Still testing...

I have taken these for a little less than 2 weeks and so far notice a very slight improvement. I do like that they do not have to be refrigerated. Had I taken for a longer period of time and seen big progress my stars on the review would likely increase.

2nd bottle for us

We have heard using vitamin C powder, is better than pill form. We put it orange juice. We use all immune boosting products to keep our immune system healthy. I do like this product very much. No after taste or upset stomach using it. We recommend it!
