MasWorth has announced that it has secured a new health claim olive oil certification, marking a major milestone for the company and setting a new benchmark in the growing category of functional fats. This certification confirms that selected MasWorth oils meet strict criteria for naturally occurring compounds that contribute to recognised health-supporting properties.

The new certification covers oils with high levels of polyphenols, antioxidants and beneficial monounsaturated fats, all of which are naturally found in early harvest extra virgin olive oil. MasWorth has long focused on sourcing olives from traditional farms where early picking and careful production methods help preserve these compounds without chemical interference or excessive processing.

This achievement strengthens the company’s position as a trusted supplier of premium olive oil in the UK. The certification also supports MasWorth’s commitment to transparency, authenticity and informed consumer choice. By meeting the recognised standards of a novel health claim, the company is helping set a clearer path for customers seeking oils with meaningful natural benefits.

A spokesperson for MasWorth shared their thoughts on the news, saying, “Securing this certification is a proud moment for us. It reflects the hard work that goes into every bottle and confirms that our focus on purity, early harvest olives and traditional cold pressing truly makes a difference. We want customers to know exactly what they are buying, and this certification helps make that possible.”

The certification process involves verifying the oil’s polyphenol content, examining its production methods and ensuring that the final product meets strict quality markers. For MasWorth, these requirements align closely with the practices already in place across its supply chain, which includes partnerships with small farms and mills that share the company’s values.

MasWorth believes that this recognition will help build greater understanding of what genuine extra virgin olive oil should be. Many oils on the market are refined or mislabelled, leaving consumers uncertain about what they are purchasing. With this certification, the company hopes to offer clarity and reinforce the importance of authenticity.

The company has always highlighted the natural strengths of early harvest oils, and this new achievement underscores that message. Early picked olives contain concentrated levels of polyphenols, helping the oil maintain its fresh, peppery flavour while supporting its natural stability and nutritional properties.

MasWorth plans to feature the certification across relevant product labels and digital materials to help customers identify qualifying oils easily. The company views this as an important step in promoting informed choices and elevating industry standards.

The announcement has already sparked interest among retailers and customers who value food products backed by credible testing. MasWorth expects the demand for certified oils to rise as consumers become more aware of the science linking natural olive compounds to improved wellbeing.

In addition to validating its current production, the certification supports MasWorth’s long-term vision of championing high-quality, minimally processed olive oils in the UK market. It also provides a platform for the company to continue expanding its offering with oils that meet the same recognised standards.

The company plans to use this milestone as an opportunity to educate the public on what health claims in olive oil truly mean. MasWorth intends to share simple explanations about polyphenols, antioxidants and early harvest techniques to help customers recognise quality and make confident choices.

Early reactions from loyal customers have been positive, with many expressing appreciation for the company’s transparency and commitment to raising the bar in an industry where quality can vary widely. MasWorth sees this certification as a step forward for both the brand and the wider market.

This achievement also highlights the value of long-term relationships with farmers who prioritise traditional methods over mass production. By supporting these growers, MasWorth continues to preserve agricultural heritage while ensuring that customers receive oils that stay true to their origins.

With this new health claim certification, MasWorth is setting a higher standard for what functional fats can and should be. The company looks forward to building on this success and continuing its mission of providing olive oils that combine authentic flavour, natural purity and scientifically recognised benefits.

MasWorth remains committed to offering customers products they can trust, and this certification serves as another example of the company’s ongoing dedication to quality and transparency in every bottle it brings to the market.
