Flaxseed oil may offer relief for people suffering from dry eye symptoms.
Flaxseed oil, a plant-based source of omega-3 fatty acids, has shown potential benefits in alleviating dry eye symptoms. This is according to current scientific evidence, which suggests that flaxseed oil could support tear production and reduce ocular surface inflammation [1][3].
The omega-3 fatty acid found in flaxseed oil, alpha-linolenic acid (ALA), may help improve the quality and stability of the tear film. This could reduce tear evaporation and alleviate dryness symptoms [3].
Some clinical studies on omega-3 fatty acids, including those from flaxseed oil and fish oil, have demonstrated a reduction in ocular surface inflammation and improved tear production [1][3]. However, it's important to note that fish oil alone has not consistently shown benefit for dry eye in all trials.
Supplement formulations that combine omega-3s with other nutrients may have synergistic effects, but these require further validation [1][2]. The evidence does not currently support fish oil supplements alone as effective for dry eye, suggesting that the plant-based omega-3s in flaxseed oil might play a different or complementary role compared to marine-based omega-3s [1].
The quality, dosage, and freshness of flaxseed oil supplements are crucial factors for their efficacy, as there is a risk of oxidation and degradation of fatty acids [3].
While flaxseed oil shows promise, it's essential to remember that the scientific consensus emphasizes the need for more well-designed clinical trials to confirm these findings, specify effective doses, and compare flaxseed oil's efficacy to other omega-3 sources and treatments for dry eye [1][2][3].
Dry eye affects a significant number of Americans each year. If you are considering using flaxseed oil to treat dry eye, it's advisable to consult a healthcare professional first. It's also important to take flaxseed oil with plenty of water to try and prevent potential side effects such as gastrointestinal problems like constipation and diarrhea [2].
It's worth noting that while flaxseed oil is an ingredient in some formulations of artificial tears, the safety and effect of these products require further investigation [3]. A 2020 study investigated the safety and effect of flaxseed oil and trehalose in artificial tears for dry eye, but the results are not conclusive as to whether the protection offered to the eyes came from flaxseed oil, trehalose, or both [4].
Furthermore, it's important to be aware that the manufacturers of the flaxseed oil artificial tears funded the 2020 study and financially supported the researchers [4]. This raises questions about the potential for bias in the results.
In conclusion, while flaxseed oil may offer a potential treatment option for dry eye, more research is needed to confirm its benefits, specify effective doses, and compare its efficacy to other treatments. Always consult a healthcare professional before taking or using flaxseed oil supplements to treat health conditions.
