- Vitamin E supports a healthy pregnancy — Vitamin E intake during pregnancy has been shown to reduce the risk of food allergies in newborns by stabilizing immune responses and lowering histamine levels
- Vitamin E alters histamine production — Researchers found that α-tocopherol, a specific form of vitamin E, prevented severe allergic reactions by reducing the release of histamine, the chemical responsible for swelling, itching and anaphylaxis (a severe allergic reaction)
- Infants get the benefits of vitamin E immediately — Babies with genetic skin barrier weaknesses, such as those linked to eczema, are more likely to develop food allergies, but vitamin E helps reinforce immune regulation and reduce their risk
- Vitamin E doesn’t interfere with your body’s natural processes — Vitamin E supplementation during pregnancy influenced newborn immune responses without suppressing other necessary immune functions, meaning it helps prevent allergies without weakening overall immunity
- Simple dietary changes have big impact — Eating more pasture-raised eggs, grass fed beef liver, avocados, and wild-caught fish will provide the necessary levels of vitamin E to support immune balance in both mother and baby
Vitamin E, while not as popular as other vitamins, nevertheless plays an important role in human health. According to the National Library of Medicine, vitamin E helps form red blood cells, metabolizes vitamin K properly and facilitates communication between different cells.
But more importantly, vitamin E supports the immune system — especially when it comes to improving food allergy tolerances in early life. This discovery was published in a February 2025 study in The Journal of Immunology.
