The richest plant source of omega-3
Bulk flaxseed oil, also called linseed oil, is pressed from the seeds of the flax plant. More than half of its fatty acids are alpha-linolenic acid (ALA), the plant omega-3, which makes it the richest common plant source of omega-3. That is why food-grade flaxseed oil is used in supplements, health foods, smoothies, dressings and functional products, and why it is eaten raw rather than heated.
Our flaxseed oil is cold-pressed, tested and packed in the United States from US-grown and imported flaxseed, and supplied from 1-liter bottles to 20,000-liter flexitanks.
Food-grade flaxseed oil only
We supply one grade: cold-pressed, food-grade flaxseed oil. It is not the same as the linseed oil sold for wood finishing and paint. Industrial “raw” and “boiled” linseed oils are made for drying and can contain metal driers and other additives; they are not food. Food-grade flaxseed oil is pressed from clean, food-quality seed and packed in food-grade containers.
Freshness is everything
- Very high in ALA. Western Canadian flaxseed, for example, has averaged about 54–59% ALA in its oil year to year.
- Oxidizes quickly. All that omega-3 makes the oil sensitive to air, light and heat, which create bitter, fishy off-flavors.
- Packed to protect it. We press in small runs, fill containers full and sealed, and recommend nitrogen-flushed drums and dark bottles.
- Cold storage. Keep it cold and dark from delivery onward, ideally refrigerated, and never use it for frying.
How bulk flaxseed oil is priced
Flaxseed oil prices follow the flax harvest, and short shelf life means it is pressed to order rather than stored. Each quote is based on pack size, total volume and destination; the minimum is 1,000 liters per quote.

Sourcing
From flax fields to finished oil
Flax is a cool-climate crop grown on the northern US plains and in other temperate regions. Our flaxseed oil is cold-pressed, tested and packed in the United States from US-grown and imported food-quality flaxseed.
The seed is cleaned, pressed without added heat or solvents, settled and filtered, then filled straight into full, sealed containers to protect its omega-3. Every batch is tested before it ships.

FAQ
Linseed Oil questions
What is the minimum order?
1,000 liters (about 264 US gallons) per quote, across any combination of oils, grades and pack sizes. For example, one 1,000L IBC tote, five 200L drums, or 50 cases of 4 × 5L bottles.
Is linseed oil the same as flaxseed oil?
They come from the same plant. In food, the oil is usually called flaxseed oil; “linseed oil” also describes industrial oils for wood and paint, which are not food. We supply only food-grade, cold-pressed oil.
How much omega-3 does flaxseed oil contain?
Typically more than half of its fatty acids are alpha-linolenic acid, a plant omega-3. Each lot’s ALA content is on the Certificate of Analysis.
Can flaxseed oil be used for cooking?
No. Heat damages its omega-3 and creates off-flavors. Use it raw in dressings, smoothies and dips, or add it after cooking.
How should flaxseed oil be stored?
Cold, dark and sealed, ideally refrigerated, and used within a few weeks of opening.
How is the price set?
Each grade is priced separately, based on the crop, grade, pack size, total volume and delivery destination. Your quotation shows the price, any freight and other charges, the shipping terms and route, and an estimated arrival date.
