As the average age of the population in developed countries increases, microcirculation disorders are becoming more and more prevalent. Microcirculation impairment appears to be linked to the genesis of many pathological processes, including those concerning microcirculation in the brain.

If brain microcirculation (i.e. the reticulated complex of capillaries where venous and arterial circulation meet) becomes impaired, it can have a significant impact on a person’s quality of life, affecting cognitive and physical functions. The function of cerebral blood circulation is to deliver oxygen and nutrients to the brain and tissues, and also to eliminate toxins and waste substances.

So how can brain microcirculation be improved? In this article we will try to give you a detailed overview of the causes underlying these problems and of the currently available solutions.

What is brain microcirculation?

Brain microcirculation comprises the network of the smallest blood vessels in the brain, which are responsible for the distribution of blood (and therefore of oxygen and nutrients) to all areas of the brain.
Moving away from the heart, the arteries (which carry oxygen-rich blood) decrease in size until they flow into capillaries, which mark the point of passage to the venous circulation, through which deoxygenated blood is brought back to the heart to restart the circulation cycle.

As much as 74% of the entire circulatory system in our body consists of capillaries, while arteries and veins represent only 11.5% and 14.5% respectively of this system. This makes it easy to understand why correct blood circulation in the brain is vital to keeping all brain functions intact and preventing long-term damage.

Factors affecting brain microcirculation

Several factors can compromise the health of brain microcirculation. One of these is oxidative stress (OS), a condition that can damage brain cells and lead to the development of various neurological pathologies.

Recently, several publications in Nature ReviewScience and Science Translational Medicine have highlighted the role of free radicals or reactive oxygen species (ROS) in the onset of certain pathological conditions. Oxidative stress has been associated with a wide variety of disorders, including ADHD, Parkinson’s disease (PD) and Alzheimer’s disease (AD).

It has to be said that body ageing is certainly one of the possible causes of these problems. However, there are other causes, which are not linked only to previously diagnosed conditions (e.g. diabetes, some types of thyroid dysfunction or chronic renal failure), but also to lifestyle factors such as:

  • lack of physical activity;
  • smoking;
  • excessive alcohol consumption;
  • the use of drugs;
  • mental health disorders, such as anxiety and stress;
  • bad eating habits, which can lead to low-grade systemic inflammation;
  • overweight and obesity;
  • hypertension;
  • high levels of “bad” cholesterol (LDL) and triglycerides.

Strategies to reactivate microcirculation

To restore brain microcirculation, it is essential to take a holistic approach that includes several elements.

  • Balanced diet: a diet high in antioxidants, omega-3 and essential nutrients supports the health of blood vessels.
  • Regular physical activity: motor exercise stimulates blood circulation throughout the body, including the brain area.
  • Stress reduction: stress management techniques, such as meditation and yoga, can relieve pressure on the brain’s microcirculation.

But, if needed, we can support our body with dietary supplementation: let’s see how, together.

Central Nervous System Supplements: Cogiton against Oxidative Stress

Taking specific supplements can significantly support the health of brain microcirculation.  Supplements for the central nervous system, in particular, are in great demand among consumers because they are formulated to protect brain cells, help restore effective circulation and reduce the risk of tissue distress.

The health of brain microcirculation also has a direct influence on memory and concentration. In this sense, overcoming deficiencies with supplements can help improve memory and optimise cognitive functions.

Among the various supplements, Cogiton by Cor.Con International stands out for its effectiveness in supporting the normal function of the nervous system thanks to vitamins B1B2B3B6B12 and C; it also contributes to the protection of cells from oxidative stress thanks to the synergic action of vitamins B2, E, C and of Selenium. The Ginkgo Biloba contained in it also helps protect cells from oxidative stress, improving memory and cognitive functions.


We have seen that maintaining healthy brain microcirculation is essential to prevent future complications, including serious ones. By adopting a healthy lifestyle, choosing specific supplements such as Cogiton and being aware of the most common risk factors, it is possible to ensure efficient brain blood circulation and support long-term cognitive functions.
