Formulate Without Synthetic Dyes | CapsCanada

The FDA has already banned Red No. 3 and announced a regulatory roadmap to eliminate other synthetic dyes from the U.S. food supply. This includes revoking authorization for Citrus Red No. 2 and Orange B, and working with industry to phase out FD&C Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, Blue No. 2, and Green No. 3 by the end of next year.

While targeted at food products, this regulatory pressure has direct implications for supplement brands, especially those using synthetic dyed capsules as part of their delivery systems. Reformulating with natural alternatives is becoming more common and those who act now will have a clear operational advantage.

Changing Capsule Colors in a Shifting Regulatory Landscape

Reformulating existing products while maintaining capsule integrity demands precise control over color stability, shell performance, and fill compatibility.

As global standards become more stringent and clean label expectations rise, brands must:

• Adapt formulations without compromising capsule disintegration, machinability, or stability
• Replace synthetic-based dyes with natural alternatives that perform reliably under production conditions
• Ensure compliance with international regulations, such as the EU ban on TiO₂ and anticipated FDA color or ingredient restrictions
• Secure a dependable supply chain for high-quality, plant-based pigments at commercial scale

At CapsCanada, we offer capsule solutions tailored to meet these demands.
