To protect yourself and reduce the risk of getting sick, the first step is to follow a balanced diet and a healthy lifestyle, but the positive effects of these good habits can be further enhanced by supplements based on specific active ingredients, capable of effectively supporting the body in this delicate phase.
Let’s find out immediately what the main ones are.
Vitamin C
Vitamin C is one of the best-known supplements for supporting the body’s natural defenses, particularly when the first seasonal symptoms begin to appear or you feel more fatigued. Its action, however, is effective above all as a “prompt response”, in fact it helps immune cells to react quickly to external agents and reduces the intensity and duration of disorders typical of the cold season.
In addition to strengthening defenses, vitamin C also has an important antioxidant effect: it protects cells from oxidative stress and free radicals, helping to keep the body healthier and skin toned. Natural sources such as Acerola (rich in vitamin C) also promote collagen synthesis, supporting the structure of the skin and tissues.
To obtain the best results, it is preferable to integrate vitamin C through natural and concentrated products, which guarantee good bioavailability and targeted support for the immune system.

Vitamin D3 and K2
For true long-term prevention, it is essential to focus on vitamin D, preferably in the D3 form. This nutrient not only supports the normal functioning of the immune system but is also essential for cellular metabolism and calcium homeostasis, a key aspect for bones and tissues.
However, not everyone still knows that to maximize the benefits of vitamin D3 it is advisable to take it together with vitamin K2. In fact, K2 plays a crucial role in the safety of supplementation: it guides calcium towards bones and teeth, avoiding accumulations in the tissues and reducing the risk of arterial calcifications; activates the matrix GLA protein (MGP), which is essential for preventing calcium deposits in vascular walls, and can help protect the heart and arteries, especially when calcium intake is significant.
As you may have understood, vitamin D3 and K2 work in synergy: the first supports the immune defenses and calcium metabolism, the second ensures that calcium is used correctly, protecting bones, tissues and the cardiovascular system. This combination therefore represents a safe and effective approach to strengthening the body in the cold season (and beyond).

Postbiotic lactobacilli
A particularly interesting natural ingredient for supporting the immune system is represented by postbiotic lactobacilli, in particular Lactococcus lactis subsp. lactis JCM5805. It is a heat-inactivated lactic acid bacteria that, once consumed, is able to stimulate plasmacytoid dendritic cells (pDC), a special type of cells that support both the innate and adaptive immune systems.
Clinical studies confirmed the effectiveness of JCM5805: in participants who took this postbiotic lactobacillus daily, the days with symptoms such as sore throat and cough were significantly reduced compared to the placebo group. Furthermore, an increase in interferon levels was observed, demonstrating the enhancement of the antiviral immune response.
Other studies have also shown a reduction in the incidence and intensity of flu-like symptoms during the winter season, confirming the role of postbiotics in supporting immune defenses.

In addition to the individual nutrients already mentioned, there are many other natural active ingredients that can support the immune defenses and which, if taken in combination with each other, can give even more effective results. Let’s think for example of Shiitake (mushroom rich in beta-glucans with immunomodulatory properties), a plant like Uncaria, Propolis but also Zinc and Selenium, which act in synergy to strengthen the immune system, modulate the response to infections and support the body’s protection during the colder months.
The best supplements for immune defenses
Salugea – ImmunoGea
Food supplement: read the warnings on the label.
Supplements are not intended as substitutes for a varied, balanced diet and a healthy lifestyle.
Among the quality supplements to support the immune system in autumn (but also in the rest of the year), we highlight ImmunoGea from the Salugea brand, with a targeted and natural synergy for adults aged 13 and over.
Its formula is completely natural, free of gluten, colourants, preservatives and synthetic sweeteners, and uses innovative ingredients, such as Shiitake and the postbiotic lactobacilli mentioned above.
Alongside these active ingredients, ImmunoGea contains Uncaria, useful for supporting the body’s natural defenses, dewaxed Propolis (highly bioavailable form), and essential minerals such as Zinc and Selenium, which contribute to the correct functioning of the immune system. All ingredients come from natural sources and have high bioavailability, for optimal assimilation.
What makes this supplement truly special is not only the formula, but also the care taken in the packaging (and let’s not talk about aesthetics). The active ingredients are protected in pharmaceutical grade dark glass bottles, resistant and capable of preserving the quality of the product over time, even after the first opening.
Naturalsprint – Vitamin C + Echinacea + Zinc (High Dosage)
The Naturalsprint Vitamin C + Echinacea + Zinc supplement is a complete supplement designed to offer powerful immune support thanks to the synergy between vitamin C, echinacea and zinc.
Vitamin C constantly strengthens natural defenses and fights free radicals, while echinacea specifically stimulates the activity of immune cells, creating double protection especially in times of stress, cold or exposure to viruses.
This combination helps reduce the risk of getting sick and shorten the duration and intensity of colds and respiratory infections, promoting a faster and more natural recovery.
Thanks to its antioxidant and anti-inflammatory action, it offers a targeted defense against external attacks and protects cells and tissues from oxidative stress.
Supplements do not replace a balanced diet; it is recommended to consult your doctor in case of prolonged use.
Qualiterbe – QualiVit D3 + K2
An excellent vitamin combination is represented by the QualiVit D3 + K2 supplement from Qualiterbe, ideal for supporting the body’s natural defenses and maintaining bone and muscle systems in perfect health.
Vitamin D3, obtained from Cladonia rangiferina (a lichen capable of converting pro-vitamin D), contributes to the metabolism of calcium and phosphorus, promoting bone mineralization and the absorption of vitamin A.
Vitamin K2, on the other hand, optimizes the use of calcium, preventing it from accumulating in the soft tissues and at the same time improving coagulation mechanisms.
This synergistic combination represents a precious ally for general well-being, especially in the winter months or in cases of reduced sun exposure.
The product is Vegan OK, free of preservatives and colorants.
As you will have understood by now, if you want to support your immune defenses from the beginning of autumn until spring, you spend a lot of time in closed or crowded places, you are sensitive to sudden changes in temperature or you are over 65, some carefully selected natural supplements can really make the difference, helping you face the cold season with more energy and well-being.
