Revilan Immuno food supplement for immune defenses and seasonal infections
Seasonal changes, seasonal flu, recurrent respiratory infections and lowered immune defenses are very common conditions in both adults and children, especially during the coldest months of the year. Stress, tiredness, an unbalanced diet, convalescence periods and intense daily activity can all contribute to making the body more vulnerable to external agents.
Upper respiratory tract infections, flu syndromes and recurrent episodes of otitis or airway inflammation are common issues associated with an increased immune demand. In these cases, it can be useful to support the body with supplements formulated with vitamins, minerals and immunostimulant active ingredients.
Revilan Immuno is a food supplement based on B vitamins, vitamin C, vitamin D, zinc, lactoferrin, beta-glucans, resveratrol and Shiitake and Reishi extracts, developed to support the body’s natural defenses and contribute to the normal function of the immune system.
The product is intended as a support during seasonal changes, recurrent respiratory infections and seasonal flu.
Low immune defenses and seasonal infections
The immune system represents one of the body’s main defense barriers against viruses, bacteria and external agents. However, at certain times of the year, immune defenses can physiologically decrease.
Among the factors that can contribute to lowered defenses are:
- physical and mental stress
- prolonged tiredness
- seasonal changes
- an unbalanced diet
- insufficient sleep
- post-flu recovery periods
- intense work or school activity
When the body is more vulnerable, the following may occur:
- seasonal flu
- recurrent colds
- respiratory infections
- ear infections (otitis)
- sore throat
- frequent flu episodes
In these situations, it can be useful to support the immune system with specific nutrients and immunostimulant active ingredients.
Vitamins C, D and zinc: support for the immune system
Among the main nutrients found in Revilan Immuno are:
- vitamin C
- vitamin D
- zinc
- B vitamins
Vitamin C contributes to the normal function of the immune system and to the protection of cells from oxidative stress, while vitamin D plays an important role in regulating the immune response.
Zinc also contributes to normal immune function and to maintaining the body’s physiological defenses.
B vitamins, on the other hand, support energy metabolism and help counter tiredness and fatigue, conditions often associated with flu and stress periods.
Beta-glucans and lactoferrin: immunostimulant active ingredients
One of the distinctive elements of Revilan Immuno is the high concentration of beta-glucans derived from S. cerevisiae. The formulation contains 85% yeast beta-glucan with high titration.
Beta-glucans are polysaccharides studied for their role in supporting the body’s natural defenses and immune activation.
The formulation also contains lactoferrin, a glycoprotein naturally involved in the body’s defense mechanisms and frequently used in supplements dedicated to the immune system.
Revilan Immuno is developed to help activate macrophages and T lymphocytes, cells involved in the immune response.
Shiitake, Reishi and resveratrol: antioxidant and immune support
The formulation also includes:
- Shiitake extract
- Reishi extract
- resveratrol from Polygonum cuspidatum
Shiitake and Reishi extracts are rich in polysaccharides and are traditionally used to support the body’s natural defenses.
Resveratrol, on the other hand, is a polyphenolic compound known for its antioxidant activity and for supporting the body against cellular oxidative stress.
This combination helps make the formulation particularly complete during periods of greater immune stress.
Scientific evidence on beta-glucans, lactoferrin and the immune system
In recent years, scientific research has deepened the understanding of the role of beta-glucans, lactoferrin and immunomodulating micronutrients in supporting the body’s natural defenses, especially during respiratory infections and periods of greater immune stress.
A study published on PubMed evaluated the effect of yeast-derived beta-glucans on the immune system, highlighting the ability of these polysaccharides to modulate the activity of innate immune cells such as macrophages and neutrophils. The authors point out that beta-glucans may contribute to supporting the immune response and protecting the body during exposure to infections and physiological stress.
Lactoferrin has also been the subject of numerous studies for its involvement in immune defense mechanisms. A scientific publication on PubMed highlighted the role of lactoferrin in protecting the body thanks to its ability to bind iron and contribute to regulating the immune response and natural antimicrobial activity. According to the authors, lactoferrin may play an important role in supporting mucosal and physiological defenses against pathogens.
Further, more recent scientific evidence has also explored the combined role of micronutrients and immunomodulating active ingredients in the immune response and in protecting the body during respiratory infections and inflammatory states. A review published in 2024 confirmed the growing interest in ingredients such as vitamin D, zinc, beta-glucans and lactoferrin for supporting immune function and the physiological inflammatory response.
This evidence supports the use of formulations containing beta-glucans, lactoferrin, vitamins and immunostimulant ingredients as nutritional support during periods characterized by lowered immune defenses, seasonal infections and increased needs of the body.
