What Does Flaxseed Oil Do to Your Body and Are There Side Effects?

Flaxseed oil is full of omega-3 and omega-6 fatty acids. Let’s look at the good effects it can have on your health, as well as any possible negative effects.

Flaxseed oil is obtained from the seeds of the flax plant, known for its rich omega-3 and omega-6 fatty acids. It is valued as one of the few plant-based sources of essential fatty acids.

Flax, also known as Linum usitatissimum, has a rich history dating back centuries, with some fascinating research indicating that this versatile crop was cultivated as early as 30,000 years ago. The early applications of flax were diverse, with one of its primary uses being the production of fabric for clothing. Over time, its applications expanded, encompassing its use as a valuable food source.

The utilization of flaxseed is multifaceted, with the seeds being employed in their whole grain form or in their crushed state. Additionally, the crushed or powdered form of flaxseed is a key ingredient in the production of flour. Moreover, flaxseed oil, containing alpha-linolenic acid (ALA), plays a significant role in promoting wellness. ALA, an omega-3 fatty acid, is considered essential for the body, as it fulfills crucial functions vital to overall health. Despite its importance, the body is unable to produce these essential oils independently, underscoring the significance of including them in one’s diet.

A notable attribute of flaxseed oil is its role in the synthesis of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are pivotal fatty acids essential for numerous physiological processes. These fatty acids play a critical role in diverse functions such as fetal growth, as well as in the intricate workings of neurological, retinal, and immune processes. Notably, one of the areas where these omega-fatty acids offer exceptional benefits is in the enhancement of heart health.

The process of preparing flaxseed oil involves cold-pressing dry and fresh flax seeds. This method is particularly advantageous, as it helps to safeguard the essential antioxidants present in the seeds, a benefit that can be lost during traditional heating processes. Therefore, the preservation of these vital antioxidants underscores the significance of the cold-pressing method in retaining the nutritional value of flaxseed oil.

Flaxseed oil nutrition facts

Flaxseed may have anti-inflammatory properties

The high omega-3 fatty acid content in flaxseed oil is linked to anti-inflammatory effects. Research indicates that flaxseed oil reduces the levels of C-reactive protein (CRP), an important marker for inflammation, in obese individuals.

Higher levels of CRP indicate increased inflammation, while lower levels are linked to reduced inflammation. Further research is necessary to understand the specific mechanisms of flaxseed oil and its potential impact on non-obese individuals.

It may reduce the risk of cancer.

Flaxseed oil contains active biological compounds that may reduce the risk of certain types of cancers. Linoorbitides, a group of molecules found in flaxseed oil, have antioxidant and antitumor properties. A 2015 study discovered that these linoorbitides have cytotoxic effects on breast cancer cells. Application of linoorbitides directly to the affected area was found to be a more practical way to utilize their anticancer effects, as orally consuming them would require very high quantities that the body may not be able to absorb.

It significantly enhances heart health.

One of the most widely accepted benefits of flaxseed oil is its positive effect on heart health. Scientific studies have established the vital role of omega-3 fatty acids in improving cardiovascular activity by making more EPA and DHA available, promoting essential bodily functions. One study indicated that EPA and DHA can considerably lower the risk factors linked to heart conditions, including lower levels of blood triglyceride, reduced risk of heart attacks, lower blood pressure, and the collection of platelets.

It could definitely improve gut health

• Flaxseed oil has laxative effects that can improve gut health by removing waste particles.
• A study involving 50 hemodialysis patients found that daily consumption of flaxseed oil may help relieve constipation.
• Another study with 31 participants found that flaxseeds were beneficial for people with irritable bowel syndrome (IBS), reducing symptoms such as constipation and diarrhea.

Enhancing Skin Health

ALA is commonly used in cosmetic products for its antioxidant properties. Research suggests that flaxseed oil can decrease inflammation of skin cells and aid in skin cell regeneration. Flaxseed oil contains polyunsaturated fatty acids which promote wound healing and contribute to its antioxidant effects.

Side effects of flaxseed oil

Some dietary supplements may have side effects. It’s recommended to take supplements like flaxseed oil under the supervision of a qualified doctor.

May Impede Absorption of Medication

Some studies suggest that flaxseed oil could delay or reduce the absorption of oral medicines and other supplements. To prevent this, it is recommended to space out the intake of medications or supplements and flaxseed oil.

May potentially exacerbate certain health conditions.

Some studies suggest that diets rich in ALA may be associated with an increased risk of macular degeneration and prostate cancer, but further research is needed to confirm this. In such cases, doctors may advise obtaining EPA and DHA from other dietary sources, such as fish.

This topic may have an impact on pregnancy.

Pregnant women should avoid taking flaxseed oil, as some studies found that it may increase the incidences of premature birth.

It’s important for expectant mothers to be cautious about the supplements they consume, as certain substances may have a significant impact on their health and the well-being of their unborn child. In the case of flaxseed oil, research suggests that it could potentially elevate the risk of premature birth, which is a crucial consideration for pregnant women and their healthcare providers. It’s advisable for pregnant women to consult with their healthcare professionals to discuss the potential risks associated with the use of flaxseed oil and to explore alternative options that promote a safe and healthy pregnancy.

May lead to elevated blood loss

Research has found that flaxseed oil should be avoided before surgeries due to its blood-thinning effects, which can lead to excessive blood loss. The Department of Anesthesiology & Pain Medicine at the University of Washington advises stopping the intake of such supplements at least seven days before surgery. If planning to undergo surgery, it’s essential to consult a doctor about the timeline for stopping and restarting flaxseed supplements.
