If you haven’t looked carefully at Lovaza, now’s your chance. Here at DietSpotlight, we conducted an in-depth review, focusing closely on the ingredients, side effects, level of customer service and scientific research. We also sorted through countless user comments and remarks that are posted on the web. At this point, we summarized and compacted all of the facts and feedback to give you the important details.

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.

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.

Previous Lovaza Review (Updated September 20, 2013):

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.

Lovaza Side Effects:

Our look into Lovaza was detailed, but we felt the need to go even deeper so we chose to take a gander at Lovaza side effects. We searched for clinical information to see what dieters can expect from the medication. We also read through experiences. Then, we took the facts and condensed them to give you the bottom line.

What You Need to Know

First off, Lovaza is a prescription omega 3 fatty acid medication. You take four grams each day at a single time or divided between two doses. The result is supposed to be lower triglyceride levels. You can take the pills with you, if necessary.

The medication, sold by GlaxoSmithKline, is nothing more than an EPA and DHA product, which can be all natural. Only pharmacies sell it and you will need a prescription from your doctor. We like that some patients have reported positive results and insurance may cover it, but read on…

Joint Pain – “Ouch!”

Our first issue with Lovaza side effects was joint pain. “You are taking omega 3 to improve health, not create another problem,” says our Research Editor. “If you have any troubles like those described by some dieters, that may be enough to ask for a different medication.”

“Joint pain in knees and hips, muscle pain in legs, shins, sometimes excruciating,” one patient explains.

Another offers, “I am having joint pains to the point that I can hardly walk.”

Stomach Distress

We also found mention of some stomach issues that came up time and again. “Bad aftertaste, belching up fishy smell/taste, heartburn, gas.. I’d rather have the high tri’s!,” one user explains.

“I have taken this medicine 3 days. I’ve had chronic burping, nausea, vomiting, diaherea, stomach pain, light headness, headache, body chills, tireness and sleepness,” offers another patient.

Sometimes the reactions were a little scary, “I have SEVERE lower Abdominal pain and haven’t slept in 2 days. Diahrea(sp) for the whole time.”

Our research has connected small issues, like joint pain, with reduced chances of long-term success. If Lovaza side effects are enough to cause the dieter to question it that could be an issue to discuss with the physician.

The Science

The FDA has to approve all prescription medications, so there are many clinical trials into this one. The research has also mentioned potential Lovaza side effects. According to the product insert, proven reactions include constipation, rash, vomiting, gastrointestinal disorder and taste perversion. We found absolutely no connection with weight-loss. At DietSpotlight it is very important that we find support. If the dieter needs to take a different road to lose, that’s may be a better option.

The Bottom Line

We’re always up for a closer look at a medication – in this case Lovaza side effects. We found some positive results where patient triglyceride levels did drop, but we can’t recommend it because there’s absolutely no connection with weight-loss. We also have issue with the adverse reactions, like joint pain, reported by some users.

If you want an effective weight-loss solution, we suggest going with a supplement that’s been clinically tested and proven to help you lose more. One that doesn’t come with the risk of negative reactions.

Among the best supplements we’ve reviewed this year is Dietspotlight Burn. We found clinical research supporting the four-ingredient proprietary blend showing it helps spark metabolism and promote fat loss. There are no reports of harmful side effects and dieters are talking about seeing some amazing results.

Plus, the company that offers Dietspotlight Burn is confident in the supplement, so they’re offering a Special Trial Offer, which is quite impressive.

  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?

  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.
