Introduction
Cholesterol is a waxy substance that is essential for many bodily functions, but high levels of cholesterol can increase the risk of heart disease. Fish oil and flaxseed oil are both natural sources of omega-3 fatty acids, which have been shown to lower cholesterol levels.
Fish Oil
Fish oil is a type of fatty oil that is derived from the tissues of oily fish, such as salmon, tuna, and mackerel. It is a rich source of omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
Benefits of Fish Oil for Cholesterol
Numerous studies have shown that fish oil can lower cholesterol levels. A meta-analysis of 79 studies found that fish oil supplements reduced total cholesterol by an average of 5.6 mg/dL and LDL cholesterol (the “bad” cholesterol) by an average of 4.3 mg/dL.
Fish oil may also help to raise HDL cholesterol (the “good” cholesterol). A study published in the American Journal of Clinical Nutrition found that people who took fish oil supplements for 8 weeks had a significant increase in HDL cholesterol levels.
Flaxseed Oil
Flaxseed oil is a type of vegetable oil that is derived from the seeds of the flax plant. It is a rich source of omega-3 fatty acids, particularly alpha-linolenic acid (ALA). ALA is converted to EPA and DHA in the body, but the conversion rate is relatively low.
Benefits of Flaxseed Oil for Cholesterol
Flaxseed oil has also been shown to lower cholesterol levels, although the effects are not as pronounced as those of fish oil. A meta-analysis of 27 studies found that flaxseed oil supplements reduced total cholesterol by an average of 2.4 mg/dL and LDL cholesterol by an average of 1.5 mg/dL.
Flaxseed oil may also help to raise HDL cholesterol levels. A study published in the journal Lipids found that people who took flaxseed oil supplements for 12 weeks had a significant increase in HDL cholesterol levels.
Fish Oil vs Flaxseed Oil: Which is Better?
Both fish oil and flaxseed oil can lower cholesterol levels, but fish oil is more effective than flaxseed oil. This is because fish oil contains EPA and DHA, which are more potent than ALA in lowering cholesterol levels.
If you are looking for a natural way to lower your cholesterol, fish oil is the better choice. However, if you are vegan or vegetarian, flaxseed oil is a good alternative.

Conclusion

If you are considering taking fish oil or flaxseed oil supplements, talk to your doctor to discuss the potential benefits and risks.
