In 2003, scientists at Newcastle University found that sage had a beneficial effect on memory. They used capsules that contained 50 microlitres of sage extract in sunflower oil. Have a look at the label on your capsules to get a dose similar to this. A few patients may develop raised blood pressure when taking sage, so if you have high blood pressure, avoid sage.
To answer this question properly, I bought a medium-sized (300g) grapefruit. I squeezed all the juice out of half of it, producing 70ml of juice. The original research into grapefruit juice and simvastatin looked at the effect of 200ml of grapefruit juice. The juice from half a grapefruit is about one-third of this amount. Even this amount will cause some people problems. The effect of each dose of grapefruit juice lasts for several days, so if you have half a grapefruit every morning the effect accumulates. My advice is to stick to oranges and orange juice if you are taking statins.
