The Biggest Myth About Probiotic CFU Counts

In phrases of sustaining a probably the most nutritious consuming regime, the saying “the extra the merrier” can apply to stocking your fridge with a wide range of recent fruits and veggies, refilling your water bottle to satisfy your each day H2O wants, and feasting on fermented meals to assist your intestine and higher well being. However in the case of probiotic meals and dietary supplements, does the identical adage apply in the case of colony forming unit (CFU) counts?

To see what the true deal is regarding probiotic CFU counts and the way a lot they actually, effectively, rely within the common scheme of issues, we reached out to microbiologist Miguel Freitas, PhD, VP of Well being and Scientific Affairs at Danone North America.

First, what are CFUs?

CFUs are a unit of measure indicating the quantity of dwell and energetic organisms in probiotic meals and dietary supplements. “As a result of probiotics are microorganisms, you will see that values of CFUs are often within the order of billions per serving or billions per milliliter,” Dr. Freitas says. “The worth signifies the amount of microbes or cultures, however not essentially whether or not or not the micro organism offers a intestine well being profit.”

Is a better probiotic CFU rely at all times higher?

In a single phrase: nope. This reality would possibly come as a shock, particularly in mild of findings from an August 2021 Danone survey of 1,004 adults by which 59 % of respondents believed that extra CFUs in a given product yielded higher efficacy.

“It is a frequent false impression, however increased CFU counts aren’t essentially higher,” Dr. Freitas clarifies. What *is* higher, nevertheless, is a product that comprises “the particular pressure on the identical quantity as what was proven to be efficient in human research utilizing that product.” In essence, any probiotic meals or dietary supplements value shopping for will include particular strains at exact quantities that display clinically-proven advantages at these ranges.

Equally, one other key issue that far outweighs the precise measure of CFU counts (at face worth) is that the probiotics will survive lengthy sufficient to make it into your system and really yield a given profit. “For instance, Activia yogurt features a signature probiotic tradition Bifidus (Bifidobacterium lactis DN-173 010/CNCM I-2494), plus 4 further dwell cultures. The Bifidus tradition was particularly chosen due to its capability to outlive passage by the digestive system and attain the massive gut in ample quantities,” Dr. Freitas says. One other must-know tip: “It is best to keep away from merchandise stating CFUs at ‘time of manufacture’ as a result of these don’t account for declines in probiotic numbers throughout storage,” he provides.

In different phrases, shoppers have to dig deeper and transcend merely searching for the best CFU counts—in addition to learn the wonderful print to make it possible for the variety of CFUs listed will stay intact from product improvement to supply and all the way in which to your digestive system.

Are extra probiotic species and strains higher?

Typically, you’ll see {that a} probiotic meals or complement comprises a mix of species and strains—typically throughout a variety of genera (e.g. Lactobacillus, Bifidobacterium, Bifidobacterium)—which can additionally lead you to default again to that “extra the merrier” mentality. In any case, range is the secret in the case of intestine well being, proper? Nicely… not so quick. Piggybacking off the mythbuster above, a probiotic that comprises a wide range of strains (inside or throughout genera or species) additionally doesn’t inevitably imply that it’s superior.

“Once more, particular strains are linked to completely different advantages,” Dr. Freitas says. “Consultants have prompt that the majority probiotics have strain-specific mechanisms of motion, however typically the identical species and genus can have related advantages.” For instance, some—however not all—Lactobacillus will provide related advantages, but “with out learning the particular pressure there isn’t any strategy to know which micro organism present advantages and which don’t,” he continues.

Learn: Exact and conclusive analysis, somewhat than a better quantity of CFUs or strains, is most essential. One probiotic pressure at a decrease CFU rely may be simply as efficient as a dozen strains throughout genera to yield a given profit—as long as all of the numbers match as much as stated profit that has been confirmed to be efficient in a medical setting.

Determine what profit you’re searching for most and take issues from there.

2. Search out transparency

“I at all times say that not all probiotics are created equal,” Dr. Freitas continues. “There are lots of probiotic merchandise which might be doubtful of their high quality and making numerous claims, each in meals and dietary supplements which might be unsubstantiated by neither science nor medical research.”

With that in thoughts, some manufacturers can be extra clear than others. You’ll wish to search for people who not solely clearly listing the strains, but additionally present the proof to again up the profit(s) their product purportedly affords. “First, I might advise shoppers to verify the product label to see if the total pressure identify of the probiotic is listed,” Dr. Freitas says. “Then verify on the corporate’s web site to seek out out if research had been performed and to be taught extra concerning the particular strains within the product.”
