Named in 2018 as the super probiotic of the year, Lactobacillus Plantarum is a probiotic every single human needs for optimal health. I recommend ProBiotixx+ for its amazing therapeutic healing capacity. For a lot of my patients who are gassy, experience an assortment of IBS symptoms, have extreme degrees of constipation or diarrhea, and who notice changes in mood and weight after consuming certain foods find a powerful impact from adding Lactobacillus into their wellness programs. I’ve even seen patients who do not experience gut imbalances receive healing benefits like better mental focus, improved sleep, and even lowered stress hormone levels.

Not only is the bacteria strain antimicrobial, but it’s listed as a class of psychobiotics. The true power of ProBiotixx+ is that it can help balance the gut/brain connection. Particularly, research shows certain probiotics like Lactobacillus Plantarum can balance our neurotransmitter health, bringing calm to the brain, easing depression, promoting sleep and an overall sense of peace to our central nervous system.

Lactobacillus Plantarum

Lactobacillus Plantarum

A common beneficial bacteria found in cultured vegetables, this hardy probiotic can withstand temperatures between 1-60°C (33-140°F). It has the ability to adhere to the sides of the intestines, creating a healthy barrier in the colon and is resistant to most commonly prescribed antibiotics.

3rd-Party Tested & Verified

Organixx pays to have all our products tested by NSF (an internationally recognized leader in independent product testing) and other highly reputable third-party testing labs. These third-party laboratories test for glyphosate (the active ingredient in Roundup), GMOs, pesticides, herbicides, insecticides, and heavy metals. We're proud to be one of the few (if not the only) supplement companies to openly and honestly share all of the test results on our website.

Proteolysis is the breakdown of proteins into smaller polypeptides or amino acids. So, when we say this is a “proteolytic probiotic” it means it is a proven, patented strain that has the ability to not only eliminate bad bacteria, but also to break down carbs and protein.
ProBiotixx+ is a single-strain probiotic. It contains 2,500,000,000 (2.5 billion) CFU of Lactobacillus plantarum OM per capsule.
Patent # 5,895,758

Patent Abstract: The invention relates to a biologically pure strain of L. plantarum, L. plantarum, OM. The L. plantarum, OM strain has proteolytic, anti-viral, anti-retroviral, anti-bacterial, anti-microbial, and anti-tumoral characteristics and uses. Thus, the invention relates to agents having proteolytic, anti-viral, anti-retroviral, anti-bacterial, anti-microbial, and anti-tumoral agents, having the respective capabilities. With respect to its anti-viral capability, the provided strain includes the capacity to screen a pharmaceutical agent to determine whether the pharmaceutical agent has any anti-retrovirus activity. The invention also relates to a nutritional supplement having proteolytic activity and utilizing the L. plantarum, OM ATCC 55981 strain.
While many probiotic formulas boast about high CFU, what actually matters most is how FAST they multiply.

ProBiotixx+ doubles every 20 minutes once it makes contact with the foods in your stomach. It continues to multiply until the “bad bacteria” are dead and out of your system in just 3-4 days.

It starts at 2,500,000,000 (2.5 billion) CFU but within 20 minutes has doubled to 5,000,000,000 (5 billion) CFU. Imagine how many CFUs there are within a few hours! For this reason, ProBiotixx+ can be manufactured to a lower starting CFU count while ultimately being more effective.
Freeze-drying is the most commonly used form of dehydration when manufacturing probiotics. This method was first used to preserve medical supplies and is now widely used in preserving probiotics. Very simply, the freeze-drying process stabilizes the product, concentrates large quantities into smaller units which in turn increases its potency, and lastly, puts it into a state that doesn’t require refrigeration.
Organixx ProBiotixx+ is shelf stable and does not need to be stored in the refrigerator. For best results, you can store the products in a clean, dry, and cool area such as a closet or cupboard.
Organixx ProBiotixx+ is vegetarian but may not be considered vegan. It’s grown on a dairy-based medium which makes it much stronger, but the end product does NOT contain dairy. Based on this information you will need to determine for yourself if this product is appropriate for you or not.
Yes, all Organixx capsules can be opened and the powder added to food or beverages.
While it should be safe to do so, please always consult with your physician before giving any supplements to children and to determine the recommended dosage.
ProBiotixx+ is egg-free, shellfish-free, nut-free, and yeast-free. There are no gluten-containing ingredients used in this product.

Regarding dairy, it is grown on a dairy-based medium which makes it far stronger, however the end product does not contain any dairy.

Good prodct

My reason for only four stars is that you have to take multiple pills a couple time per day for optimal results. Otherwise it's a great product.

Todd Dell

Good, nothing dramatically different. Always good to have a capsulized probiotic for travel. I still favor kim chi when I have refrigeration.

Farm to Bottle Ingredients

The majority of daily vitamins and supplements on the market are made with synthetic ingredients, as well as fillers, binders, coloring, flavorings, preservatives, and other artificial ingredients that your body has a hard time recognizing. At Organixx, we're proud to offer the absolute best nutritional formulas that help people get and stay healthy. Our products are made with REAL plants and whole FOODS that your body already knows how to assimilate and use to the greatest advantage for your health.

People Over Profits

We believe in doing things differently. While most supplement companies spend the majority of their money on advertising, we spend ours on the highest-quality, clean, and non-GMO ingredients available – certified organic, whenever possible. In fact, we spend on average 400% (4 times) more to manufacture our products because of our certified organic ingredients and time-consuming fermentation and sprouting processes that increase bioavailability. In the end, you get exactly what you pay for – the best supplements on the market.

Maximum Nutrition

Many of our supplements and their ingredients  are sprouted and/or fermented as part of the production process. You've likely heard about the gut health benefits of eating fermented foods. But did you know that fermentation also helps enhance the vitamin and mineral content of whatever's being fermented? It's a form of pre-digestion which means your body can absorb even more of the “good stuff” in the supplements.

Farm to Bottle Ingredients

More Bang for Your Buck

While our supplements might cost a little more, in the end, you save more. We focus on formulating synergistic BLENDS that address specific health needs. We start by researching the best and most effective synergistic combinations and then we source the cleanest, highest-quality ingredients available. You get the results you're looking for without the expense and hassle of buying dozens of supplements and swallowing handfuls of pills every day. It's a win-win for everyone.
