Sunflower oil is arguably the most widely recognised cooking oil in Europe. Most people associate it primarily with the kitchen, as it has been a staple ingredient in everyday cooking for generations. It might seem like everything there is to know about sunflower oil is already common knowledge — but this familiar pantry essential actually holds a number of health-related secrets that are well worth discovering.
Where Does Sunflower Oil Come From and What Does It Contain?
Sunflower oil is produced from the seeds of the sunflower plant (Helianthus annuus), which was brought to Europe by the Spanish in the early 16th century. Since then, it has become deeply rooted in European culinary traditions and remains a fixture in kitchens across the continent.
What makes sunflower oil nutritionally interesting is its composition. It is an exceptionally rich source of vitamin E — containing approximately 39 mg per 100 g of product. This is one of the highest concentrations of vitamin E found in any food oil. Vitamin E is a powerful antioxidant that helps protect cells from oxidative stress caused by free radicals, and it plays a role in supporting skin health, circulation, and muscle function. If you are interested in boosting your vitamin E intake through supplementation, explore our vitamin E collection.
Beyond vitamin E, sunflower oil contains phytosterols — plant compounds that may support healthy cholesterol levels. The oil's fatty acid profile is dominated by polyunsaturated fatty acids (mainly omega-6 linoleic acid), along with monounsaturated fats, a small amount of saturated fats, and trace trans isomers. Unrefined sunflower oil is particularly valued for its higher nutritional content and more natural composition.

When consumed in appropriate amounts as part of a balanced diet, sunflower oil may offer a range of health benefits. Its rich antioxidant and fatty acid profile means it touches on multiple body systems.
Cardiovascular support: The omega-6 fatty acids and phytosterols in sunflower oil may contribute to maintaining healthy cholesterol levels and supporting normal heart function. These compounds have long been associated with cardiovascular wellbeing in nutritional research. For those looking into broader heart health support, our cardiovascular supplements offer a range of complementary options.
Immune and respiratory function: Sunflower oil has traditionally been used to support the body's natural defences. It may help the body cope with seasonal respiratory challenges, including discomfort in the throat, sinuses, and airways.
Digestive comfort: The oil may also support digestive function, helping to ease occasional gastric discomfort and supporting overall gut wellbeing.
Brain and nervous system: Vitamin E and essential fatty acids are both recognised for their role in supporting cognitive function and the normal functioning of the nervous system.
Oral health: Sunflower oil has gained attention in natural wellness circles for oil pulling — a traditional practice of swishing oil in the mouth for 10–15 minutes. Advocates suggest this ritual may support oral hygiene and contribute to overall detoxification, although scientific evidence remains limited.
Sunflower Oil for Skin and Hair
One of the most popular external applications of sunflower oil is in natural skincare. Thanks to its high vitamin E content and emollient properties, the oil may support skin health in several ways:
- Deep hydration — sunflower oil helps lock in moisture without clogging pores, making it suitable even for oily or combination skin
- Skin barrier support — it may help strengthen the skin's natural protective layer
- Soothing irritation — traditionally used to calm sensitive, eczema-prone, or irritated skin
- Radiance — its nourishing properties may help give skin a healthier, more luminous appearance
Sunflower oil can also be applied to hair to add moisture and shine. For those seeking additional support from the inside, our hair, skin and nails supplements can complement a natural skincare routine.

The primary use of sunflower oil remains culinary. However, there is an important nuance that many people overlook: cold-pressed sunflower oil is best used unheated. When exposed to high temperatures, its polyunsaturated fatty acids can break down, potentially losing their beneficial properties and producing harmful compounds. For this reason, cold-pressed sunflower oil is best enjoyed as:
- A salad dressing — drizzled over fresh vegetables and greens
- A finishing oil — added to soups, grains, or pasta after cooking
- An ingredient in homemade mayonnaise or preserves
For daily supplementation, the recommended intake is approximately 2 teaspoons per day. For oil pulling, use 1–2 teaspoons and swish gently in the mouth for 10–15 minutes before spitting out.
[warning:Cold-pressed sunflower oil should not be used for frying or high-heat cooking. At elevated temperatures, its polyunsaturated fatty acids may degrade and produce potentially harmful compounds.]How to Choose and Store Sunflower Oil
To get the most out of sunflower oil, quality matters. When selecting a product, keep the following guidelines in mind:
- Freshness — check the production and expiry dates; fresher oil retains more active nutrients
- Cold-pressed — extracted at temperatures below 40°C, preserving delicate vitamins and fatty acids
- Unrefined — minimal processing ensures the oil keeps its full nutritional profile
- Dark glass bottle — protects the oil from light-induced degradation
Storage Tips
Cold-pressed sunflower oil should be stored in a cool, dark place at 5–10°C (such as a refrigerator). Under these conditions, it will remain usable for three to six months after opening. Refined sunflower oil is more shelf-stable and can be kept at room temperature in a kitchen cupboard, with a somewhat longer shelf life.

Sunflower oil deserves recognition beyond its role as a cooking ingredient. Its exceptional vitamin E content, beneficial fatty acid profile, and versatile applications — from salad dressings to skincare rituals to oil pulling — make it a genuinely multi-purpose natural product. Whether you are looking to support your skin, contribute to cardiovascular wellbeing, or simply enrich your diet with a quality cold-pressed oil, sunflower oil may be a valuable addition to your daily routine.

Key Takeaway: Sunflower oil is far more than a cooking staple — it is one of the richest natural sources of vitamin E and a versatile support for skin, heart, and immune health. Always choose cold-pressed, unrefined oil, use it unheated, and store it in the refrigerator for maximum benefit.
