Quelques mots de nos clientes
« J’ai commencé Immu’boost en septembre sur conseil d’une amie, et je suis agréablement surprise. Avec mes deux enfants à l’école, d’habitude je tombe malade tous les mois… Là, rien ! Pas un seul rhume cet hiver. Je ne sais pas si c’est l’effet placebo, mais je continue ma cure ! »

« Je suis en pleine ménopause et j’étais tout le temps épuisée. J’ai testé Immu’boost pendant 2 mois et je vois clairement la différence : je tiens mieux le rythme, moins de coups de mou l’après-midi. Pas malade l’hiver, une première pour moi !
Je repars sur une cure. »

« L’hiver dernier, c’était l’angoisse : travail prenant, enfants malades les uns après les autres… J’étais épuisée. Et récemment, une amie m’a parlé d’Immu’Boost. J’ai hésité et j’ai sauté le pas fin octobre. Honnêtement, je n’ai pas vu venir les virus de la saison ! Même quand mon petit dernier a ramené une grosse grippe à la maison, j’ai juste eu un léger mal de gorge alors que d’habitude, c’est moi la première clouée au lit. Je continue toujours la prise. Pour moi, c’est devenu indispensable. »

« Sur les conseils de ma naturopathe, j’ai tenté Immu’Boost. Dès les premières semaines, j’ai senti un vrai regain d’énergie, et ma fatigue habituelle a complètement disparu ! Même quand la grippe a frappé autour de moi, mes symptômes sont restés très légers. Franchement, ce duo vitamine C et Thym m’a vraiment surprise par son efficacité. »

Your questions about Immu’Boost: we answer them.
Allergies, dosage, delivery, safety…
Everything you need to know before starting your treatment.
Who is Nuellia?
Nuellia is a French brand of natural food supplements designed for active, stressed and overwhelmed women. Our mission ? To help you regain your energy, boost your immunity and take care of yourself, naturally. We prioritise total transparency: traceable ingredients, effective dosages, formulas without unnecessary additives.
Why take a supplement?
A dietary supplement fills nutritional gaps or supports your body during stressful periods (stress, fatigue, hormonal changes, winter, etc.). Even with a balanced diet, certain nutrients may be lacking: vitamin D (lack of sunlight), magnesium (stress), iron (menstruation), etc. Supplements are a natural boost to help you feel better every day.
Are dietary supplements safe ?
Yes, when they are well-formulated and taken at the recommended doses. At Nuellia, we use natural, safe, and scientifically validated ingredients. However, if you are pregnant, breastfeeding, on medication, or have allergies, we recommend consulting a healthcare professional before starting a treatment.
Immu’boost contient-il des allergènes ?
Immu’Boost is gluten-free, lactose-free, and soy-free. However, if you are allergic to plants in the Asteraceae family (such as echinacea), consult your doctor before starting. The full composition is listed on the packaging and our website for complete transparency.
Are there any side effects ?
Immu’Boost is formulated with natural, well-tolerated ingredients. At the recommended dosages, there are generally no side effects. If you experience any, please consult a healthcare professional.
How long does a course of treatment last ? When will I see results ?
A full treatment lasts at least 2 months for optimal results. The first effects (more energy, less fatigue) can be felt as early as 2 to 3 weeks, depending on each person’s immune system. For lasting benefits to your immunity, we recommend a 2- to 3-month course.
Is Immu'boost suitable for children ?
Immu’Boost is formulated for adults. For children under 12, we advise consulting a pediatrician before any supplementation. For adolescents (12-18 years old), a half-dose (1 capsule per day) may be considered, always under medical advice.
Can I take Immu'boost if I am pregnant ?
As a precaution, we recommend consulting your doctor or midwife before taking any dietary supplement during pregnancy or breastfeeding. Although the ingredients are natural, some, like echinacea, are not always recommended during these periods.
Can I take Immu'boost with other supplements or medicines ?
Immu’Boost is generally compatible with other supplements. However, if you are taking prescription medications (especially anticoagulants, immunosuppressants, or thyroid treatments), consult your doctor before starting. Avoid combining it with other supplements that already contain high doses of vitamin C, zinc, or vitamin D.
Is Immu'boost suitable for vegetarians and vegans ?
Immu’Boost is 100% vegetarian. The capsules are plant-based (HPMC), and all ingredients are of plant or mineral origin. It is therefore perfectly suitable for vegans and vegetarians.
