Flaxseed oil: A superfood that supports healthy heart and brain functions

Flaxseed oil has been around since ancient times and was valued by civilizations like the Greeks, Romans and Egyptians for its medicinal benefits. Charlemagne even mandated its consumption for health.
Packed with omega-3 fatty acids (ALA), lignans, vitamin E and a balanced ratio of omega-6 to omega-3, it supports heart health, brain function and reduces inflammation.
It is best consumed raw – drizzled on salads, blended in smoothies or mixed into yogurt. Avoid cooking with it, as heat destroys its delicate nutrients.
While beneficial, flaxseed oil spoils easily and may interact with blood thinners, so proper storage and moderate consumption are key.
Choose cold-pressed, organic flaxseed oil to avoid pesticides and heavy metals and store it in a dark bottle in the fridge to prevent rancidity.

In the world of natural health and holistic nutrition, few ingredients boast the rich history and potent benefits of flaxseed oil. Derived from the seeds of the flax plant (Linum usitatissuum), this golden-hued oil has been revered for centuries for its healing properties and nutritional profile. Packed with essential fatty acids, lignans and antioxidants, flaxseed oil is a powerful natural remedy and dietary supplement that can support optimal health.

Brief history of flaxseed oil

Flaxseed oil, also known as linseed oil, is extracted from the tiny, nutrient-dense seeds of the flax plant. Unlike these seeds, which are consumed ground or whole for their fiber content, flaxseed oil is cold-pressed to retain its omega-3 fatty acids (ALA – alpha-linolenic acid), lignans and other bioactive components. Flaxseed has a rich history dating back thousands of years, with evidence of it being cultivated as early as 3,000 BCE in ancient Babylon and Mesopotamia, where it was used for both clothing and medicinal purposes. The ancient Egyptians, Greeks and Romans also valued flaxseed for its digestive and skin health benefits. Hippocrates and Theophrastus documented its therapeutic properties, while in the 8th century, Charlemagne recognized its importance by mandating its consumption among his subjects for overall health. Flaxseed remained a staple in Europe before being introduced to North America during the colonial era. Although its use declined during industrialization, flaxseed and flaxseed oil experienced a resurgence in the late 20th century as modern research affirmed their cardiovascular and anti-inflammatory benefits, reinforcing their enduring role in wellness and nutrition.

Nutritional profile and health benefits

Flaxseed oil is one of the richest plant-based sources of omega-3 fatty acids, which are essential for brain function, heart health and inflammation control. (Related: Study: Flaxseed oil shown to reduce blood pressure.) These are the key nutrients in flaxseed oil and their health benefits:

Omega-3 fatty acids (ALA) - support heart health, reduce inflammation and promote healthy brain function
Lignans - phytoestrogens with antioxidant and hormone-balancing properties
Vitamin E - a powerful antioxidant that protects cells from oxidative damage
Omega-6 fatty acids - occurs in flaxseed oil in a balanced ratio with omega-3 to support optimal cellular health
Omega-9 fatty acids (oleic acid) - a healthy fatty acid with anti-inflammatory and anticancer properties

Flaxseed oil's high alpha-linolenic acid (ALA) content supports cardiovascular health by reducing LDL ("bad") cholesterol and blood pressure while preventing blood clots. Additionally, its anti-inflammatory properties make it useful for addressing conditions like arthritis, autoimmune disorders and skin health. The omega-3s in flaxseed oil also promote optimal brain function by aiding memory and cognitive clarity, while lignans (though reduced in oil form compared to whole seeds) help regulate estrogen levels. Considerations Flaxseed oil is widely regarded as beneficial for health when used appropriately, but you should consider the following to enjoy its potent benefits upon consumption:

Unlike oils used for high-heat cooking (such as olive or coconut oil), flaxseed oil is highly sensitive to heat and oxidation. It is best used raw in salad dressings and smoothies, drizzled over cooked grains or roasted vegetables, and mixed into yogurt or oatmeal.
Avoid frying or baking with flaxseed oil, as high temperatures can degrade its delicate fatty acids, potentially producing harmful compounds.
Flaxseed oil is highly susceptible to oxidation and can turn rancid quickly if exposed to light, heat or air, which may negate its benefits or even cause harm. Keep flaxseed oil in a dark glass bottle in the refrigerator to prevent rancidity.
Rare allergic reactions are possible, particularly in individuals with seed allergies.
Due to its blood-thinning effects, high doses may interact with anticoagulant medications, requiring caution in such cases.

When stored properly and consumed in moderation, flaxseed oil is a safe and highly nutritious addition to a balanced diet, offering numerous health advantages for most people.

Why choose organic flaxseed oil

Non-organic flaxseed crops may be treated with harmful pesticides like glyphosate (linked to hormonal disruption) and phthalimides (fungicides). The soil in some fields where flaxseed is grown may also contain heavy metals such as cadmium and lead. Opting for organic, cold-pressed, unrefined flaxseed oil ensures a cleaner, higher-quality product that's free of these contaminants.

Recipes with flaxseed oil

Flaxseed oil's nutty, slightly grassy flavor makes it a delicious addition to many healthy dishes, such as:

Flaxseed oil vinaigrette

Combine flaxseed oil, apple cider vinegar, Dijon mustard, honey and garlic.

Superfood smoothie boost

Blend flaxseed oil with banana, berries, spinach and plant-based milk.

Drizzled over avocado toast

Mix with sea salt and chili flakes for a heart-healthy breakfast.

Omega-3 chia pudding

Combine chia seeds, almond milk and flaxseed oil for a nutrient-packed dessert. This story is not medical advice and is not intended to treat or cure any disease.
