How Do Probiotics Work?

About 60-70% of your body’s immune system is located in your gastrointestinal (GI) tract – to help prevent molds, viruses, and other harmful substances from gaining access to your body. Your GI tract naturally contains both “good” bacteria (known as probiotics or microflora) and “bad” bacteria. Researchers recommend that you maintain a healthy ratio of approximately 85% good bacteria to 15% bad bacteria.

Probiotics are Good Bacteria

Probiotics inhibit the growth of bad bacteria, promote good digestion, reduce toxins, and boost your immune system. So keeping a ratio of many more good bacteria to bad bacteria is crucial to staying healthy.

So how can you get more good bacteria into your GI system? You can get them by eating certain foods, or by taking probiotic supplements like Probonix.

When you take a probiotic supplement, millions of bacterial cultures (often referred to as CFUs – colony forming units) are swallowed and enter your stomach. This is where it gets tough, and where the effective probiotics are separated from the weak.

How Probiotics Work

Testing the efficacy of probiotics is a complex and pricy process, but we were so confident in our formulation and its ability to deliver live CFUs through to the intestinal tract that we couldn’t wait to test Probonix against other leading probiotics.

How Probiotics Work - Probonix 2 months, Probonix 1 month, Children's Probiotic, Women's Weight Loss Formula

Probonix is currently one of the only scientifically-tested supplement proven to deliver a maximum effective dose of live bacteria into the GI tract. This is because the medical team at Humarian has developed a breakthrough technology in which they protect the bacteria cultures in an acid coating which ensures that a much higher percentage survives the harsh stomach environment.

Our organic, non-GMO liquid probiotic uses an exclusive formula of 12 of the most effective probiotic strains for supporting general gut health.

It can help ailments like:

  • Gas & bloating
  • Diarrhea
  • Irritable Bowel Syndrome (IBS)
  • Lactose intolerance
  • Dental health issues
  • Allergies
  • Eczema
  • And more!

What Others Are Saying 


I’ve been using this product for about 3 years and I’m very, very pleased with the results. I had abdominal issues that were misdiagnosed. When I started Probonix, the problems went away. That was completely unexpected. I wasn’t taking it for that reason and I had tried 2 other probiotic brands before. I suppose they worked okay, but Probonix is the one that gave me the most benefits. I will continue to use it as long as it’s available.


Love the ease of use! Two drops, twice a day – easy travel size, no refrigeration and makes a huge difference in my digestion. It was recommend by my Functional MD and I’ve not found anything better on the market.


I got my life back! I have suffered, and I do mean suffered from Lupus for 12 years. My doctor recommended that I use this probiotic as it brings balance to an out of control immune system…Fatigue Gone! I am doing things I have not been able to do for years. I am so thankful that finally, something has helped and I feel like my old self again. I whole-heartedly recommend this product.

Can Probiotics Help Infants with Colic?

Can Probiotics Help Infants with Colic?

Between changing diapers, constant feeding, doctor visits, erratic sleep schedules, exhaustion, and just generally learning how to care for an infant, new parents have plenty to worry about in the first few months after birth. Unfortunately, about 25% of parents also have to deal with infant colic, a common gastrointestinal disorder that occurs in newborns one to three months old and leads to prolonged and often intense crying. These crying sessions can often last for hours. Colic can be particularly stressful for parents because it happens for seemingly no particular reason in babies that are otherwise completely healthy. Colic has been associated with postpartum depression, self-doubt in parental ability, sleep deprivation, and much more. The colic is temporary, but its effects can be long-lasting for parents that are not properly prepared.

Getting cool stuff is the essence of happy holidays, right? Those far wiser than I would say no, it’s giving that’s key to happiness. Your eyes might have instinctively rolled to the back of your head after reading that, but what if I told you that science agrees?

In an effort to simplify our product offerings, Humarian will be discontinuing our adult 2-month varieties.
