NRTC-103™ is a U.S.-manufactured dietary supplement designed to faithfully replicate the original Neurotec multi-herbal capsule formulation studied in placebo-controlled clinical trials and described in peer-reviewed scientific literature. It contains the same three dried herbal extracts—Rosa canina, Urtica dioica, and Tanacetum vulgare—in the exact same amounts, and is standardized to match the original manufacturer’s chemical specifications and identifying characteristics, making it interchangeable and comparable to Neurotec in every meaningful, measurable way.

Until recently, Neurotec had no substitutes and was not legally accessible outside its country of origin due to export restrictions, despite growing international interest driven by the published research. In late 2024, an FDA-registered manufacturing facility in Colorado (TG Labs Inc.) began producing NRTC-103 to make this formulation domestically available in the United States.

NRTC-103 is sold as a non-official replication of Neurotec, intended solely as a dietary supplement and presented without disease or treatment claims; it is not intended to diagnose, treat, prevent, or cure any disease, and should be used only in a manner consistent with its definition as a dietary supplement.
