Flaxseed Oil — Nutrients, Health Benefits, and Shopping Tips

When choosing flaxseed oil, it should be stored in a dark, opaque bottle to protect it from light damage. The oil should have a mild, nutty flavor. Check that it's cold-pressed and organic for maximum health benefits.

Avoid flaxseed oil that smells rancid or bitter, as these are signs it has oxidized. Quality flaxseed oil should be fresh-tasting and not overpower the flavors of the foods it's paired with.

Flaxseed oil should be kept in the refrigerator to stay fresh. Store it in a dark, airtight bottle to prevent oxidation. Properly stored, flaxseed oil can last up to two months.

Exposure to light, heat, and air can cause flaxseed oil to become rancid. Keeping it away from direct sunlight and heat sources is essential. Ensuring the bottle is tightly sealed will help maintain its nutritional value and flavor.

Flaxseed oil can last for 6-12 months when stored in a cool, dark place. Once opened, it should be refrigerated and used within 6-8 weeks for the best quality. Always check for any off smells or changes in texture before using.

Leftover flaxseed oil can be used in a variety of culinary and non-culinary ways. In the kitchen, it’s best used as a finishing oil, drizzled over salads, smoothies, or yogurt, since heating it can degrade its beneficial omega-3 fatty acids. It can also be mixed into salad dressings or blended into dips and spreads for a nutritional boost.

Beyond cooking, flaxseed oil has several uses in personal care and household applications. It’s commonly used in DIY beauty treatments; for instance, it can be applied directly to the skin as a moisturizer or added to homemade face masks to help soothe and hydrate the skin. Flaxseed oil can also be used as a hair treatment to add shine and reduce frizz. Additionally, it’s used in wood finishing as a natural, non-toxic oil for treating cutting boards, wooden utensils, and furniture, helping to protect and preserve the wood.

Flaxseed oil is a plant-based source of omega-3 fatty acids, which support heart health by lowering cholesterol and reducing inflammation.

Additionally, it may aid in digestive health by helping to reduce constipation and promote bowel regularity when consumed regularly.
