Runny nose, repeated sneezing, watery eyes, itchy throat and palate... Every year, the same story repeats itself... As soon as the beautiful spring days arrive, seasonal allergies , commonly known as "hay fever" , point the tip of their nose to make life hard for us!
It is in fact an allergic phenomenon , that is to say an excessive and inappropriate immune reaction against harmless substances (allergens), in this case the pollen of trees, shrubs and grasses.
Before you rush on antihistamines , corticosteroid medications and anti-inflammatories to relieve your symptoms, know that these treatments have many side effects ! Opt instead for natural remedies which, in addition to being often just as effective , are better tolerated by the body .
Istanat is a 100% natural food supplement rich in vitamin C , magnesium and quercetin , nutrients that act in synergy to regulate the functioning of the immune system and thus calm seasonal allergies .
Find out more about this natural remedy for hay fever and other seasonal allergies.
Istanat: presentation and composition
Istanat is a dietary supplement intended for the natural treatment of allergic rhinitis commonly known as "hay fever" (seasonal allergies to tree and grass pollen).
Unlike conventional medications, Istanat will not act on hay fever symptoms in isolation. Rather, it has a global action on the entire immune system .
Indeed, by providing the immune system with all the nutrients essential to its functioning and thanks to the immunomodulatory action of quercetin , this food supplement regulates immunity and reduces allergic reactions .
Each of the natural substances present in the composition of Istanat has a beneficial action on the immune defences:
Vitamin C , also called “ ascorbic acid ” , is a water-soluble vitamin that participates in hundreds of biochemical processes in the body. It is particularly involved in the production of collagen (protein present in the majority of body tissues), nerve transmission and immunity .
Thanks to its antioxidant properties , vitamin C protects our cells, especially those involved in immunity, from oxidative stress , i.e. the harmful effects of free radicals . It therefore contributes to the proper functioning of the immune system .
In addition, vitamin C has a natural antihistamine action , because it inhibits the secretion of histamine by certain immune cells.
As a reminder, histamine is one of the main biological substances responsible for the allergic symptoms of hay fever . Its blocking by vitamin C therefore allows a slight reduction in nasal discharge, tearing, tingling of the throat...
The daily dose of Istanat (2 tablets with each meal) provides the body with 180 mg of vitamin C , enough to largely cover our daily needs for this vitamin and contribute to the functioning of the immune system.
In addition, vitamin C is also very good for the skin ! Because, in addition to supporting the production of collagen, it helps to fight effectively against the premature aging of skin cells.
Magnesium is an essential trace element for our body , because it is involved in hundreds of important metabolic reactions. In particular, it contributes to the production of immunoglobulins , proteins that play a key role in immune reactions.
This trace element is also involved in fixing immune cells, which allows normal functioning of the immune system .
Also, magnesium in cure helps to limit allergies , especially hay fever .
Istanat provides 100 mg of magnesium citrate , a dose that covers a good part of our daily needs in a form that is easily assimilated and very well tolerated by the body.
In addition, magnesium is also indicated in the fight against stress and states of fatigue , the prevention of muscle cramps/aches , the improvement of the quality of sleep and the increase in sports performance .
Quercetin, also called "quercetol" , is an organic molecule naturally present in plants. It is in particular the latter which gives their color to certain vegetables, fruits and flowers since it is part of the large family of flavonoids (plant pigments).
Quercetin is a recognized natural antioxidant , it is able to fight against oxidative stress in the body and thus preserve the integrity and functioning of cells, especially immune cells.
In the context of a seasonal allergy such as hay fever , quercetin supplementation is particularly indicated thanks to its antiallergic effects:
- Reduction in the production/release of histamine and other pro-inflammatory substances involved in the onset of allergy symptoms (watery eyes, itchy throat, sneezing, etc.).
- Reduction in the formation of type E immunoglobulins (IgE) involved in the allergic reaction.
- Reduction in the formation of certain enzymes involved in the allergy process.
Quercetin is not essential for the functioning of the body, our diet is also very deficient in it. However, its powerful antioxidant properties and its regulatory action on the immune system justify its supplementation in many people, particularly those prone to seasonal allergies.
The food supplement Istanat provides a quantity of quercetin largely sufficient to limit excessive immune reactions , prevent seasonal allergies and effectively soothe their symptoms.
In addition, quercetin is also recognized for its cardioprotective, anti-inflammatory and anti-cancer properties .
Indeed, consuming daily foods rich in quercetin (blackcurrant, raw red onions, capers, lovage, etc.) or taking a food supplement such as Istanat would contribute to the prevention of certain cardiovascular diseases such as cerebrovascular accidents (CVA) and heart attacks. myocardium (heart attacks), fighting inflammation in the body and reducing the risk of cancer.
Blackcurrant is recognized for its "cortisone-like" anti-inflammatory action , that is to say, it mimics the effect of cortisone , a substance naturally produced by the body whose role, among other things, is to reduce the inflammation and regulate the immune response .
You should know that in certain forms of seasonal allergies resistant to conventional antihistamine treatment , doctors can prescribe corticosteroids (cortisone derivatives) intramuscularly or orally to effectively reduce allergic reactions .
Blackcurrant , by stimulating the adrenal glands so that they increase the level of cortisone in the blood, is therefore indicated in the treatment of hay fever or seasonal allergies.
Additionally, black currant extract is very high in vitamin C and quercetin , two nutrients known for their natural antioxidant and antihistamine properties .
Lemon has been used for centuries in the treatment of hay fever . Thanks to its richness in flavonoids, mainly the flavones hesperidin and eriocitrin , the lemon extract present in the composition of Istanat offers powerful antiallergic properties.
Lemon extract also provides a significant amount of natural vitamin C , the latter being known for its antioxidant and antihistamine properties effective against hay fever and all kinds of allergies .
red onion extract
For generations, raw red onion has been used in the natural treatment of hay fever. Its antiallergic properties , the red onion owes them to its richness in antioxidant and immune-regulating active ingredients such as vitamin B6 , vitamin C and quercetin .
While vitamin C and quercetin exert their powerful antioxidant and antihistamine actions, blackcurrant extract regulates the immune system thanks to its cortisone-like effect and lemon extract soothes allergic reactions thanks to its flavones (hesperidin and eriocitrin ). Without forgetting magnesium which supports immunity and facilitates its interventions.
In short, all the ingredients of the Istanat food supplement act in synergy to regulate the immune system and effectively fight against seasonal allergies !
