What this means for you

Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.

Our severity reasoning: FDA Class III recall for subpotency, which the rubric places in the 1-2 band; a potency shortfall rather than a purely cosmetic issue puts it at Moderate.
