Krill oil comes from krill, tiny shrimp-like creatures that live in very cold ocean waters. Studies show that krill oil might have health benefits similar to those of fish oil. Krill oil contains EPA and DHA, the same omega-3 fatty acids in fish oil, although usually in smaller amounts. The effects of krill oil have not been researched as thoroughly as those of fish oil. But a few preliminary studies suggest that krill oil could be superior in some ways.
A WBC count is a test that measures the number of white blood cells in your body. This test is often included with a complete blood count (CBC). Your blood contains a percentage of each type of white blood cell. Sometimes, however, your white blood cell count can fall or rise out of the healthy range.
An increased WBC count is an indicator of high levels of leukocytes in the blood, usually caused by an increased production of these cells in response to an infection or a medical condition. The upper normal limit for leukocytes in the blood is considered to be 11.000 leukocytes per micro-liter of blood. A count that is more than this is considered to be a high white blood cell count. This figure will vary in the case of children, depending on their age and body weight.
