Buying Guide: The Best Omega 3 Supplements

Omega-3 fatty acids are great for health. According to Dr. Dev Batra, owner of the Dallas Vein Institute, “A person who takes an Omega 3 supplement can expect to experience a number of health benefits. These benefits include a reduced risk of heart disease, stroke, and arthritis.”

Unfortunately, with so many brands offering different takes on this product, shopping for Omega-3 supplements can be a bit overwhelming. Don’t worry, though, because that’s where we come in. To make things a little easier, here’s a buying guide that goes over everything you’ll need to consider while shopping for an Omega-3 supplement.

What Are the Different Types of Omega-3 Supplements?

While there are many types of omega-3 supplements, we focused on two kinds:

  • Algal oil Omega-3 supplements
  • Fish oil Omega-3 supplements

The key difference between these lies in how their fatty acids are sourced. Let’s take an in-depth look at each type.

Algal oil Omega-3 supplements

If you’re looking for a vegan solution to your Omega-3 deficiencies, consider a formula made from algal oil. In these supplements, the fatty acids are squeezed from a type of marine algae which is rich in DHA.

Fish oil Omega-3 supplements

Unlike algal oil, fish oil Omega-3 supplements are naturally rich in both EPA and DHA. The fatty acids are sourced from fish, usually small ones such as mackerel and tuna. This is because small, deep-water fish usually aren’t subject to the same levels of pollution that other fish are. I get most of my Omega-3s from fish sources. If I were vegan, though, like some of our readers, I’d swap to the algal oil alternative.

Buying Tips

Here are two tips to ensure you get a good deal when in the market for a new Omega-3 supplement:

Potency

The supplement’s potency will dictate the amount of omega-3 present in it. The tip here is to go for a good balance between eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The exact potency of each Omega-3 you’ll require will depend on the severity of your deficiency. We recommend consulting your physician to figure out a daily recommended dosage for yourself. I managed to increase my Omega-3 consumption when I moved closer to the ocean and ate more fish. Before then, I was lower in Omega-3s. The point of the story, your diet will dictate your potential deficiency.

Serving size

Your daily dosage of Omega-3 will also determine how many pills you’ll need to take each day. If you’re just starting out, it’s a good idea to buy a supply that will last you at least a couple of months. You can always get more to stock up, but just make sure that the supplements have an adequate shelf life.

Price Range of Omega-3 Supplements

As far as dollar signs go, you can expect to shell out anywhere from $0.10 to upwards of $0.50 per serving when in the market for a new Omega-3 supplement. Things like potency level, brand name, third-party certifications, and ingredient quality will contribute to inflating this price tag, which, on the whole, can cost you anywhere from $20 to $40 or more per bottle.

How We Shortlisted Our Top Omega-3 Supplements

We closely evaluated the following factors when selecting the products on this list.

Dosage form

As far as ingestion goes, we only went with Omega-3 supplements that come in a soft gel form. The gelatin lining on these ensures that you won’t have to deal with a fishy taste or smell, and it also helps prevent annoying fish burps.

Flavor

We also made sure to include both flavored and unflavored Omega-3 supplements in our list. This ensures variety so that you can choose one that suits your preferences.

People Also Asked

Do omega-3 supplements have side effects?

The exact side effects of your new supplement (if any) will vary from product to product. Generally, though, you could expect mild headaches, heartburn, and nausea when you initially add these supplements to your diet if you are sensitive to those issues.

What are omega-3 supplements good for?

You can expect lower levels of triglycerides when incorporating omega-3 supplements into your diet. These fatty acids also boost your overall heart health, making them beneficial in more ways than one.

Can I take omega-3 supplements without consulting a doctor?

You should always consult your physician before adding a new supplement to your diet. Not only will they steer you clear of ones you might be allergic to, but they'll also guide you toward options more suited to your condition.

Is it good to take omega-3 supplements everyday?

Yes, as they can help you get your daily dose of omega-3 fatty acids. If you're inconsistent, you won't be getting the most out of what they can offer.

How long does it take for omega-3 supplements to work?

Omega-3 supplements can take some time before they start to show results. Usually, though, you should be able to notice some sort of change after around six weeks. If you don't, consider asking your doctor why this may be.
