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.

Knee pain relief
As a 50-year-old man, I initially thought cod liver oil was for older folks. After two years of use, I discovered it significantly relieves my knee pain. I take a teaspoon every morning, and after a month, the pain during movement vanished. If I run out, I notice a return of discomfort, so I consistently reorder it. Although the taste can be off-putting, the benefits for knee pain outweigh that.

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.
Cod liver oil is a nutritional supplement derived from the liver of codfish, primarily the Atlantic cod (Gadus morhua). This oil is rich in omega-3 fatty acids, specifically EPA and DHA, which are essential for heart and brain health. Additionally, cod liver oil is an excellent source of vitamins A and D, which play critical roles in immune function, vision, and bone health. Often available in liquid form or as softgel capsules, it has been used for centuries as a natural remedy to support overall wellness.
In recent years, cod liver oil has gained popularity as a supplement among health enthusiasts seeking to boost their intake of these vital nutrients. However, it’s essential to consult with a healthcare professional before adding cod liver oil to your daily regimen, especially for those who are pregnant, breastfeeding, or taking other medications. While it can offer considerable health benefits, potential vitamin toxicity and fish allergies are factors to consider. As always, sourcing high-quality cod liver oil from reputable brands ensures you are receiving a product that's free from harmful contaminants and delivers the intended health benefits.
While cod liver oil is renowned for its high levels of omega-3 fatty acids and vitamins A and D, its effectiveness in combating the common cold specifically is not well-established. Some studies suggest that omega-3 fatty acids can support immune health, which might help the body fend off infections, including the cold virus. However, direct evidence linking cod liver oil supplementation to a reduction in cold symptoms or duration is limited.
If you're considering adding cod liver oil to your regimen during cold season, it's important to note that it should not replace traditional prevention methods, such as frequent handwashing and maintaining a healthy diet. Always consult with a healthcare professional before starting any new supplement, especially if you have pre-existing health conditions or are taking other medications. Overall, while cod liver oil may offer ancillary health benefits, it shouldn't be viewed as a primary treatment or preventive measure against the common cold.
Based on user reviews regarding the use of cod liver oil for common cold relief, results can generally be observed within a couple of weeks. For instance, one user noted that after two weeks of use, their mother found relief from stomach issues, indicating a positive response that typically aligns with the body's immune adjustments when taking such supplements Read Review. Other users highlighted similar quick improvements in health; for example, another individual mentioned feeling a slight improvement after just two weeks of taking the supplement Read Review.
Many users also reported that long-term use resulted in fewer illnesses, suggesting that while immediate effects might be subtle, the cumulative benefits over time could significantly enhance the immune system's function against the common cold. For continual use, families noted improved resistance to colds after integrating it into their daily routines Read Review. Overall, while individual experiences may vary, you might expect to start seeing results within about two weeks, with more significant benefits realized through consistent long-term consumption.
This supplement is somewhat supported by scientific research in the context of the common cold, particularly regarding its effects on infants. A study investigating the effects of prenatal docosahexaenoic acid (DHA) supplementation demonstrated that infants whose mothers consumed DHA during pregnancy had fewer cold symptoms and shorter durations of cough and wheezing by the one-month mark. Specifically, the study found that the group receiving DHA experienced a 26% shorter duration of cough and a 30% reduction in the duration of wheezing compared to those given a placebo [1].
Moreover, by the time these infants reached three months, they were reported to be ill for 14% less time overall, indicating potential long-term benefits of DHA on infant health regarding common cold symptoms. While this study highlights noteworthy outcomes, it's crucial to note that these benefits were largely observed in infants and may not directly translate to adults or broader populations dealing with the common cold. Therefore, while the evidence suggests prenatal DHA might positively influence infant cold incidence and symptom duration, further research would be beneficial to better understand its effects in different demographics.

I've ordered this product twice; although it's not always available, it has proven effective. My family drinks it together, and the children get sick less often. I appreciate that it contains no flavourings, as I previously experienced heartburn with lemon-flavoured options. I highly recommend it.

Improved appetite
10 people found this helpful
To be honest, it is excellent in all its flavours. I ordered it a month ago as it was prescribed for me due to infections and ulcers in the stomach, duodenum, intestines, and inflammation of the liver and gallbladder. Since starting to use it, I have felt much better and have begun to eat in reasonable proportions. I now have energy, thanks to God. I will continue to buy it until I am fully healed. It is effective for healing, but for those who struggle with its strong taste, I recommend filling empty capsules and keeping them in a dark, sealed container. I wish everyone a speedy recovery.

DHA reduces infant cold symptoms
Prenatal docosahexaenoic acid supplementation and infant morbidity: randomized controlled trial.
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.

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.
