Lacticaseibacillus rhamnosus shows promise
We explored the potential of Lacticaseibacillus rhamnosus GG as a probiotic treatment against avian pathogenic E. coli (APEC) in chickens. Our study showed that this probiotic significantly reduced APEC colonization in the chickens' cecum and improved the balance of gut microbiota over a 24-hour period.
Through laboratory evaluations, we detected novel bioactive peptides in the probiotic's culture supernatants, which may contribute to its antibacterial properties. While the results are promising for poultry health, more research is needed to optimize its use in real farming conditions.

We aimed to find out if probiotic supplements like lactobacillus acidophilus could help counteract the negative effects of iron fortification, which has been linked to increased diarrhea and food poisoning among children.
In our study with weaning mice, we discovered that high iron diets led to more severe symptoms when infected with Salmonella.
However, when we added lactobacillus acidophilus beforehand, the mice showed less severe symptoms and better intestinal health.
This suggests that probiotics can really help protect gut health against the adverse effects of iron supplements during foodborne infections.

We explored the effectiveness of a synbiotic treatment combining Bifidobacterium longum and xylo-oligosaccharides in fighting Campylobacter jejuni, a major cause of food poisoning. The treatment was administered either from day one or day fourteen of the chicks' lives.
Our findings showed that early supplementation led to a significant reduction in C. jejuni levels compared to later treatment. However, Bifidobacterium levels did not significantly differ among treatment groups. These results suggest that early synbiotic use alongside other safety measures could help improve poultry meat safety.

Stomach issue resolution
11 people found this helpful
This is by far the best probiotic I've ever taken. I've never noticed benefits from probiotics before, but this product completely resolved my stomach issues that had persisted for months. My anxiety has also lessened, likely due to this remedy. Digestion has vastly improved, and I’ve not experienced bloating since. Though pricey, I recommend it for anyone with stomach or gut troubles.

Dysbiosis resolution

Thank you, Now Foods, for this exceptionally effective probiotic! One package resolved my dysbiosis after extensive antibiotic treatment. Now, we have transitioned to a four-month prophylactic plan with fewer probiotics.

Quick stomach relief
1 people found this helpful
This probiotic is my go-to choice. After searching for effective options, I found this one to be the best. They act quickly and strongly; when spicy food causes stomach discomfort, taking one soothes me within five minutes. The high 100 billion count is rare, and while it's a bit expensive, it's worth it. I appreciate that it's in powdered form, making it potent and effective.

Probiotics reduce Salmonella colonization
We looked at how an avian-specific probiotic could help reduce food poisoning risks linked to Salmonella Enteritidis in poultry. Our study used chicks that received a special probiotic treatment and compared them to a control group.
The results showed a marked decrease in Salmonella Enteritidis colonization in the treated chicks over several days, especially at days 3, 7, and beyond. However, body weight gains appeared similar between both groups.
Overall, our findings suggest that using Lactobacillus acidophilus as part of the treatment may effectively lower Salmonella risks in broilers.

We aimed to see how a synbiotic mixture might help reduce Campylobacter jejuni, a harmful bacteria often found in poultry, which can cause food poisoning in humans. Through our research, we provided broiler chickens with a blend of prebiotics and a specific strain of Bifidobacterium longum.
After 14 days, we observed a significant reduction in C. jejuni levels in the feces of treated chickens. This suggests that such synbiotic treatments could be an effective strategy for enhancing poultry safety and reducing foodborne illnesses linked to poultry products.

Bloating relief noted
2 people found this helpful
An excellent probiotic that I've reordered several times. It significantly alleviates my gut issues and constant bloating. After just a week of intake, the main symptoms vanish, making food easier to digest. Maintaining a good diet is crucial, as without it, no probiotic will be effective.

Gut lining strengthening
5 people found this helpful
After switching from their 50 billion to this dosage, I initially felt ill and had stomach cramps for about half an hour, but subsequent adjustment revealed benefits. My tolerance for previously difficult foods, especially high-histamine ones, has improved significantly. This has aided my IBS symptoms and strengthened my gut lining, supported by a no-sugar, natural diet.

Digestive health improvement
16 people found this helpful
After being hospitalised for 25 days, I took antibiotics that ruined my intestinal flora. Once I began taking probiotics, my system improved but not adequately. Then I discovered Now Food's probiotics with 100 billion cells. Initially, I was concerned it might be excessive, but it proved essential for recovery. Following an adjustment period, my intestinal health improved significantly in just over a month.

No improvement experienced
Excellent quality, but unfortunately, it did nothing for my intestines. I've tested several brands without success, and my stomach pains and diarrhoea persist. I've struggled with irritable bowel syndrome for several years without relief.

We explored whether Lactobacillus acidophilus, in both live and heat-killed forms, could protect against Salmonella-induced food poisoning. For two weeks, Sprague-Dawley rats received oral doses of L. acidophilus before being exposed to Salmonella.
The rats treated with heat-killed bacteria showed only a moderate rise in body temperature and maintained normal feeding and drinking habits. Although the number of Salmonella in feces was similar in both groups, heat-killed L. acidophilus significantly reduced inflammatory markers compared to the control group.
While it appears L. acidophilus may aid in managing Salmonella infections, it’s important to note that its overall impact may be limited.
