Rapeseed oil ranks among the top dietary fats worth including in your daily routine. Beyond its pleasant, mild taste, it offers a compelling nutritional profile that benefits almost anyone — supporting the heart, joints, and vision, contributing to healthy cholesterol levels, and performing double duty as both a kitchen staple and a hair care ingredient. But not all rapeseed oils are equal. Here is what to look for — and why the right choice makes all the difference.
What Is Rapeseed Oil and Where Does It Come From?
Rapeseed oil is pressed from the seeds of selected varieties of the Brassica napus plant. Historically it had a poor nutritional reputation due to high levels of erucic acid, a compound associated with adverse health effects. Modern cultivated varieties — used in all food-grade rapeseed oil today — have been bred to contain negligible amounts of erucic acid, transforming it into one of the most nutritionally balanced plant oils available.
The method of extraction determines both the nutritional value and the culinary application. Cold-pressed, unrefined rapeseed oil is pressed at temperatures below 40°C, preserving its natural fatty acid profile, fat-soluble vitamins, and characteristic golden colour. This version is best used raw — in dressings, dips, and finishing sauces. Refined rapeseed oil, processed at high temperatures with chemical solvents, has a higher smoke point and greater stability under heat, making it suitable for frying and baking — though much of the nutritional complexity is lost in the process.
[tip:For maximum nutritional benefit, look for rapeseed oil labelled "cold-pressed" and "unrefined," ideally from the first pressing. This means the seeds were pressed only once at low temperature — producing an oil with the highest concentration of omega fatty acids, vitamin E, and vitamin K.]Rapeseed Oil: Nutritional Benefits
What sets rapeseed oil apart from most other culinary oils is its exceptional omega-3 to omega-6 ratio. Most plant oils are dominated by omega-6 fatty acids, which — when consumed in excess relative to omega-3 — may contribute to inflammatory processes in the body. Rapeseed oil naturally contains both in a ratio close to 2:1 (omega-6 to omega-3), which is closer to the recommended nutritional balance than sunflower, corn, or soybean oil.
Its key nutritional contributions include:
- Oleic acid (omega-9) — a monounsaturated fatty acid that may help maintain normal blood cholesterol levels and support cardiovascular health
- Alpha-linolenic acid (ALA, omega-3) — a plant-based essential fatty acid that contributes to normal heart function
- Vitamin E — a fat-soluble antioxidant that helps protect cells from oxidative stress and may slow skin ageing
- Vitamin K — supports normal blood clotting and bone metabolism
- Vitamin A precursors (beta-carotene) — contributes to the maintenance of normal vision
These properties make rapeseed oil a useful dietary addition for those looking to support cardiovascular health through everyday nutrition. For higher-dose omega-3 supplementation beyond what diet alone can provide, concentrated fish or algae oil supplements remain the more effective route — explore our omega-3 and fish oil range for comparison.
Cold-Pressed vs Refined: Which Rapeseed Oil to Choose?
The choice largely depends on how you plan to use it. Cold-pressed, unrefined rapeseed oil from the first pressing is the nutritionally superior option — ideal for salad dressings, drizzling over roasted vegetables, making vinaigrettes, or adding raw to porridge. It has a slightly nutty, grassy flavour and a characteristic dark-gold colour from its natural carotenoids. It should not be heated beyond moderate temperatures, as heat degrades the polyunsaturated fatty acids.
Refined rapeseed oil trades nutritional complexity for thermal stability. Its higher smoke point (around 200–220°C) makes it the more practical choice for stir-frying, roasting, and baking. If your primary use is cooking at high heat, refined oil is the appropriate choice — just understand that its health advantages over other refined oils are more limited than those of its cold-pressed counterpart.
First-pressing, unrefined cold-pressed oil is the gold standard for nutritional quality — look for this designation when buying.

Sunflower oil is rich in vitamin E and widely available, but its fatty acid profile is almost entirely omega-6, with very little omega-3. For most European diets — already high in omega-6 from processed foods — adding more sunflower oil further widens an already imbalanced ratio. Sunflower oil also has a relatively low smoke point in its unrefined form (around 100°C), limiting its cooking utility.
Rapeseed oil, by contrast, offers a more balanced fatty acid profile and performs better under heat in its refined form. For salads, both oils are valid choices based on personal flavour preference. For cooking and frying, rapeseed oil is the stronger option. For raw consumption with maximum nutritional benefit, cold-pressed rapeseed oil is hard to beat among affordable plant oils.
Rapeseed Oil for Hair
Beyond the kitchen, cold-pressed rapeseed oil has a place in hair care — particularly for the practice of hair oiling, which involves applying oil to the hair and scalp to improve moisture retention, reduce porosity, and restore softness and shine. Rapeseed oil's lightweight fatty acid profile makes it suitable for medium-to-high porosity hair, where it can penetrate the hair shaft and help smooth the cuticle layer. It is often used as a more affordable alternative to argan or marula oil for this purpose. The oil can be applied before washing as a pre-wash treatment or used in small quantities on dry ends as a finishing product.
How to Store Rapeseed Oil
Cold-pressed, unrefined rapeseed oil is sensitive to light, heat, and oxygen — all of which accelerate oxidation and turn the oil rancid. Store it in its original dark glass or opaque bottle, sealed tightly, in a cool and dark location away from direct sunlight. Room temperature or slightly cooler is appropriate; refrigeration is not necessary but can extend shelf life. Once opened, cold-pressed rapeseed oil is best used within 3–4 months.
[warning:Do not use cold-pressed, unrefined rapeseed oil for high-heat frying. Its polyunsaturated fat content means it degrades rapidly at high temperatures, producing harmful oxidation products. Use refined rapeseed oil for cooking, and save the cold-pressed version for raw applications.]Other Cold-Pressed Oils Worth Exploring
If you are interested in cold-pressed plant oils more broadly, rapeseed oil is an excellent starting point — but the category is wide. Flaxseed oil offers the highest ALA omega-3 content of any culinary oil, making it a popular supplement for those on plant-based diets. Hemp oil provides a similarly well-balanced omega-6 to omega-3 ratio and a distinctive earthy flavour. Camelina oil is a lesser-known but nutritionally comparable option to rapeseed with a high ALA content.
