Krill oil supplementation: big boost to HDL and lower LDL
Are your cholesterol levels worsening? Are you a candidate for statins and you'd prefer not to be? In that case, a human study that Canadian researchers published in Alternative Medicine Review a while ago suggests that krill oil is an interesting option. A hefty dose of the stuff can work wonders with your HDL, LDL and triglyceride levels.
One group was given a placebo daily; another group took 3 g fish oil daily. A third group took 1 or 1.5 g krill oil daily, and the fourth group took 2 or 3 g krill oil.
The researchers used krill oil produced by Neptune, a Canadian manufacturer. It is not entirely clear what Neptune's role in the study was.
The experiment lasted 90 days.
The HDL concentration increased by 4 percent in the fish oil users. Their LDL concentration decreased, but the effect was not statistically significant.
The daily dose of 1 or 1.5 g krill oil boosted the subjects' HDL by 44 percent and lowered their LDL by 32-35 percent. Their triglyceride concentration decreased by 11-12 percent, but the effect was not quite statistically significant.
The 2-3 g dose of krill oil had an even greater effect. That dose boosted the HDL level by 55-60 percent and reduced the LDL by 37-39 percent. The triglyceride concentration went down by 27-28 percent. All effects were statistically significant.
At the end of the 90 days the researchers got the subjects who had taken 1-1.5 g krill oil to take 0.5 g krill oil daily for another 90 days. This turned out to be an effective maintenance dose.
"The unique molecular composition of krill oil, which is rich in phospholipids, omega-3 fatty acids, and diverse antioxidants, surpasses the profile of fish oils and offers a superior approach toward the reduction of risk for cardiovascular disease."
