Can Krill Oil Protect Your Brain?


Krill oil comes from the family of marine oils. However, it’s less popular than other oils like omega fatty acids, but recently, scientists have begun to study krill oil. Krill oil contains a high concentration of antioxidants, long-chain omega-3 fatty acids, and choline. Choline is a vital ingredient that contributes to the formation and operation of a healthy brain.


In addition, krill oil was shown to slow memory decline in an Alzheimer’s test carried out on an animal model. An analysis also found that krill oil’s lipid structure makes it more bioavailable and efficient at being absorbed, making it more helpful for inflammation and brain health than other marine oils.

What Are the Benefits of Krill Oil

Another perk is that choline can be found in krill oil. Due to its role as a precursor to the neurotransmitter acetylcholine, choline is essential for a wide range of brain activities, including memory formation, mood regulation, and muscular control.


In addition, krill oil is helpful since it contains antioxidants such as astaxanthin. Possible advantages of astaxanthin include its ability to combat diabetes, improve cardiovascular health, safeguard the nervous system, and safeguard eye health.


It also has the potential to raise HDL, also known as “good” cholesterol. Previous studies support this idea. One to three grams of krill oil per day increased HDL (“good”) cholesterol and decreased LDL (“bad”) cholesterol, blood glucose, and triglycerides in a randomized controlled trial.

Can Krill Oil Help with Alzheimer’s or Parkinson’s

Researchers show that krill oil is a promising agent for promoting healthy aging in several ways, making it a good choice for future preclinical and clinical studies.


Moreover, signs of neurodegenerative diseases like Parkinson’s and Alzheimer’s typically don’t appear until the later stages of the disease’s progression. For instance, the onset of motor symptoms in PD does not occur until more than 80% of DA neurons have died. 


Thus, people at higher risk of acquiring neurodegenerative disorders would benefit greatly from implementing any remedy that would slow down the development of neurodegeneration. The findings of this study are encouraging because they point to a change in diet that may prevent the deterioration of DA neurons as people get older.

What Are the Limitations of Krill Oil

When used properly and for a limited time, krill oil may be safe for most individuals. However, no studies have looked into the potential dangers of krill oil. On the other hand, like fish oil, krill oil may result in gastrointestinal distress, a fishy aftertaste, a sour stomach, a feeling of being sick, and loose stools.
