Hey folks! Max Cage here, your friendly neighborhood pharmacist. Now, if you’ve ever wandered down the supplement aisle, you’ve probably been bombarded by an ocean of options for getting your omega-3s.

The Basics: What Are They?

Before we dive into the differences, let’s get a quick refresher on what these oils are:

  1. Fish Oil: Extracted from fatty fish like salmon, mackerel, and sardines. It’s rich in two types of omega-3s – EPA and DHA.
  2. Krill Oil: This one’s derived from tiny shrimp-like creatures called krill. Along with EPA and DHA, it contains a pink-hued antioxidant called astaxanthin.

The Omega-3 Showdown

Now, for the heart (and brain and joints) of the matter. Let’s break down how these oils stack up against each other:


  • Krill Oil: Here’s where krill oil has a slight edge. It contains omega-3s in a phospholipid form, which might be easier for our bodies to use than the triglyceride form in fish oil.
  • Fish Oil: Still a fantastic source of omega-3s, but it may not be as efficiently absorbed as its krill counterpart.


  • Krill Oil: Remember astaxanthin I mentioned earlier? This antioxidant not only gives krill oil its distinctive red tint but also helps protect the body from free radicals.
  • Fish Oil: While fish oil does have some antioxidant properties, it doesn’t contain astaxanthin.


  • Krill Oil: Krill are at the bottom of the marine food chain, and there are concerns about overharvesting affecting marine ecosystems. However, some brands source sustainably.
  • Fish Oil: Many brands use fish that are more abundant, making it a more sustainable choice. Always check for certifications on the label.


  • Krill Oil: Many users report fewer fishy burps and aftertaste. A win for those with sensitive taste buds!
  • Fish Oil: It can sometimes leave a fishy aftertaste, but many brands now offer flavored or enteric-coated options to combat this.

Price Point

  • Krill Oil: Generally, krill oil tends to be pricier than fish oil, given the additional benefits and the cost of sustainable sourcing.
  • Fish Oil: More widely available and tends to be more wallet-friendly. It’s a good option for those on a budget.

Potential Benefits

Both oils offer a boatload of benefits, thanks to their omega-3 content:

  • Heart Health: Omega-3s are champions for the heart, potentially reducing bad cholesterol and increasing the good.
  • Brain Boost: These fatty acids are essential for brain health, possibly improving memory and cognitive functions.
  • Joint Joy: Omega-3s can help reduce inflammation, providing relief for achy joints.
  • Mood Modulator: There’s promising research suggesting omega-3s can help with mood disorders.

Max’s Parting Thoughts

Alright, ocean explorers, we’ve navigated the seas of krill oil and fish oil. So, which one’s the catch for you? Well, it comes down to personal preference, budget, and individual health goals. Both are fantastic ways to get those crucial omega-3s.
