Are you thinking about trying a probiotic supplement to reduce any digestive symptoms you might have? Here’s a guide on how to choose the best probiotic for you that works!


3 Steps To Choosing An Effective Probiotic


Step 1: Find Out the Strains It Contains


When you look at the back of a probiotic label, there should be a list of which probiotics are in the supplement. If there is a claim of 10 billion bacteria per serve, but no list of which strains or species are in the product, avoid it! You don’t know what you’ll really be getting.


Probiotic Names


Genus? Species? Strain? What does it all mean? Here’s a quick run-down:

Genus = a certain subgroup of bacteria. e.g. Bifidobacteria or Lactobacilli.

Species = the next subgroup after the Genus is established e.g. Lactobacillus rhamnosus.

Strain = a differentiation between different bacteria within the same subgroup of species. e.g. Lactobacillus rhamnosus Gr-1 vs Lactobacillus rhamnosus LGG.

The bits you’re looking for are those letters and numbers on the end, there – Lactobacillus rhamnosus LGG. The important part is the LGG – it tells you that this is strain-specific and you will know exactly what you’re getting.

Step 2: Choose Strains With The Right Evidence


There is so much research out there on probiotics and what they might do for your health! It’s confusing!


How To Know If This Is The Right Evidence


Check If It’s Been Tested On Humans


All research on probiotics is done on animals, just like with medications and herbs. The next stage is to then test these in humans. What happens, though, is that some probiotic strains are taken to market with no human trials done first.

It isn’t known whether the animal trials will translate to humans without testing them in humans.

It’s important to know that the strain you’re taking was trialled in humans. If it’s only tested on animals, that’s not how to choose the best probiotic for you (or any human)!


Check If It’s Proven To Work For Your Condition


Digestive symptoms can be so individual and unique. It’s essential that the probiotic you choose is going to actually address your symptoms. Throw any old strain in to see what sticks and you’ll be wasting time and money with this approach!

Make sure your probiotic is actually trialled in humans for the condition or symptom you’re experiencing. Then, you can take the plunge and pick up your probiotic.


Step 3: Take A Therapeutic Dose


There’s no use in taking a probiotic as medicine if there isn’t a high enough dose!


Dosing: A Guide


General Rules


As a rule of thumb, bacterial strains need to be dosed at 1 billion CFU (Colony Forming Units) per day for a proper effect.

There are some exceptions to this rule. I recommend much higher doses for clients who have certain needs (sometimes hundreds of billions are needed over short periods). There are also times when the dosage needs to start below that 1 billion CFU mark and increased slowly over time.


Working Through The Confusion


A strain-specific probiotic prescription will almost always form part of a treatment plan for patients of mine.

Doing the above will be a lot of hard work (and believe me, reading through the research is tough enough with a Bachelor Degree in Health Science!) don’t worry, I’ve got you covered!
