Free Soul 50 Billion CFU Pro Bio Cultures Complex is one of 57 probiotics & gut health products on our shelf, compared on what buyers rated it, how many of them there were, and what it costs today. Here is how the maker describes it: Our advanced formula contains 50 Billion CFU per single capsule, with 16 live bacteria strains. Our capsules are easy to swallow, shelf life stable, and vegan. For best results. Our comprehensive formula contains 16 strains of live bacteria. The live strains include Bifidobacterium Bifidum, Lactobacillus Brevis, Lactobacillus Acidophilus. That is the maker talking, not us, so read it as a claim rather than a finding. On Amazon it sits at 4.4 out of 5 across 279 ratings. How that compares with the rest of the shelf is below.
The label gives a CFU count but no strain code. A strain is only fully identified when the genus, the species and the strain number are all given, the way B. longum 35624 is. Without that number, published research on a particular strain cannot be attached to what is in this pack.
Taken from the wording on the listing itself and the price we track, not from a brand claim about value. How we rank →
Across the 57 rated probiotics & gut health products we track, the middle of the pack sits at 4.5 out of 5. This one scores 4.4. Bottom quarter of the shelf. Not a red flag by itself, but similar money buys a better-rated option here, so the case for this one has to come from somewhere else.
279 people rated it, where the shelf median is 258. That's enough for the score to mean something without being the last word on it.
On money, this sits in the middle third of a shelf running from £5.79 to £150, with the midpoint around £14.99. That's where most sensible buys land, neither the cheapest thing on the shelf nor the one you pay a name for.
