Q: How long does it take to see results in my dog? A: Depending on how Omega-3 depleted your dog is, you may start to see results in as little as 1 or 2 weeks. On average it may take 6 to 12 weeks to see the full effects of the product.
Q: What is the shelf life? A: The shelf life is 2 years for unopened bottles. Once opened, Omega Benefits needs to be refrigerated. The shelf life of opened, refrigerated bottles is months. Q: Are there any side effects my dog may experience?
A: Omega-3 fatty acids are a very safe and effective treatment for your pets. Dogs with known gastrointestinal or pancreatic issues, should be titrated up to the recommended dose. Dogs that have never consumed omega-3 fatty acids may lack the pancreatic enzyme that breaks down Omega-3 fatty acids and may be sensitive to an increase in this dietary fat.
As a result, some may experience loose stool or diarrhea for the first week or two. Save on today's order when you sign up through the VRS HOME DELIVERY PROGRAM Manage your home delivery options at any time by logging into your account. LEARN MORE. Refrigerate after opening.

| Latest news | Here are some of the main health benefits of omega-3s. In addition to lowering blood pressure and triglycerides, omega-3s may also prevent blood clots that can lead to heart attacks. There, it fortifies the delicate membranes that protect your brain cells, making it critical for short- and long-term cognitive health. Studies on omega-3s' ability to fight depression are encouraging but somewhat inconsistent. However, some research, such as a review in Translational Psychiatry , has found that a dosage of up to 1 gram of omega-3s per day can improve depression symptoms. However, more research is needed to understand how omega-3s can help manage depression. According to a meta-analysis published in Nutrients , research reveals that DHA may tame the inflammation that causes dryness and boost tear production for better lubrication. As of March , the United States doesn't have an official omega-3 recommendation. According to the Food and Drug Administration , taking up to 5, mg daily is safe. Soft gels are the most popular form of omega-3 supplement. They come in different sizes, so if you aren't a fan of large pills, you can take several small ones instead. To prevent "fish burps," look for enteric-coated capsules. Since EPA and DHA have slightly different benefits, look for a supplement that contains both. The average omega-3 supplement contains roughly mg of DHA and mg of EPA, although this varies from brand to brand. Fish oil supplements contain lower levels of mercury, PCBs, dioxins and other environmental contaminants than fresh fish, says Natker. If you want extra assurance, look for products with third-party certification tested for contaminants. In addition to checking the "best by" date on the package, follow your nose. Any time works, but taking your supplement with a fat-containing meal helps boost omega-3 absorption even more, says Natker. Even though the United States doesn't have an omega-3 recommendation, the European Food Safety Authority recommends consuming mg of EPA plus DHA daily to mg if you are pregnant or nursing. You may not need a supplement if you eat two weekly servings of fatty fish. However, if you have heart disease, are pregnant or are vegan, talk to your doctor. An omega-3 supplement may make sense if you don't eat a couple of servings of fish per week, but it won't provide other nutrients in fish like lean protein, potassium, B vitamins and selenium.

In addition, because omega-3 and omega-6 fats compete for the same enzymes to produce other fatty acids, it is believed that eating an excess of one type may interfere with the metabolism of the other, thereby reducing its beneficial effects. Many studies and trials in humans support cardiovascular benefit of omega-6 fats. There is no question that many Americans could benefit from increasing their intake of omega-3 fats, but there is also evidence that omega-6 fats reduce cardiovascular risk factors and heart disease. Like many essential nutrients, it is possible that too much can cause problems. However in the U. diet, we have not been able to find individuals or groups who are consuming excessive amounts of omega-6 fatty acids.

ALA: Alpha-linolenic acid ALA , the most common omega-3 fatty acid in most Western diets, is found in plant oils especially canola, soybean, flax , nuts especially walnuts , chia and flax seeds, leafy vegetables, and some animal fats, especially from grass-fed animals. ALA is a true essential fat because it cannot be made by the body, and is needed for normal human growth and development. It can be converted into EPA and DHA, but the conversion rate is limited so we are still uncertain whether ALA alone can provide optimal intakes of omega-3 fatty acids. Is grass-fed beef a good source of omega-3 fats? What is conjugated linoleic acid CLA? This is a type of omega-6 fat found naturally in dairy, beef, and vegetable oils. It is also a popular dietary supplement, produced by chemically changing the structure of polyunsaturated vegetable oils. CLA supplements have been researched as a weight loss aid by reducing body fat; however findings have conflicted. Some studies show a modest short-term weight loss while others show no weight changes. Some reported negative side effects include loose stools and fatty liver that may occur when taken in high dosages in supplements. References NIH Office of Dietary Supplements. Omega-3 Fatty Acids.

are still generally fed a grain-based diet; to further speed growth they may be given growth hormone and are restricted in movement. One might imagine that cows fed primarily grass would be exposed to a more natural habitat of grazing freely and consuming native vegetation, high in nutrients and omega-3 fats.
They may simply be fed grass or vegetation in a confined space. Regardless if cattle are grain or grass-fed, the majority of fat in the beef is saturated, and the amount of total saturated fat is similar regardless of feeding type. The ratio of saturated to unsaturated fat is also similar for grain or grass-fed cattle, but generally grass-fed beef is leaner with less total fat.
Among grass-fed cows, the amount of omega-3 can vary by types of pasture used for grazing and by the age and breed, as genetics play a role in how fat is stored. Even plant foods that contain ALA generally offer higher amounts than grass-fed beef.
This is represented in the table below, which compares 3 ounces of beef, salmon, and walnuts. Even a more typical 1 ounce serving of walnuts provides over mg of ALA—about 30 times the amount in a 3 ounce serving of grass-fed beef.
Therefore grass-fed beef, though a source of ALA, is not a significant contributor of omega-3 fat in our diets. Source: 1 , 2 , 3 , 4 , 5 via USDA National Nutrient Database for Standard Reference, Legacy Most Americans take in far more of another essential fat—omega-6 fats—than they do omega-3 fats.
Like omega-3 fats, omega-6 fats are a critical part of the structure of every cell of our body and are building blocks for hormones that regulate inflammation, narrowing of blood vessels, and blood clotting.
Normally, these are important functions that protect the body from injury and infection, but a popular claim is that an excess intake of omega-6 fats can over-stimulate these functions, causing more harm than benefit. In addition, because omega-3 and omega-6 fats compete for the same enzymes to produce other fatty acids, it is believed that eating an excess of one type may interfere with the metabolism of the other, thereby reducing its beneficial effects.
Many studies and trials in humans support cardiovascular benefit of omega-6 fats. There is no question that many Americans could benefit from increasing their intake of omega-3 fats, but there is also evidence that omega-6 fats reduce cardiovascular risk factors and heart disease.

Antibiotics, pesticides and other chemicals may be used in raising farmed fish. But the FDA says the levels of contaminants in farmed fish don't seem to be bad for health.

Vascepa reduced blood triglyceride levels, but more importantly, it reduced the number of heart attacks and strokes, the need for a heart stenting procedure to open clogged arteries, and death.
In December , the FDA approved the use of Vascepa to reduce the risk of cardiovascular events in certain patients with, or at high risk for, CVD. But a recent study has raised some questions. The STRENGTH trial , published in JAMA , looked at a different formulation of omega-3 fish oil — a combination of EPA and DHA — to see if it would also reduce cardiovascular risk.
The trial was terminated early due to an interim analysis revealing no difference between the two treatment groups. One possibility is that the different results are due to the different drugs studied.
REDUCE-IT studied a purified formulation of high-dose EPA, which resulted in higher EPA levels. This was similar to the results of another trial , which also found that pure EPA reduced the risk of cardiac events. The STRENGTH trial tested a combination of EPA and DHA. No large study has ever evaluated the effects on cardiovascular outcomes of purified DHA alone, leaving us to wonder whether DHA might counteract the benefits of EPA.
Back to my patients who want to know if they should be taking an omega-3 supplement. 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.
