Benefits of Krill Oil For Fat Metabolism
Your cholesterol levels may drop by a whopping 33 percent and you may also see improvements in liver triglyceride levels, which is superior to fish oil according to data from this short-term study.
More research is always being conducted to confirm and validate the existing research on krill oil. This is common because the more studies that are conducted that duplicate results, the more valid the data becomes.
This study was a short-term study that was conducted with rats, but it falls in line with another study that was conducted with humans suffering from metabolic symptoms often seen in people with higher fat levels in the heart and liver (obese individuals).
The participants in this study supplemented their diets with 2.5% krill oil or 2.5% fish oil, and the results were a 33% reduction in cholesterol for the krill oil consumers, and a 21% reduction in cholesterol levels for the fish oil consumers.
The participant’s liver triglyceride levels are dropping by 20 percent while using krill oil and just 10 percent for those using fish oil.
The researchers from the University of Salento strongly believe that this creates new opportunities for krill oil supplementation as a tool for preventing high cholesterol and blood fat levels (often called dyslipidemia).
This could point other research in the right direction in order to confirm this data as accurate.
The results of this study showed that the enzymes in the liver that are involved in the metabolism of fat were significantly inhibited by both fish oil and krill oil; though the effect was much larger for krill oil after two or three weeks.
The researchers suggested a higher potency of krill oil could lead to decreases in hepatic lipogenesis compared to fish oil during short two- to three-week periods. Also, they believe that by preventing lipogenesis (which was observed in krill oil-fed animals) was most likely due in part to the decrease in liver concentration of both triglycerides and cholesterol.
Even though this study was conducted with animals, it is very encouraging and it is in line with the findings of a human trial studying the effects that krill oil may have in preventing metabolic symptoms in obese individuals. These types of studies allow researchers to continue looking deeper even at a much deeper level (the mitochondrial level).
