What is Lovaza?

To begin, Lovaza is a prescription omega-3 fatty acid pill that is regulated by the FDA. It is more potent than over-the-counter fish oil supplements. You have to take it in accordance with your doctor’s instructions. This product is intended to treat high triglyceride levels and promote heart health. This may help prevent heart attack, heart disease and stroke. It is typically taken in conjunction with a physician-approved diet and exercise program.

As for Lovaza ingredients, this medication contains omega-3 acid ethyl esters. This may help raise good cholesterol levels. The company behind this product is Glaxo Smith-Kline, and it was approved in the U.S. in 2004. Also, this drug is derived from natural fish oil, but read on…

Steep Price – “Can You Afford It?”

The first concern we have is the price. According to our Research Editor, “The cost of Lovaza is commonly over $100 for 60 capsules. Clearly this is quite expensive when compared to over-the-counter fish oil supplements that often cost less than $10.”

One person posted, “Lovaza is really expensive. This cost me $93 a month. Not cheap.”

Then again, a different user reported, “With my insurance coverage, I only paid $56. Not too bad I suppose.”

Another commented, “Ended up getting Lovaza through Walmart pharmacy. Was less than $60 for 120 capsules.”

Adverse Effects – “Yikes”

Unfortunately, there are some Lovaza side effects to consider. These can include upset stomach, diarrhea, nausea, burping, constipation, dry mouth and back pain. One customer stated, “Gives me bad diarrhea. Not worth the headache.”

But, a different user said this, “Upsets my tummy a little, but nothing major.”

“I get dry mouth and nausea a bit from Lovaza. But I think it’s worth the mild effects,” mentioned another.

The extensive research we’ve conducted has shown if there’s a certain aspect of a diet pill or medication that is quite bothersome or concerning (steep price, adverse effects, customer complaints) the probability of long-term success is low. In other words, if Lovaza does cause unpleasant reactions in a high number of users, this could be a serious issue.

The Science – “Is It Solid?”

At DietSpotlight, we do like to see some real research that backs up the diet product we’re investigating. As for Lovaza, there are some clinical studies to support this medication, which is good to see.

On the other hand, we feel that the steep price and adverse effects are major drawbacks concerning Lovaza. In fact, this may deter many people from trying this prescription fish oil.

What Users Are Saying

"”I’ve been taking this supplement for a while. It has the “good” stuff in it, besides just regular old fish oil. I take one in the morning, and one at night.”"

"”High price but a good product!”"

"”I started burping almost immediately after taking these. I experienced an unpleasant lemon after taste.”"

The Bottom Line – Does Lovaza Work?

Now the moment you’ve been waiting for. Here is our bottom line on Lovaza. To start, we like that this medication is regulated by the FDA, and it’s made from natural fish oil. On the other hand, this product can get quite expensive over time, especially when compared to drugstore omega fatty acid supplements. Moreover, we’re concerned about the unpleasant side effects that can occur with this drug.

If you’d like to shed some extra pounds of fat, then we suggest you choose a product that will not break your bank account, does not lead to unwanted adverse effects and is supported by plenty of encouraging user reviews.

Among the best products we’ve seen this year is one called Dietspotlight Burn. It offers a combination of four unique ingredients, which have been shown in published clinical studies to help improve fat loss and ignite metabolism. We can’t find any negative user remarks at all, it is affordable and comments around the web show people are seeing real results.

The makers of Dietspotlight Burn are so positive about their product they’re offering a Special Trial Offer, which is uncommon.

What You Should Know

Lovaza is an FDA-approved drug to help reduce high triglyceride count, which are contributing factors to heart disease and stroke. Lovaza is typically prescribed to dieters who want to lower these levels that cannot be naturally obtained through diet, and there is evidence it may substantially lower those levels. Dieters probably know Lovaza by its alternate name, Fish Oil, but Lovaza is a modified version of this supplement. Lovaza is currently available through prescription, and is currently the only way to obtain this supplement. When diet and exercise are not enough, lowering high triglyceride levels through a supplement may be one option considered. Lovaza tends to differ from other supplements because it is FDA-approved, meaning its benefits have been substantially proven by rigorous scientific studies. Lovaza may not be appropriate for everyone.


Lovaza is an Omega-3 polyunsaturated fatty acid, commonly called Fish Oil.

Product Features

Lovaza is essentially a modified type of Fish Oil that is medically proven to lower high triglyceride levels, which may lessen the chances of developing heart disease. Lovaza differs from natural Fish Oil because it said to be more pure and goes through a lengthy process to remove mercury and toxins naturally present in the supplement. This is why proponents of Lovaza say it is a safer and more effective alternative to Fish Oil, which may still contain traces of Mercury. According to evidence reported by the FDA, Lovaza absorbs inside the body and attacks the chemicals that cause high triglycerides. In most cases high triglyceride count lowered at a significant rate, but Lovaza does state that individual results may vary. Like any FDA-approved drug, however, it does come with a list of side effects, including back pain, upset stomach, and skin rash. Dieters with diabetes or a thyroid disorder may also not be eligible for this drug, due to how it interacts with these conditions. It is vitally important to state that Lovaza is mainly prescribed to consumers already dieting to lower high triglyceride levels, and deviating from the diet or consuming high fat substances may interact negatively with the medication.


  • Is an FDA-approved drug for the treatment of high triglyceride levels.
  • Is a natural drug derived from Fish Oil.


  • Is not used to help consumers lose weight. It only used to aid issues related to weight loss.
  • May contain unpleasant side effects, such as back pain and upset stomach.
  • Is only attainable through a doctor's prescription.


For those dieting to improve their health and lower the risk of developing heart disease, sometimes drugs are an appropriate measure to help lower those levels. Lovaza is an FDA-approved drug that is medically approved to treat high triglyceride levels (a leading cause of heart disease), but it may not be appropriate for all dieters, due to its side effects and negative interaction with some conditions.

  • What are the side effects?

    side effects please

    • Maribel (Editor)

      Hello. All users are different and can experience different side effects; please make sure to consult with your physician before taking this product.

  • You are absolutely right.

    You are absolutely right. Omega 3 from fish oil contains trace mercury which is remarkably toxic. Hemp or flaxseed
    (linseed ) oil is the safe way to get your omega 3. As an aside, the AMS is absolutely wrong about the benefits of omega 3.

  • Can it cause diabets?
    TT (Verified User)

  •  This product worked for me
    beachnut (Verified User)

    I had taken Lovaza in the past, not for weight loss, but to lower my triglicerides. They went from 243 to 167, my HDL also rose a few points from 39 to 42. Because of the cost and after thinking it was just fish oil, I went to using fish oil supplements (it looks like the same ingredients, but lower levels with the supplement). My triglicerides are back up to 254 and my HDL is down to 34! I have a call in to my Dr. to see if I should go back on Lovaza.
