3 Lactobacillus Paracasei Health Benefits
The gram positive lactic acid probiotic Lactobacillus Paracasei strain is found in various fermented dishes and supplements.
In this guide I am going to look at what the scientific studies have to stay for the Paracasei bacteria.
Lactobacillus Paracasei Benefits
Thankfully Lactobacillus Paracasei is a strain that has been extensively studied. Some of the studies were carried out on mice, rats, piglets and other's on humans. I will make clear when each either subject is used.
There are a few different clinical studies out there for upper airway allergies like rhinitis. One placebo-controlled study was carried out on 31 adults with pollen allergies over 4-weeks. They were given ST11-fermented milk before being triggered with allergens and the technical markers showed improvements in some participants symptoms vs the placebo group
The conclusion of this first study said:
"data strongly suggest that probiotics may down modulate key parameters of allergic rhinitis and warrant future evaluation in seasonal trials." which is quite straight to the point. (1)
This second study was done on people with house dust mite triggered rhinitis and involved the Lactobacillus paracasi 33 (LP33) strain. 90 paitents were involved in this second study and it again it was placebo controlled. Instead of the fermented milk they were given 2 capsules daily for 30-days and the study concluded with the following statement:
"Our results suggest that heat-killed LP33 can effectively improve the overall quality of life for patients with allergic rhinitis, and that it may be efficacious as an alternative treatment." (2)
Many people with IBS end up turning to probiotic supplements for help. Sometimes they work and other times they make things worse.
This study on mice with IBS (yes, mice can get ibs) showed that specific technical markers related to IBS like muscle hypercontractility for example were improved. The study concluded with the following sentence:
"Lactobacillus paracasei may be useful in the treatment of postinfective irritable bowel syndrome." (3)
If constipation is a symptom of your IBS then this study may be of interest. It is also a little less technical than the previous mouse study. In the study, 20 constipated participants were given Lactobacillus Paracasei soaked artichokes (a good prebiotic by the way) in a placebo controlled study. The study concluded with this statement:
"This trial shows a positive effect on symptoms in constipated patients after intake of probiotic-enriched artichokes." (4)
Interestingly acute diarrhea was also studied with the probiotic strain Lactobacillus paracasei B21060 on 55 children and the result was
"The synbiotic formulation studied is effective in children with acute diarrhoea."
Not much more information was given in this study compared to others unfortunately but it does seem to bolster up the claim for its use with IBS related symptoms. (5)
Weight loss is a bit of a controversial area when it comes to probiotics. I have reviewed supplements in the past created for weight loss and the customer reviews weren't always that positive.
The first way probiotics are said to help with weight management is through altering your appetite. This L. paracasei and L. Casei study carried out on piglets over 2 weeks showed that "The probiotic bacteria L. casei W8 appears to lower food intake acutely, but the underlying mechanisms are not understood." (6)
Other L. paracasei studies were carried out mice and rats and they showed decreased body weight in obese rats (7), reduced body weight and abdominal fat weight in rats (8) and decreased body weight in mice. (9)
All of the studies are well done and well worth reading if you are looking to trying a L. Paracasei supplement for weight issues. Just keep in mind most of the studies were not carried out on humans. Lactobacillus Gasseri does however have one great weight loss study that had human participants.
Where To Find L. Paracasei Supplements?
If you are looking for a probiotic supplement with the Lactobacillus Paracasei probiotic strain then don't worry, there are plenty out there. The probiotic supplement FlowFlora for sale on AliciasNaturals.com has a 40-billion CFU and contains the Lactobacillus Paracasei strain.
If you are not a fan of swallowing capsules everyday then you can get L. Paracasei from Yogurts at your local store and fermented foods like Kimchi, Sauerkraut, Kombucha. The amount of probiotic bacteria you are ingesting this way will be more guess work than scientific fact.
Lactobacillus Paracasei Side Effects
I am not a doctor and nothing in this guide is medical advice. According to WebMD, stomach gas and bloating may occur. (10) They go on to say that you should consult a doctor right away if you experience any side effects.
It's a shame to see Lactobacillus Paracasei not being studied so extensively in comparison to strains like L. Reuteri.
I would love to thank the scientists out there for taking the time to conduct all of these in depth high quality clinical studies for our benefit. If I find any more data out there I will be sure to update this L. Paracasei guide.
