I don't think it is special for lowering glucose, or blood pressure.
But it does help the lining of the blood vessels from getting clogged up or inflamed.

You'd need at least 3 a day, taken with a meal, in divided doses.
Krill oil also works well, and has less GI upset potential, and comes in smaller capsules. One double strength cap a day is enough for most situations. We are using the new Kirkland Krill that just appeared a couple of months ago (Costco). Costco has pretty good prices on MegaRed Krill too. Sometimes Amazon has good prices, but not always though.
