RLC Laboratories

RLC Laboratories is a specialty pharmaceutical company that focused on the treatment of hypothyroidism and endocrine disorders. The company gained prominence for its natural desiccated thyroid (NDT) medications, specifically Nature-Throid and WP Thyroid, which are derived from porcine thyroid glands. In addition to its prescription drug line, RLC offered a suite of dietary supplements designed to support adrenal and thyroid function, such as a-Drenal and i-Throid. Following a series of comprehensive product recalls in 2020 due to potency issues and subsequent regulatory scrutiny from the FDA, the company's manufacturing operations for its core thyroid products have been largely suspended. Consequently, its primary medications are currently unavailable in the United States market.
