Post-stroke fatigue is a debilitating condition affecting a large proportion of patients following an ischemic event. This article explores the causes, impact on quality of life, and potential nutritional strategies, with a focus on Sucrosomial® Technology and the results of a clinical study conducted with SiderAL® Med.

What is Post-Stroke Fatigue?

Physical and mental exhaustion, known medically as fatigue, is characterized by energy loss, weakness, irritability, and anxiety. Its causes are multiple, including:

• Periods of stress
• Irregular lifestyle
• Unbalanced diets
• Seasonal changes
• Aging
• Disturbed sleep
• Intense physical activity

Among these, post-stroke fatigue (PSF) is a frequent and frustrating outcome for stroke survivors. It can persist for years, interfering with daily activities and overall quality of life. Clinically, PSF is hard to define due to its subjective nature, but it typically involves intense tiredness, early exhaustion, and difficulty performing even simple tasks.1,2

Incidence and Impact of Post-Stroke Fatigue

Post-stroke fatigue affects over 40% of patients in the early stages following the event and significantly impacts the rehabilitation process. It reduces both motor and cognitive recovery capacity, making it harder for patients to regain independence.3

The Role of Nutrition and Micronutrients

A healthy and balanced diet is essential for general well-being and sustained energy levels. To combat fatigue and boost energy through diet, it is important to consume foods that offer essential nutrients and a steady energy release. While macronutrients (carbohydrates, proteins, fats) provide energy, micronutrients—vitamins and minerals—ensure the proper functioning of cellular metabolism.

Vitamins are a heterogeneous group of organic compounds classified based on their solubility: water-soluble (e.g., vitamin B12, C) and fat-soluble (e.g., vitamin D, E). They are absorbed throughout the small intestine, some in the duodenum (e.g., vitamin D), others in the ileum (e.g., vitamin B12).
Minerals are essential inorganic compounds that must be obtained from the diet, as the body cannot synthesize them. Once ingested, they are not metabolized by any enzyme and are primarily absorbed in the duodenum, the first segment of the small intestine.

Vitamins and minerals are vital for cellular energy production, muscle function, and brain health.4 A deficiency in these micronutrients can lead to lethargy and both physical and mental fatigue.5,6 Specifically:

  • Iron deficiency, even without anemia, impairs muscular function.
  • Magnesium deficiency increases oxygen demand and reduces physical endurance.

Supplementation and Sucrosomial® Technology

Supplementing vitamins (A, B1, B2, B6, B12, C, D, E, K) and minerals such as iron and magnesium can improve both physical and cognitive performance. However, the bioavailability of these elements is often limited.
To overcome this barrier, PharmaNutra developed the Sucrosomial® Technology: a delivery system that encloses minerals in a matrix of phospholipids and sucrose esters of fatty acids. This structure, called Sucrosome®, protects the nutrients from the gastric environment and facilitates intestinal absorption, enhancing both tolerance and efficacy.
This delivery system prevents mineral release in the stomach, improving absorption and avoiding the side effects commonly associated with conventional supplements.7,8

SiderAL® Med and Post-Stroke Fatigue: The Clinical Study

SiderAL® Med is a food for special medical purposes containing a comprehensive blend of vitamins, Sucrosomial® minerals (iron, iodine, magnesium, zinc, selenium), copper, and algae-based calcium.
A recent clinical trial (“The role of nutritional supplement on post-stroke fatigue”) led by Dr. Giovannini’s team at the Catholic University of the Sacred Heart in Rome evaluated the efficacy of SiderAL® Med in patients experiencing post-stroke fatigue.

The observational study included 24 patients with post-stroke symptoms, aiming to assess the supplement’s impact on physical and mental fatigue, motor and cognitive activity, quality of life, and bone mineralization. Participants were divided into two groups: one received one sachet of SiderAL® Med daily for 8 weeks, in addition to rehabilitation therapy; the other group followed standard therapy alone.

Results showed a statistically significant improvement in post-stroke fatigue among patients treated with SiderAL® Med, an effect sustained even two months after the study began. Additionally, a reduction in fat mass and increase in lean (muscle) mass was observed, with positive effects on mobility, strength, and overall quality of life.9

To conclude, nutritional supplementation, combined with rehabilitation therapy, proved to be an effective and well-tolerated strategy for managing post-stroke fatigue. The study’s findings suggest benefits for both physical and cognitive performance, contributing to an overall improvement in quality of life for stroke survivors.
