We are led by Dr. Steve Collins MBE, MD Medical Doctor and pioneer in the field of nutritional science.

We have spent years investigating the positive effects of natural polyphenols and now share the science of their benefits with you. Discover how increasing your intake of these natural defenders can have a transformative impact on your health.

What Are Polyphenols?

Polyphenols are natural immune compounds found in plants. These 'natural defenders' form the immune system of plants and when you consume polyphenols, you benefit from their immune boosting properties.

We have long been told that increasing our fruit and vegetable intake is good for us, because they provide vitamins, minerals and fibre. However, a rapidly increasing body of scientific research is demonstrating that the polyphenols that they contain, are as important in promoting your health and longevity.   

Even with today’s highly processed diet, many of the common foods we eat are fortified with minerals and vitamins.  However, this is not the case with polyphenols and fibre. Studies show that most people are not consuming a sufficient amount to optimise their health.  

Aronia berries contain the highest level of polyphenols of any fruit or vegetable.

Top of the Charts

Aronia berries have the highest polyphenol content of any fruit or vegetable and because of this, they are one of the best researched fruits. Aronia berries have been scientifically shown to provide a wide range of different polyphenols and these have a variety of important health benefits.

Fresh aronia berries are best, but because of their extremely high polyphenol content, they can taste sharp and bitter, so are therefore rarely sold in shops as berries.

We use high quality and sophisticated production processes to ensure we minimisie any polyphenol loss to the berries to bring you aronia in enjoyable juices and powders.

Metabolically Speaking.

Your metabolism is the foundation of your health, encompassing the trillions of chemical reactions occurring in every cell of your body every day. 

For optimal health, these reactions must work efficiently and in harmony. This requires a consistent supply of a wide range of nutrients, in the correct amounts and chemical forms. 

Recent research has shown that polyphenols are extremely important nutrients, playing a fundamental role in promoting and supporting a variety of metabolic processes. Good metabolic health allows you to feel your best; decreasing bloating, cravings and stiffness; increasing energy, suppleness and your vitality.

What Is Blood Glucose?

Blood glucose is the main energy source used by cells in your body. It is the fuel that powers movement, growth and various chemical reactions in body cells. The brain is particularly dependent on blood glucose as its' energy source. Blood glucose is derived from all carbohydrates during digestion. It is absorbed from the intestine into the blood and from there, passing through the liver, is transported to all the cells of the body. Blood glucose is primarily stored in the liver and muscle cells.

Polyphenols Help to Reduce and Stabilise Blood Glucose

How Do Polyphenols Reduce and Stabilise Blood Glucose?

Polyphenols slow the breakdown of complex carbohydrates and the absorption of glucose from the intestine into the blood and increase the uptake of blood glucose into muscle cells. They do this in part through increasing the levels of gut hormones (incretins) such as GLP-1 that are produced by the intestine in response to food intake, providing a natural alternative to expensive drugs such as Ozempic, that have similar effects. Incretins have multiple beneficial effects throughout the body, reducing appetite and regulating food intake, increasing insulin secretion and insulin receptor sensitivity.

What Are Pathogenic Bacteria & Viruses?

Pathogenic bacteria damage the body by directly killing cells and producing toxins.

Pathogenic viruses invade the body's cells altering their activity and forcing the infected cells to produce more pathogenic virus.

Polyphenols Help to Combat Pathogenic Bacteria & Viruses

How Do Polyphenols Combat Pathogenic Bacteria & Viruses?

Polyphenols inhibit bacterial growth and reduce bacterial virulence by blocking their ability to adhere to and invade the body’s cells. They also support beneficial gut bacteria, which help combat harmful bacteria contained in food. Polyphenols can also deactivate certain viruses, prevent others from entering cells, or inhibit viral replication inside cells. Together, these actions enhance the immune system’s ability to fight infections.

What Are Blood Fats?

Blood fats, also known as lipids, are essential substances in your circulation that are crucial for your body’s functions. Maintaining their correct balance is important to reduce the risk of heart attacks and strokes and stay healthy. Some important types of blood fats are High-Density Lipoprotein (HDL) so called “Good Cholesterol” that helps keep your arteries healthy and Low-Density Lipoprotein (LDL) so called “Bad Cholesterol ” that transport fats from the liver to the organs and can build up in your arteries, forming plaques and causing them to block.

Polyphenols Help to Improve Blood Fats

How Do Polyphenols Improve Blood Fats?

Polyphenols lower the number of 'bad' cholesterol particles (LDL) and raise the number of 'good' cholesterol particles (HDL), improving the delivery of essential fats to the tissues, the return of unused fats to the liver, and reducing the risks that these stick to the artery walls, preventing cardiovascular disease.

What Are Antioxidant Defences?

Free radicals are molecules or atoms with unpaired electrons making them hyper-reactive. They protect the body against damaging levels of free radicals. Free radicals are hyper-reactive molecules that are present in the general environment and also are formed as a normal part of metabolism. They are necessary aspects of life and have multiple functions in the body. However when present in excess either through the environment (eg sun burn) or strenuous physical exercise or illness, they are damaging to your body.

Polyphenols Help to Strengthen Antioxidant Defences

How Do Polyphenols Strengthen Antioxidant Defences?

Polyphenols donate electrons to free radicals, rendering them non toxic, in a similar way to usual antioxidants. In addition and crucially, they switch on the production of the body's own antioxidant defences, such as glutathione. This profound action called an hormesis, produces positive adaptations in the body providing long term protection and metabolic improvements. This helps the body maintain a healthy balance of free radicals and protects vital tissues such as the blood vessels and insulin producing cells in the pancreas against damage.

What Is The Gut Microbiome?

The gut microbiome is the name for the trillions of micro organisms, mainly bacteria, that live in the gut, primarily in the large intestine. These microbes have a profound influence affecting the function of the whole body and the mind. The importance of the microbiome cannot be overstated and it is not possible to be healthy unless the microbiome is healthy.

Polyphenols Help to Strengthen Your Gut Microbiome

How Do Polyphenols Strengthen The Gut Microbiome?

Polyphenols support beneficial microbes in the gut microbiome, whilst suppressing harmful ones, thereby improving microbiome composition. They encourage bacteria that protect the gut lining, reduce toxin entry into the body, combat pathogens and communicate with the nervous system to enhance mood. Additionally, bacteria metabolising polyphenols produce short chain fatty acids, which protect cells, reduce inflammation and improve metabolism throughout the body.

What Is Chronic Inflammation?

Chronic inflammation is an uncontrolled inflammatory response, that progressively increases as you age and occurs in autoimmune diseases. It disrupts the body’s natural healing processes and over time damages tissues and organs. It is a driving force behind the progression of many serious conditions, such as cardiovascular disease, diabetes, and dementia. This is different to acute inflammation which is a controlled part of your immune response when you are sick or to heal a wound or injury and it goes away once the problem is fixed.

Polyphenols Help to Control Chronic Inflammation

How Do Polyphenols Control Chronic Inflammation?

Polyphenols reduce the chemical signals that switch on inflammation and increase the signals that switch off inflammation. Polyphenols have been shown to decrease pro-inflammatory cytokines such as IL-6 and TNF and increase anti-inflammatory cytokines such as IL-10. This regulates the beneficial acute inflammation response helping prevent it persisting, once the initial injury has passed.
