- Supports respiratory health and may help to improve breathing

- May be beneficial for those who suffer from sinus issues

- May be beneficial for those who suffer from seasonal allergies, such as hay fever

- Features Isoquercitrin, a clinically studied, more superior and bioavailable form of quercetin, a natural antihistamine

Aller C® contains vitamin C, alongside Isoquercetin, a clinically studied, bioavailable form of quercetin, found naturally in foods such as apples, and hesperidin, found naturally in citrus fruit. Together, these ingredients may act like natural antihistamines by helping to balance the activity of mast cells, which release histamine. Aller C® may therefore be suitable for anyone who suffers from the effects of excess histamine, which can trigger hay fever or allergic type symptoms. It may also help those suffering from histamine intolerance or diagnosed with Mast Cell Activation Syndrome. As well as supporting the immune system, vitamin C can also support respiratory and sinus health, and may help to improve breathing by reducing inflammation in the airways.
