Lactobacillus aids pigs' health
We explored the effects of Lactobacillus acidophilus fermentation products on weanling pigs that were challenged with a harmful strain of bacteria known as enterotoxigenic F4 Escherichia coli (F4-ETEC). To better understand this, we conducted a detailed study involving eighty pigs, which were divided into five groups based on different diets. This included a control diet, as well as diets supplemented with various fermentation products and zinc oxide.
After inoculating the pigs with F4-ETEC to simulate infection, we observed significant changes in the pigs’ fecal microbiome when they were given a combination of Lactobacillus and Saccharomyces products. These changes in the microbiome were previously linked to better growth performance and overall health in young pigs.
Interestingly, the pigs receiving both Lactobacillus acidophilus and Saccharomyces cerevisiae products showed an increase in final live weight. This suggests that using these postbiotics could help manage performance issues associated with ETEC without needing to eliminate the bacteria entirely from the pigs' environment. Therefore, while Lactobacillus acidophilus was not the sole hero in this study, its combined use proved beneficial in combatting the negative effects of this bacterial challenge.

Effective against dysbacteriosis
51 people found this helpful
Powerful Probiotic Acidophilus Bacteria Blend. Many perceive the 21st Century brand as low-cost and ineffective, but after trying various supplements, I've found this probiotic particularly beneficial. This summer, I battled food poisoning and subsequent dysbacteriosis, experiencing severe bloating and nausea. I relied on this probiotic, and within 3-4 days, most symptoms improved significantly. I took one capsule daily on an empty stomach, alongside increased dietary fibre. This product exceeded my expectations. Additionally, a friend recovering from surgery and antibiotics found it remarkably effective as well. Many use these probiotics for yogurt making, though I haven't tried it myself. They’re stabilised, require no special storage, and are less allergenic. The capsules are a manageable size, containing 1 billion live cultures, including Lactobacillus and Bifidobacterium.

I absolutely love them! They’ve been effective for my child, ensuring no constipation and helping us both recover from infections. They’ve also improved my microbiome and digestion. I even made fermented milk with them. Overall, they’re an outstanding supplement and have provided us with numerous benefits.

Relieved bladder infection

I have bought this several times. Since I turned 48, I've struggled with a urinary bladder infection, which has necessitated frequent doctor visits. After many antibiotics, I searched for alternatives and found this supplement, which has significantly helped. I haven't experienced a bladder infection for two years and consider it essential for my health.

Strong immunity
This affordable long-term probiotic was vital after my antibiotic treatment for pneumonia, which was complicated by a bacterial infection. Antibiotics destroy intestinal flora, essential for immunity. Thus, I was prescribed probiotics from the start, and the effects were positive. After a month of use, my son and I showed improvements in our well-being and stool quality. I highly recommend this probiotic for strengthening immunity.

Effective post-COVID recovery
This product helped restore my intestines after the COVID infection! The price is fantastic. After spending heavily on pharmaceutical drugs, I found this remedy and am incredibly pleased with the results. It's wonderful to have access to iHerb.

Sinus infection prevention
2 people found this helpful
Surprisingly effective! I have previously used pricier brands with less success. After starting these over a month ago, I found them quite powerful, and they took some time to kick in. Typically, this time of year leads to sinus infections for me, but these probiotics have helped me stay healthy and avoid infections thus far. Don’t underestimate their low price; they are most definitely effective!

Stops bacterial growth

This product significantly aided my metabolism, leading to regular bowel movements. I previously suffered from a flora infection every month before my period for six months, but after using this product, I noticed a halt in bacterial growth. I feel much healthier now.

Quick activation
I purchased 100 tablets along with a prebiotic and take one of each daily. It may be a synergistic effect, but it worked remarkably fast! The bacterial activation from this supplement is vital for maintaining health, which is often challenging to achieve through diet alone. I wish to continue using it!

Quick recovery
I enjoyed making yoghurt with this great probiotic, but its true value shone during my intestinal infection, aiding my rapid recovery from severe gastrointestinal issues. I believe the dosages are ideal for these conditions, requiring just one capsule daily.

Restores gut health
After taking antibiotics for various infections, my intestinal microflora suffered greatly, leading to persistent diarrhoea. Unfortunately, prebiotics and other aids did little to help. However, these probiotic vitamins became my saviour! I recommend taking them ten minutes before meals for optimal results.
