Most probiotics exert their beneficial effects in the gastrointestinal tract, where they establish dominance within the intestinal microbiota. When disease-causing bacteria invade the body, beneficial bacteria work to combat the harmful bacteria and restore bodily equilibrium. It’s important to note that not all beneficial bacteria are identical — each strain offers different effects, and PB8’s eight strains work together to deliver comprehensive benefits.
Lactobacillus is one key genus found in PB8 Probiotic, playing a crucial role in gut health. Let’s examine the eight different probiotic strains in this supplement (hence the name).
Lactobacillus acidophilus
Acidophilus is one of the most renowned probiotic bacteria due to its significant bodily effects. It can help prevent various digestive issues including irritable bowel syndrome (IBS), diarrhea, constipation, dyspepsia, and bloating. Additionally, this bacteria can aid in fighting certain allergies, preventing vaginal infections, promoting weight loss, strengthening immunity, and reducing cholesterol.
Lactobacillus rhamnosus
Rhamnosus ranks among the most common probiotic types. It was actually the first probiotic strain identified for commercial use due to its excellent growth qualities, ability to attach to the intestinal wall, and resistance to bile and acids. Various studies show this strain effectively strengthens immunity, treats gastrointestinal infections, increases insulin sensitivity, manages weight, and counteracts depression and anxiety.
Lactobacillus casei
Casei exists naturally in the intestinal tract and reproductive system, and is also found in raw cow’s milk and breast milk. This bacterial strain produces lactic acid through fermentation and is commonly used to create probiotic-fermented foods and beverages such as yogurts, cheeses, pickles, and wines. L. casei is recognized for remarkable effects on immunity, digestion, allergies, and infections.
Lactobacillus plantarum
Plantarum is among the most resilient probiotic strains, thriving in temperatures between 1 to 60 degrees Celsius. It can survive in low pH environments and withstand high bile acid conditions. L. plantarum is powerful in combating pollutants to reduce oxidative stress, boosting iron absorption to prevent iron deficiency anemia, regulating blood pressure to support heart health, maintaining a healthy GI tract to prevent digestive issues, and defending immunity to improve overall wellness.
Lactobacillus salivarius
As the name suggests, L. salivarius is bacteria prevalent in saliva, though it’s also present in the small intestines, colon, and vagina. It’s recognized for rapid growth and spread capabilities. This advantage enables it to quickly crowd out harmful bacteria. This strain is also essential for maintaining oral hygiene, alleviating gut disorders, inhibiting vaginal infections, preventing asthma and strep throat, and blocking pathogenic bacteria such as E. coli and Salmonella spp.
The Bifidobacteria genus plays an essential role in the body’s homeostasis. It’s one of the most well-studied and established bacteria that provides positive health benefits to hosts through metabolic functions.
Bifidobacterium bifidum
Bifidum is the most common probiotic bacteria in the human body. It can also be synthesized and is widely used in fortifying dairy products and frequently appears in probiotic supplements. This strain protects against infections, prevents stomach problems, optimizes immunity, and improves nutrient absorption.
Bifidobacterium longum
Longum has been registered as Generally Recognized as Safe (GRAS) and is among the first bacteria originating from a newborn’s colon. Research shows this beneficial bacteria can help reduce inflammation, combat infections, reduce obesity, restore immune function, and relieve anxiety.
Bifidobacterium lactis
Lactis is a multi-functional probiotic bacteria residing in the GI tract. It’s a substantial strain verified to boost digestion, reinforce immune system functions, and resist tumor growth. It also plays a vital role in breaking down body waste, normalizing blood sugar levels, preventing eczema, fighting certain allergies, and assisting vitamin and mineral absorption in the gut.
Advantages And Disadvantages Of PB8 Probiotic
As evident from the benefits section above, PB8 Probiotic offers numerous advantages. Beyond the excellent ingredients, the probiotic comes in a BPA-free bottle, which isn’t as common as you might expect. It’s also highly allergy-friendly, with capsules free of soy, gluten, milk, wheat, eggs, peanuts, or tree nuts. The capsules also include inulin, a prebiotic that aids digestion and overall gut health while feeding the probiotics to keep them viable.
Regarding disadvantages, there are only a few concerns. The primary downside is that probiotics are only guaranteed at manufacture time, not until a specific expiration date. This raises questions about whether the probiotics remain viable by the time consumers purchase or consume them.
Additionally, the probiotic states it’s not safe for children. This is unusual since probiotics are typically fine for kids. This could partially be due to one included strand: Lactobacillus casei. This specific strain has been known to overpower beneficial bacteria and act aggressively in the body, potentially defeating the supplement’s purpose by hurting other bacteria’s survival chances.
The inclusion of this strain likely stems from its ability to help with gut-health issues like diarrhea and constipation.
Is PB8 Probiotic Safe?
Generally, PB8 Probiotic is considered safe. However, expect potential stomach cramps lasting a few days since the dose is relatively high for a probiotic supplement.
If you experience side effects, it’s likely due to multiple probiotic strains hitting your gut biome simultaneously, so consider reducing your intake.
Should You Buy PB8 Probiotic?
If you’re seeking a probiotic that includes prebiotic inulin and features diverse probiotic strains, PB8 Probiotic might suit your needs. It’s also exceptionally allergy-friendly, making it helpful for those with allergies. It’s free of soy, gluten, milk, wheat, eggs, peanuts, and tree nuts.
As always, consult your doctor before purchasing any probiotic, especially if you have a history of gut health issues.
