Welzo UK Health Index 2025: The Nation’s Most Common Vitamin Deficiencies Revealed

The latest findings from Welzo’s UK Health Index 2025 reveal a worrying trend: millions of people across the United Kingdom are living with hidden vitamin deficiencies that could be silently affecting their health. Welzo is a UK based healthcare marketplace that sells supplements, vitamins, and health tests, founded in 2022. With a focus on accessibility and innovation, Welzo (welzo.com) is using its advanced data analysis tools to map the nation’s nutritional health more accurately than ever before.

The British entrepreneur and CEO of Welzo, Adonis Hakkim, explains that the future of wellness is becoming deeply personalized through real, objective data derived from biomarkers. By leveraging Welzo’s AI-driven system alongside home health testing, individuals can uncover meaningful insights about their bodies, empowering them to take smarter, preventative steps toward better health.

A Comprehensive Look at the UK’s Nutritional Health

The Welzo UK Health Index is a compilation of anonymized health data of thousands of at-home tests uploaded by the service. Every year, the company summarises and interprets this data to determine the way the nutritional habits of the population are evolving.

The Index that was released in 2025 indicates that people have become more aware of supplements, but the majority of Britons are still not getting their daily nutrient intake. The most frequently deficient vitamins include D, B12, and folate, which are predominantly involved in the urban regions where there is a lack of sunlight and dietary variety.

The Vitamins the UK Is Most Deficient In

The report mentions some of the key deficiencies of the nation.

• Vitamin D deficiency can be especially pronounced in autumn and winter months. The main reason is a lack of sunshine.
• Vitamin B12 deficiency is especially common among vegetarians and vegans due to the diminished intake of animal-sourced foods.
• Iron deficiency particularly concerns women in the productive age.
• Magnesium: stress, non-diet, and alcohol typically waste it.
• Omega-3 fatty acids are insufficient in most diets because of low fish intake.

These results characterize an increasing disparity between consciousness and behavior. They understand the importance of supplements, and many just fail to take them regularly, as they are supposed to.

What Makes the Welzo Health Index Unique

The Welzo Index is based on real-life biological information as opposed to survey data, which are used in the traditional health reports. The data provided directly by the users’ home blood tests is a genuine account of how the health of the population will change in a given time period.

Based on the latest analytics, Welzo will be able to apply segmentation based on region, age, and lifestyle to identify the areas that lack the most. This data assists people and aids the medical fraternity in comprehending the macro health trends.

Bringing Awareness Through Data and Education

Nor is the publication of the UK Health Index merely to point out the ills; it is also meant to make one take positive measures in managing their health. Welzo will provide each individual with a chance to know their nutritional situation, make well-informed choices, and prevent the onset of chronic diseases.

To provide this mission, Welzo collaborates with scientifically verified supplement brands such as Momentous. Momentous provides high-quality formulations that meet the performance, recovery, and overall daily vitality of the users, which are known as inadequate by Welzo testing.

Commenting on the project, Adonis Hakkim stated, “Data is the future of health. The Welzo Health Index is not just a report, it’s a roadmap for improving the nation’s well-being. Every data point represents a life that can be enhanced through awareness and action.”

He added that this philosophy reflects Welzo’s preventive and proactive approach, empowering individuals with the tools to take charge of their health before symptoms even appear.

Why These Deficiencies Matter

Though the deficiency of vitamins may appear insignificant, it may cause stress on health in the long run, unless addressed. Deficiency of vitamin D impacts the immunity and bone density; the lack of B12 may lead to tiredness and memory issues. In its turn, iron deficiency is one of the causes of anemia and lack of concentration. And by doing so at a young age, one can dramatically enhance energy and mood, in addition to well-being: this is what thousands are experiencing every day thanks to Welzo technology.

The Future of UK Health Tracking

The Welzo UK Health Index 2025 is not the end. As the research continues, the company will expand its data and incorporate an additional number of biomarkers regarding nutrition, stress, and sleep. Onward evolution will draw an even more definite image of public health in the future. Adonis Hakkim is convinced that the trend of introducing real-time health data to daily life will become the new reality. He imagines a world where humans will never take guesses regarding their health; they will know what their body requires at all times.

According to the findings of Welzo’s UK Health Index 2025, vitamin deficiencies represent a silent epidemic across Britain. By combining accessible at-home testing, advanced analytics, and partnerships with trusted supplement brands, Welzo is pioneering a new era of personalized, data-driven health management.
