 It's omega-3s. That's the first most important nutrient you can take. And this krill omega-50 plus, I love the way they combine the krill oil with the fish oil so you can do the best of both worlds. Can't beat it. I've got to remind our listeners out there about this free bottle deal that's going on. The krill omega plus and the B12, it is a part of the special radio offer today. You just pay the shipping and you try it for free. And that number for those listening out there, write this down. It's 1-800-500-KRILL.
