Shellfish Allergy Natural Remedies

Eliminating shellfish from your diet is the first step to managing a shellfish allergy. There are several other supplements you can use as shellfish food allergy natural remedies to help strengthen your immune system and lessen the severity of adverse autoimmune reactions.

Probiotics help fill the gut with helpful bacteria that protect against allergies and other illnesses. For shellfish allergy treatment at home, take probiotic supplements or add probiotic foods to your diet, such as kombucha, sauerkraut, kimchi and kefir.
