Fish Oil or Krill Oil? What are the Differences?

Krill oil is extracted from small, shrimp-like crustacean zooplankton that inhabit the cold waters of the Antarctic Ocean. Antarctic krill is a vital component of the marine food chain. The catch and its processing are strictly regulated and carried out in an eco-friendly way, so as not to disturb the ecosystem and the environment. Antarctic krill are known for their rapid reproduction rates, and the catch amounts to only 1% of the total biomass. These factors make the extraction of pure Antarctic krill oil many times more ecological and environmentally friendly .

Krill oil has proven benefits for the human body with its rich composition of Omega-3 fatty acids, phospholipids and choline. The combination of these ingredients has a positive effect on the body, improving immunity, contributing to cardiovascular function, strengthening joints and speeding up metabolism. Krill oil is among the preferred nutritional supplements for strengthening the immune system .

Reduces signs of fatigue and exhaustion

Let's get into specifics. What specifically in this composition helps to improve the general physical condition and combat fatigue and exhaustion? It has been scientifically proven that the so-called vitamin B-complex or Vitamin B1, B2, B6, B12, D found in Krilixir Shield contribute to energy and the fight against fatigue . B1 (thiamine) is the vitamin that converts carbohydrates into energy. B2 (riboflavin) is essential for energy production and fat metabolism. B6 (pyridoxine) helps convert food into energy and supports the synthesis of neurotransmitters. And Vitamin A is important for the proper functioning of the immune system, helping to maintain the integrity of mucosal surfaces in the respiratory, gastrointestinal and urinary tracts, acting as a barrier against pathogens.

Acceleration of metabolism

Everything listed up to here also applies to the functions of the human body in metabolism. Vitamins D and B12, in addition to the above, have a beneficial effect on better general metabolism and the exchange of substances in the body . B12 (cobalamin) is necessary for the formation of red blood cells and energy metabolism. Vitamin D is what helps the body regulate the absorption of calcium and phosphorus, which is crucial for bone health and overall energy metabolism.

The effect on psychological function

Krilixir Shield, like the other Krilixir products , contains the best Omega-3 fatty acids, including EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These fatty acids are essential for brain health , and some studies suggest they may play a role in reducing symptoms of depression and anxiety (or so-called general psychological function).

"Shield" contains phospholipids , which are a type of fat that is a major component of cell membranes, including those in the brain. The presence of phospholipids can improve the absorption of Omega-3 fatty acids, potentially increasing their effectiveness.

Astaxanthin is a powerful antioxidant present in krill oil and has potential neuroprotective effects and fights oxidative stress. This is fundamental to positive mood and good cognitive function.

The food supplement supports the human body for the normal function of the immune system.
