The report provides examples of why supply chains need to be examined beyond the finished product. For example, niacin (i.e., vitamin B3) is an essential nutrient involved in animal nutrition and energy metabolism, supporting animal health, feed efficiency and overall productivity. Niacin is produced through chemical synthesis, and its production relies on beta-picoline, a key precursor, as a byproduct from pyridine production. The pyridine value chain is also connected to other chemical markets, such as the production of herbicides and other pharmaceuticals. As a result, changes in these markets can impact upstream inputs needed for niacin production and potentially affect production costs and availability.
