The fat intake enough omega-3 health is key to good health. An excellent source is wild salmon or Alaska red salmon, but choice lesser known is krill oil. This supplement is extracted from small shrimp-like crustaceans found in the crystal clear waters of Antarctica. Krill oil is actually almost 48 times more potent than fish oil.
Krill offers benefits both in terms of personal health, and environmental impact. It is highly sustainable because of their huge biomass of 170 million tons to 740 million of which we are currently harvesting only about two percent. Unlike fish, krill is at the bottom of the food chain, so no heavy metals and other contaminants accumulate.
A recent study shows that krill oil is superior to fish oil in terms of genes that influence. The omega-3 fats control “switches” that turn genes on and off, directing the metabolic processes of the production of glucose, lipid synthesis, cellular energy, oxidation and others. Unlike fish oil, krill oil improves glucose metabolism in the liver, helps the lipid metabolism, regulates the mitochondrial respiratory chain, and reduces cholesterol synthesis.
The net effect is that the krill decreases levels of triglycerides and cholesterol and increases energy production, while fish can even increase cholesterol, according to the latest research.
Previous studies show krill can lower blood glucose, which has important potential benefits for people suffering from diabetes and obesity. Fish oil is also prone to oxidation, while astaxanthin present in krill oil stabilizes and makes it oxidation resistant.
Indeed, astaxanthin is superior many other antioxidants. It is 6,000 times stronger than vitamin C, 800 times stronger than CoQ10, 550 times stronger than green tea catechins, and 75 times stronger than alpha lipoic acid. In human studies, it was demonstrated that astaxanthin to reduce oxidative stress and inflammation (source) Finally, unlike fish oil, krill is not contaminated by mercury and other heavy metal contaminants.
