Probiotics are live microorganisms that provide health benefits when consumed. Foods and supplements enriched with probiotic cultures offer substantial benefits to human health and well-being. Let's explore some of the key probiotic ingredients used in foods and supplements.
Lactobacillus is one of the most common and well-researched probiotic genera. Some of the prominent Lactobacillus species used as probiotic ingredients include:
Lactobacillus acidophilus: One of the most widely used probiotic bacteria, L. acidophilus helps maintain a healthy gut flora and digestive system. It produces several antimicrobial compounds and supports the immune system.
Lactobacillus rhamnosus: This Probiotic assists in digesting lactose, produces vitamin K2 and B vitamins. Studies show it may help manage diarrhea, irritable bowel syndrome, and eczema.
Lactobacillus bulgaricus: Commonly used in yogurt cultures, this thermophilic bacteria helps digest milk sugars. It may boost immune function and lower risk of diarrhea.
Lactobacillus casei: Shirota strain of L. casei is a popular probiotic that supports digestive and immune health. Research links it to lower risk of respiratory illness.
Bifidobacteria are among the first and most abundant bacteria colonizing the gut of breastfed infants. Key Bifidobacterium strains used as probiotic ingredients include:
Bifidobacterium lactis: Found abundantly in the gut and vagina, this probiotic promotes digestive and urogenital health. Studies link it to lower risk of infections.
Bifidobacterium longum: An important early colonizer in the infant gut, this probiotic aids digestion and bowel regularity. It may boost immune defenses against pathogens.
Bifidobacterium breve: Research links this probiotic to better digestive health in infants. It produces extra-cellular compounds with prebiotic properties to nurture other friendly gut bacteria.
Bifidobacterium bifidum: This probiotic aids digestion, reduces diarrhea and boosts immunity. Early gut colonization by B. bifidum appears crucial for proper immune development in infants.
S. boulardii is a non-pathogenic yeast used widely as a probiotic ingredient. Some of its benefits as per research include:
- Maintains healthy gut flora and prevents infections caused by pathogenic bacteria like C. difficile.
- Easily survives stomach acidity and improves digestibility of food components such as proteins, carbs and fats.
- Reduces symptoms of several gut disorders like IBS, Crohn's disease, ulcerative colitis and anti-biotic associated diarrhea.
- Boosts immunity by stimulating antibody production and antimicrobial activity in the gut.
Other Beneficial Probiotic Ingredients
Some other promising probiotic ingredients used today include:
- Streptococcus thermophilus: Used commonly in yogurt cultures to improve digestibility of milk. Fights pathogens in the gut.
- Bifidobacterium breve: Early colonizer in infants, it aids digestion and bowel regularity. Studies link it to better immune defenses.
- Lactobacillus plantarum: Common in fermented foods, this probiotic supports intestinal barrier function and gut-brain communication.
- Lactobacillus reuteri: Colonizes the gut and vagina. Reduces diarrhea, tooth decay, urogenital infections, and necrotizing enterocolitis in preterm infants.
- Lactobacillus casei shirota: Lowers risk of respiratory infections and benefits digestive health per research.
Probiotic supplementation nurtures the microbiome and supports overall health and wellness. Always look for scientifically validated strains with clinical evidence and go for reputed brands. Probiotics are generally well tolerated but mild side effects like bloating may rarely occur. Consult a nutrition expert for suitable probiotic strains tailored to individual dietary and medical needs.
