Can You Overdose on Probiotics + Other Common Myths

Debunking probiotic myths to give you all the facts

A lot of people have questions about probiotics… and a lot of the information floating around the web is just wrong.

What they do get right is that taking probiotics can benefit your overall health, from immunity to sleep to weight management.

We’ll take a look at some common myths and get to the truth, so you can get the most out of your probiotics.

5 Probiotic Myths Debunked 

Let's sort out the misconceptions from the facts! Here are the 5 most common myths and questions we see all the time about probiotics.

1. Can you overdose on probiotics?

No, you can’t overdose on probiotics. These beneficial bacteria have been studied extensively for safety and effectiveness for decades… even at what would be considered mega-high doses.[1,2]

Supplements typically contain billions of probiotics. Your gut microbiome contains trillions of bacteria.[3] So even if you accidentally took extra probiotic capsules, it would still represent only a small portion of the total bacteria in your system. If you take too high of a dose than what your body is used to, you might experience some stomach upset like gas and bloating (a common die-off reaction), but you can’t actually overdose on probiotics.

2. Do you need to switch up probiotic strains so they don’t become ineffective?

No, you don’t need to change up your probiotic strains. However it is important you are taking the right strains—specifically, spore-based probiotics—to truly see a difference in your health.

These probiotics work by adding beneficial bacteria to your gut microbiome, which helps to crowd out pathogens and support the strains that naturally live in your gut. The probiotic strains inside the capsules aren’t generally the same as the native strains in your gut,[4] but the probiotics you take do play a very important role in helping those native bacteria grow and flourish.

When you take spore probiotics, you can take the same probiotic supplement for years, and it will work as effectively as it did in the beginning. But this is not true for the majority of other probiotics, which probably explains how this myth got started.

3. A probiotic made me feel worse so does that mean it isn’t working?

No, experiencing symptoms like gas, bloating, and diarrhea can actually indicate that your probiotic is working!

Your symptoms are probably being caused by pathogens as they die off. That’s a sure sign that your probiotics are working exactly the way you want them to. Reducing pathogenic populations is part of their job, clearing space for more native beneficial bacteria to multiply. So while the die-off process can feel not so great—temporarily—it’s actually a good thing. 

That doesn’t mean you have to suffer through it. You can keep making forward progress and minimize die-off symptoms by lowering your dose. Then gradually work back up to the full dose as the die-off symptoms fade away.

Using a product like Just Thrive Probiotic Gummies can be helpful in these extreme cases. They’re easy to divide, making it easier for you to lower your dose consistently and confidently. Plus they’re already a lower dose than the probiotic capsules. You can start with 1/4 gummy, then move up to 1/2, and finally take the full dose.

4. Should I stop taking probiotics when I’m on antibiotics?

No, it’s extra important to take probiotics when you’re on a course of antibiotics.

Antibiotics kill off both harmful pathogens and beneficial probiotic bacteria. That leaves your gut microbiome more vulnerable to an imbalance called dysbiosis, where pathogens begin to outnumber probiotic bacteria. And antibiotic-induced dysbiosis can lead to significant health issues if it’s not dealt with quickly.[5,6,7]

Taking probiotics can help offset the negative effects of antibiotics without reducing their effectiveness against pathogens.[8] You can take probiotics throughout your entire course of antibiotics. Some special spore probiotic strains, like Bacillus clausii, work particularly well in this situation. In fact, Bacillus clausii resists even the use of multiple antibiotics to help safeguard against antibiotic-associated diarrhea.[9]

5. Do probiotics only affect my gut health?

No, probiotics have whole-body health benefits… though those do start in your gut. That’s because your gut microbiome is your body’s wellness center. Up to 80% of your immune cells are in your gut.[10] And that’s just the starting point for probiotic advantages.

Research shows that probiotics can have a positive effect on:

  • Heart health[11]
  • Liver health[12]
  • Blood pressure[13]
  • Blood sugar[14]
  • Mood[15]
  • Joint comfort[16]
  • Attention and focus[17]

Bottom line: Taking probiotics is one of the best things you can do to keep yourself healthy. That’s a fact.
