7 important factors to consider when choosing a fish oil: Fish Oil Buyers Guide
Purity: The purity of the fish oil is crucial because it directly impacts your health. Look for a brand that has been tested by an independent third party and is free from contaminants like PCBs, heavy metals, and dioxins.
Freshness: Fish oil can easily become rancid, which can cause unpleasant side effects such as indigestion and diarrhea. Choose brands that use fresh fish with minimal processing and have a low oxidation rate.
Nutrients: The nutrient content of fish oil varies depending on the type of fish used and the processing method. Look for a brand that contains high levels of EPA and DHA, the two main omega-3 fatty acids found in fish oil.
Bio-availability: The body’s ability to absorb and utilize the nutrients in fish oil is vital. Choose a brand that uses a form of fish oil that is more easily absorbed, such as triglyceride form or phospholipid form.
Sustainability: The fishing industry can have a significant impact on the environment. Choose a brand that sources their fish from sustainable and responsibly managed fisheries.
Cost: Although cost is a factor to consider, it should not be the only deciding factor. Choose a brand that offers high-quality fish oil at a reasonable price.
Krill Oil: While krill oil has gained popularity in recent years, there is not enough scientific research to support its efficacy over fish oil. Additionally, krill populations are declining, making it unsustainable for long-term use.
