Antihistamine Supplements For Hayfever Season

Spring is here, and with it, allergy season is also present for many of us. If you suffer from seasonal allergies, you understand how challenging the constant sneezing, sniffling, the itchy eyes and the blocked sinuses can be.

For many, over-the-counter antihistamine medications must be taken throughout spring and summer, but it’s also a good option to explore what natural supplements can assist with allergy symptoms when taken regularly.

We have compiled a list of supplements that have shown to relieve the symptoms of hayfever and seasonal allergies – so let’s get into it!

Vitamin C

Vitamin C acts as a natural antihistamine, as well as boosting the immune system. In a 2018 study, it was shown that in the treatment of allergies, oxidative stress plays a major role in allergic diseases, and as vitamin C is such a powerful antioxidant and anti-inflammatory, it can act as a treatment for allergies.

In the same study, it was shown that those who suffer from a vitamin C deficiency are more likely to experience allergy-related diseases.
