Our Marigold Flower Extract is a premium-grade, highly concentrated source of Lutein and Zeaxanthin, two essential carotenoids for supporting visual health and performance. Extracted from the petals of Tagetes erecta, this ingredient is meticulously processed to yield a standardized powder with superior purity and consistency. It is specifically engineered for use in dietary supplements, functional foods, and nutritional products targeting eye health, antioxidant support, and protection against blue light.
As the original manufacturer, we ensure complete supply chain traceability, from sustainably sourced flowers to the final HPLC-verified powder, providing our clients with a reliable and effective ingredient for their formulations.

Q: Are you the direct manufacturer or a trader?
A: We are the original manufacturer and exporter of Marigold Flower Extract. Purchasing from us ensures full traceability, consistent quality, and a stable supply chain directly from the factory.
Q: What is the difference between your Lutein powder and Lutein Beadlets?
