Vitamin D markets in the United States shifted from a soft February trend to a modestly firmer tone by late March, as geopolitical risk premiums and higher energy costs encouraged suppliers to raise offers. Early-March trading remained largely stable, with buyers relying on just-in-time purchasing programs and existing inventories providing adequate short-term coverage. By mid- to late March, however, trading activity reflected sentiment-driven mark-ups and precautionary restocking by distributors concerned about possible logistics disruptions. Demand across major end-use sectors remained generally subdued, indicating that headline price increases were driven more by market risk perception than by any significant improvement in physical consumption. In human nutrition and dietary supplements, retail sales increased modestly month on month, while premix demand stabilized as formulators continued drawing down stocks. Animal-feed premix demand also remained soft amid a slight year-on-year decline in poultry placements. On the supply side, elevated feedstock and energy costs continued to pressure margins, while tensions involving the US, Israel, and Iran supported firmer quotations and upward price expectations.
