Case study

How 3PL delivered fast, compliant UK fulfilment for Spectrum Supplements

Spectrum Supplements is a global supplier of vitamins, supplements and nutritional products for children and adults with special educational needs and disabilities. It specialises in premium brands, hard-to-find products and clinically trusted formulations.

The business operates across multiple sales channels, including its own eCommerce website and retail distribution through partners, including Holland & Barrett. This model requires a flexible fulfilment approach, capable of managing both direct-to-consumer (D2C) orders and retail replenishment efficiently some of which are temperature sensitive.

As demand for its products increased in the UK, the USA business sought to improve delivery speed and reduce reliance on overseas fulfilment from its main distribution centre in the USA. Longer cross-border lead times were impacting customer expectations, particularly as demand for faster domestic delivery continued to rise.

Spectrum Supplements required a multi-channel fulfilment solution that could store stock closer to its UK customers while maintaining strict handling standards for health and food-grade products, including temperature control.

A UK fulfilment solution for supplements and vitamins

With a proven track record of successfully supporting international supplement and vitamin brands in the UK market, we were chosen as Spectrum Supplements’ UK fulfilment partner.

Working closely with the company’s logistics team, we implemented a multi-channel solution designed to improve speed, compliance and operational control:

UK-based stock holding: Inventory held in one of our UK fulfilment centres to remove reliance on international shipping and reduce delivery times.
Temperature-controlled and cool chain handling: Bespoke processes introduced for selected SKUs requiring controlled storage.
ISO 9001-accredited quality management system: Ensuring consistent handling standards for vitamins and nutritional supplements.
Specialist packing processes: Including protective packaging and cool packs to maintain product integrity.
Real-time visibility and traceability: 3PL Fusion provides live stock, order and performance data alongside full product lifecycle traceability, which is essential when handling and processing goods for human consumption.

This solution enabled Spectrum Supplements to transition from cross-border fulfilment to a fully scalable UK-based operation with seamless service delivery.

Scalable UK fulfilment for long-term growth

Our UK-based fulfilment operation has given Spectrum Supplements a more stable and scalable foundation for growth, while improving both delivery performance and operational efficiency.

With inventory now positioned closer to its UK customers, the business has been able to expand into new sales channels, such as Holland & Barrett. As demand in the UK continues to grow, the setup provides the flexibility to scale easily, supporting increased order volumes and continued sales channel expansion without disruption.

Spectrum Supplements has been a 3PL Flex customer since 2014 and the partnership has continued to evolve alongside the business, supporting its expansion in a fast-growing market.
