Benefits of Fish Oil for Brain Health, Heart Health, and Inflammation

When people ask me which supplements they should take, of course, the answer is “it depends.”  It depends on their goals, their unique biochemistry, their lifestyle, their dietary intake, and so much more.  But there are three supplements that I recommend to almost everyone.  I’ve written before about the benefits of probiotics, and the benefits and types of magnesium, and today, it’s time for the third: here are the benefits of fish oil!

What are omega-3s?

First, let’s start with some important background information: the beneficial components in fish oil are the omega-3 fatty acids.  You may have heart of omega-3 fatty acids and omega-6 fatty acids, and you may have even heard that omega-6 are the “bad” kind.  This is not entirely true: we need both (as well as omega-9), but the average American gets far more omega-6 than they need, and not enough omega-3, so we are off balance.

Omega-6s come naturally from some foods like walnuts, tofu, and hemp seeds, as well as peanut butter, eggs, and almonds.  You may be thinking, “I don’t eat a ton of those, so why am I likely high in omega-6?” and the answer is that omega-6s also occur in high doses in processed and packaged food and low-quality oils.  This is the problem, and why we’re so off balance as a human population.  In fact, while the best ratio of omega 6 to omega 3 in our diets is likely between 1:1 and 4:1, some research shows that people who consume a Western diet may be closer to 15:1 to 17:1!  This is pretty dramatic and is the root of several health issues.

Benefits of Fish Oil for Brain Health, Heart Health, and Inflammation

What are the benefits of fish oil?

Fish oil supplements have been popularized (rightly so!) for their beneficial effects on heart health, brain health, and inflammation, and it’s all because of those omega-3s.

Here are some of the top benefits of fish oil:

How can I get omega-3s from food?

The three main omega-3 fatty acids are eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA).  EPA and DHA are found primarily in fish and other seafood, and ALA is found in a variety of plant-based sources.  When we consume ALA, our bodies can convert a small fraction of it into EPA and then DHA, but this process is very limited and would require a very large intake of ALA to get the DHA we need.  So, I recommend people consume a variety of the plant and animal foods required to get a balanced intake of omega-3s.

The best source of omega-3 fatty acids is fish.  If you don’t yet consume high-quality fish, I highly encourage you to do so, at least a few times per week!  Here are the omega-3 quantities of some of the best fish sources:

  • Mackerel: 4,850 mg omega-3 per serving
  • Salmon: 2,150 mg omega-3 per serving (I like the wild-caught salmon from Butcher Box – here’s a discount!)
  • Herring: 2,150 mg omega-3 per serving
  • Sardines: 1,463 mg omega-3 per serving
  • Caviar: 1,046 mg omega-3 per serving
  • Oysters: 329 mg omega-3 per serving

Given the caveat above, we are less likely to get the omega-3s we need from purely plant sources.  That said, here are some plant-based sources of omega-3s:

  • Chia seeds
  • Brussels sprouts
  • Hemp seeds
  • Flax seeds
  • Walnuts

What are the best fish oil supplements?

If you’re consuming multiple (3+) servings of high-quality fish like the above every week, you likely don’t need a fish oil supplement.  If you’re not, or you (like me!) want to be extra sure that you’re getting the benefits listed above, I recommend a fish oil supplement.

If you’re looking to include a fish oil supplement into your daily routine, here are things I suggest looking for:

  • At least 500 mg of combined EPA and DHA. Don’t look for total omega-3 content; as discussed, this includes ALA, which isn’t well-converted.
  • Practices to minimize the mercury content of the supplement and protect the environment (for example, Kion uses cold-pressed anchovies as a source to naturally minimize mercury, and Carlson uses deep, cold-water fish and sustainable sourcing practices)
  • An opaque bottle. Fish oil can be damaged by sun exposure, so we want the bottle to not be see-through
  • No other junky ingredients. There will almost always be other ingredients (for example, tocopherols can help with stabilization, and there needs to be a capsule surrounding the fish oil itself), but we want to minimize the chemical-sounding inactive ingredients on the label.

When to take fish oil: any time of day.  Ideally, with food, but this isn’t necessary.

Who should not take fish oil: If you’re taking blood thinners, talk to your doctor before taking fish oil.

My top fish oil recommendations:

  • Kion Fish Oil: Use code LYONS for a discount. I love that they include rosemary extract and astaxanthin to stabilize the oils and are using the right source of omega-3s for maximum absorption.
  • Carlson Elite Omega: My first recommendation before Kion came out with their product, it’s still a great option.
