Probiotic 40 Billion CFU Review: More CFUs Isn’t Better
I used three probiotics side by side: 40, 60, and 500 billion CFU. Here's why the CFU number matters less than you think.
The Probiotic 40 Billion CFU from BioSchwartz is worth buying if you want a shelf-stable daily probiotic without chasing the biggest number on the label. It’s 40 billion CFU per serving, 60 capsules, no refrigeration. I’ve used it alongside two higher-CFU brands and still reach for it. Buy it.

How this review was made: written from my own video review of this product. Every opinion here is my own, from using it myself.
Quick Verdict
One of these bottles has 12 times the CFU count of the BioSchwartz, and I still don’t think that makes it 12 times better. A CFU is just a count of live organisms. All three of these are great choices, and I’ve used all three.
Buy if you:
- Want digestive, gut, and immune support in one daily capsule
- Don’t want a bottle taking up fridge space
- Care more about strain variety than the headline CFU number
- Want a shelf-stable bottle you can throw in a travel bag
Skip if you:
- Want a one-capsule-a-day bottle, the 40 billion CFU serving is two capsules, so 60 count is 30 days
- Specifically want a men’s-targeted formula
- Are shopping purely on the biggest CFU number
| CFU per serving | 40 billion |
|---|---|
| Capsules | 60 vegetarian capsules |
| Supply | Advertised 30-day |
| Storage | No refrigeration required |
| Includes | Organic prebiotics, astragalus |
| Testing | Third-party tested, cGMP facility |
I Had No Idea What a CFU Was
I’d been taking probiotics for months before realizing the number on the front was just a count of live organisms, not a measure of effectiveness. If you’re like me, same boat. Very simply, very easy: CFU stands for Colony Forming Unit, and all it is is a count of the live organisms in your probiotic. That’s all it is. It does not mean that more CFUs is better or more effective, and that’s the part the labels want you to forget. The Probiotic 40 Billion CFU from BioSchwartz on Amazon is the lowest number of the three bottles I’ve used, and it’s still one I keep buying.
40 vs 60 vs 500 Billion CFU
The spread between these three is enormous and mostly a marketing decision. Besenify runs 500 billion CFU, which is about eight times what Physician’s Choice gives you at 60 billion, and roughly twelve times the BioSchwartz at 40 billion.
Each one has its own advantage, and they’re not the same advantage. Physician’s Choice packs 10 different strains of microorganisms, so you get greater variety in the gut to kind of work on the intestines. That’s a real differentiator to me, more than raw count.
BioSchwartz has the lowest CFU of the three, but its unique factor is being advertised as resistant to stomach acid and biofluids. That gives it an advantage surviving the passage through your digestive tract to get the organisms down to the intestine. A billion CFU that dies in your stomach isn’t doing anything for you. That’s why I don’t rank these by the number on the bottle.
Besenify is also specifically marketed toward men, which narrows it. If that’s not you, the 500 billion number alone isn’t the reason to pick it.
What I Noticed Across Three Brands
All three work for digestive and gut support; the difference is in how they survive your stomach and what they cost per day. The BioSchwartz runs the lowest CFU count and the lowest price of the three, and the acid-resistance claim is the reason I keep it over the 500-billion-CFU bottle, a probiotic that dies in stomach acid before hitting your intestine is just expensive marketing. That’s the actual ranking logic here, not the number on the front label.
Where the BioSchwartz earned its spot in my rotation is the practical stuff. No refrigeration, which matters because I travel and I’m not babysitting a bottle in a hotel mini fridge. It’s non-GMO and gluten free per the label, and for me the gluten free part isn’t a nice-to-have. The formula also carries organic prebiotics alongside the probiotic, plus astragalus, which is more than the plain-count bottles give you.
The Two-Capsule Serving Catches People
The serving size is two capsules, not one, so the 60-count bottle is only 30 days, not 60. So the 60 count bottle is a 30-day supply, not 60 days. I’d rather take one capsule, and I’ll say that plainly. It’s not a deal breaker, but if you’re comparing count-to-count across bottles on an Amazon page, you’ll undercount this one’s cost per day unless you read the serving size.
The shelf-stable formula means you can park it on the counter where you’ll actually see it, that’s the only reason I’m consistent with any supplement. If you’re new to probiotics, the two-capsule serving is easy to split morning and evening while you gauge how your gut responds.
Check the Price Before You Click Buy
The price fluctuates enough that the difference between a good day and a bad day to buy matters, over 3,000 units moved last month alone, which tends to tighten discounts fast. Check the live number before you click; this is one where the Subscribe & Save option, if it’s available, is usually the best per-serving price you’ll find. Over 3,000 people bought it in the past month and it sits around #5,739 in Health & Household, though it’s selling a bit slower than its 90-day average.
So if you need a probiotic for gut health and you don’t want to pay for a number you don’t understand, this is the one I’d start with. Check today’s price on Amazon and compare the serving size against whatever else is in your cart.
Pros
- Advertised to survive stomach acid and bile, which matters more to me than raw CFU count
- No refrigeration, so it travels and lives on the counter
- Organic prebiotics plus astragalus in the same capsule
- Non-GMO and gluten free per the label, third-party tested
- Digestive, gut, and immune support in one daily routine
Cons
- Two capsules per serving, so 60 count is only 30 days
- Lowest CFU count of the three bottles I used, about 12 times less than the Besenify
- Doesn’t advertise a 10-strain blend the way Physician’s Choice does
| BioSchwartz 40B | Physician’s Choice | Besenify | |
|---|---|---|---|
| CFU | 40 billion | 60 billion | 500 billion |
| Edge | Acid resistant | 10 strains | Highest count |
| Count | 60 capsules | 30 capsules | 60 capsules |

Frequently Asked Questions
Does it need to be taken with food?
The label doesn’t require it, and the formula is advertised as resistant to stomach acid and biofluids, which is the whole point of that claim. Follow the bottle’s directions. If your stomach is sensitive to supplements generally, taking it with a meal is a reasonable habit anyway.
Can women take this one?
Yes, BioSchwartz lists it as optimal for both men and women. That’s a difference from the Besenify bottle, which is specifically marketed toward men. If you’re buying one bottle for a household, this is the more flexible pick.
Is it vegetarian and allergy friendly?
The capsules are vegetarian and the label carries non-GMO and gluten free claims. Made in the USA in a cGMP-compliant facility and third-party tested for purity and potency. If you have a specific allergy, read the current bottle label, since packaging and formulas get revised.
How should I store it and how long does it stay good?
Room temperature is fine, no refrigeration required, which is one of the reasons I keep it around. A cabinet or counter away from heat and direct sun is all it needs. Check the date printed on the bottle, and at a 30-day supply per bottle you’re not sitting on it long anyway.
