Grapeseed oil is a polyunsaturated fat pressed from grape seeds. Linoleic acid, an omega‑6 fatty acid, makes up most of its fat content and forms part of cell membranes. The oil also supplies a small amount of vitamin E.
Cooks use it for everyday cooking or as a dietary oil. Some people take it by the teaspoon for the linoleic acid. Linoleic acid helps maintain the skin barrier. Swapping saturated fats for grapeseed oil can support healthy cholesterol levels.
No standard supplement dose exists. The oil fits easily into meals or is taken plain, usually in small amounts.
Grapeseed oil is rich in omega‑6. Pairing it with omega‑3 sources such as fish oil or flaxseed helps keep a balanced fatty acid profile. Anyone with a grape allergy should avoid it. The modest vitamin E content could, in theory, add to bleeding risk for people on blood-thinning or antiplatelet drugs. Check with a healthcare provider.
