Ostro Organics Oils are pressed fresh, in small batches in Victoria B.C.

Crop origin

The origin of the various crops are subject to change, due to harvest short falls, cost of shipping and world demand. Especially with nuts coming from overseas, special focus on unpasteurized nuts, the country of origin changes frequently.

Production steps

  • The raw oil is being pressed in small batches.
  • After pressing the oil sludge settles to the bottom of the oil barrel.
  • The fresh oil is then carefully being decanted and bottled.
  • Followed by capping and proper labeling.

Cold Pressing Technique

At Ostro Organics we use a modern low-pressure screw press to extract the oil from the nuts and seeds. Focusing on low pressure and low heat extraction. Higher heat means higher yield but also more alteration when it comes to its molecular structure. At Ostro Organics, we press every oil at a different heat point. Ranging from 9° to 29° degrees Celsius.

Ostro Organics presses oils under very low pressure and minimal temperatures. Currently ranging between 9° and 29° Celsius. Resulting in low yield oil extraction, obtaining a yield of roughly 55% depending on the variety of nut and seed.

Higher yields can be easily reached by applying industry standards including more pressure, heat, solvents and adding other agents to the extraction process.

When consuming Ostro Organics walnut oil in this pure, fresh, natural and real form, you will NOT be consuming hydrogenated fats or trans fatty acids.


Refrigerate after receiving and opening.

When storing outside the fridge, keep away from direct sunlight and heat sources!

Adding walnut oil to your diet may fight chronic inflammation, which has been linked to heart disease, some cancers, and other health issues (Trusted Source).

One 6-week study in 23 adults with high cholesterol found that a diet high in ALA, one of the main fatty acids in walnut oil, decreased the production of inflammatory proteins in the body (Trusted Source).

Walnuts are also rich in polyphenols called ellagitannins, which your gut bacteria convert into other beneficial compounds (Trusted Source).

These compounds may have anti-inflammatory properties and act as antioxidants that fight cell damage caused by molecules called free radicals. This may explain why test-tube studies have found that walnut oil can fight inflammation and increase cell antioxidant activity (Trusted Source, Trusted Source).

However, it’s unclear to what extent the beneficial compounds in walnuts are preserved during the processing of walnut oil. Some studies suggest that walnut oil contributes no more than 5% of the antioxidant activity of whole walnuts (Trusted Source).

Thus, more research on the anti-inflammatory effects of walnut oil is needed.

Fresh Walnut oil is hard to find but can be used in many ways.

It typically has a light color and delicate, nutty taste. The most high-quality walnut oils are cold-pressed and unrefined, as processing and heat will destroy most nutrients and lead to a bitter taste.

It’s not recommended to use walnut oil for stir-fries or high-heat cooking. Additionally, most walnut oils can only be kept for 2–4 months in a cool, dry place after being opened before going rancid.

The most common use for walnut oil is as an ingredient in salad dressings with vinegar and mayonnaise. It also tastes delicious drizzled over steamed vegetables.

You can find fresh Ostro Organics walnut oil at specialty health food and specialty grocery stores, as well as online. It’s typically more expensive than other oils as walnuts are in very high demand and therefor very expensive to source.


Cold-pressed, unrefined walnut oil has a delicious, nutty taste. It’s primarily used in salad dressings and other cold dishes.

Walnut oil may help lower high blood pressure, one of the main risk factors for heart disease (Trusted Source).

Studies suggest that diets rich in whole walnuts can help lower blood pressure, likely because of their high levels of ALA, LA, and polyphenols. Given that walnut oil is also rich in these compounds, it may exert similar effects (Trusted Source, Trusted Source, Trusted Source).

One study in 15 adults with overweight or obesity and moderately high cholesterol levels found that consuming walnut oil significantly improved blood vessel function, which in turn could help lower blood pressure (Trusted Source).

However, more studies on walnut oil’s potential effects on blood pressure are needed.

Studies suggest that consuming walnuts and walnut oil may improve blood vessel function and lead to lower blood pressure.

Can boost skin health

The nutrients in walnut oil may promote good skin health.

One tablespoon (13.6 grams) of walnut oil contains more than 8 grams, or over 5 times the Dietary Reference Intake (DRI), of an omega-3 fatty acid called alpha-linolenic acid (ALA) (Trusted Source, Fatty Acids Source).

In your body, some ALA is converted into the longer forms of omega-3 fatty acids called eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which help form the structural components of your skin (Trusted Source).

That’s why omega-3s, including those in walnut oil, may stimulate skin growth, fight inflammatory skin disorders, and promote wound healing (Trusted Source).

What’s more, walnut oil contains high amounts of the omega-6 fatty acid linoleic acid (LA), the most predominant fatty acid in the outermost layer of your skin (Trusted Source).

In short, consuming walnut oil boosts your intake of essential fatty acids that are vital to skin health.

Walnut oil is a delicious, nutty oil made by pressing whole walnuts.

It’s rich in the omega-3 fatty acid ALA and other unsaturated fatty acids, as well as ellagitannins and other polyphenol compounds that act as antioxidants.

Thus, consuming walnut oil may improve blood sugar levels and boost heart health, among several other benefits. Yet, more research is needed.

To reap the possible benefits of walnut oil, try using it in salad dressings and other cold dishes.
