Essential Omega 3 Fatty Acids & Fish Oil Supplements FAQs

Q: Why should I take fish oil supplements?

A: Fish oil supplements supply the essential fatty acid, Omega-3. Omega-3 can only be obtained from the food and supplements we consume. Because the typical American diet is very low in Omega-3 fats, it is very beneficial to supplement your dietary intake of Omega-3 with fish oil supplements.‡

Q. What are essential fatty acids?

A: Essential fatty acids (EFAs) are good-for-you fats the human body cannot make on its own. For this reason, we need to get our EFAs from food or supplements. Technically, they are long-chain unsaturated fatty acids. Fatty acids are building blocks used in every cell in your body. From their cellular position, EFAs direct and manage vital body functions, such as inflammation and proper heart, joint, eye, brain and immune function.

Q: What are the main benefits of taking fish oil supplements?

A: Omega-3 oils are essential to healthy digestion and help nourish the cells in the intestinal tract as well as provide the lubrication necessary for regular, healthy bowel elimination.‡ They have also been shown to significantly improve overall health by supporting the nervous system, brain, heart and other organs.‡

Q: Do your fish oil supplements have enteric coating?

A: Yes, burp-free enteric-coated capsules deliver oils directly to the intestines for no fishy aftertaste or 'repeat' and better absorption of the Omega-3s. ReNew Life also adds plant lipase (a natural fat-splitting enzyme) that helps the body digest and absorb the beneficial oils.‡

Q: Are your fish oil supplements truly burp-free?

A: Yes, our enteric-coated capsules not only deliver oil directly to the intestines for better absorption, but they also ensure you will experience no fishy aftertaste or 'repeat'.

Q: Is fish oil safe?

A: Yes. Fish oil supplies Omega-3s, which are the “good fats” that support health and vitality, but that our bodies cannot make on their own.‡

Q: Are there any side effects from taking fish oil supplements?

A: Our fish oil supplements provide nutrients your body needs, and in general there are no side effects.‡ It is advised that people taking blood-thinning medications be under a doctor’s care when taking fish oil.

Q: Is it safe for children to take fish oil?

A: It is safe for children to take fish oil supplements, and it will support their developmental health.‡

Q: Are your products certified?

A: Yes, we are one of only a few companies that publishes the results of tests on our products by the International Fish Oils Standards program, which awards them the maximum 5 stars for purity ,potency, and freshness. Search “ReNew Life” at: http://www.ifosprogram.com/consumer-reports.aspx

Q: Are your fish oil formulas tested for purity?

A: Yes. The complete line of one-a-day oil formulas has earned a 5-star rating by the International Fish Oil Standards (IFOS) program, proving they meet or exceed all national and international standards for purity, potency and freshness.

Q: How do I know your fish oil supplements are fresh?

A: Our exclusive Fresh-Assure blue glass bottles and dark-colored capsules help seal in freshness and shield the pristine oils from the harmful effects of light. ReNew Life also uses oxygen-free processing from formulation to bottling, which guarantees the absolute freshest oils available. Our IFOS testing ensures stability of every batch with low peroxide, anisidine, and total oxidation levels along with low acid values. 

Q: Are your fish oils tested for radiation?

A: Yes, we have been testing our fish oil for radiation since 2011 and have processes in place to continue testing indefinitely. Results obtained to date have all been below the detection limit, so we can safely state that our products are not at risk for radiation exposure.

Q: Should I be concerned about toxins, heavy metals, pesticides or other pollution in fish oil supplements?

A: Our fish oils are sourced from smaller, wild, cold-water fish that are naturally lower in environmental toxins such as mercury, PCBs and pesticides. In addition to anchovies and sardines, salmon, mackerel and tuna may also be used, depending upon blend, season and catch. Most of our fish oil supplements are purified through a process called molecular distillation or supercritical extraction—processes by which harmful materials (heavy metals, mercury, PCBs, and other toxins) are removed from the fish oil.

Q: I am a vegetarian; do you use animal gelatin?

A: No, we use fish-derived gel caps that are ideal for fish-eating vegetarians and others who wish to avoid animal-based softgels.

Q: If I'm allergic to fish, is it safe for me to take fish oil?

A: To be absolutely safe, it is best if you get your Omega-3 from plant sources, such as flaxseed oil.

Q: What is the best time to take fish oil? And should I take fish oil with food?

A: You can take fish oil with or without food, or as directed by your healthcare practitioner.

Q: Can the softgels be opened if they are too big to swallow?

A: Yes, but you would not get the advantage of the enteric coating, which ensures targeted delivery and absorption for a burp-free experience.‡

Q: Can I take fish oil with other vitamins?

A: We recommend taking fish oil as part of a healthy dietary and supplementation regimen. Anything that you can do to avoid nutritional deficiencies will greatly improve your health and wellness. It is always best to keep your physician informed of your dietary regimen.

Q: Can I take fish oil with prescription medications?

As a precaution, we recommend consulting your physician or health care practitioner before taking fish oil if you are currently taking any type of medication.

Q: Fish oil has sometimes caused me to have an upset stomach. What can I do to avoid that?

A: Lower-quality products that have not been purified and distilled can often cause an upset stomach, as well as capsules that have spoiled. If you see cloudy deposits in the oil inside your capsules, it can mean they are rancid and should not be taken. ReNew Life uses enteric-coated capsules so the beneficial oils are delivered directly to the intestines for better absorption and no fishy aftertaste or 'repeat'.‡ We also add plant lipase (a natural fat-splitting enzyme) to further help the body digest and absorb the oils.‡

Q: What is Omega-3?

A: Omega-3 is a sub-group of essential fatty acids. Flax seed and some plants provide an Omega-3 fat (ALA), but seafood, fish and fish oil provide the two most biologically functional Omega-3 fats (EPA and DHA). Research shows that most Americans do not consume enough Omega-3 and confirms that consuming adequate amounts of Omega-3 from fish oil improves health and may reduce the risk of heart disease.‡*

Q: Does it matter how much Omega-3 is in my capsule?

A: Yes, so be sure to look at the total amount of Omega-3 in each capsule—not the total amount of fish oil. Supplements vary greatly in the amounts of Omega-3, and our fish oils typically have the highest potency of Omega-3 available.

Q: How do you ensure high levels of Omega-3 EPA & DHA?

ReNew Life uses both molecular vacuum distillation and supercritical CO2 distillation to achieve the high concentration of beneficial Omega-3 EPA and DHA found in our fish oils.

Q: How do molecular vacuum distillation and supercritical CO2 distillation differ?

A: Both are safe and widely used practices to purify and concentrate fish oils. Molecular vacuum distillation uses nitrogen in a high vacuum to minimize heat and achieve a high concentration of Omega-3, while supercritical CO2 distillation uses carbon dioxide and pressure to ensure super concentration of Omega-3.

Q: Is either process harmful to fish oils?

A: Both distillation processes take place in a completely controlled environment and only for short periods of time to ensure the oils are not damaged in any way. The boiling temperature of fish oil is around 480°F, so exposing oils to much lower temperatures for distillation purposes is not harmful to the fish oils or their active constituents. (A good example is cooking fish: typically the method for cooking fish is broiling or baking at temperatures up to 375°F, which does not compromise the quality of the good fats present in the fish.)

Q: What are EPA and DHA?

A: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are two healthy Omega-3 fats found in fish, seafood, and seaweed. EPA and DHA have been researched extensively and are known to be beneficial for heart health, joints, the immune system, healthy mood and brain health.‡

Q: How much Omega-3 EPA and DHA do most people get each day?

A: The average American consumes fewer than 0.2 grams (200 mg) of Omega-3 EPA/DHA per day.

Q: What is the recommended daily intake of Omega-3 EPA and DHA?

A: The American Heart Association recommends people with known coronary heart disease take approximately 1 gram (1,000 mg) of EPA/DHA daily.‡ For people who have no known heart disease, they recommend the equivalent of 500 mg of EPA/DHA daily.‡

Q: What is the recommended daily intake of Omega-3 EPA and DHA for people who want to support healthy triglyceride levels?

A: The American Heart Association reports that supplementation with 2–4 grams (2,000–4,000 mg) of EPA/DHA can help lower triglycerides.‡

Q: Is it possible to take too much Omega-3?

A: Due to its potential blood-thinning effects, it is recommended that you consult your physician when taking high doses of Omega-3 EPA/DHA—particularly doses greater than 3 grams (3,000 mg) per day.

Q: Do fish oil capsules require refrigeration?

A: It is best if they are stored in a cool, dry place rather than in conditions of extreme heat or cold, but it is not necessary to refrigerate them.


*Supportive but not conclusive research shows that consumption of EPA and DHA Omega-3 fatty acids may reduce the risk of coronary heart disease.
