What is omega-3 and why should a person eat omega-3 as dietary supplements?
Omega-3 is a group of essential polyunsaturated fatty acids (PUFAs), which means they are fundamental for human health. They play important roles in the body as components of the structures of cell membranes, act as important signaling molecules and provide a significant anti-inflammatory contribution. Omega-3 is also known to support heart-, brain- and eye health.
The human body do not have the ability to make omega-3s and we have to obtain them through the diet. Consuming omega-3 directly from foods or dietary supplements is the only practical way to increase levels of these important fatty acids in the body.
Omega-3 intake is notably low worldwide, and this is a major public health issue. In the U.S. 95+% of Americans do not get enough EPA and DHA to be cardioprotective. Consequently, most people would benefit from taking an omega-3 supplement.
Calanus® Oil gives additional benefits by supporting insulin sensitivity, thereby optimizing metabolism of sugar and fat.
What is EPA and DHA?
EPA and DHA are long-chain omega-3s that come primarily from marine (sea) sources. They are originally synthesized by microalgae, not by the fish. When fish consume zooplankton (such as Calanus finmarchicus) that consumed microalgae, they accumulate the omega-3s in their tissues. In nature there are no good terrestrial sources for these long-chain omega-3, plants and plant oils contain only a shorter omega-3, which the human body cannot utilize as efficient and beneficial as the long-chain omega-3s.
Calanus® Oil is the only ingredient that contains SDA in addtion to EPA and DHA.
What is stearidonic acid (SDA)?
SDA is an omega-3 fatty acid that can be converted to EPA in the body. SDA also serves as a powerful activator of intestinal receptors that regulates the body´s handling of sugar, fat and inflammation processes. Calanus® Oil is the only commercially available marine source of SDA.
What is wax ester?
Wax ester is the natural molecular form of omega-3 in Calanus® Oil. A wax ester is digested more slowly than other omega-3 molecules (like triglycerides from fish oil and phospholipids from krill oil) and will therefore reach, and activate, important receptors in the distal intestine. These receptors regulate sugar- and fat handling as well as several inflammation processes in the body. Wax esters are considered to be very potent omega-3 molecules.
What is a lipid?
A lipid is a fat molecule found in living things. Fats are made from lipid molecules. Lipids are long chains of carbon and hydrogen atoms, and their main functions are to serve as building blocks for cell membranes and as energy reserves.
How is Calanus® Oil different from krill oil or fish oil?
Calanus® Oil differs from fish and krill oils in several ways. Because Calanus® Oil comes from a naturally pure raw material, the oil is low-processed and unrefined. This gives a nutritionally complete oil containing a broad range of nutrients, like for instance stearidonic acid, SDA, and very high natural levels of the potent antioxidant astaxanthin. The wax ester form gives a slow digestion, whereas fish- and krill oil has a very rapid uptake. The PUFA- activated receptors are located deep down in the intestinal system, and only Calanus® Oil will reach them in relevant amounts. This means that in addition to offering the traditional omega-3 benefits, Calanus® Oil supports healthy insulin handling and reduced deposition of intra-abdominal fat.
What kind of future health problems could be solved by Calanus® Oil?
Calanus® Oil has been shown to increase insulin sensitivity in humans. Loss of insulin sensitivity is a key factor in development of type 2 diabetes (T2D). Calanus® Oil has the potential to help preventing the development of T2D. According to WHO, more than 420 million people have diabetes, and this number is expected to double in the next 20 years.
In media, there is a debate about omega-3 vs. omega-6. What is the issue?
The western diet contains too much omega-6 relative to omega-3. Omega-3 decreases inflammation, whereas omega-6 increases inflammation. Generally, the omega-6 content is high in animalic fats and vegetable oils. Therefore, higher intake of omega-3 from marine sources is needed to reduce the inflammatory state of the body, thereby reducing long term risk factors for cardiovascular disease and other metabolic disorders.
