Some articles liked the idea of extracts rather than the leaf, while others liked the combined approach, and advised to take a strong extract together with the ground leaf.

Seagate discounts the whole idea of standardizing for oleuropein, and instead doesn't try to optimize or exclude anything in the olive leaf, but to concentrate everything there.
I guess I should try the Seagate and see how it compares with other brands.

Some articles say to take olive leaf with food. Some say to take it on an empty stomach, and some say it can be taken either way. I guess arguments can be made for each, but which is better? Perhaps taking it around 20 minutes before a meal might be best?

The one thing I noticed was that the Olympian brand of olive leaf extract was so much more fragrant than the other brands I used. I didn't even open the capsule. Just opening the bottle gave a strong fragrence. With the other brand I still have I could not really smell anything with my nose next to the open bottle.
