Introduction: From a Personal Search to a Multi-Channel Supplement Brand
Best Immune International started with a mission to provide affordable, high-quality supplements. Founder Jerry Cohen spent years researching laboratories and suppliers. After a two-year search for the right manufacturing partner, the brand launched on Amazon UK in 2019 and quickly gained traction. But rapid growth meant increasing operational complexity.
“Best Immune International is a UK-based health and wellness brand specialising in food supplements. The idea was born in 2017 when I was searching for affordable, high-quality supplements for my own family.”
– Jerry Cohen, Founder at Best Immune International
The Challenge: Managing Multiple Marketplaces
As Best Immune International expanded across marketplaces, operations became increasingly fragmented. Orders, stock levels, and product listings had to be managed across multiple platforms manually, creating a heavy operational burden. Jerry explains “our biggest hurdle was fragmented operations. We were selling on multiple platforms, and managing orders, stock, and listings manually was incredibly time-consuming.”
At the same time, another challenge emerged: Brexit. New regulations meant the UK-based business could no longer sell supplements directly into the EU without establishing an EU entity. The company needed a solution that could both streamline operations and support international growth.
To simplify operations, Best Immune International implemented Base.com as its central operational hub. With Base.com, all marketplaces are connected to a single dashboard, allowing the team to manage orders, listings, and stock from one place. Automation quickly became the biggest efficiency gain. Base.com’s automation rules route orders automatically based on criteria such as quantity, product type, or destination. “The shipping automation feature was a game-changer. It automatically sorts orders and routes them to the correct fulfilment channel without me having to touch anything.” This automation dramatically reduced the amount of manual work required to manage orders.

Solving Brexit with Orange Connex
“Brexit was the catalyst. We could no longer sell supplements in the EU from the UK due to health authority regulations requiring an EU-based business entity.” Brexit forced Best Immune International to rethink its logistics strategy. EU health regulations required the company to establish an European entity in order to continue selling supplements in EU markets. To maintain access to these markets, the company opened a branch in Poland. Rather than building a warehouse operation internally, the company chose to outsource fulfilment.
On Base.com’s recommendation, they partnered with Orange Connex. Today, the entire fulfilment process runs automatically. Orders flow directly from Base.com into Orange Connex, where they are picked, packed, and shipped without manual involvement. This allows the business to scale without needing to manage warehouse staff or logistics infrastructure.
“Outsourcing to Orange Connex has removed the logistic burden entirely. Instead of hiring warehouse staff to pack orders as we scale, the orders just flow automatically from Base to Orange Connex, where they are picked, packed, and shipped without us getting involved at all”.

The Results: Automation and Better Customer Experience
Automating operations and outsourcing fulfilment significantly improved efficiency. With Base.com managing shipping automation, Jerry regained valuable time previously spent on operational tasks. In addition, reliable fulfilment also improved the customer experience.
“This automation alone saves me about 10 hours every week, which allows me to focus on growing the business. In addition, we’ve seen around a 50% reduction in shipping-related customer queries. That’s been a huge improvement for us, saving a couple of hours every week and allowing us to focus on other priorities.”

Diversifying Beyond Amazon
As the business grew, the team also focused on reducing reliance on a single sales channel. “Amazon accounted for about 85% of our sales, which naturally carries a level of risk”. To diversify, the company expanded to additional marketplaces, including Temu. “Expanding to Temu was an important step for us to diversify and strengthen our sales channels”. Temu’s rapid growth across Europe made it a particularly attractive opportunity. Because Base.com already centralised operations, adding Temu as a new channel was straightforward.
“With Temu operating in over 17 European countries and generating such significant traffic, it presented a fantastic growth opportunity for us.”- Jerry Cohen, Founder at Best Immune International
Today, Best Immune International operates across a wide range of marketplaces including: Amazon Europe, Temu, eBay, OnBuy and many more. This diversification has allowed the company to reduce risk and scale its brand across Europe. With Base.com managing operations across all channels, the team can continue expanding without increasing operational complexity.
What’s Next for Best Immune International
With automation and fulfilment now fully optimised, the business is focused on growth. Several new products are scheduled for launch in 2026, including Vitamin D3 drops and Chlorophyll drops. With Base powering automation, Orange Connex managing fulfilment, and new channels like Temu driving growth, Best Immune International is well positioned for its next phase of expansion.
“Because the operational side is now rock solid, we have the capacity to focus on expanding the brand.
