Our body is home to many microorganisms, and not all are harmful to us. A few microorganisms, called probiotics, live in symbiosis with us and can be found lining our digestive tract, urogenital tracts, and mouth (1). This post talks about the benefits of probiotics for children you should know.
Probiotics can be obtained from fermented foods or supplemented by the body. These live and beneficial bacteria or yeast are helpful when given in the right amounts. They help ward off the harmful microbes that enter one’s body during an infection. They also help digest food and absorb nutrients (2).
Are Probiotics Good For Children?
Probiotics are generally safe for children and beneficial for the gut. They may help in the prevention of upper respiratory tract infections and diarrhea. Probiotics release metabolic by-products that act as immune health modulators and help maintain a healthy gut environment (3).
However, probiotics may not be safe for premature infants or children with reduced immune system function or cancer as they may increase the risk of infections (4).
What Are The Benefits Of Probiotics For Children?
- The by-products released by probiotics boost the immune system.
- Probiotics are good for the digestive system, as they aid digestion and proper absorption of certain nutrients.
- The right strain of probiotics can shorten infectious diarrhea and reduce antibiotic-associated diarrhea.
- A few studies have indicated that probiotics can reduce constipation among children (5).
- Certain studies state that probiotics reduce the incidence of irritable bowel syndromeiXA chronic intestinal and stomach disorder characterized by cramping and constipation , Crohn’s diseaseiXA chronic inflammatory condition that affects the digestive system, causing abdominal pain, diarrhea, and weight loss , and pouchitis (a complication following the surgical removal of ulcerative colitisiXAn autoimmune disorder that causes sores, bleeding, and diarrhea in the colon and rectum ) (3) (6).
- When used with antibiotics, probiotics may help prevent urinary tract infections (7).
- A few studies suggest that probiotics could help prevent allergic reactions such as allergic rhinitisiXInflammation of the nasal passage caused by an allergen leading to itching, sneezing, and watery eyes (8).
What Are The Types Of Probiotics For Children?
Three genera of microbes are mainly consumed as probiotics:
- Lactobacillus: The probiotic bacteria Lactobacillus produces lactic acid from milk, protecting the gut from bad bacteria. Lactobacilli are commonly used as probiotic supplements following antibiotic treatment to restore the gut microbiome balance after diarrheal episodes. These friendly bacteria line the gut and vagina (9).
- Bifidobacteria: This species of healthy bacteria also lines the intestine and assists in breaking down the food in the gut and absorbing nutrients (10).
- Saccharomyces boulardii: This yeast is available in supplement form and is used with medications to treat inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis (11).
There are many strains of Lactobacillus and Bifidobacterium. Each subtype of species is mentioned after the abbreviated version of Lactobacillus (L.) and Bifidobacteria (B.).
Since each strain benefits the body differently, probiotic supplements are prescribed based on their effect on the body. L. acidophilus, L. reuteri, B. lactis, B. breve, B. animalis, and B. longum are the commonly available strains of probiotic bacteria.
What Is The Right Dosage For Probiotics?
Each individual has a unique requirement of beneficial bacteria or yeasts. Approximately five to ten billion CFUs (colony-forming units) per day is considered an adequate probiotics dosage. Most probiotic supplements provide around one to ten billion CFU per dose (12) (13).
What Are The Side Effects Of Probiotics For Children?
• Their consumption may be unhealthy for immunocompromised individuals as they may trigger the immune system and worsen the health condition.
• Probiotics may transfer their antibiotic-resistant gene to the harmful bacteria in the gut.
• A Few probiotic products may not specify the strain used in the supplement. Therefore, the consumption of mixed probiotic products may result in other diseases.
• Probiotics may also cause minor digestive issues such as stomach issues, diarrhea (especially in lactose intolerant children), bloating, or flatulence.
• The release of D-lactic acid may cause acidosis in patients with short bowel syndrome (15).
What Are Some Natural Sources Of Probiotics?
Introducing probiotics through natural sources is safer since supplements may not be regulated. However, natural sources of probiotics may contain allergens; hence, always check the ingredient lists of products. Here are a few food sources of probiotics (16):
- Yogurt: This ubiquitous milk product is known for its beneficial microbial colonies. Yogurt contains the strains of Lactobacillus acidophilus or Lactobacillus bulgaricus, which convert the lactose in milk to lactic acid.
Due to its bland flavor, yogurt is versatile and can be combined with fruits as a healthy snack. However, plain yogurt is recommended over the artificial flavors available in the market.
- Kefir: This milk product is harbored by Lactobacillus kefiri. It can be prepared with animal and plant-based milk. The milk is fermented, thickened, and strained to obtain kefir grains, which can be added to plain milk to increase their probiotic quality.
- Buttermilk: Indian buttermilk, and its varieties, such as lassi and chaas, made from unflavored, diluted yogurt, are good probiotics. Alternatively, the cultured buttermilk available in the US does not offer many probiotic benefits.
- Viili: This Finnish milk product with a ropey consistency is cultured by Lactobacillus.
- Pickles and other fermented dishes: Traditionally prepared brine-cured and salt-cured pickles without preservatives such as sodium benzoate are good sources of probiotics. Kimchi from Asia, curtido from Central America, choucroute from France, and sauerkraut from Germany are good probiotic sources.
- Lebne: It is a Middle Eastern cheese made from yogurt and has a thick consistency due to the elimination of whey. It is also known as Greek yogurt or strained yogurt and has an acidic flavor.
What Are The Precautions To Take While Consuming Probiotics?
Probiotics are safer for consumption through food than supplements. According to a study published in the Gastroenterology journal, it was found that one in 20 US adults or children use nonfood pre-, pro-, or synbiotic products, and use has sharply increased in recent years. Here are some precautions you should consider while giving probiotics to a child (2):
- There is no standard regulation for probiotic supplements in the US. You may find them as dietary supplements, food products, or drugs. Since dietary supplements sold as food products may not be FDA approved, they could contain unregulated strains of bacteria, which may have adverse effects.
- Always read the product description and give it at the dose recommended by a medical professional. Although probiotic overdoses do not have known side effects, their consumption may cause minor gastrointestinal disturbances.
- One dosage doesn’t suit all as the microbiome population varies in each individual.
- Stop offering the probiotic if you notice any side effects.
- Some probiotics may need to be stored in a sterile environment or refrigerated to prevent the death of the organisms.
- Read the label for any allergens.
- Probiotics cannot cure diseases and, hence, are not given to replace medications. Watch out for probiotic supplements that offer misstatements about products.
Frequently Asked Questions
1. Do probiotics help children with ADHD?
Yes. Several studies have found a link between probiotics and the improvement of ADHD symptoms. A study found that taking the probiotic Lactobacillus orally for the first six months of life reduced the incidence of ADHD or ASD at 13 years of age (17). Similarly, another study found that children with ADHD who received Lactobacillus rhamnosus GG (LGG) supplementation had a higher health-related quality of life (18).
2. Can probiotics help children focus?
Probiotics play a role in the gut-brain axis and have been shown to improve the cognitive functioning of the brain in human clinical studies and animal studies. However, the exact role of probiotics in this association is yet to be determined (18) (19).
3. At what age can I give my child foods with probiotics?
Probiotics are safe and well-tolerated in healthy babies and children, premature babies, babies with low birth weight, and children with HIV (20). Hence, you may add food sources with probiotics to your baby’s diet after they start eating solid meals (six months onwards).
Probiotics for children are believed to be safe and help by boosting immunity, relieving constipation, etc. However, you should not give them to children without consulting a doctor as it may cause acidosis, bloating, or other side effects. It is important to know that probiotics from food sources are much safer than supplements. However, be cautious of food allergens that may adversely affect your child’s health. Before using any probiotic supplements, read the product details carefully and determine the correct dosage. In case of any concerns, discontinue the usage and talk to your doctor.
