What are CFUs and how many do you need?

When comparing probiotics, there are two items on the label that are crucial: the type of probiotic strain and the number of colony-forming units (CFUs) contained. You already know that Culturelle® contains 100% of the most clinically-studied probiotic strain, Lactobacillus rhamnosus GG.†† Now it’s time to get into the details of just how much of the Lactobacillus rhamnosus GG you can expect to get in each serving of Culturelle®, and why it’s so important.

CFUs explained

As mentioned, CFU stands for colony-forming unit, which simply refers to the number of live and active micro-organisms that can be found in each serving of the probiotic you are taking. When you take Culturelle®, the Lactobacillus rhamnosus GG will begin to colonise the good bacteria in your digestive tract, which is why they are referred to as colony-forming units.*

It’s all in the numbers

The number of CFUs within the product can play a big part in how effective the probiotic is that you are consuming. Now here is where it gets complicated. Not all probiotics tell you how many CFUs you are receiving per strain, and the ones that do might not have science to back it up. With Culturelle®, it’s different. Culturelle® formulations are based on science, with just the right amount of live active cultures to support the unique benefits of each product.

Why you can trust Culturelle®

There’s one more factor to consider: do the number of CFUs promised to you on the label equate to the same number you will receive when you take the probiotic? With Culturelle® the answer is always yes. But with a lot of other probiotics, they merely state the number of CFUs used during manufacturing. Since probiotics are living micro-organisms – and sensitive ones at that – they can perish pretty easily. Heat, moisture, light, and air can all make their lives come to a screeching halt, and if they aren’t alive when you consume them, they won’t be doing any colonising in your digestive tract.

Thanks to our unique, state-of-the-art manufacturing process and packaging, we are able to guarantee that the number of naturally sourced, live Lactobacillus rhamnosus GG cultures stated on the pack are the same as the number that will make it to your intestinal tract. This is true as long as the expiration date has not passed. You don’t even have to store them in the fridge for them to maintain the strength of the CFUs (simply ensure they are kept in a dry place that maintains room temperature or below).

Remember, when you want to achieve the immune and digestive health benefits that probiotics can provide, you need to ensure that you have the appropriate number of a proven strain. Culturelle® is the proven probiotic with Lactobacillus rhamnosus GG that can offer you both.*
