We conducted a double-blind randomized controlled trial to understand how prenatal supplementation of docosahexaenoic acid (DHA) might influence infant health, particularly concerning the common cold. Pregnant women were given either a daily dose of 400 mg of DHA or a placebo starting at 18 to 22 weeks of gestation until childbirth.
Caregivers then reported on their infants’ health at 1, 3, and 6 months, sharing details about common illness symptoms. We found that DHA supplementation appeared to reduce the number of colds at one month and also seemed to lessen the duration of various cold symptoms in infants. Specifically, infants in the DHA group experienced fewer cold symptoms and had shorter durations of cough and wheezing.
While the overall occurrence of specific illness symptoms was similar between the DHA and placebo groups, DHA did bring about noteworthy benefits. At 1 month, infants in the DHA group had a 26% shorter duration of cough and 30% shorter wheezing; however, they experienced a longer duration of rash.
Furthermore, by the time the infants reached 3 months, those whose mothers took DHA were ill for 14% less time overall. At 6 months, the DHA group showed significantly reduced durations of several illness indicators, although they did experience longer episodes of vomiting.
This study suggests that prenatal DHA not only seems to impact the occurrence of colds in children but may also play a role in the duration of symptoms over the first half-year of life.

Omega-3 effects on viral infections
Rationale and design of the pragmatic randomized trial of icosapent ethyl for high cardiovascular risk adults (MITIGATE).
We examined the MITIGATE study, focusing on the effects of icosapent ethyl (IPE), a purified omega-3 fatty acid, in adults with cardiovascular disease at risk for viral upper respiratory infections.
With about 16,500 participants, this clinical trial compared IPE treatment against usual care. The goal was to see if IPE could lessen the severity and impact of viral infections over six months.
Unfortunately, there was no significant evidence found that IPE improved outcomes for upper respiratory infections in this group.

DHA/ARA reduces colds and allergies
The impact of early nutrition on incidence of allergic manifestations and common respiratory illnesses in children.
We investigated whether feeding infants formula supplemented with docosahexaenoic acid (DHA) and arachidonic acid (ARA) could impact the development of allergies and respiratory illnesses until age three.
In a well-structured, randomized, double-blind study, we followed children who received either supplemented or nonsupplemented formulas during their first year of life. Our findings showed that those on the DHA/ARA formula had significantly lower chances of developing upper respiratory infections and common allergic diseases.
Notably, the DHA/ARA group experienced a delayed onset and reduced incidence of respiratory issues, indicating potential benefits of early nutrition on long-term health.

Significant coldness relief

The common cold is a viral infection of the upper respiratory tract, primarily affecting the nose and throat. It's caused by a variety of viruses, with rhinoviruses being the most prevalent. Symptoms generally include a runny or stuffy nose, sore throat, cough, sneezing, mild headache, and sometimes a low-grade fever. While the common cold is often mild and resolves on its own within a week or two, it can still be bothersome and impact daily activities.
Transmission occurs through respiratory droplets when an infected person coughs or sneezes, or by touching surfaces contaminated with the virus. Preventative measures include frequent handwashing, using hand sanitizer, and avoiding close contact with infected individuals. Since there is currently no cure for the common cold, treatment focuses on symptom relief through over-the-counter medications, adequate rest, and hydration. While colds may be uncomfortable, they are generally not serious; however, seeking medical attention may be necessary if symptoms worsen or persist for an extended period.
Omega-3 fish oil is a nutritional supplement derived from the fatty tissues of fish, particularly fatty fish like salmon, mackerel, and sardines. It is rich in omega-3 fatty acids, which are essential fats that the body cannot produce on its own. The most significant types of omega-3s found in fish oil are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both of which are known for their numerous health benefits. These include reducing inflammation, supporting heart health, and promoting brain function.
Incorporating omega-3 fish oil into your diet can be beneficial if you don’t consume enough fish regularly. Many health experts recommend oily fish as a part of a balanced diet due to their high omega-3 content. For those who find it difficult to include fish in their meals, fish oil supplements can offer a convenient alternative, providing the same essential fatty acids in concentrated form. However, it’s essential to choose high-quality supplements that are third-party tested for purity and potency to avoid contaminants such as heavy metals or other toxins that can impact health.
Based on user reviews, the time it typically takes to see results from taking Omega-3 supplements for common cold-related benefits varies significantly among users. Many reviewers report noticeable improvements within a month; for instance, one customer mentioned experiencing better immunity and fewer colds after just a month of use Read Review. Others, however, indicate longer timelines, with noticeable benefits coming after several months of consistent use. A reviewer highlighted that after three months, they felt less affected by colds, while another user mentioned improved health after around four months Read ReviewRead Review.
Moreover, some users assert that continued Omega-3 supplementation contributes to overall wellness, including better energy levels and fewer colds, which may indicate that sustained use is beneficial for enhancing immunity over time Read Review. While initial improvements can occur in a matter of weeks, fully realizing the potential benefits may require a more extended supplementation period. As always, individual responses can vary, making it essential to assess how your body reacts to the supplement over time.
The scientific research provides mixed insights on the efficacy of specific supplements for managing the common cold. For instance, while a study examining the effects of icosapent ethyl (a purified omega-3 fatty acid) on viral infections in heart patients did not find significant benefits in reducing the severity of upper respiratory infections [1]. On the other hand, research on docosahexaenoic acid (DHA), particularly in infant studies, shows more promise. Infants fed formula supplemented with DHA and arachidonic acid (ARA) experienced a significantly lower incidence of respiratory infections and allergies, indicating a potential protective effect against conditions related to the common cold [2].
Additionally, prenatal DHA supplementation appears to positively influence infants' health concerning the common cold. A study found that mothers who took DHA during pregnancy reported fewer colds in their infants, alongside a decrease in the duration of symptoms like cough and wheezing [3]. This suggests that while adult formulations of omega-3s may not offer significant advantage for the common cold, prenatal and early-life supplementation with DHA could provide beneficial effects in managing respiratory illnesses in infants.
Users have reported a variety of improvements in their symptoms after using Omega-3 supplements, particularly related to immune function and overall well-being. Many individuals claim to have experienced a significant reduction in the frequency of colds. For instance, one user noted that after four months of consistent use, they hadn’t caught a common cold, attributing their improved immunity to the supplement Read Review. Another user also echoed this sentiment, stating that their husband hardly got sick throughout the winter after taking Omega-3 Read Review.
In addition to enhanced immunity, several users reported improvements in energy levels and general health. A customer mentioned feeling more energized and finding it easier to wake up after only a few days of supplementation Read Review. Others highlighted benefits beyond immunity, such as better skin hydration and reduced coldness, particularly during winter months Read Review. Overall, users appear to find Omega-3 beneficial for both preventing common illnesses and enhancing their daily vitality, although individual responses can vary widely.
Users have noted the effectiveness of combining Omega-3 with other supplements to manage common cold symptoms and enhance overall health. For instance, several reviewers mentioned taking Omega-3 in conjunction with vitamin B and kalmag, reporting improved warmth and reduced coldness during winter months Read Review. Another user highlighted that their overall health improved through Omega-3 and other supplements, despite not seeing significant hormonal changes, indicating the potential benefits of a multi-supplement approach Read Review.
Additionally, some reviewers observed that Omega-3 supplementation significantly improved their immunity, leading to fewer instances of cold, even during winter Read Review. The combination of Omega-3 with other health strategies appears to have created a beneficial synergy for users, enhancing their resistance to illnesses and overall vitality Read Review. These insights suggest that incorporating Omega-3 alongside other supplements can provide a comprehensive approach to wellness and cold management.
Based on user reviews, there appears to be a consensus on the effectiveness of Omega-3 Fish Oil in reducing the incidence and severity of common colds. Various users have reported taking Omega-3 with positive results, including fewer colds and improved overall health. For instance, one user mentioned taking two capsules twice daily and noted a noticeable decrease in shortness of breath and cold frequency Read Review. Another user, emphasizing consistency, stated they took one capsule daily, contributing to their family's resilience against the common cold seasons Read Review.
Additionally, some reviews indicated that after a course of Omega-3, users experienced not only fewer colds but also general improvements in health markers such as immunity and energy levels Read ReviewRead Review. Users typically suggested varying dosages from one to two capsules daily, with higher frequencies seeming beneficial for particular individuals Read Review. Overall, daily supplementation of Omega-3 seems to support enhanced immunity and reduced cold incidence among users.

Bought this for my husband and me, and we adore it! After a month of use, we've noticed our immunity improving, as we rarely catch the common cold. My skin looks more radiant and dewy. They are easy to swallow despite their size, and the quality is excellent at an economical price.
