The Company’s flagship patented nicotinamide riboside (NR) ingredient, Niagen^®, is manufactured, encapsulated, and bottled in the U.S. and is currently classified as exempt from tariffs, minimizing exposure to tariff-related risks

Niagen Bioscience, Inc. (NASDAQ: NAGE) (formerly ChromaDex Corp.), the global authority on NAD+ (nicotinamide adenine dinucleotide) with a focus on the science of healthy aging, reaffirms that the manufacturing of its Niagen^® ingredient (patented nicotinamide riboside or NR) and Tru Niagen^® and pharmaceutical-grade Niagen^® products remain resilient amid the recently enacted global tariffs.

Manufactured in the U.S. by the Company’s partner, W.R. Grace, Niagen is rigorously tested, encapsulated, bottled, and packaged domestically as Tru Niagen using premium materials. With only a small percentage of materials sourced internationally, the cost to manufacture final Niagen products remains largely insulated from global price volatility.

“We made the decision to build a U.S.-based supply chain for Niagen to safeguard long-term resilience, trust, and quality,” said Rob Fried, CEO of Niagen Bioscience. “That foresight is proving valuable now. We remain confident in our ability to deliver Niagen products to customers and long-term stability to shareholders.”

Currently, most vitamins—including nicotinamide riboside (NR)— remain exempt from the recently enacted tariffs. This exemption enables Niagen Bioscience to continue international operations without disruption. In 2024, approximately 24% of the Company’s revenue came from international sales, with over 12% attributed to A.S. Watson in Hong Kong—a duty-free market not subject to tariffs. As a result, this key international revenue stream remains unaffected by recent trade policy changes.

At this time, the Company anticipates no interruption in its ability to deliver Niagen products or maintain costs and pricing.
