Fish Oil vs. Krill Oil: A Head-to-Head Nutritional Showdown

Ahoy, omega-3 enthusiasts! Today, we dive deep into the swirling waters of fish oil and krill oil to unravel their mysteries. Let the battle begin!

What's the difference between fish oil and krill oil?


Fish oil comes from—you guessed it—fish, while krill oil hails from those tiny, shrimp-like critters called krill. Both are rich in omega-3 fatty acids, but the key difference lies in their chemical structure. Krill oil's omega-3s are in phospholipid form, making them more easily absorbable by your cells.
