Dr. Mercola New Complete Probiotics • Review & Best Price

Updated May 2015.

I’ve tested many probiotics supplements before I decided to try Dr. Mercola New Complete Probiotics. Dr. Mercola’s enthusiasm for friendly bacteria and fermented foods is well known and his Complete Probiotics supplement has received much praise from many consumers.

In any case, I decided to thoroughly test Dr. Mercola Probiotics to determine the quality.

Dr. Mercola Probiotics features

It does not take much research to realize that Dr. Mercola sticks to the highest principles when producing his probiotic supplements; he has included the best and most potent ingredients and in large quantities.

The list of positive features is pretty impressive. Dr. Mercola Probiotics is backed by academic and scientific research including patents, trademarks, and awards. There are also independent lab tests done to show the high potency of Mercola Probiotics.

Brief summary of features:

  • Packs a minimum of 70-90 billion bacteria in one serving (2 capsules)
  • 10 bacteria strains; all researched and with well-known benefits
  • Contains a specific super-strain Lactobacillus acidophilus DDS-1
  • All bacteria are of human origins; no soil organisms (HSO)
  • Capsules are vegetable-based
  • Is stable at room temperature for at least 2 years
  • Non-dairy, free from soy, corn, wheat, and gluten, and is non-GMO
  • Is acid and bile resistant to survive the stomach and intestinal transit
  • Uses nitrogen packaging and is freeze-dried

Using Dr. Mercola Complete Probiotics

Mercola Complete Probiotics contains a high CFU count compared to many other probiotic supplements. Dr. Mercola also included an impressive number of different beneficial bacteria, including one that I had never tried before, Lactobacillus acidophilus DDS-1. (See end of post for details about this potent bacteria strain.)probiotic capsules in hand

At the time I did this test I had a very problematic gut so I was a good guinea pig.

I felt a positive effect just a few days after I started taking this supplement; the positive effect reached a maximum after about one month or two. One immediate effect was a much more stable gut, regular bowel movement and an overall pleasant feeling of comfort.

Amazingly, some of my most stubborn symptoms I’ve had for decades disappeared almost completely only after about a month. Symptoms like bloating, severe gut pain, inflammation, constipation and other symptoms that so often bothered me in the past disappeared almost entirely.

  • After using Dr. Mercola Probiotics for two years I concluded it was the best probiotic supplement I’ve ever tried.

The positive effects I experienced from using Mercola Probiotics were yet another good sign that this supplement contains a very successful combination of bacteria and in the right amount.

What about cost?

The recommended daily serving is two capsules. However, I noticed that after taking two capsules for some months, I was able to go down to one capsule per day and still get the desired effect. Then the price got even more attractive.dr mercola probiotics

I’ve also tried to take this supplement for a month or two and then stop for a month and then start again. This worked very well and significantly lowered the cost.

If you buy the larger bottle with 180 capsules, you’ll pay 40-45 cents per capsule (May 2015, Amazon,com). Considering the many health benefits, Mercola Probiotics can be a great investment.

Lactobacillus acidophilus DDS-1

Both Dr. Mercola Complete Probiotics and Probiotic Packs contain the unique bacteria Lactobacillus acidophilus DDS-1. Why is this noteworthy?
Lactobacillus acidophilus DDS-1 is a highly effective bacteria strain. There are other strains of Lactobacillus acidophilus out there, but without the extension DDS-1 specificity. The DDS-1 strain has unique properties.

Studies reveal that Lactobacillus acidophilus DDS-1…

  • adapts exceptionally well to the human body; it easily colonizes in the gut
  • is acid and bile resistant for intestinal survival
  • strongly promotes digestive health
  • supports the immune system
  • produces significant quantities of lactase, aiding lactose intolerant ones

Several studies have demonstrated the effectiveness of DDS-1 and validate its use as a probiotic.

Here are three studies:

  1. In 2010 a major health center conducted a review on DDS-1 and bowel health. After 60 days of treatment, most subjects showed significant improvement in abdominal health, bloating and occasional elimination irregularities.
  2. 2003: L. acidophilus DDS-1 support the epithelial cell lines
  3. 1997: In animal research, DDS-1 was shown to support the production of immune components. DDS-1 performed better than three other strains of Lactobacillus acidophilus and Bfidobacterium bifidum.

Final verdict

Mercola Complete Probiotic is a great supplement, highly recommended. The L. acidophilus DDS-1 in Mercola Probiotics seems to greatly enhance the effect of this supplement. Mercola Probiotics is suitable for most people no matter what the needs are.

    I’ve tried Dr Mercola’s probiotic supplement for some time now and I must say it’s even better than I expected. I’ve tried some other brands before and I felt a little better. But with this I first had a detox reaction with gas and skin rashes, a little scary. But it went away after a few days. My stomach feels much better and it seem the longer I eat this supplement the better I feel. But I wonder if I should take a probiotic supplement all the time? Can it be too much?

    Thanks for a great site

      Hi Perra:
      I’m happy to hear that the probiotic supplement works for you. Symptoms of detox can be varied and depends on a number of factors as amount of toxins, bad bacteria, and yeast you have in your body and how quickly your body gets rid of it. To ease symptoms just eat less probiotics. Usually a detox involves more that just taking a probiotic supplement; it involves making some dietary changes as well. For a good detox you should eat more raw food, drink more water, and include cilantro (tincture), garlic, MSM, parsil, chlorella in your diet and at the same time avoide sugar and carbs. You can also use infrared saunas and engage in intense exercise to promote an even more thorough detox. Just be aware that doing too much too fast can lead to a “healing crisis” where the detox symptoms can start to bother you too much. If they do, just slow down a little to give your body a chance to catch up.

      About your question if you can eat too much probiotics or for too long. Most research indicate that adding probiotics on a daily basis is exactly what most people need. Earlier generations ate probiotic food almost daily and in many parts of the world many still do. Sauerkraut, fermented vegetables, kimchi, fermented soybeans are eaten daily by millions without any negative side effects. In fact, those people who do include probiotics daily seem to enjoy better health. Probiotics daily keep your gut in balance, help combat virus, bacteria, and yeast infections. Beneficial bacteria train your immune system and create a perfect environment for your body to thrive. So the answer to your question is NO, you cannot eat probiotic for too long. However, people suffering from serious disease or who have a supressed immune system should consult with their physician before engaging in probiotics, detox or dramatically changing their diet.

    I am considering buying the pet version for my cat, but am concerned about the freeze dry process. Is this really as effective as the refrigerated probiotics? Does the fact that the pet version is in loose powder form and not in a capsule affect its ability to survive stomach acid. Thanks!

    • Ken says

      Hi Dave.

      This is a good question. It seems that freeze-dried probiotics may last longer than refrigerated or other powdered products. The probiotic powder product will not last as long if it is exposed to moisture as when the container is opened and closed. When composting probiotics for pets, certains strains a chosen that can survive the harsh stomach environment and reach the intestine. All dogs and cats can benefit a lot from probiotics. But they have slighty different needs, so you should get a supplement designed especially for cats. Fortiflora is a brand that seems to work well. Mercola’s Complete Probiotics for Pets is also very good, just a little more expensive.

      Yes, you can store it in the fridge if you like. But the advantage with Dr. Mercola’s Complete Probiotics (and others too) is that you don’t have to keep it cool. If you keep it in room temperature, it will still keep fresh for up to two years. This is very handy, especially if you’re traveling. However, if you live in a hot climate, you might want to put it in the fridge.

      Hi Kathy.

      Yes, no problem. Mixing probiotic supplements in smoothies does not harm the bacteria. You can mix it in most drinks, juices or smoothies. But hot drinks will not work as the heat will harm the beneficial bacteria. I regurlarly make my own probiotic drinks. I emtpy the probiotic capsule or pack together with some fruits, mix it and enjoy. If I add the probiotics to a vegetable drink then I will first run the vegetables through my juicer. After that I add one probiotic capsule into the juice, stir to dissolve the powder and I’m done.

  3. Victoria says almost 12 month old son got awful bacteria at 4month old and end up on antibiotics for 21 days.that together left him with a bad gut.i still breastfeed and he eats some fruits and veggies since he is 9 month old. But his solids comes out pretty much the way it goes pediatrician is not concern. But I am!very.i want him to get as much as possible from his healthy food and mommies milk.i tried probiotic(klaire labs) when he was 7 month old and that hurt his tummy almost instantly,after second day I stopped. I understand it’s part of the process (most likely) but I couldn’t explain that to my infant baby, and he can’t tell me how bad is the he is older (even thought still can’t talk) and I’m trying again.but giving him less then suggested. Today is 3th day and he developed a fever. I don’t know if it’s related (can it be?) but I’m home sitting mom and he doesn’t go public places.his stool looks the same so far. I worry. I feel like what if we have one of those rare cases where probiotic cause bacterial illness..should I continue? Also the brand you recommending it good for my baby AND me while I’m breastfeeding? What If I will take it all on me first, will my baby benefit enough thru my milk? And what do you think about the probiotic my son is taking. I’m sorry about many questions and my broken English. Thank you

      Hello Victoria.

      Sorry to hear about your son’s problems. But this often happens after taking antibiotics for so long, even if the antibiotics are needed. Sometimes a child’s body might repair a damaged gut by itself, but this is rare. More often they need help to rebuild the gut and intestine microflora.

      Probiotics can be a great way to do this, but it is not the only way. However, you need to do it right. Please check the post on probiotics and babies.

      Breastfeeding is very beneficial for the child’s gut. And even better if the mother takes a probiotic supplement as it will enrich the milk.

      Adding probiotics to the child’s diet should be done very slowly. Start off by dissolving a probiotic capsule in a glass of water or juice. Then feed your son a teaspoon once every hour or so until the glass is empty. If you son complains, then give him less, if no complaints, then you add a bit more. Slowly increasing the dose will avoid most symptoms.

      Add yogurt or kefir to the diet. Mix it with banana or other fruit and berries.

      If you’re into juicing, fresh juice can be a great way to rebuild a damaged gut. Juicing apples, pears, pineapple and mixing in a little vegetables can make it tasty even for children. Fresh juice is packed with vitamins, minerals and enzymes and it is easily digested and assimilated by the digestive tract. Smoothies are similar.

      About the best probiotic supplement. Dr. Mercola is very good and so is Bio-Kult.

      Be patient! It can take a long time to repair a damaged gut, but it can be done. Be persistent, stay positive and do your own research into this subject. This will boost your confidence and support your efforts.
