are lactase drops for infants safe

It can be incredibly alarming to learn that your infant has trouble digesting lactose, a sugar in dairy products. Fortunately, parents have an option to help aid in digestion and make consuming dairy easier for their baby: lactase drops. But are lactase drops for infants safe?

Generally, Lactase drops are a safe, effective way to help infants digest sugars found in dairy products, such as lactose. Lactase drops are usually produced from bacteria and the Lactobacillus enzyme it produces.

This enzyme helps break down lactose into more digestible forms. However, lactase drops should only get used in cases of lactose intolerance—not as a preventative measure.

Though lactase drops are a safe method of helping babies digest lactose, monitoring their consumption is still important. Too much consumption of lactase drops may create an imbalance of bacteria, affecting their digestion. It’s important to talk to your doctor, who can provide a safe dosage of lactase drops.

Also, lactase drops may cause bloating, flatulence, and abdominal pain. Find out if your baby has these symptoms or any other digestive issues while consuming lactase drops.

Let me take you through lactase drops and safety for your infant.

What Are Lactase Drops?

Lactase drops are a dietary supplement to complement diets with dairy-based foods that are difficult to digest. Lactose is the central sugar in milk and other dairy products. Individuals who are lactose intolerant don’t produce sufficient quantities of the enzyme lactase to digest it properly.

Lactase drops contain the enzyme lactase to provide relief to those who suffer from lactose intolerance, which answers your question, is lactase enzyme safe?

The drops break down lactose in the small intestine for easy digestion and prevent uncomfortable symptoms of lactose intolerance.

Most lactase drops come in liquid or chewable form, and you can take them before eating dairy products or add them to dairy products for easier digestion.

Unlike other treatments for lactose intolerance, such as lactose-free milk and lactose-removed dairy products, lactase drops are not permanent solutions. You may take them regularly to relieve symptoms.

Other dietary supplements alongside lactase drops are still key for your gut health and overall body functioning.

What Causes Lactose Intolerance in Babies?

In babies, lactose intolerance is caused by an underdeveloped or immature digestive system. When babies are born, their digestive system is still developing. The enzyme that breaks down lactose, called lactase, is not as active at this stage until the digestive system is fully developed.

The lack of active lactase may hinder lactose digestion, leading to lactose intolerance symptoms.

Mostly, babies may have a genetic predisposition to lactose intolerance. In these cases, the body may not produce enough lactase enzyme to break down lactose, causing symptoms.

Another possible cause of lactose intolerance in babies is secondary lactose intolerance. Secondary lactose intolerance occurs when the baby’s digestive system has gotten damaged due to a gastrointestinal illness or taking certain medications.

Lastly, some babies can acquire temporary lactose intolerance after experiencing prolonged formula feeding. When feeding on formula instead of breast milk, babies may not get used to large amounts of lactose and may lack enough lactase to digest it adequately.

Signs of Lactose Intolerance in Babies

Lactose intolerance in babies occurs when a baby cannot create enough of the enzyme lactase to digest lactose. The symptoms of lactose intolerance in babies typically include frequent or recurring bouts of vomiting, abdominal pain or cramping, and diarrhea.

The infant may also show poor weight gain or failure to thrive, as improper digestion can lead to malnourishment. Another sign is frequent crying or constant fuss after drinking milk or taking any dairy product.

A baby may also experience excessive gas, bloating, colic, and bad breath. Constipation is a common symptom of lactose intolerance, along with vomit with a greenish hue. Some babies may also experience a rash, particularly around their mouths.

Babies who suffer from lactose intolerance immediately begin displaying symptoms after drinking any quantity of milk or consuming dairy products. If your baby exhibits any of these symptoms after drinking milk, your infant may be lactose intolerant and should seek medical care.

How to Help As a Parent

As a parent, it’s essential to recognize the signs of lactose intolerance in your baby. You should check with your doctor if you think your baby may be experiencing discomfort after consuming milk products. Your doctor will be able to properly diagnose lactose intolerance and recommend a suitable alternative for your baby.

The most common solution for lactose-intolerant babies is the use of lactose-free formulas. These are available in both liquid and powder form and do not contain any of the milk proteins that cause the symptoms related to lactose intolerance.

Instead, they contain carbohydrates, proteins, and other nutrients to provide all the nourishment a growing baby needs.

In addition to using a lactose-free formula, you can reduce symptoms in your baby by introducing lactose-free milk products, such as almond milk, soy milk, and lactose-free yogurt. Lactase drops or supplements can also help digest the lactose in regular dairy products. Discuss this with your doctor.

As a parent, it’s also important to remember that lactose intolerance does not mean that your baby will never consume lactose-containing products. With proper monitoring and treatment, babies with lactose intolerance can enjoy dairy products in moderation.

Lactase Drops for Infants FAQS

Is Lactose-free Milk Good for Babies?

Yes, lactose-free milk is an option for babies who cannot tolerate lactose or are intolerant or allergic to cow’s milk or dairy products.

It contains protein, calcium, and vitamins A and D, which are necessary for healthy development. It may help ease digestive symptoms like bloating, abdominal pain, and diarrhea due to lactose intolerance or dairy allergy.

However, lactose-free milk is still not a perfect substitute for breast milk or formula, as babies may not absorb some important nutrients similarly. 

If a baby has digestive issues, check in with a pediatrician to determine what nutrition would be best for the little one. Other options are soy, almond, coconut, or oat milk.

It is important to remember that lactose-free milk is not suitable for babies under 12 months. Comparing the nutrition profile of different milk options help in deciding what kind of milk to offer.

How Do You Use Lactase Enzyme Drops for Babies?

Why is lactase added to baby milk? Lactase enzyme drops can get added to the formula or put directly into the bottle to help break down lactose. Following the dosage instructions printed on the package is best to use these drops.

For example, you typically add five drops of lactase enzyme per ounce of formula or breast milk your baby is drinking. It should get added to the bottle or formula just before feeding.

Ensure the lactase enzyme drops are completely mixed in, and gently shake the bottle before feeding. Always consult your pediatrician before feeding your baby formula or breast milk with lactase enzyme drops. You may still explore the common question, ‘how does milk without lactose taste?

Is Lactase Enzyme Safe for Kids?

Yes, Lactase Enzyme is generally safe for kids as long as it is from a reliable source and taken in appropriate amounts. Lactase is an enzyme found in the small intestine of humans. 

It is responsible for breaking down the lactose molecule of milk into two simpler forms of glucose, glucose, and galactose, which the body can then absorb.

When people lack enough lactase, they suffer from lactose intolerance and cannot digest the lactose found in dairy products. If a child has lactose intolerance, then Lactase Enzyme may enhance their ability to digest the dairy product.

However,  parents consult with their physician or a healthcare provider before taking any enzyme supplement if the child is under 18.

It is also important that Lactase Enzyme get taken before consuming dairy products. So digestion can gets aided, and the discomfort caused by lactose intolerance gets minimized.

Does Lactose Intolerance in Babies Go Away?

Yes, lactose intolerance in babies can go away. Lactose intolerance newborn can occur when babies cannot digest the sugar found in breast milk or cow’s milk. This intolerance is most common in babies under six months old, but they typically outgrow it.

In some cases, the baby may still have difficulty with lactose digestion even after six months. In this case, the parents can look into lactose-free formulas and strategies to help the baby tolerate lactose-containing milk. 

This may include adding lactase enzyme drops to the milk before the baby consumes it. This approach may still answer your question, “Is it OK to give baby lactose-free milk?

Ultimately, for most babies, lactose intolerance goes away over time. Still, parents need to keep an eye on their babies’ development and check in with their pediatrician if they notice any troubling symptoms.
