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.
This probiotic supplement is marketed to be clinically tested in people with IBS to reduce:
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 4 different formulations of this probiotic supplement as of April, 2018: capsules, straws, chewables and sachets.
Please always read ingredients before taking any supplement!
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.
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 expected to be in Irish pharmacies by late 2018. 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 sachets for children contain 1 billion CFU of 35624 when manufactured. They come in 14-day supply boxes in two flavors, vanilla and strawberry. The sachets may be mixed with milk or cool water or sprinkled on yogurt, cereal, or other cool foods. At the time of this writing, the sachets are only sold in packs of two with either one individual flavor or one of each flavor.
Other ingredients are not listed on the website, but according to Alflorex, for the vanilla sachets they are maltodextrin, vanilla flavoring, silicon dioxide, and sucralose. The ingredients for the strawberry flavor are the same except for the flavoring, which is strawberry, and the addition of beetroot red color.
The manufacturer's recommended dosage is 1 Unit (capsule, straw, tablet or sachet) per day for each product. The website does caution that you may experience some gas and bloating during the first 4 weeks while your digestive system adjusts to the probiotic. They state that in rare cases it may take Alflorex longer than 4 weeks, possibly up to 8 weeks, to prime your gut, but you should continue to take it for at least 4 weeks.
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
