Is it OK to see white specks in a diet iced tea mix?

Seeing white specks in a diet iced tea mix can be normal, as they may be undissolved sweeteners, flavoring agents, or even natural plant particles. However, if the specks appear unusual or the mix has an off smell or taste, it's best to err on the side of caution and avoid consuming it. Always check the expiration date and storage conditions as well. If in doubt, consult the product's packaging or manufacturer.
