Top Medical Research Studies

Our research aimed to understand how a specific symbiotic gel, containing Lactobacillus acidophilus, affects gastrointestinal symptoms, including heartburn, in hemodialysis patients.

We conducted a double-blinded, placebo-controlled trial with 42 participants over two months. The group receiving the symbiotic gel reported significant improvements in the frequency and severity of symptoms like heartburn and stomachache compared to the control group.

Overall, the gel appeared safe with no adverse effects noted. More extensive studies are needed, but these findings suggest promising benefits for managing heartburn in dialysis patients.

Probiotics improve GI symptoms post-surgery
We examined whether probiotics could ease gastrointestinal (GI) discomforts after gastric bypass surgery. In a double-blind, randomized study, 60 patients were assigned to receive either Bifidobacterium longum, another probiotic, or digestive enzymes. After just two weeks, everyone saw notable improvements in their quality of life. Specifically, symptoms like heartburn, gas, and abdominal bloating lessened significantly. While this is promising, the long-term benefits of probiotics in managing GI episodes post-surgery remain to be fully understood.

Food supplement enhances heartburn relief
We evaluated a food supplement that contained the probiotic Lactobacillus acidophilus, along with peptides and multivitamins, to see if it could help relieve heartburn in people with mild-to-moderate gastroesophageal reflux disease (GERD).

In a well-structured, randomized, double-blind, placebo-controlled study, 56 adults took either the supplement or a placebo for 28 days.

Results showed that those taking the supplement experienced a significant decrease in heartburn frequency and severity, along with a drop in over-the-counter medication use. Overall, participants reported improvements in their quality of life compared to those on placebo.

Acid reflux healed

Simply the best! After trying numerous probiotics without any noticeable results, Garden of Life’s Primal Defense Ultra proved effective. I took three capsules daily for three weeks, and I’m pleased to say my acid reflux is completely healed! I recommend this product wholeheartedly, and even after reducing my dosage, I haven't had any heartburn.

No more heartburn, no more constipation. Amazing. Truly. If one a day does not suffice, try two, then three. This is exactly what our bodies need.

Ultimate effectiveness
My doctor recommended this product, and I take it daily throughout the year. I found it excellent. My parents use it as well. I used to suffer occasional stomach upset or heartburn, but since starting Primal Defense, all that has vanished. While overseas, my friend forgot her IBS medication and felt unwell. I offered her Primal Defense, and she took two capsules each day, experiencing no further problems from the first day.

Heartburn subsided
13 people found this helpful
Glad I stuck it out! Initially, I experienced horrendous heartburn and stopped using this probiotic. However, after reading about the gut's healing process, I tried again and persevered. After about five days, the heartburn subsided, and I no longer experience discomfort. I take it with food, which I find helpful, and my belly bloat has diminished.
