comme-ci comme ca

I have purchased this product multiple times, to take in conjunction with other things when I have a cold. The thing is, I have to take more than the recommended amount to notice it actually working. Granted, this may be because I take it when already sick instead of on a continuous basis (but I take too many other pills to add another to my daily regimen).

Not sure if that is the nature of the product or if a different brand would make a difference. Or, again, if taking this daily would change the outcome.

I suppose I would recommend this with the caveat that more than the DRA may be needed.
