An exploration of krill marine phospholipids

New book on the power and potential of krill oil for human health

Lena Burri, Ph.D. and research Director in Aker BioMarine, has spent much of her career researching and exploring the health effects of krill phospholipids. She brings this knowledge together in her latest book, which educates the reader on how nutrient-rich Antarctic krill can help bridge common nutritional deficiencies.

 

What makes krill oil a unique nutritional supplement?

 

That’s the very question that Burri dives into in her book, titled “An exploration of krill marine phospholipids”. In it she offers a thorough overview of all the naturally occurring, distinguishing qualities of this tiny Antarctic crustacean.

 

New call-to-action

Through years of study, Antarctic krill has emerged as an important source of essential nutrients, such as long-chain omega-3 fatty acids, phospholipids, and choline – key to health across species. These components play an important role in cell organization and function, which lead to meaningful health improvements.

Here’s a glimpse at what you’ll find inside Burri’s new book.

 

Top 5 highlights from “An exploration of krill marine phospholipids” by Lena Burri:

 

  1. Krill is one of the most abundant species on Earth with one of the largest biomasses.

There’s certainly no shortage of krill. Antarctic krill gathers in large swarms and has the most potent known digestive enzymes on Earth. They feed on microscopic, free-floating algae, which means that krill accumulates important nutrients through their diet.

 

Krill is caught exclusively in area 48 off the Antarctic peninsula, with highly precautionary catch limits set to 1% of the total estimated biomass in that area to support the sustainability of the industry.

 

  1. What really differentiates krill oil is essential nutrients delivered in a unique molecular form.

In krill oil, the omega-3 fatty acids are bound to phospholipids. And there is strong scientific evidence that this difference is important. Phospholipids are a natural part of the cell membrane, which means this delivery form of the omega 3 supports better integration with bodily tissue. As a result, more omega-3 is transported, absorbed and utilized in the body when it comes from krill.

 

  1. We need a solid balance of omega-3 and omega-6 fatty acids in our diet

Our modern, western diets feature an abundance of omega-6 fatty acids, creating an imbalance that can lead to health issues. Since most people do not consume enough fish during the week to achieve the recommended amount of omega-3 fatty acids, supplements have become essential to help us keep the body’s inflammatory response in check, thus supporting better heart and cognitive health, for example.

 

  1. Krill is also a natural source of choline, with is crucial for normal cellular function.

Choline is an essential B vitamin-like nutrient that supports better cellular health. Insufficient levels of choline in the body may lead to fatty liver, muscle damage, and increased risk of neural tube defects.

 

Around 90% of the U.S. population is not consuming enough choline to ensure optimal cell membrane function, writes Burri, which means that humans require supplementation to bridge this deficiency. There is evidence that choline supplementation can support memory, cardiovascular health, and reduce inflammatory markers.

 

  1. Documented health effects of krill oil

Krill oil, as a source of essential nutrients for humans, has been the subject of numerous studies over the years. There is evidence that krill oil promotes cellular and organ health in both animals and humans, related to various conditions.

 

Burri writes that krill oil has been shown to improve cardiovascular risks in individuals with type 2 diabetes, as one example. Krill has also been demonstrated to have positive effects on liver health in animals. And it’s been known to support improved brain, eye, and skin health, as well as aiding the pain reduction in patients with osteoarthritis of the knee. Studies have also been conducted on krill’s impact on sports performance, where it’s been shown to improve recovery and support immune levels in athletes.
