Most olive oil on the market today is not truly 100% extra virgin. Kirkland guarantees their oils to be certified extra virgin and organic. You can tell the difference by it wonderful bouquet and the fabulous taste. No other oils I have purchased in this country can compare to Kirkland. It is well worth every penny you pay for this product. Try it and you will never go back to supermarket olive oil. Also, good olive oil is good for you, because it helps to lower the bad cholesterol and increase the good cholesterol in your blood. Kirkland certified organic extra virgin olive oil is my favorite. Also, try their certified extra virgin organic coconut oil, this is another product that good for you, can help with weight loss and it is the good cholesterol not the bad.
