Dr. Mercola Review - Do These Health Supplements Really Work?


You may be surprised by what I say in this Dr. Mercola review. We dug deep, focusing on the ingredients, side effects, scientific research and customer-service quality. Then we scoured the web for user comments and remarks. At this point, we compacted all of the facts and feedback we discovered in order to give you the information you need.

What is the Dr. Mercola Diet?

First off, Dr. Mercola offers a collection of diet products aimed at supporting health, wellness and weight-loss. Ingredients include magnesium l-threonate, krill oil, whey protein concentrate, evening primrose oil, curcumin, and various vitamins and minerals. He is both a doctor and author who focuses on health and alternative medicine. Aside from books and DVDs, he also offers various supplements. These fall into categories such as antioxidants, immune support, digestive health, probiotics, enzymes, and multivitamins. All of these products are available directly from the official website.

Judging from the company website, Dr. Mercola products have been available since 1997. There are also products for kids, pets and home and garden. A return policy is provided on the website, but all bottles must be unopened and unused. On a side note, no GMOs are used in these formulas, but read on…

Products Similar to Dr. Mercola

Unpleasant Taste – “Something To Consider?”

The first thing we noticed about some formulas is that the flavor is not well received. According to our Research Editor, “There are some customer complaints regarding the taste of Dr. Mercola Miracle Whey protein powder. This is certainly something to consider. After all, you must be able to drink the product if you want to see actual results.”

One person commented, “Tried the Dr. Mercola Miracle Whey, but this protein powder tastes really bad.”

However, not all users complained. In fact, one individual said, “The taste is pretty good. I got the banana flavor.”

Another reported, “The powder does mix very well, and can be mixed in a cup shaker easily. It’s also tolerable with water, but tastes rather bland.”

Customer Complaints About Dr. Mercola – “Yikes”

If you take a look at dealer websites like Amazon, you will find a number of discouraging user comments for Dr. Mercola supplements. For instance, one person mentioned, “Made me uncomfortably gassy. Others I have tried have not. Was also more expensive. Not worth it.”

On the other hand, a different customer said, “I did not experience any Dr. Mercola side effects, but it’s clear to me that more affordable supplements are out there.”

“I’ve been taking the Dr. Mercola Krill Oil. It’s decent so far. Seems to help with PMS symptoms,” revealed another.

Our research has revealed that if there’s a particular aspect of a health supplement or weight-loss product that is quite problematic (unpleasant taste, customer complaints, high cost) the odds of real results for the long haul are slim. In other words, if Dr. Mercola products do in fact lead to all sorts of discouraging user comments, this could be a deal breaker.

The Science – “Is It There?”

Well, Dr. Mercola himself has an extensive education in the medical field. Therefore he certainly has some knowledge when it comes to health and wellness. However, we did not find any direct link between his supplements and weight-loss. For us at DietSpotlight, we like to see some documented research that ties the product to weight reduction before we get behind it.

The Bottom Line – Do Dr. Mercola Products Work?

Now, here is the bottom line on the Dr. Mercola diet. We like that this individual has an extensive medical education. It’s also nice to see that all of his books and supplements are available on the web. However, we have some reservations about these products after reading discouraging customer comments that are posted online. Furthermore, it does not look like Dr. Mercola focuses specifically on weight-loss.

If you’re actually interested in shedding excess pounds, then we advise you to go with a product that is backed by published science, does not have an unpleasant taste, is easy to use anywhere and gives you plenty of bang for your buck.

Among the best products we’ve seen this year is one called Dietspotlight Burn. Its formula includes four key ingredients that have been shown to help elevate metabolism and increase fat loss. We can’t find any negative remarks from customers, and comments around the web show people are seeing solid results.

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

Dr. Mercola Products - What You Should Know

Dr. Mercola is the author of the controversial book The No Grain Diet and is known to practice some rather extreme forms of alternative medicine when it comes to health and dieting. He is a vocal opponent of many vaccinations and also of the Food and Drug Administration. In their turn, the FDA have issued warnings for violations regarding marketing practices when it comes to nutritional products, many of which Dr. Mercola sells on his website. His line of products include Astaxanthin, Krill Oil, Probiotics, Pro Puffs, Pure Powder Protein Powder, Cassava Bars, Coconut Oil, Vegan Chocolate Bars, Fermented Ginger, and more are offered on his main website.

Dr. Joseph Mercola does encourage improved health (though there is some disagreement over whether or not his diet is actually safe) through diet, and he recommends very specific foods and combinations of food in order to achieve the result of a healthier lifestyle. While he criticizes many drugs that are put out by popular drug manufacturers he is also quick to promote certain dietary supplements. Among those supplements are Vitamins D and K, probiotics, krill oil, fish oil, and anti-oxidant supplements. In addition, Dr. Mercola has also endorsed similar sibling products like fermented black garlic, krill oil for women, vegan protein powder and blood pressure support.

Dr. Mercola - A List of Ingredients

This is a diet plan that encourages the use of many supplements. Specifically, unprocessed, unrefined or non-homogonized foods that are believed to be beneficial to overall health, exercise, Omega-3 fats, fish oils. Dr. Mercola also recomends drinking filtered water in addition to mental health and emotional release exercises.

Product Features With Dr. Mercola

Dr. Joseph Mercola is an enthusiastic supporter of alternative medicine and treatment options. Some of the techniques he embraces include acupressure, naturapathy, metabolic typing, and Traditional Chinese medicine. He maintains that the medical industry is flawed and has strayed from its intended path as a result of "contamination by the pharmaceutical industry." Mercola's fans claim that he has a good deal of support in these claims. It's worth pointing out that you do not have to subscribe to the entire package in order to derive benefits from some of what Dr. Mercola has to offer.


  • Encourages personal responsibility.
  • Promotes healthy living, physical activity, mental and spiritual well-being.
  • Provides a complete weight loss solution rather than only addressing one issue.


  • Encourages the elimination of all grains and in some people this could be nutritionally harmful.
  • Dr. Mercola has been warned about advertising practices by the FDA.
  • A highly controversial approach to medicine and health.
  • Dr. Mercola has been dismissive of many traditional health concerns that may lead to serious consequences.
  • This diet could be difficult for some users to follow, since it involves cutting out staple foods.
  • Generally, this is more of a holistic health regimen than a diet specifically devised for weight loss.


Dr. Mercola is viewed by many as a paragon of virtue and by others as a textbook snake oil salesman. You will need to decide for yourself if his off-the-wall approach to health and diet is something you want to consider when your life and health are on the line. He offers some advice that is quite sound and seems very scientifically reasoned, and other advice and guidance that may seem to come from pretty far in left field.

You do not have to take an 'all or nothing' approach to the diet plan that Dr. Mercola presents. This means that you can introduce the positive aspects of his plan: exercise, sleep, emotional release, and even some of his dietary suggestions without giving up all grains and accepting the potential health risks that may result from this sacrifice, or turning your back completely on modern medicine. If you decide to see how Dr. Mercola probiotics can assist you in your dietary needs we recommend that you proceed with caution.

    What natural ways can a person reduce body fat including medications and surgical process?

  •  You should be ashamed
    Catharine Keel (Verified User)

    Dr. Mercola,

    My husband ordered me one of your tanning / vitamin D beds as a gift for Christmas. He ordered the wrong one and it was delivered without my signature or knowledge by UPS, even though it says very clearly on the box that it must be fully inspected before the delivery driver can leave it. When I contacted your company to exchange it for the correct ($1,700) machine (which I would have sent back at delivery if the driver had rang the door bell to let me inspect the delivery)I was offered absolutely no help with the return. In fact I had to borrow a neighbors truck to get it to a UPS store and was then charged $177 to return it because your company wouldn’t do anything to help (i.e. use your reduced UPS tariffs, order a UPS pick up…). In fact, I was planning on simply exchanging the bed for the correct one but was never even given that option. I have spoken to 4 of your customer service reps and supervisors and was told that not only would you not discount anything to offset the nearly $200 shipping charge, your company has also charged me a 15% restocking fee. Dr. Mercola, apparently the economy hasn’t affected you like it has the rest of the world and you can afford to lose a sale of this magnitude. My mother has been a customer of yours for years as well and at this point neither of us will ever give your company business again. I have never experienced such a horrendous display of non-customer service. I am disgusted with this treatment and you should be ashamed.

  • acknowledgement of the claims
    Remy Francisco

    Dr. Mercola,
    I have read your article regarding EMF. I just came across a product called Quantum Pendant from InfusionExcel which accordingly helps block EMF. I’m using it and it seems to be working I’ve also heard several testimonials regarding it’s benefits. Would you mind taking a look at it and advise me if the claims are true? Appreciate whatever information you can provide. Thank you.
