Fish Oil vs. Cod Liver Oil – What’s the Difference?

You may have seen supplements of cod liver oil and fish oils and thought they are same. But to your surprise, these oils are different because their sources are not same. 

Yes, they have similarities, like both of these oils are rich in omega 3. Seems interesting? Let’s explore more about their main differences. 

Sources of Fish Oil and Cod Liver Oil

You can get fish oil from any kind of fatty fish. Have you ever heard about the cod fish? Yes, liver of cod fish is the only source of cod liver oil. You can extract it from Pacific cod and Atlantic cod. You can use it in dietary supplements as a rich source of omega 3s as well as fat soluble vitamins (A and D). These micro-nutrients work wonders for immune support, bone health, or prenatal care. Hence, it suits supplements catering to vitamin deficiencies.

Both of the oils are loaded with omega 3. If you have a nutraceutical brand, you can use fish oil when manufacturing omega-3 softgel capsules. Another reason for their popularity is, you can store these capsules easily and even ship them all over the world. 

So if you can not eat fish regularly, you should take supplements of cod liver oil and fish oil. 

But like everything, cod liver oil has some downsides. It comes with many manufacturing challenges. Being heat resistant, it needs consistent refrigeration. 

In addition to this, you can safely use only a small amount of cod liver oil per softgel. That’s because it’s ingredients can lead to severe side effects if you take higher dose accidentally.

Key Differences Between Fish Oil and Cod Liver Oil

Nutrient Composition

As you know, both these oils are rich sources of omega 3 and provide heart friendly fatty acids, EPA and DHA. But cod liver oil is comparatively more nutritious as it also includes vitamin A and D.

This is great if you want a multitasking supplement. You can make a product that works for immunity as well as bone health. 

Although it is beneficial in minor amounts, vitamin A can cause toxicity if overdosed. This risk limits how much cod liver oil you can add to your supplement.

With fish oil, you get much more formulation flexibility. As there’s no vitamin naturally present, you need not worry about touching the upper safe limits for micronutrients.

Making fish oil based pills is just like working on a clean slate. You can design your customized formula and add ingredients accordingly.

Source and Raw Material

You can get fish oil from multiple fish species, from different body parts (skin and flesh). Due to convenient sourcing, fish is easily available and costs much less than cod liver oil. 

On the other hand, fish oil is expensive. The liver tissues are storage houses for fat soluble vitamins, which are drained into the oil.

Cod Liver Oil Benefits 

It is good for people who have deficiency of vitamins D and A. You can use it to calm inflammation and support your immune system and bone health. Thus, it is a solid pick if you’re creating a multi-benefit supplement. Here’s what it can do:

• Reduces Inflammation
• Supports Mood and Mental Wellness

Softgel Suitability and Formulation Comparison

Fish oil has more points for softgel production. It is stable and easy to work with. Although you have to be careful while using cod liver oil, it needs a bit high maintenance. It breaks down quickly when exposed to heat or light, so you’ll need extra stabilizers to keep it fresh.

Which One Should You Choose for Your Nutraceutical Brand?

Choosing the right oil base for your nutraceutical supplement really comes down to a few key things:

• Your manufacturing budget 
• Dietary goals for the end product

If you mainly want omega 3s, fish oil is a good choice. If you need supplements for vitamins and omega 3, opt for cod liver oil.

Another factor is product stability and ease of formulation. You can make shelf stable supplements using fish oil without adding expensive stabilizers.Conversely, refrigeration is required for cod liver oil supplements because they are heat-sensitive and spoil faster. Cod liver oil needs more maintenance and it breaks down faster under heat or light and often needs antioxidants to stay stable. That means more production costs and stricter quality checks. 

Fish oil is simpler to handle and more cost-effective, which makes it a go-to for many brands. Either way, SaintyCo has the tools and expertise to help you create premium omega-3 softgels that meet your goals and your budget.
