What is a Probiotic?

Did you know the human body has more bacterial cells than human cells? It might sound creepy, but roughly 100 trillion microorganisms call your body home and play a vital role in your immune function, gut health, and more. These specific strains are necessary to keep you in good health in different ways. The delicate ecosystem of probiotic strains and doses in your body is complex. Read along as we provide enough evidence on the benefits of probiotics and why you should consider adding this supplement to your daily vitamin package.
Probiotics are beneficial bacteria that reside symbiotically on and in the human body. The gastrointestinal tract, in particular, contains trillions of live probiotic bacteria known as the gut microbiome. These particular strains of good bacteria create a bacterial balance throughout your body to help with immune health and digestive problems.
You can get your probiotic strains in a number of ways through specific probiotic foods. A fermented food source or drink options like sauerkraut, kimchi, yogurt, kombucha, kefir, and miso introduce probiotic bacteria to your digestive tract and cultivate a healthy microbiome. Additionally, eating the right amounts of plant foods provides fiber from prebiotics to feed the bacteria and encourage proliferation and diversity.

Your digestive system needs these different strains of probiotics to work well, but you may not always get the proper dosage through a healthy diet alone. In these cases, you may get the best results when you rely on dietary supplements to provide a higher dose of the best probiotics and other important nutrients.

How Probiotic Works

A healthy balance of friendly bacteria helps to synthesize nutrients like folate, vitamin B2, vitamin B12, and vitamin K2. These little live bacteria also break down food to support digestion and gut function. This can help in very specific areas of your digestive health. For example, a 2016 clinical trial in the Nutrition Journal found that a Lactobacillus acidophilus supplement alleviated symptoms of lactose intolerance by breaking down the lactose sugars found in dairy products (1).
Probiotics ferment indigestible carbohydrates and fiber in the digestive tract to produce lactic acid and short-chain fatty acids (SCFAs) like acetate and butyrate. These compounds aid gut health by providing energy, restoring gut barrier function, soothing inflammation, and creating an acidic environment that kills harmful pathogens.
The trillions of probiotics in the microbiome also help to regulate mood and support brain health via the enteric nervous system (ENS) (2). Millions of nerves connect the gut and the brain, allowing them to communicate and influence each other. Having good bacteria and live microorganisms to regulate any imbalance of harmful bacteria can offer beneficial effects for specific functions of your brain and overall gut health.

What Harms Probiotic Bacteria? Deficiency of Probiotic Products

Unfortunately, there are a lot of specific health concerns and lifestyle habits that can impact your probiotic levels. Your gut health, immune function, and digestive tract may be affected by an excess of processed foods, a low-fiber diet, stress, aging, smoking, pollution, and an overuse of antibiotics. This can leave your gut without probiotic products and have negative side effects. Any reduction in microbial diversity can cause the following specific health issues:

  • Inflammation
  • Digestive symptoms
  • Poor immunity
  • Allergies
  • Skin issues
  • Weight gain/obesity
  • Depression

Fortunately, probiotic supplements—containing the most beneficial Lactobacillus and Bifidobacterium strains—could repopulate your gut microbiome and support overall health (3). Our unique VitaRx Probiotic Formula provides capsule blends of 10 probiotic bacterial strains along with the prebiotic fiber, fructooligosaccharides (FOS). This is the best probiotic to feed healthy live bacteria and encourages their proliferation once they reach your digestive system.

Health Benefits

The effects of probiotics are numerous. Taking a dietary tablet a day can help you get the strains of bacteria you need in the proper dosage. Thanks to probiotic research and clinical studies, you can see a significant difference as well as the beneficial effects of various probiotics. Let's take an in-depth look at the health benefits of consuming the best probiotics for you.

Healthy Digestion

As the cornerstone of digestive wellness in healthy adults, maintaining a balanced gut microbiome may reduce digestive symptoms like cramps, gas, constipation, diarrhea, and inflammatory bowel disease. Clinical studies show supplementing with a probiotic could help those dealing with the negative digestive side effects of antibiotic use (4).
A 2019 systematic review analyzed the effects of probiotic supplements on those with Irritable Bowel Syndrome (IBS). It showed probiotics containing various strains of beneficial bacteria may significantly improve IBS symptoms when taken over a two-month period (5). Another systematic review found probiotic supplements effectively reduced symptoms of inflammatory conditions like Crohn's disease and ulcerative colitis (6).

Even if you aren't dealing with a serious medical condition, you can still enjoy the positive effects of probiotics. Check out a great option to get the right types of bacteria in supplement form so your gastrointestinal tract is prepared to handle any digestive function without any issues. After all, isn't everyone looking for a good option and best practice for healthy bowel movements and fewer tummy troubles?

Strong Immunity

The gut microbiome is the immune system's first line of defense—roughly 70% of your immune system lies in the intestinal tract! Your gut microbiome is constantly working to keep harmful, live microorganisms and bad bacteria at bay so you don't get sick. Probiotic strains act as the body's defense to balance out bad bacteria and offer regularity to your microbiology.
A 2014 systematic review in the British Journal of Nutrition observed older people and young children taking the Lactobacillus and Bifidobacterium strains when they developed common respiratory infections. The healthcare providers found that adults and adolescents taking these dietary supplements had a shortened illness duration and had to take less time away from work or school (7).

Overall, these insights prove that probiotics can often act as medication to help your immune response get rid of harmful bacteria quickly. Even a capsule a day of this dietary supplement can help feel your best for a long time to come.

    Healthy Body Composition

    Poor gut microbiome diversity and dysbiosis have been associated with increased appetite and weight gain. When your bacteria are imbalanced, the body reacts to handle that inconsistency. Probiotic benefits can help you get back on track and enjoy better regulation.
    A study in the Journal of Nutritional Science found that supplementing with Bifidobacterium breve daily for one month significantly increased fat loss when compared to a placebo group (8). This is another good reason to try different probiotic strains in your vitamin routine.

    Regulates Mood

    Did you know 90% of the "happy hormone" serotonin is produced in the gut? Known as the “second brain”, the gut microbiome can support mental health by producing brain chemicals like serotonin via the gut-brain axis (9). A 2016 review study confirmed that taking probiotic supplements helped to reduce depression in both healthy people and those diagnosed with major depressive disorder (10). Feel your best physically and mentally with the best probiotic supplements.
