Another Perspective On The Fish Oil
A 1990 study published in the journal, Arteriosclerosis, Thrombosis and Vascular Biology, provided useful insights into how fish oil affects different lipoproteins and their capacity to transport cholesterol.
For this study, the researchers recruited 33 men suffering from mild hypercholesterolemia and then divided them into 3 groups.
The men in the first group were given 14 g/day of linoleic acid from safflower oil the second group received 9 g/day of alpha-linolenic acid from linseed oil, and the third group got 3.8 g/day of omega-3 fatty acids from fish oil.
The results of the study showed that only fish oil reduced triglyceride levels. Also, only fish oil raised the level of LDL cholesterol. The fish oil group also benefitted from reduced VLDL apoprotein B.
While all three oils reduced HDL cholesterol, the biggest reduction was seen in the fish oil group.
Besides measuring the levels of lipoproteins, this study also measured the activity of the enzymes required for the lipoproteins to transport cholesterol. And this part of the study provided a unique perspective on the activities of LDL and HDL.
The results of the study showed that fish oil
- inhibited the transfer of cholesteryl ester between LDL and HDL by 23%
- reduced the activity of the plasma enzyme, cholesterol acetyltransferase by 21%
- reduced the production of thromboxane by 9%
Another rarely mentioned benefit of fish oil for cardiovascular health is its inhibition of thromboxane synthesis.
May Worsen Insomnia Symptoms
Yes, better sleep is listed as one of the pros of fish oil, but some research suggests too much of the stuff could interfere with sleep.
A March 2015 study in Oxford Medical Case Reports reveals that, for one patient with a history of depression, taking a high dose of fish oil worsened symptoms of insomnia and anxiety. Still, more research is needed to determine fish oils general effect on sleep.

Does Fish Oil Thin Your Blood
Fish oil is a blood thinner, which can be both positive and negative. Because fish oil decreases the time your blood clots, it is important to discuss taking the supplement with a medical doctor.
Fish oil is made up of omega-3 essential fatty acids. Normally, blood platelets’ sticky surface causes blood to form together and clot. Fish oil supplements decrease blood platelet activity, resulting in slower blood clotting and thinner blood.
Blood clots might form in the body’s arteries, leading to blocked blood flow and oxygen. Fish oil decreases the number of dangerous blood clots forming, lessening your risk of heart attack and stroke.

Increases Ldl Levels And Insulin Resistance
Fish oil seems to cause an increase in the levels of LDL or bad cholesterol in people with metabolic syndrome. People with metabolic syndrome are those who suffer from a number of conditions such as increased blood pressure, excess abdominal fat, increased blood sugar and cholesterol levels. They also showed increased insulin resistance as well.8 Some studies show that in people with high cholesterol, fish oil actually adversely affects the ratio of LDL to HDL and in some cases the triglyceride decrease is insignificant.9
Plasma Cholesterol Vs Lipoprotein Cholesterol
A 1986 study published in The American Journal of Clinical Nutrition provided support for the benefits of fish oil omega-3 fatty acids even when combined with high cholesterol intake.
The study involved 6 participants tested with 3 diets. The participants were first placed on a diet providing 710 mg/day of cholesterol. Thereafter, they ate a diet with lower cholesterol content along with 40 g/day of fish oil. Finally, they took the same fish oil supplement and an egg yolk diet with high cholesterol content .
The results of the study showed that switching from a high-cholesterol diet to a low-cholesterol diet plus fish oil supplement reduced cholesterol and triglyceride levels.
The dietary change and fish oil supplementation lowered VLDL, LDL, HDL, and triglyceride levels as well as the level of apoproteins A1 and B.
When the study participants were switched back to a high-cholesterol diet plus fish oil supplement, only plasma cholesterol rose. There was no significant increase in lipoprotein cholesterol or apoprotein levels.
These results showed that even though fish oil supplements may not reduce the amount of cholesterol in the plasma, it can reduce the amount of cholesterol carried by lipoproteins . Since lipoprotein cholesterols are the determinant of cardiovascular health, fish oil can improve cardiovascular health even when plasma measurements indicate it does not lower cholesterol levels.

Manufacturers claim that these fish oil can lower your risk of cardiovascular diseases, improve immunity, and boost athletic performance. But what does the science say? In this article, the research of the effects of fish oil supplements on key health indicators in your bodyespecially triglycerides, cholesterol, and testosteronewill be critically evaluated.
Prescription Vs Otc Supplements
Prescription omega-3 fatty acids contain a certain amount of natural or modified forms of omega-3 fatty acids. They are purified and are thoroughly rid of impurities such as trans-fats, mercury, or other contaminants.
Prescription omega-3 fatty acids are usually taken by individuals with very high triglyceride levels who are in need of larger doses of omega-3 fats to bring their triglycerides down.
Supplements that are available over-the-counter are classified as foods by the U.S. Food and Drug Administration . Therefore, they do not have to undergo the rigorous purification processes or efficacy studies that prescription drugs have to go through.

Diabetes: There has been some concern that cod liver oil or other fish oils might increase blood sugar in people with diabetes. But there is no strong research that supports this concern. High blood pressure: Cod liver oil can lower blood pressure and might cause blood pressure to go too low if used along with medications for high blood pressure. Be careful when using cod liver oil if you are taking high blood pressure drugs.
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.

If youve made some dietary changes and you still havent seen results, try incorporating phytosterol into your diet. Phytosterol is similar to the bodys cholesterol and can block cholesterol from being absorbed into your body.
Phytosterol can lower your cholesterol by 10% and your LDL by 14%, she says. Aim to get about 2 grams of phytosterol a day. Some common food and dietary supplements include high sterol or stanol esters be sure to read the labels.
Heart And Skeletal Muscle
Heart and skeletal muscles are the primary sites for FA utilization, and LpL is highly expressed in both tissues . In both tissues, LpL activity is enhanced by FO . These results suggest that increased removal of TG by heart and skeletal muscle contributes to the plasma TG lowering effect . The uptake of FAs released from VLDL via LpL-lipolysis appears to be more efficient in skeletal muscle than in adipose tissue, suggesting less spillover of FAs into the NEFA pool. FO also increases the expression of genes regulating -oxidation in skeletal muscle . Moreover, the FO-induced increase in plasma adiponectin is likely to have a systemic effect on skeletal and cardiac muscle increasing TG hydrolysis, FA uptake and -oxidation . As a result cardiac and skeletal muscles could facilitate the TG-lowering effects of FO by upregulating FA uptake and oxidation.

High Dose Recommended In Science Advisory
byNicole Lou, Staff Writer, MedPage Today August 20, 2019
Prescription omega-3 fatty acids are an “effective and safe option” to cut down triglycerides, according to a science advisory released by the American Heart Association .
However, over-the-counter omega-3 supplements are not reviewed or approved by the FDA and should not be used in place of prescription medication for the long-term management of high triglycerides, cautioned writing group chair Ann Skulas-Ray, PhD, of the University of Arizona, Tucson, in a press release.
Prescription omega-3 fatty acids “at a dose of 4 g/d, are clinically useful for reducing triglycerides, after any underlying causes are addressed and diet and lifestyle strategies are implemented, either as monotherapy or as an adjunct to other triglyceride-lowering therapies,” her group concluded.
Fish oil products containing eicosapentaenoic acid and/or docosahexaenoic acid taken at that dose have been shown to reduce triglyceride levels by at least 30% in patients with triglycerides of 500 mg/dL or greater, according to the statement published online in Circulation.
EPA-only formulations did not raise LDL cholesterol in this group, whereas combination EPA-DHA did, authors noted.
Among people with hypertriglyceridemia in the 200-499 mg/dL range, the 4-g/day dose of prescription omega-3 fatty acids lowered triglycerides by 20% to 30% without significantly increasing LDL cholesterol.

Cholesterol In The Body
Cholesterol is a waxy substance thats found in all of your cells and has several useful functions, including helping to build your bodys cells.
Its carried through your bloodstream attached to proteins.
These proteins are called lipoproteins. Our LDL or low-density lipoproteins, build up within the walls of our blood vessels and narrow the passageways, as we age.
Significant clots can form in these passageways, causing a heart attack or stroke.
LDL is known as thebad cholesterol.
Our HDL or high-density lipoproteins pick up the excess cholesterol in your blood and take it to your liver, where it is broken down and removed from your body.
HDL is your good cholesterol. However, be aware of your triglyceride numbers too.
High triglyceride levels combined with high LDL cholesterol or low HDL cholesterol increase your risk of heart attack or stroke.
Triglycerides are basically excess fat in your body.
Fish Oil Supplements Don’t Raise Bad Cholesterol
Omega-3 fatty acids have a long history of being heart-healthy and are well-known for lowering blood levels of blood fats called triglycerides.
Recent questions have been raised, however, about one of the two “fish oil” omega-3 fatty acids — DHA — and the possibility that it might actually raise levels of LDL cholesterol.
Theres evidence that people with very high blood triglyceride levels who are treated with omega-3s commonly see a rise in LDL cholesterol. However, whether this occurs in generally healthy people taking fish oil supplements for cardio-protection is not clear.
A recent study from the Cooper Center Longitudinal Study and the Fatty Acid Research Institute sheds new light on this question.

Can I Use Vitamins To Lower My Cholesterol
The only vitamin that really lowers cholesterol is red yeast rice at 1200 mg twice a day, according to Dr. Cho.
The problem with red yeast rice is that it contains the same chemical compound as lovastatin, which means you would need to have your liver function monitored if you take it, she says. The Food and Drug Administration hasnt approved this supplement for medical use, so talk to your doctor before considering it.
All in all, you can lower your cholesterol naturally. Diet should be the cornerstone of therapy and pills are a supplement, not a substitute, for a good diet. Always talk to your doctor before taking any new supplements.
How To Lower Cholesterol Naturally
Here are 6 drug-free alternatives for lowering LDL cholesterol.

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.
