When you think of “healthy oils,” olive oil or coconut oil might come to mind. But there’s another powerful oil that often flies under the radar — flaxseed oil. Extracted from the seeds of the flax plant (Linum usitatissimum), this golden oil has been cherished for centuries for its impressive nutritional and therapeutic benefits.
From improving heart health to nourishing your skin and hair, flaxseed oil (also known as linseed oil) is a true multitasker in the world of natural wellness. Whether you consume it directly, use it in your diet, or apply it topically, flaxseed oil offers numerous advantages backed by science. Let’s explore everything you need to know about this nutrient-rich oil — from its nutrition facts and benefits to its dosage, side effects, and how to use it effectively.
What is Flaxseed Oil?
Flaxseed oil is extracted from flax seeds, tiny brown or golden seeds that are considered one of the richest plant sources of omega-3 fatty acids, especially alpha-linolenic acid (ALA). It’s obtained through a process called cold pressing, which helps retain the nutritional value of the seeds.
Unlike flaxseeds, which contain fiber and lignans, the oil focuses mainly on healthy fats — making it ideal for those looking to boost their omega-3 intake without adding extra fiber to their diet. It’s commonly used in cooking (in non-heated recipes), as a dietary supplement, and as a skincare or haircare remedy due to its anti-inflammatory and moisturizing properties.
Nutrition Facts of Flaxseed Oil
Here’s a nutritional profile of 1 tablespoon (13.6 g) of flaxseed oil:

Is flaxseed oil safe for daily use?
Yes, moderate daily use (1–2 tablespoons) is generally safe for most people.
Can flaxseed oil be used for cooking?
It’s best used in cold dishes or added after cooking to preserve nutrients. Avoid frying or baking with it.
Is flaxseed oil good for skin and hair?

How long does flaxseed oil last?
Typically 6–8 months if stored properly in a cool, dark place or refrigerator.
Can children take flaxseed oil?
Yes, in small amounts (about 1 teaspoon daily) under parental supervision.
What is flaxseed oil good for?
Flaxseed oil is excellent for heart, skin, hair, and overall wellness. It’s rich in omega-3 fatty acids, which help reduce inflammation, support heart health, and improve cholesterol levels. It also promotes glowing skin, shiny hair, better digestion, and improved brain function.
Which is better to lower cholesterol, fish oil or flaxseed oil?
Both are beneficial, but fish oil is generally more effective for lowering cholesterol because it contains EPA and DHA, the active forms of omega-3s that directly support heart health. However, flaxseed oil is an excellent plant-based alternative for vegetarians and vegans, as it provides ALA (alpha-linolenic acid), which the body can partially convert into EPA and DHA.
How long does it take for flaxseed oil to start working?
The benefits of flaxseed oil usually become noticeable after 2 to 6 weeks of consistent use. Improvements in skin texture, digestion, and inflammation may appear sooner, while heart health or cholesterol changes may take a bit longer — around 8 to 12 weeks. Regular use and a balanced diet make a big difference in how quickly you see results.
Which is better, coconut oil or flaxseed oil?
It depends on your goal. Flaxseed oil is better for heart health, brain function, and reducing inflammation because of its high omega-3 content. Coconut oil, on the other hand, is richer in medium-chain triglycerides (MCTs), which can boost energy and metabolism. For everyday wellness and cholesterol management, flaxseed oil is generally the better choice.
What to look for when buying flaxseed oil?
When buying flaxseed oil, look for:
- Cold-pressed or expeller-pressed oil (retains nutrients)
- Dark glass bottles (protects from light damage)
- Refrigerated storage (prevents oxidation)
- Fresh manufacture date (flaxseed oil spoils quickly)
- Organic and non-GMO labels (ensures purity and safety)
Avoid oils with a strong, fishy, or sour smell — that’s a sign it’s gone rancid.
What is better than flaxseed oil?
“Better” depends on what you need. For pure omega-3 power, fish oil or algae oil may be more effective because they provide direct EPA and DHA. But if you prefer a vegan, plant-based option, flaxseed oil remains one of the best choices. Other good alternatives include chia seed oil, hemp seed oil, and walnut oil, which also offer healthy fats and antioxidants.
What is the best way to use flaxseed oil?
The best way to use flaxseed oil is raw and unheated. Add 1–2 teaspoons daily to smoothies, salad dressings, dips, or yogurt. You can also apply it topically for skin hydration or mix it with carrier oils for hair nourishment. Avoid using flaxseed oil for frying or baking, as heat destroys its beneficial omega-3 fats.
