RLC Labs Recalls Nature-Throid Tablets Due to CGMP Deviations

RLC Labs Inc. is recalling Nature-Throid tablets because they were manufactured under conditions associated with subpotency. The recall covers all lots with expiry dates between October 2020 and July 2023.

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: The recall is classified as FDA Class II, which typically involves a temporary or medically reversible adverse health consequence. The source text does not report any hospitalizations or serious injuries, and the hazard is related to manufacturing conditions rather than a confirmed high-risk pathogen or structural defect.

Plain-English summary

The recall is due to Current Good Manufacturing Practice (CGMP) deviations, specifically because the tablets were manufactured under the same conditions as those found to be subpotent.
