Unlocking Health and Performance: Dr Ishtiaq Rehman on the Science of Test-Based Nutrition and Omega Balance

The Vision Behind Test-Based Nutrition

Dr Ishtiaq Rehman, a highly respected consultant doctor with extensive experience in elite sport, including his work with the England FA and Sunderland FC, is on a mission to revolutionise health and performance through test-based nutrition. His expertise spans both medical and sports performance sectors, making him a pivotal figure in the development of Omega Balance protocols for athletes and the general population alike.

His philosophy is simple yet powerful: 


“We test beforehand to show you where the deficiencies are, and then we test afterwards to prove the objective difference with real data.”

[Dr Ishtiaq Rehman] 


Dr Ishtiaq Rehman’s approach is built on the foundation of personalised nutrition, using science-backed methods to ensure individuals optimise their health and performance by achieving an ideal omega-3 to omega-6 ratio. His work demonstrates how essential omega balance is for overall health, mental clarity, and athletic performance.

Why Omega Balance Matters for Everyone

As a medical professional, Dr. Ishtiaq Rehman emphasises the importance of achieving the correct balance between omega-3 and omega-6 fatty acids. In today’s society, many people—both athletes and non-athletes—are unknowingly living with imbalanced omega levels, leading to a range of health issues. 


“There’s a lot of misinformation out there about omega balance. When you consider long-term health, an imbalanced omega ratio can contribute to chronic inflammation, immune system dysfunction, and even mental health challenges.”

[Dr Ishtiaq Rehman]


Dr. Ishtiaq Rehman’s work is underpinned by scientific research showing that omega-3 fatty acids (EPA and DHA) help reduce inflammation, support brain health, and improve cardiovascular function. A balanced omega profile (ideally 3:1 omega-6 to omega-3 ratio) is critical in preventing many chronic conditions.

The Science Behind Omega Balance:

  1. Inflammation Reduction: Omega-3 fatty acids, especially EPA, lower inflammation in the body, a crucial factor for athletes undergoing intense physical activity.
  2. Mental Health: Research shows that omega-3s help regulate neurotransmitters in the brain, improving mood and reducing anxiety.
  3. Cardiovascular Support: Omega-3s improve heart function and reduce the risk of cardiovascular diseases by helping regulate blood pressure and cholesterol.

Dr. Ishtiaq Rehman shared the story of a professional bodybuilder client. Initially, the client’s omega-6 to omega-3 ratio was a worrying 14:1. After three months on Zinzino’s Omega Balance programme, his ratio improved to 4:1, proving the effectiveness of targeted omega supplementation.


"The results were remarkable. His recovery times improved, his energy levels increased, and he reported feeling mentally clearer and less anxious."

Omega Balance and Performance in Sport

Dr. Ishtiaq Rehman has witnessed first-hand how omega balance significantly impacts athletic performance at the highest levels. Working with elite athletes, including footballers and bodybuilders, he’s observed significant improvements in recovery, immune function, and mental resilience. 


“Athletes often suffer from chronic inflammation without realising it. By addressing this imbalance, we can improve recovery times, reduce injuries, and enhance overall performance.”

[Dr Ishtiaq Rehman]


A balanced omega profile not only supports physical performance but also improves mental clarity, focus, and emotional well-being—essential for excelling in competitive sports.

Key Benefits of Omega Balance for Athletes:

  1. Enhanced Recovery: Omega-3s reduce post-exercise inflammation, speeding up recovery and decreasing muscle soreness.
  2. Boosted Immune Function: Correcting omega balance strengthens the immune system, reducing the likelihood of illness during intense training periods.
  3. Improved Cognitive Performance: Omega-3s improve brain function, aiding focus, reaction time, and decision-making under pressure.

Test-Based Nutrition: A New Standard in Healthcare

One of the core principles of Dr. Ishtiaq Rehman’s work is test-based nutrition. Unlike generic approaches, where advice is broadly applied, test-based nutrition is highly individualised. By using blood tests, Dr. Ishtiaq Rehman and his team at Test-Based Nutrition create a detailed health profile that highlights specific deficiencies and imbalances.


“We don’t guess; we test. This allows us to deliver precision nutrition. Whether you’re an elite athlete or someone looking to improve their general health, this approach ensures your body gets exactly what it needs.”

[Dr Ishtiaq Rehman]


The Zinzino Omega Balance Test, used by Dr. Ishtiaq Rehman, measures essential health markers such as the omega-6 to omega-3 ratio, EPA/DHA levels, and cellular membrane fluidity. The data is then used to tailor a nutritional plan that addresses the individual’s specific health needs.

The Test-Based Nutrition Process:

  1. Initial Testing: A comprehensive blood test provides insights into omega levels, cardiovascular health, and overall cellular health.
  2. Targeted Intervention: Based on test results, individuals receive personalised nutritional recommendations, including Omega Balance Oil supplementation.
  3. Retesting for Results: After three months, clients are retested to measure improvements, ensuring the interventions have made a measurable impact.

Omega Balance for Long-Term Health

Dr. Ishtiaq Rehman stresses that omega balance isn’t just vital for athletes; it’s crucial for anyone aiming for long-term health. Omega-3 deficiency has been linked to a variety of chronic health problems, including cardiovascular diseases and mental health disorders. By correcting this imbalance, individuals can protect themselves from these long-term risks. 


"Too often, healthcare systems only address problems when it’s too late. By measuring and correcting deficiencies early on, we can prevent many of the health issues people face later in life."

[Dr Ishtiaq Rehman]


Research supports Dr. Ishtiaq Rehman’s claims. Studies from respected sources, including PubMed and Google Scholar, confirm the role of omega-3s in reducing the risk of chronic conditions such as heart disease, arthritis, and depression. Omega-3s also improve cognitive function and mental well-being, making them a critical component of overall health.

A Healthier Future Through Science

Dr. Ishtiaq Rehman’s mission is clear: to bring science-based nutrition to the forefront of healthcare. Through test-based nutrition, he aims to help individuals—athletes and non-athletes alike—achieve optimal health by addressing their specific nutritional needs.


"Our vision is to make test-based nutrition accessible to everyone. By using proven science, we can help people achieve better health, better performance, and a better quality of life."

[Dr Ishtiaq Rehman]


With the support of robust scientific research and measurable results, Dr. Ishtiaq Rehman and his team are leading the way in a future where nutrition is personalised, precise, and preventative.
