Is Krill Oil Astaxanthin? A Detailed Explanation of the Differences Between Krill Oil and Astaxanthin!

Actually, there are many products containing astaxanthin on the market today. Among so many products, many people find it difficult to distinguish which ones contain real astaxanthin. Moreover, a large number of people confuse krill oil with astaxanthin, thinking they are the same thing. So today, Xiao Ai will explain the differences between Antarctic krill oil and astaxanthin.

Different Sources, Different Astaxanthin Content

Krill oil is mainly extracted from Antarctic krill, which feeds on algae, so the extracted krill oil contains a small amount of astaxanthin. One capsule of krill oil contains only 6-30 micrograms of astaxanthin (1 microgram = 0.001 milligram), which is almost negligible. Based on the highest astaxanthin content of 30 micrograms, you would need to take about 100 capsules of Antarctic krill oil to obtain 3mg of astaxanthin. Obtaining astaxanthin by taking krill oil is obviously unrealistic. Natural astaxanthin, on the other hand, is mainly extracted from Haematococcus pluvialis. Haematococcus pluvialis is the "concentrate" of astaxanthin in nature and the substance with the highest astaxanthin content, reaching 3%-5% of dry weight. Moreover, the astaxanthin in Haematococcus pluvialis has a left-handed structure, which is more favored by cells and better absorbed by the human body, making it highly bioavailable. Compared to krill oil, astaxanthin from Haematococcus pluvialis has higher content and is more natural.

Different Ingredients, Different Effects

Krill oil contains many ingredients, mainly fatty acids: Omega-3, phospholipids, and astaxanthin, but the astaxanthin content is very low. The main effects of krill oil come from fatty acids, which can improve blood lipids, help maintain cardiovascular and cerebrovascular health, prevent cardiovascular and cerebrovascular diseases, and have a protective effect on the heart.

Consumers see merchants promoting many benefits of krill oil, such as anti-aging, immune enhancement, eye protection, and joint discomfort improvement. In fact, these are not the effects of krill oil, but of astaxanthin. Many merchants sell krill oil under the banner of astaxanthin, which is purely misleading!

The astaxanthin in Haematococcus pluvialis, after wall-breaking extraction, is very pure and contains no other ingredients. Natural astaxanthin, due to its powerful antioxidant properties, unique structure, and penetrability, has multiple health benefits. In recent years, with rapid technological advancements, more and more powerful functions of astaxanthin have been discovered and verified, making astaxanthin extremely popular. This is something Antarctic krill oil cannot compare with.

Different Safety Profiles

Krill oil comes from krill, which is seafood and contains certain allergenic proteins. For people with allergies, it can easily cause skin itching, redness, swelling, rashes, and other symptoms. Natural astaxanthin comes from Haematococcus pluvialis, which is a plant and contains no allergenic proteins, so it does not cause allergies and has relatively higher safety. At the same time, Haematococcus pluvialis astaxanthin is a "new resource food" approved by the National Health Commission of China, with higher safety standards.
