Alflorex is a probiotic supplement manufactured by PrecisionBiotics that contains one patented and trademarked probiotic strain scientifically known as Bifidobacterium infantis (B. infantis) 35624. It is the only product in the UK and Ireland that contains this strain at this time. The names of the product and 35624 are registered trademarks of Alimentary Health Ltd., a company based in Ireland.
This strain is backed by research, but the research may not support the conditions for which many practitioners unknowingly recommend it. Read what the research really shows.
Marketing materials say it "is the #1 Gastroenterologist recommended probiotic culture in the U.S.” This claim is based on a survey performed in 2017 among doctors and/or gastroenterologists who recommended a brand of probiotic by a human data service company, AlphaImpactRx. Marketing materials also state that it is the winner of awards from Irish pharmacists and industry experts, who voted it the winner of Best Gastrointestinal Product for 3 years in a row at the Irish Pharmacy News OTC (over-the-counter) Awards.
There are 3 different formulations of this probiotic supplement as of January, 2019: capsules, straws, and chewables.
Please always read ingredients before taking any supplement! The ingredients may vary depending on the date they are manufactured and depending on the country they are manufactured in or for. This review is for products in Ireland.
The children’s straws (for ages 3 and older) contain rapeseed oil and the probiotic. They, too, contain 1 billion CFU of Bifidobacterium infantis 35624 at time of manufacture. The straws are individually wrapped in foil and extend once pulled upon. The 35624 culture is suspended in the oil droplet in the straw at the blue end of the straw. The blue end should be placed in a cool liquid.
Acidic beverages such as fruit juices should not be used with these straws, but water and milks (cow and alternative milks) are acceptable.
Note that as of January, 2019, the straws are being phased out and will be replaced by new Alflorex Chewables.
The chewables are said on the website to contain isomalt (a sugar-alcohol sweetener), microcrystalline cellulose, magnesium stearate, unidentified flavorings, and sodium saccharin.
They are dairy-free, lactose-free, soy-free, sugar-free and vegetarian. They, also, contain 1 billion CFU of Bifidobacterium infantis 35624 at time of manufacture.
The manufacturer's recommended dosage is 1 Unit (capsule, straw, or tablet) per day for each product.
The reviews on the PrecisionBiotics website show all 5-star reviews.
The 5 verified-purchase reviews on Amazon.com as of April, 2018, show 3.8 out of 5 stars. On Amazon.ca the reviews are from Amazon.com. Some of the more helpful reviews are:
“These probiotics claim to cause no side effects, but two days into taking them, I was sick as a dog. I immediately recovered when I stopped taking them. Everyone is different and you have to remember, you're adding a BACTERIA into your body. This product might work for some, but not for others.” – May 11, 2017
“So far so good. No side effects. Must be working fine since I don't have any discomfort. I haven't noticed anything spectacular, but I've only had it for a little while. I'll have to give it a few more weeks...” – February 2, 2018
On Amazon UK, Alflorex has 4.1 out of 5 stars from 144 reviews as of April, 2018.
Some of the helpful, verified-purchase positive reviews are:
“Took 6 weeks to work properly, I have now successfully stopped the Days of The runs followed by constipation for days thanks to thse pills. Wouldnt be without them now pity nothing on offer from GP's. Highly recommended for IBS.” – July 29, 2017
“My specialist recommended these to me. The first two weeks on these were absolute hell. Unbearable stomach cramps. Needing to run to the toilet at all hours of the day. But by week three a massive change had occurred. I now feel almost cured from the burden that is IBS. I guess the first two weeks were caused by my stomach getting used to the bacteria. Now I am able to stop taking daily dosages of Imodium and not worry.” – October 3, 2017
“My wife has suffered from IBS for years and often cannot leave the house, after a week of this the results are amazing. I am sure it may not work for everyone but after about 30 years of problems it has worked for my wife.
Highly recommended.” – March 16, 2018
Some of the helpful, verified-purchase negative reviews are:
“Expected it would be easy and put an end to the bloating, which was my only complaint. But after two weeks I give up. The panicky urgent race to get to a toilet when out and about, the abdominal cramps, the increased bloating, and worst of all the nightly belly concert of growling, the babbling brook, the off-key violin notes that keep me awake for hours, the rapidly moving gas that forces me to tumble out of bed and run to the toilet, just in case, are intolerable. I'll try something else. Maybe.” – November 24, 2017
“I have so far purchased 2 bottles of Alflorex, for stomach bloating and gas. I am now on the second bottle and have found hardly any difference at all. I understand it takes one month to prime the gut. I would like to know how long it takes to make a difference.” –January 1, 2018
“Bought these after suffering with stomach bloating. Took them for just over 4 weeks hoping they would help but they gave me diarrhoea and stomach pain every day. I was patient and hoped it would settle down but it got so uncomfortable I had to stop. Shame it didn’t work for me” – February 15, 2018

Some competitors of SBI (Solo Build It) are posting fake negative reviews of SBI. If you are considering creating your own website business, or if you have a brick-and-mortar business but want an online presence, I highly recommend SBI!
