Docosahexaenoic acid helps asthmaLipid mediators obtained from docosahexaenoic acid by soybean lipoxygenase alleviate ovalbumin‑induced allergic asthma in mice by reducing airway inflammation and oxidative stress.
Study examines DHA's anti-asthmatic effects
We explored the potential of lipid mediators derived from docosahexaenoic acid (DHA) for alleviating allergic asthma. Using a model where mice were challenged with ovalbumin (OVA) to induce asthma-like symptoms, we administered lipid mediators that included 17S-monohydroxy DHA, resolvin D5, and protectin DX. These treatments led to significant improvements in key aspects of asthma such as reduced inflammatory cell infiltration and lower levels of Th2 cytokines.
Following treatment with the lipid mediators, we observed decreased levels of interleukin-6, tumor necrosis factor-α, and IgE—important markers associated with allergic reactions. There was a notable reduction in inflammation and oxidative stress in lung tissues, which suggests a protective effect on the lungs. Additionally, histological examinations revealed fewer signs of inflammation and mucus secretion.
The results indicate that DHA-derived lipid mediators may effectively mitigate the symptoms of allergic asthma and offer a promising new approach for treatment. They seem to act by reducing inflammation and improving antioxidant defenses within the lungs.

We set out to assess a new extensively hydrolyzed whey-protein formula, which includes docosahexaenoic acid (DHA), for infants with cow's milk allergy (CMA). This study involved 34 children, primarily with IgE-mediated reactions, participating in a double-blind, placebo-controlled food challenge. Remarkably, all the children tolerated the new formula during the trial. This is significant since the American Academy of Pediatrics states that successful tolerance in over 90% of CMA children is crucial for a product to be considered hypoallergenic.
Although our focus was on the overall efficacy and safety of this formula, it's important to note that while DHA was included, we stopped short of isolating its specific impact on allergy outcomes. Thus, while we noted that this new formula is well-tolerated and associated with healthy growth and gastrointestinal tolerability, we cannot definitively state the effect of DHA alone on allergies. We recognize that further research would be needed to explore DHA's specific role in allergy management.

DHA and ARA enhance immune toleranceFeeding Docosahexaenoic Acid and Arachidonic Acid during Suckling and Weaning Contributes to Oral Tolerance Development by Beneficially Modulating the Intestinal Cytokine and Immunoglobulin Levels in an Allergy-Prone Brown Norway Rat Model.
Significant findings on allergy prevention
We explored how adding docosahexaenoic acid (DHA) and arachidonic acid (ARA) in the diets of allergy-prone Brown Norway rats affects allergy responses. Our study involved feeding these essential fatty acids to both mother rats and their pups during the crucial suckling and weaning periods.
By comparing groups that received these supplements to those that did not, we aimed to understand how these dietary changes might influence immune development and oral tolerance—the body’s ability to accept food without triggering an allergy.
At the end of our study, we found that the ARA + DHA supplementation during early life boosted DHA levels in the intestinal fats and increased important immunological markers such as secretory IgA and specific cytokines. This suggests that DHA and ARA may help create an environment in the gut that supports healthy immune responses and reduces allergy risk.
Overall, our findings highlight the potential benefits of these fatty acids for nurturing a more tolerant immune system in the early stages of life.

DHA enhances allergy response mediatorsSex-dependent differential increase of specialized pro-resolving mediators in extracellular vesicles secreted by human primary conjunctival goblet cells during allergic inflammation.
Direct effect on allergic inflammation
We investigated how docosahexaenoic acid (DHA) influences allergic responses in conjunctival goblet cells, the cells that help maintain eye surface health. By stimulating human primary conjunctival goblet cells with histamine, we measured various lipid mediators in the extracellular vesicles they secreted.
Our findings revealed that in the presence of DHA during allergic inflammation, we observed a significant increase in two specialized pro-resolving mediators, LXA4 and RvD1. This increase was especially pronounced in female cells, showing respective fold increases of 5.3 and 6.9, while male responses remained markedly lower with only 0.5 and 0.8.
These results suggest that DHA not only enhances the production of beneficial mediators but also highlights a notable difference between male and female responses to allergic reactions. This novel insight could improve our understanding of allergy treatment, especially regarding why males may experience more severe allergic conjunctivitis.

We examined how docosahexaenoic acid, particularly its metabolite resolvin D2, influences allergic reactions and inflammation. Our focus was on type 2 inflammatory responses, often seen in allergic conditions. Through rigorous methodologies, including control groups, the study assessed how resolvin D2 can help in regulating these responses and promote the resolution of allergy-related inflammation in mice.
Our findings revealed that resolvin D2 plays a significant role in effectively managing allergic inflammation. It helps to mitigate the intense reactions typically associated with allergies, providing a clearer path toward alleviating symptoms.
This research demonstrates the potential of docosahexaenoic acid in offering therapeutic benefits for those suffering from type 2 inflammation due to allergies, and suggests that targeted treatments could improve overall allergen management.

User Reviews
I took Raw Prenatal vitamins throughout my pregnancy and experienced no nausea. I had plenty of energy and needed less sleep than before. My baby was born healthy, and I'm currently taking DHA with the vitamins. The child has no allergies and is developing well; the benefits are clear. I highly recommend this to everyone!

This omega is great for breastfeeding and did not cause any allergies while I was nursing.
Pleasant taste, no allergies
An excellent omega for nursing mothers, with a pleasant taste and subtle fish smell. The DHA dosage is optimal and, importantly, did not cause allergies in my baby!
I took this Omega during my pregnancy and greatly appreciate this manufacturer; it did not cause any allergies.
The product has a mild effect, and I experienced no allergies with it.
