What To Know About Taking A Highly Concentrated Epa Supplements For Your Lipids
Not everyone at risk for cardiovascular disease needs a fish oil supplement highly concentrated in EPA. As discussed above, both EPA and DHA combined have been shown to significantly benefit heart and vascular health. Plus, there are many additional ways to lower LDL naturally while still taking fish oil high in both EPA and DHA. But if youve been taking fish oil and have noticed a negative effect on your LDL, consider trying a high-EPA fish oil for your cholesterol and cardiovascular health.
Anyone who has spent time perusing the seemingly endless brands of fish oil in their local store already knows EPA and DHA amounts vary tremendously between products. Always look for the specific amounts of EPA and DHA listed in the ingredients section of the label.
If you decide to try a fish oil highly concentrated in EPA to improve your lipids without raising LDL, aim for a total daily dose of at least 1800 mg EPA, based on evidence from clinical studies. Many high quality fish oil companies now selling fish oil capsules with enhanced amounts of EPA.

The 411 On Consuming Omega 3 And Omega 6
When discussing dietary ways to lower cholesterol, I spend time educating clients on the importance of seeking out more omega 3 fat-containing foods, especially those found in fish, as a means of lowering LDL cholesterol, says Liz Wyosnick MS, RDN, a registered dietitian in Seattle, and owner of the private practice: Equilibriyum. EPA and DHA , found in marine life are considered the most anti-inflammatory fats due their downstream effects once metabolized in the body. If you displace omega 6 fat-containing foods with omega 3 fat containing foods, LDL cholesterol may lower and overall health is supported with lowered inflammation.
In addition to eating foods rich in omega 3, to help stabilize and lower harmful LDL levels, you may want to avoid eating foods rich in omega 6. This includes food like soybean oil , corn oil, and condiments like mayonnaise.
Cholesterol Ester Transfer Protein And N
CETP is a plasma glycoprotein secreted by the liver which enables the exchange of cholesteryl esters between HDL and other lipoproteins, such as LDL, thereby promoting hepatic clearance of macrophage-derived cholesterol, via an indirect pathway by hepatic LDLr.
CETP transgenic mice treated with fish oil containing n-3 PUFAs showed significant increases in CETP plasma levels and activity, as well as elevated CETP mRNA expression in the liver . The authors hypothesized a PPAR-related induction of CETP transcription through binding of n-3 PUFAs to PPAR response elements in the CETP gene , since PUFAs have been described as natural ligands for PPAR . In a recent study in hamsters fed a high-fat diet and administered EPA or DHA, distinct results for the CETP-LDL cholesterol pathways were observed . It was found that DHA, in contrast to EPA, led to a significant increase in LDL cholesterol concentrations, an increase in plasma CETP activity as well as elevated CETP mRNA expression in adipose tissue. The effect of EPA on the same parameters, however, was less prominent and suggests that the impact of n-3 PUFAs on CETP and RCT may depend on the type of n-3 PUFA administered . These findings underline the importance of distinct analyses of different PUFA subclasses, as they may exert differential effects on cholesterol metabolism .

Increase Your Consumption Of Dietary Fiber
Ideally, you should be getting 25 to 35 grams of fiber a day, says Dr. Cho. Fiber binds to cholesterol and eliminates it from your body.
To increase your fiber intake, eat more whole grains, legumes like beans and lentils, vegetables and fruits. You should be getting a good mix of both soluble fibers, which are more beneficial for cholesterol, and insoluble fibers, which are better for your gut health.
Lower cholesterol isnt the only benefit of getting enough fiber. Other benefits include reducing your risk of diseases, preventing constipation and keeping you full longer.
Raising Your Level Of Hdl
HDL cholesterol is made by our body and is in a large part determined by our genes. By making changes on how active we are and what we eat can help increase HDL cholesterol.
What should we aim for?HDL of 60mg/dL and above is considered protective against heart disease.
Physical Activity: Every bit counts: taking the stairs, walking, biking, and weight training. You do not have to be an Olympic athlete, but you need to be active most days of the week.Quit Smoking: Will increase HDL, decrease heart disease risk and some cancers.Weight Loss: If overweight, weight loss of 5% -10% helps increase HDL cholesterol
Omega 3 fats:
Fish: Eating 2-3 fish meals per week has shown to increase HDL cholesterol. This is linked to the Omega 3 Fatty Acids. Fatty fish are best
Fish Oil supplements: look at the label and add up the EPA and DHA. Take enough capsules to equal 1,000mg daily. Check with your cardiologist or PCP before starting this supplement.
Eat Less Sugar and Refined Carbohydrates
Eat Fiber rich Foods instead: Whole or cut fruit, vegetables, salads, legumes, whole grains
Avoid Trans-fatty Acids: Avoid foods that have partially hydrogenated oils. Read the ingredients list to find them. These oils raise LDL cholesterol and lower HDL cholesterol.

How Can We Practice A Sustainable Diet Rich In Omega
A practical way to put this recommendation into place is to commit to eat at least two meals based in fish each week, says Wyosnick MS, RDN. The best food sources come from oily fish like salmon, sardines, mackerel, and herring. However if youre a vegetarian, or not a fan of fish, increase your omega-3 intake by eating foods like chia seeds, brussels sprouts and walnuts. By focusing on adding in food sources of omega-3 fatty acids, you can displace the typical foods high in omega-6. Other recommendations that I share is to use olive oil as often as possible for cooking, reduce packaged foods, and cook meals more at home to lower the load of omega-6 fats, says Wyosnick MS, RDN.

Why Are Omega 3 Fats Good For Health
There has been lots of research into Omega 3 fats and oily fish and how they can improve heart health.
In countries where people eat more oily fish, such as in the Mediterranean, Greenland and Japan, fewer people have heart disease compared to countries where people eat very little oily fish, such as the UK.
The Omega 3 fats EPA and DHA can help protect the heart and blood vessels from disease: They can help:
- lower triglycerides
- improve circulation
- prevent blood clots
- lower blood pressure
- keep the rhythm of your heart steady.
In the past, higher levels of the Omega 3 fats EPA and DHA in the blood have also been linked with a lower risk of dying from cardiovascular disease. There is still research on-going, but doctors think that the benefits come from eating foods that contain omega 3s rather than over-the-counter supplements. However, some high-dose Omega 3 supplements may be prescribed by your doctor to treat hypertriglyceridaemia.

The New Scientific Advisory Zeros In On Triglyceride Effects And On Newer Prescription
Prescription-strength omega-3 fatty acids, available at the US Food and Drug Administration-approved dose of 4 g/day, are a safe and effective treatment for reducing triglycerides among individuals with hypertriglyceridemia, according to a new scientific statement from the American Heart Association .
Before omega-3 fatty acids are prescribed, however, physicians should first address any potential secondary causes of high triglycerides, such as hyperthyroidism or poorly managed type 2 diabetes, as well as implement a strategy to modify diet and lifestyle.
If these changes are not possible or not effective, initiating triglyceride-lowering pharmacotherapy may be required, write Ann Skulas-Ray, PhD , and colleagues in a paper published online August 19, 2019, in Circulation.
The science advisory updates prior AHA documents focused on omega-3 fatty acids, dating back to 2002 and 2011, that predate the advent of purified, prescription-strength formulations. The document also focuses specifically on their effects on hypertriglyceridemia, rather than atherosclerotic vascular disease.
To TCTMD, Skulas-Ray stressed that the degree of treatment response to omega-3 prescriptions is determined by the severity of an individuals triglyceride levels prior to treatment. She also noted that levels are highly variable day-to-day, so the determination of response shouldnt be based on a single triglyceride measurement.
Modify Your Eating Habits
A great way to lower your cholesterol naturally is to start by replacing unhealthy fats with healthy fats .
This means becoming a food label reader, says Dr. Cho. Its important to limit your saturated fat intake. There should be no more than 2 grams of fat per serving and it should account for less than 7% of your daily calorie intake.
Saturated fats are most often found in palm oil and coconut oil, along with animal products like beef, pork, chicken skin, hot dogs and regular cheese.

Do They Have A Direct Relationship With Cholesterol
As there are mixed reviews on how omega-3 and omega-6 fatty acids affect cholesterol, its best to lay out all the knowledge and findings out there. While the American Heart Association and Heart Foundation, claim that consuming polyunsaturated fats help increase HDL levels and lower LDL levels , it may be the case that not all polyunsaturated fats are considered equal. According to the International Food Information Council Foundation, omega-3 fatty acids decrease serum triglyceride and total cholesterol levels, and may increase or have no effect on high-density-lipoprotein cholesterol, while diets high in omega-6 fatty acids are associated with lower blood levels of total cholesterol and LDL-cholesterol, but also with lower blood levels of the protective HDL cholesterol. Overall, this means that our bodies may be out of sync in our omega-3 to omega-6 balance. Omega-3 seems to have a better outlook for healthy HDL levels than omega-6, which focus more on LDL levels.
Should I Be Concerned About Mercury In Fish
Mercury occurs naturally in the environment and as a result of industrial pollution. It falls from the air and can collect in streams and oceans, where it is converted into methylmercury. Too much methylmercury can be harmful. This is especially true for unborn and young children.
Some fish have higher levels of mercury than others. These include shark, swordfish, tilefish, and King mackerel. Everyone should limit the amounts of these fish in their diet. Women who are pregnant or nursing and young children should not eat these types of fish. Women who are pregnant or nursing can safely eat 12 ounces of other types of fish each week. These include shellfish, canned fish and smaller fish.
Albacore Tuna has more mercury than canned light tuna. Limit the amount of albacore tuna you eat to 6 ounces per week.

A 2015 study from Penn State University found that obese or overweight people had a 50% drop in LDL levels after following an avocado-rich, low-fat diet for five weeks. An earlier study from Mexico reported that a similar diet in healthy people with mild hypercholesterolemia reduced total cholesterol by 17% and bad LDL cholesterol by 22% after only seven days.
Fish Oil Supplements Do Not Raise Ldl
Data from a predominantly male, normolipidemic, middle-aged cohort of 9,253 individuals indicated that fish oil supplementation was not associated with increases in LDL-cholesterol levels.
In addition, fish oil supplementation was associated with increases in red blood cell levels of DHA.
ncreases in the omega-3 index and in erythrocyte DHA over time were associated with modestly decreased levels of LDL-C, wrote the researchers, led by Dr William Harris from the Fatty Acid Research Institute .
These findings can reassure individuals who, in making healthier lifestyle choices, want to increase their intake of omega-3 fatty acids , that clinically significant adverse effects on LDL-C are unlikely to occur.

Fact Versus Fiction: The Benefits Of Omega
We value vitality here at Biomega. Its why we continually strive to create products that not only help keep us and our pets healthy, but also offer beneficial health gains through improvements to overall wellness. Vital to our business portfolio and sourced from our fresh Norwegian salmon rest streams, Omega-3s are essential fatty acids that contain many proven health benefits. Since they play such an important role in human health, the factual health benefits occasionally crossover with fictional ones. These misconceptions can sometimes deter individuals from consuming the recommended weekly amount. For example, some believe that omega-3s are just for those with heart disease a clear myth. To understand why some consumers may believe fiction over fact, lets first explore the numerous health benefits that Omega-3s can bring to human nutrition.
Omega-3 in a Nutshell
There are three main types of omega-3s: ALA found in plants, DHA and EPA found in animal foods and algae. Foods that are rich in omega-3s include some oils , green leafy vegetables, walnuts and seeds . Oily fish, such as salmon, mackerel and sardines, are also naturally rich in EPA and DHA. In fact, the British cholesterol charity Heart UK recommends consuming at least one portion of oily fish per week. Yet when it comes to cholesterol and omega-3s, its easy to get confused.

What About Supplements
Here at HEART UK we dont recommend supplements of Omega 3s. Its always best to get your nutrients from foods rather than supplements.
Thats because foods contain a whole range of different nutrients which improve your health in different ways. But supplements only contain specific nutrients.
If you choose to top up on Omega 3s by using over-the-counter supplements, follow these golden rules.
- Choose a fish oil or an Omega 3 supplement.
- Dont choose fish liver oils, they contain less Omega 3 than fish oils and too much vitamin A.
- Go for a supplement with lower levels of vitamin A less than 1mg per day .
- If you are pregnant or breastfeeding, avoid supplements that contain vitamin A altogether. Beta carotene .
- Aim to get 500mg of EPA and DHA combined each day, this works out as around the same as a 140g portion of oily fish per week.
- If you take medicines to thin your blood, such as aspirin, warfarin or heparin, speak to your doctor before taking fish oil supplements they can also thin your blood.
- If you are vegan or vegetarian, you can take marine oils made from algae.

Where Do We Stand
Back to my patients who want to know if they should be taking an omega-3 supplement. With the availability of todays data, I would recommend a pure EPA supplement, or one that contains more EPA than DHA. But dont stop there. Eat a heart-healthy diet, get regular exercise, and pursue other lifestyle changes that have proven benefits for cardiovascular health. In the meantime, my colleagues and I wait for more definitive data on the utility of omega-3 fish oil, and who might benefit the most.
How To Choose The Right Fish Oil Supplement
There are hundreds of choices of fish oil supplements. However, not all are created equal. According to Labdoor, almost half dont contain the daily recommendation of 500 mg of omega-3 fatty acids. Additionally, some are contaminated with mercury and other toxins. So it’s best to make sure whichever supplement brand you choose is third-party tested and is transparent about heavy metal testing and where exactly the firsh oil is sourced. Each manufacturer provides recommended daily dosages. However, we suggest consulting with a nutrition or healthcare professional a choose a dose based on your specific biomarkers.
Keep in mind that while fish oil supplements have proven benefits, we recommend getting some of your omega-3 acids from natural sources such as fatty fish, flaxseed, chia seeds, and walnuts. These whole foods also contain many other nutrients and healthy substances that maximize the benefits of fish oil supplements. Two to three servings of fatty fish per week satisfy the weekly requirement of omega-3 fatty acids. If you do not like these foods or find them hard to fit into your diet, supplements might be most beneficial.
