Wheat Germ Oil

Wheat Germ Oil: Nutrition and Guide

Wheat germ oil is extracted from the germ of wheat kernels (Triticum aestivum) — the nutrient-dense embryo that represents approximately 2.5% of the kernel and is separated during white flour milling. The germ is a concentrated source of nutrients — proteins, B vitamins, vitamin E, minerals — and the oil pressed from it is exceptionally rich in vitamin E, containing the highest natural concentration of this fat-soluble antioxidant vitamin of any food. A single tablespoon of wheat germ oil provides approximately 20 mg of vitamin E (primarily as alpha-tocopherol), more than meeting the adult daily requirement (15 mg). Wheat germ oil also provides a meaningful proportion of ALA omega-3 (approximately 6–7%) alongside linoleic acid and oleic acid. Due to its high polyunsaturated fat content, wheat germ oil is not suitable for cooking — it oxidises rapidly at temperature — and is used exclusively as a cold-pressed supplement and finishing oil.

Nutritional Value and Uses

Wheat germ oil provides 884 kcal and 100 g of fat per 100 g, with 18.8 g of saturated fat. The exceptional vitamin E content is its defining nutritional feature. Use a small amount (one teaspoon) stirred into smoothies, over cereal, mixed into salad dressings, or added to yogurt for a significant vitamin E boost and some ALA omega-3. Store in the refrigerator — the high PUFA content makes it extremely prone to rancidity — and use within four to six weeks of opening. Avoid if coeliac or severely wheat-gluten-sensitive (though most wheat germ oil contains negligible gluten, those with severe sensitivity should check with their medical team).
