The Institute for Feed Education & Research (IFEEDER), working with market intelligence firm Kemiex, has released "Feed Additives: A Primer on Precursors," an assessment that traces the upstream supply chains behind vitamins and amino acids used in U.S. animal feed and pet food.

The report extends IFEEDER's earlier research documenting U.S. reliance on imported vitamins and amino acids. Instead of stopping at finished additives, the primer examines the precursor materials, intermediates and industrial inputs required to produce them — a layer of the chain that feed buyers rarely see but that can determine ingredient availability and cost.

"The precursors assessment looks upstream of the vitamin and amino acid supply chain, giving the feed and pet food industries a more complete picture of the complexity that could affect ingredient availability," said Lara Moody, IFEEDER executive director. "Understanding the interconnected chemical and industrial supply chain for vitamins and amino acids equips industry leaders with the knowledge necessary to make decisions about the design, opportunities, risks and resilience of essential supply chains."

The report's central finding is that shared chemical inputs and infrastructure cut both ways. They improve manufacturing efficiency, but they also create interdependencies: a disruption affecting a single precursor, facility or production pathway can ripple across multiple manufacturers and finished products. COVID-19, geopolitical and trade shifts, drug shortages and market concentration have all raised scrutiny of these structures in recent years.

Niacin illustrates the problem. The vitamin B3 nutrient supports animal health, feed efficiency and productivity, and producers make it through chemical synthesis that depends on beta-picoline — itself a byproduct of pyridine production. The pyridine value chain also feeds herbicide and pharmaceutical manufacturing. Shifts in those unrelated markets can therefore move input costs and availability for niacin producers, and ultimately for feed formulators.

The assessment shows vulnerabilities vary widely by product, driven by the complexity of each upstream chain, the chosen production route and whether alternative chemical inputs or manufacturing pathways exist. Integrated industrial parks, where manufacturers share inputs, utilities and infrastructure, deliver efficiencies but create dependencies stretching across multiple products and producers.

"Understanding nutrition and health supply chains requires looking beyond where a finished vitamin or amino acid is produced to the inputs and processes that make that production possible," said Stefan Schmidinger, partner and head of market research at Kemiex. "Our evaluation shows how interconnected these supply chains can be, with critical precursors, intermediates and infrastructure often shared across manufacturers, products and even industries. Mapping those connections provides greater visibility into where opportunities and vulnerabilities may exist. Kemiex presents this primer for IFEEDER as a basis for further discussion and research."

The report also acknowledges practical limits to transparency: proprietary manufacturing processes, supplier confidentiality and competition law all restrict how far buyers can trace their chains. Even so, the authors argue that mapping these connections helps stakeholders identify where added visibility, supplier diversification and collaboration would strengthen preparedness for future disruptions.

The context is large. Animal and human nutrition and health sit within a global chemicals and life sciences sector generating more than $5.5 trillion in annual turnover, spanning hundreds of thousands of products and molecules across layered supply chains. IFEEDER, founded in 2009 as a 501(c)(3) public charity, says the primer is part of its continuing effort to supply independent, science-based research on the resilience of the U.S. animal food supply chain.

The full report is available on ifeeder.org, and IFEEDER and Kemiex frame it as a starting point for deeper investigation into specific precursor markets.
