Our Organic acerola is a natural and high quality source of vitamin C. Vitamin C is essential to almost all physiological functions of our body. Specifically, it helps maintain a high level of energy and build-up our immune defences.

Copper has a special mention when it comes to immunity - it is the fatal weapon that our own white blood cells (the commandos of our immune system) use to eliminate pathogens. Copper is extremely cytotoxic - even at low concentrations, its contact with bacteria is fatal to them. This is exactly what our white blood cells do when they cluster around a pathogen: they use their copper ion pumps to increase the concentration locally and kill the bacteria. Copper is therefore necessary for the normal functioning of the immune system, hence the importance of having an adequate supply.

This mineral has a long list of health benefits, but for the Winter edition, we are particularly interested in its contribution to the functioning of the immune system. It participates in the proper development of specialized cells such as neutrophils or natural killer cells (NK cells), which act as sentinels and are among the first actors called upon during an immune response to a pathogen. Some studies have even shown that Zinc supplementation can reduce the duration of a cooling episode or common cold.

This small berry from Brazil has become popular thanks to its presence in many energy drinks. Indeed, it contains an impressive amount of caffeine that reduces fatigue - but not only! Guarana contains a list of active compounds similar to green tea, and is therefore known for its ability to strengthen the immune system and act against mental fatigue.

Maca is a plant native to Peru that belongs to the same family as broccoli or cauliflower. It has a long history of use in local traditional medicine, and today its popularity is booming - it is particularly valued for its stimulating action on energy levels and mood in general... but also on libido in men and women and fertility in men! A little something extra for this winter!

Spirulina is nowadays commonly classified as a "Super-food" - and for good reason! This algae extract is rich in a wide range of micro-nutrients such as vitamins A, E, C, Zinc, Magnesium and Selenium. And as we have just seen, many of these elements are involved in the proper functioning and strengthening of the immune system, as well as energy metabolism. In other words, it is an ideal companion for our selection of winter supplements!

It is the bonus ingredient of our LyftoBox Winter Edition. We don't often hear about it, but this fungus, which is mainly grown in Japan, is rich in many vitamins (especially the B vitamin family) and minerals that play a role in the functioning of the immune system and the prevention of fatigue.

Selenium is also a major component in the activation of the immune system. Many studies and publications exist on its involvement in the activation, proliferation and maturation of different cells of our innate and acquired immune system. Selenoproteins (specialized proteins that incorporate selenium into their structure) use it as a catalyst to perform their specific functions, including those related to the development of the immune response.

Vitamin D3 is synthesized by our body through a process catalyzed by the sun's rays - obviously, its production is therefore problematic when the sun is not present! This is why winter is a privileged season for vitamin D3 supplementation. Apart from its crucial function in fixing Calcium in the bones, vitamin D3 also plays an important role in the normal functioning of the immune system. Ours is extracted from lichen, not sheep's wool, making it one of the only sources of vegan and vegetarian vitamin D3!

The root (or rhizome, more precisely) of this plant with many medicinal properties originates from the forests of the tropical region of India and Southeast Asia. Rich in manganese and potassium, ginger has been used for more than 5,000 years in traditional Chinese and Indian medicine as a natural energy stimulant and in the treatment of colds. In short, a great addition to our winter health arsenal!

Echinacea is a family of herbaceous plants that includes nine different species. Preparations based on this plant have long been used in traditional medicine to boost immunity and help treat colds. Today, we know that Echinacea works by increasing the number of white blood cells and other cells of the immune system and thus helps the body's natural defences to function properly.

This plant that we all know is a real boon for our immune system. It is particularly rich in very specific antioxidants called polyphenols. There are different forms of it, but for us, two are particularly interesting: EGCG and L-theanine. It has been shown that EGCG can bind to the influenza virus and prevent its infectious action, while L-theanine increases the number of certain cells in the immune system and boosts their action. Green tea extract thus strengthens the immune system and improves the body's defences.

Vitamin E is a powerful antioxidant that has many beneficial properties for our body. It helps protect the body from oxidative stress - that is, it protects our cells from damage caused by free radicals. But in winter, it is also appreciated for its contribution to the proper functioning of the immune system.
