Krill Oils Vital Lipids Offer A Range of BenefitsKrill oil is sometimes compared to fish oil as an omega-3 dietary supplement. But authentic krill oil complex contains a greater range of nutrients, and its benefits far exceed those of fish oils. Most of the DHA and EPA of krill oil occurs linked into larger phospholipid molecules (pronounced fos-fo-lip-ids). These are preformed building blocks for the cell membranes that drive life processes. In fish oil, by contrast, all the DHA and EPA occurs as triglycerides, which are storage forms of fatty acids (fat). The DHA and EPA has to be removed from the triglycerides, then linked into phospholipids prior to inserting them into cell membranes.Krill oil gets its red color from astaxanthin, a carotenoid nutrient. Astaxanthin is a potent membrane antioxidant and helps ensure krill oils exceptional shelf life stability. Fish oils lack astaxanthin and are vulnerable to premature rancidityoxidative degradation of the fragile DHA and EPA molecules. Krills phospholipids, DHA, EPA, astaxanthinall can be readily inserted into cell membranes.Krill oil has produced impressive benefits in clinical trials, superior when compared against fish oil.Superior to Fish Oil for Premenstrual ChallengesIn a large proportion of women, premenstrual problems affect life quality by negatively affecting mood and other mental state and by generating pain and other physical problems. In a double blind trial, krill oil was compared against fish oil for the relief of ten well recognized premenstrual complaints.4Seventy (70) women of childbearing age consumed 2 grams of either a krill oil or a fish oil, daily for the first month. Then for the next 2 months, they took the assigned supplements for just eight days prior to menstruation and another 2 days subsequent. They filled in detailed questionnaires and kept track of their daily analgesic (painkiller) medication use.
