. Don't like these that much. Order the caps, as they're much better and easier to swallow and digest
