Query: Only downside is the powder residue

This product is just fine. The only thing I didn't like was the white powder inside. I dumped everything out and blew the dust away (cough). But that took care of it. I like that it only has 22 mg, and the tablets are small. I haven't noticed any bad taste or odors. I will continue to buy this product unless I find another brand (of same type) at a cheaper price.I will post pictures of the label showing the nutritional info, because I hate shopping on Amazon when I can't see the details.
