published in the journal of the american college of nutrition. w, participants got 300 milligrams of neptune krill oil, the same krill that we use, or placebo. now, the folks on krill got some impressive joint comfort benefits. we're talking joint flexibility, joint functionality, joint comfort, all of them nicely supported. and, mark, we call this the krill-oil advantage. so, if you're just taking regular fish oil, well, that's great. i mean, fish oil's in here, but what this study shows us, mark, is that just a small does of krill can deliver some big-time joint benefits. on the other hand, if you're just using fish oil, you probably need to take a lot more of those really big capsules, right? and fish oil alone might take a little longer to kick in. >> that's really great news for all of us, especially for the over-50 crowd that might need that extra joint support. you know what else is great about this? lots of energy support. i love energy, so let's talk about the b12 energy melts for just a moment. you gave these away on our last krill show.
