At Bradley’s Fish, we’re passionate about providing high-quality, nutrient-rich seafood you can trust. We also understand that for some people, managing histamine levels can make food choices more complex — particularly when it comes to fish.

Over the last few years, many of our customers have contacted us regarding Histamine Intolerance, directing us to helpful websites, Facebook groups, discussion forums and podcasts covering a wide range of topics — not just fish. These conversations have helped us better understand what matters most to those managing their diet carefully, and the challenges of Histamine Intolerance.

As a result, we have worked hard to source a wider variety of fish that are frozen at sea within 3 hours of being caught. This rapid freezing process locks in freshness quickly and helps to minimise histamine build-up. It also gives customers greater choice from a range of fish that provide essential vitamins and minerals for a healthier, balanced diet. Salmon also contains beneficial Omega-3 fish oils.  And we also understand that freezing speed makes a difference.

Because fish is naturally nutritious but must be handled correctly to maintain quality, the way it is caught, stored and frozen plays an important role. That’s why we focus so strongly on sourcing fish that is frozen at sea as quickly as possible — giving you confidence in both freshness and quality.

This guide explains what histamine intolerance is, why freezing methods matter, and how our carefully sourced range can help you shop with confidence.

What Is Histamine Intolerance?

Histamine is a natural compound involved in immune function, digestion and other important processes in the body. It is present in certain foods and is also produced naturally within us.

Histamine intolerance occurs when the body struggles to break down excess histamine effectively, often due to reduced activity of enzymes such as DAO (diamine oxidase). When histamine builds up, it may contribute to symptoms such as:

  • Headaches
  • Brain fog
  • Skin flushing
  • Digestive discomfort
  • Sleep disturbance
  • Irritability

Symptoms and tolerance levels vary significantly from person to person. Research into histamine intolerance is ongoing, and many individuals explore dietary management to help support their overall wellbeing.

Why Fish Handling Matters

Fish is one of the most nutrient-dense foods available — but it is also a food where histamine levels can increase if not handled correctly.

Histamine can develop when fish is stored in a chilled “fresh” state for extended periods. The longer the delay between catch and freezing, the greater the opportunity for histamine levels to rise.

For those who are sensitive, freezing speed is especially important.
