Which Prescription Fish Oil Capsules Are Available To Treat Hypertriglyceridemia
Several prescription fish oil capsules have been approved by the FDA to treat triglyceride levels of more than 500 mg/dL. A report by Hilleman and Smer states that omega-3 fatty acid products available in prescription formulations have been found to significantly reduce triglycerides. In patients with baseline triglyceride levels of 500 mg/dL or greater taking 4 g/day of a prescription product, decreases compared with placebo ranged from 12.2% to 51.6%. Unlike the supplements, the prescription products are subject to FDA approval, and their safety and efficacy must be established prior to marketing. Currently, prescription capsules contain either a combination of EPA and DHA or EPA alone. There is some concern regarding the use of DHA in patients with dyslipidemia, since high-dose omega-3 products containing DHA increase LDL cholesterol levels the impact on HDL cholesterol levels varies.
One example of a prescription product is Lovaza. One 1-g capsule contains at least 900 mg of ethyl esters of omega-3 fatty acids . Another prescription omega-3 fatty acid product, Omtryg, was approved by the FDA in 2014 and contains EPA and DHA in the same amounts as Lovaza.
A third prescription fish oil is an ultra-pure omega fatty acid that contains an ethyl ester of EPA, icosapent ethyl . Each 1-g icosapent capsule contains at least 96% EPA and no DHA. Past studies suggest that highly purified EPA may lower triglyceride levels without increasing LDL cholesterol levels.
What Exactly Is Fish Oil
Fish oil supplements contain oils derived from the skin and liver of fatty fish such as mackerel, tuna, sardines, and salmon. They are an excellent source of omega-3 fatty acids, a polyunsaturated fat that helps protect against heart disease and possibly other health conditions . Omega-3 fatty acids come in three varieties. One is alpha-linolenic acid , found in vegetable oils such as soybean, canola, and walnut. The other two are eicosapentaenoic acid and docosahexaenoic acid , only found in fatty fish and fish-derived supplements. Though Omega-3 fatty acids are essential to humans, they cannot be produced by the body and must be consumed through diet or supplementation. Unfortunately, most Americans dont get enough of any of these types of omega-3 fatty acids in their diets. So, many people look to fish oil supplements to gain their daily recommended value of omega-3 fatty acids and gain its heart-healthy benefits.
A Cardiologist’s Top 10 Things To Know About Fish Oil Supplements
There’s more to consider about taking this common product than you may know.
Who knew that the decision to take a simple supplement like fish oil could be so complicated?
Omega-3 fatty acids may help decrease inflammation and decrease the risk of developing heart disease. At first, taking a supplement seems to be an easy decision. After all, why eat fish if you can get the active ingredients in a pill? Manufacturers tout the benefits relentlessly, but sometimes push so hard it seems as if they are trying to sell snake oil. Contrast that with studies suggesting that taking fish oil is worthless, or may cause harm. What does the evidence suggest? Here are some important things to consider:
Despite many studies done over the last few years, there is no absolute proof that taking omega-3 fatty acids will decrease your risk of having a heart attack. Studies are in progress to determine whether adding omega-3 fatty acids to a medical regimen including statins will lower your risk of a heart attack if you already have coronary artery disease.
DHA and EPA are the active ingredients in omega-3 fatty acids and have been shown in multiple studies to lower triglyceride levels. Triglycerides are a kind of fat, very different from cholesterol, that can cause irritation of the lining of blood vessels, especially when accompanied by low HDL cholesterol.

Too much of a good thing — in this case, the B vitamin niacin — can be downright dangerous! Niacin can help lower cholesterol, but at high doses, it can raise blood sugar levels in people with diabetes. Niacin can also cause flushing, a warm feeling and red color in the face and neck, as well as headaches, blurred vision, heartburn, and other unpleasant side effects.

What If Im Allergic To Fish Or Dont Want To Eat Fish
Fish is the best food source of omega-3 fatty acids, but several plants contain ALA. This is not as rich of a source of omega-3 fatty acids, but some studies show that ALA can reduce the risk of cardiovascular disease.
Good sources of ALA are ground or milled flaxseeds, flaxseed oil, chia seeds, walnuts, soy foods and canola oil. Another source of ALA is algae or algae oil, which is broken down to DHA. Many foods that are fortified with omega-3 use algae oil. These are excellent options for vegetarians that do not eat fish.
There are currently no serving size recommendations for ALA-rich foods. But, adding these foods to your diet regularly may help your heart health.
Mercury And Heavy Metals
Sometimes, mercury and other hard metals can build up in fish because of environmental pollution. This is more likely to affect larger fish , but since we often eat or press these larger fish , we are at risk for higher mercury levels. Older studies have found that almost 90% of people have higher mercury levels than recommended, and those who ate more fish were more likely to have higher levels.
However, that doesnt mean that you should completely avoid fish or fish oil. Heavy metals are almost always removed during the refining and processing of fish oil. Both independent third-party testing organizations and researchers have come to the same conclusion: virtually no fish oil supplements on the market contain mercury. Before being sold, most fish oil supplements are tested for mercury and other heavy metals to be sure. This information should be readily available in a Certificate of Analysis or third-party testing results.
If youre concerned about your mercury levels, our guide to the best at-home heavy metal tests might help soothe your worries.

Fish Oilreduces Vldl Production
Yourliver is a very important organ.
Itdoes many jobs in your body, such as:
- Storing glycogen
Lipoproteins,such as VLDL , are made to transporttriglycerides to your tissues.
Now,high levels of VLDL increase your triglycerides in 2 ways. They:
- Increase triglyceride production directly
- Reduce the clearance of triglycerides in your blood
So, a great way to reduce your triglycerides is to lower your VLDL levels.
A study compared the production of VLDL after supplementing with either fish oil or safflower oil.
The results showed that those who took fish oil had a huge reduction in VLDL compared to those who took safflower oil.
When Are Your Triglycerides Too High
Triglyceride levels are measured through a blood test.
Your triglyceride level result is according to the National Heart, Lung and Blood Institute, National Institutes of Health, and U.S. Department of Health and Human Services.
- Normal Less than 150 mg/dL
- Borderline-high 150-199 mg/dL
- Very high 500 mg/dL or above

Ingredients & Potential Interactions
It is essential to carefully read the ingredient list and nutrition facts panel of a supplement to know which ingredients and how much of each ingredient is included relative to the recommended daily value of that ingredient. Please bring the supplement label to a healthcare provider to review the different ingredients contained in the supplement and any potential interactions between these ingredients and other supplements and medications you are taking.
Fish oil supplements typically contain EPA, DHA, and may also contain other fats such as omega-7 , oleic acid, or an omega-6 fat called GLA. Some fish oil supplements contain added vitamins, such as vitamin E, to help stabilize the oils to prevent them from going rancid.
Fish oil supplements can have a blood-thinning effect and may lower blood pressure slightly. If you are taking blood-thinning or blood pressure lowering medication, be sure to discuss fish oil supplement use with a healthcare provider.
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.

Cardiac Mortality Sudden Death And All
The Diet and Reinfarction Trial 4 was one of the first studies to investigate a relationship between dietary intake of omega-3 fatty acids and secondary prevention of myocardial infarction. In this study, 1,015 men were advised to eat at least two servings of fatty fish per week, and 1,018 men were not so advised. At the two-year follow-up, the men who had been advised to consume fish had a 29 percent reduction in all-cause mortality but no reduction in the incidence of myocardial infarction.4
Sudden death caused by sustained ventricular arrhythmias accounts for 50 to 60 percent of all deaths in persons with coronary heart disease .5 To date, the largest, prospective, randomized controlled trial on the effects of omega-3 fatty acids is the GISSI-Prevenzione Trial.6 This study included 11,324 patients with known CHD who were randomized to receive either 300 mg of vitamin E, 850 mg of omega-3 fatty acids, both, or neither. After three and one-half years, the group given omega-3 fatty acids alone had a 45 percent reduction in sudden death and a 20 percent reduction in all-cause mortality.6
Follow A Lower Carb Diet
Much like added sugar, extra calories from carbs in your diet are converted into triglycerides and stored in fat cells.
Not surprisingly, low carb diets have been linked to lower blood triglyceride levels .
A review of 12 randomized controlled trials found that people following reduced carb diets typically saw a reduction in triglyceride levels at 6, 12, and 24 months. Across these studies, triglyceride levels decreased the most 6 months after starting a reduced calorie diet .
A 2020 review compared low fat and low carb diets. Researchers found that 612 months after starting their relative diets, those on the low carb diet had greater decreases in triglyceride levels than those on a low fat diet .
Following a low carb diet can lead to a significant reduction in blood triglyceride levels, at least in the short term, when compared with a low fat diet.

Fish Oils Lower Triglyceride Levels
Though cholesterol gets the most attention, a large body of accumulating evidence indicates that elevations of triglycerides in the blood is also an important risk factor for cardiovascular disease especially in women. When hypertriglyceridemia is combined with elevated LDL cholesterol and high LDL:HDL cholesterol ratio the risk for heart disease is even greater, e.g., approximately sixfold greater compared to subjects with normal blood measurements.
Fish Oils Fight Heart Disease:
A large body of scientific evidence shows that supplementing the diet with highly purified fish oils protect against heart disease via a number of different actions including:
- Lowering triglyceride levels
- Lowering high blood pressure
- Improving the function of the blood vessel lining
In large scale clinical studies, these effects translate into increased life expectancy, especially in people who have had a previous heart attack. In general, for preventive effects the dosage recommendation is 1,000 mg EPA+DHA per day and for lowering triglycerides the dosage is 3,000 mg.
In a double-blind study, after 8 weeks of supplementation a daily dosage of 3.4 g EPA+DHA lowered triglycerides by 27% while a lower dosage of 0.85 g had no effect. These results clearly indicate that the effective dosage for lowering triglycerides with fish oils requires dosages of 3 g EPA+DHA per day.

Can I Take 2 Fish Oil Pills A Day
Some people experience gastrointestinal side effects when taking fish oil. If a person experiences this side effect, they may find it helpful to split their fish oil into two doses and take them at different times of the day. People who split their dose in half may need to take each one at different mealtimes.
Oily Fish Or Fish Oil Supplements
It is a good idea to include fish in your diet several times per week. At least half of the intake should be oily fish such as anchovies, herring, or free-range salmon because these fish are particularly rich in omega-3 fatty acids . Preferably choose fish from pure waters and beware that predatory fish such as tuna contains more mercury because it is at the top of the food chain. A herring fillet contains around 1 gram of fish oil, while a free-range salmon steak contains around 3-4 grams. Farmed fish has a lower omega-3 content because they do not have a natural diet. According to the new study, optimal triglyceride lowering is obtained with four grams of fish oil each day, which means that a fish oil supplement is a convenient option for many people, especially for those who dislike the taste of fish. For normal protection of the cardiovascular system, two grams of fish oil daily is sufficient. Fish oil preparations based on free fatty acids have superior bioavailability. Also, make sure to choose a product that is within the safety threshold of the health authorities in terms of peroxide value and content of environmental toxins.
