Moreover, lactase supplements were better able to alleviate key gastrointestinal symptoms, especially gas. Despite the positive findings, a study in BioMed Research International reported significant variability in the response to lactase supplementation. Of the 96 adults given a lactase supplement, only This suggests that other factors may contribute to the inability to metabolize lactose or, alternately, that other types of lactase may be needed to metabolize lactose in certain people.
Lactase supplements themselves cannot improve bone health directly. But because they can help lactose intolerant people eat more dairy without consequence, they can make it easier to consume adequate amounts of calcium. This, of course, can help build and maintain healthy bones while reducing the risk of bone loss and osteoporosis.
According to a study in the journal Nutrients , when those with lactose intolerance avoid or cut back on dairy, they are at risk for bone loss and fractures. But intolerance itself does not significantly affect adults' ability to absorb calcium the same is true for lactase deficiency. Everyone—including those with lactose intolerance—are recommended to consume three servings of dairy a day. Lactase supplements can help you get there.
Lactase supplements are considered safe and well-tolerated with no known side effects. However, people with diabetes need to use lactase supplements with caution. Once ingested, lactase is broken down into simple sugars that can increase your blood glucose level. While this may not cause any significant problems, it is important to check your blood sugar 20 to 30 minutes after taking a dose just to be sure.
On rare occasion, lactase supplements have been known to trigger allergic reactions. In one reported case, a woman who handled lactase supplements for her children but never took them herself experienced a severe, whole-body allergy known as anaphylaxis.
Call or go to your nearest emergency room if you develop hives, rash, shortness of breath, wheezing, dizziness, lightheadedness, rapid heart rate, or swelling of the face, tongue, or throat after taking a lactase supplement. If left untreated, anaphylaxis can lead to shock, coma, respiratory or heart failure, and death. Lactase supplements should not be used by women who are pregnant or breastfeeding as there is not enough information to ensure their safety.
It is also unknown if lactase supplements can interact with other medications or supplements. In addition to capsules and chewables, lactase supplements are sold in powder and drop forms. These can be stored safely at room temperate in a sealed container. Never use a supplement past its expiration date. The standard dose is 6, to 9, international units IU taken immediately before a meal containing dairy.
Others have found that adding 2, IUs of lactase powder to two cups milliliters of milk can help mitigate symptoms. As a general rule, start at a low dose and gradually increase it until you achieve the desired control. Even though you cannot overdose on lactase, taking smaller amounts can reduce the impact on your blood sugar and help you save money.
Always be sure to take a lactase supplement prior to the first bite of dairy. If eating over a duration longer than 20 to 30 minutes say, at a picnic or banquet , take another 2,mg dose during the meal to extend the protective benefit. However, just because you are taking a lactase supplement doesn't mean you consume dairy with abandon. If you are lactose intolerant, it is important to control your intake, skipping the extra cream, cheese, or milk whenever possible or, at the very least, cutting back on portions.
If you're allergic to something, even a tiny particle can be enough to trigger a reaction, while most people with lactose intolerance can still consume small amounts of lactose without experiencing any problems although this varies from person to person. There's no cure for lactose intolerance, but limiting your intake of food and drink containing lactose usually helps to control the symptoms.
Depending on what dairy products you're able to eat, you may also require additional calcium and vitamin D supplements to keep your bones strong and healthy. In some cases, your GP may refer you to a dietitian for further advice. In addition to dietary changes, lactase substitutes may also be helpful. These are drops or tablets you can take with your meals or drinks to improve your digestion of lactose.
Read more about treating lactose intolerance. Milk and other dairy products contain calcium, protein and vitamins such as A, B12 and D. Lactose also helps your body absorb a number of other minerals, such as magnesium and zinc. These vitamins and minerals are important for the development of strong, healthy bones. If you're lactose intolerant, getting the right amount of important vitamins and minerals can prove difficult.
This may lead to unhealthy weight loss and put you at increased risk of developing the following conditions:. If you're concerned that dietary restrictions are putting you at risk of complications, you may find it helpful to consult a dietitian.
They can advise you on your diet and whether you require food supplements. Alternatively, you can contact a private dietician. The British Dietetic Association has information on how to find a private dietitian.
Lactase is an enzyme a protein that causes a chemical reaction to occur normally produced in your small intestine that's used to digest lactose. After eating or drinking something containing lactose, it passes down your oesophagus gullet into your stomach, where it's digested. The digested food then passes into your small intestine. The lactase in your small intestine should break lactose down into glucose and galactose other types of sugar , which are then absorbed into your bloodstream.
If there isn't enough lactase, the unabsorbed lactose moves through your digestive system to your colon large intestine. Bacteria in the colon ferment break down the lactose, producing fatty acids and gases such as carbon dioxide, hydrogen and methane.
The breakdown of the lactose in the colon, and the resulting acids and gases that are produced, cause the symptoms of lactose intolerance such as flatulence and bloating. Primary lactase deficiency is the most common cause of lactose intolerance worldwide. This type of lactase deficiency is caused by an inherited genetic fault that runs in families. Primary lactase deficiency develops when your lactase production decreases as your diet becomes less reliant on milk and dairy products.
This is usually after the age of two, when breastfeeding or bottle-feeding has stopped, although the symptoms may not be noticeable until adulthood. Secondary lactase deficiency is a shortage of lactase caused by a problem in your small intestine. It can occur at any age, and may be the result of another condition, surgery to your small intestine, or taking certain medication.
Secondary lactase deficiency is the most common cause of lactose intolerance in the UK, particularly in babies and young children. The decrease in the production of lactase in secondary lactase deficiency is sometimes only temporary, but it may be permanent if it's caused by a long-term condition. It's also possible to develop secondary lactase deficiency later in life, even without another condition to trigger it. This is because your body's production of lactase naturally reduces as you get older.
Congenital lactase deficiency is a rare condition that runs in families and is found in newborn babies. It's caused by an inherited genetic fault that means affected babies produce very little or no lactase. The genetic mutation responsible for congenital lactase deficiency is passed on in an autosomal recessive inheritance pattern. This means both parents must have a copy of the faulty gene to pass on the condition. Some babies born prematurely before the 37th week of pregnancy have a temporary lactose intolerance because their small intestine wasn't fully developed by the time they were born.
This is known as developmental lactase deficiency and it usually improves as affected babies get older. It's important to visit your GP if you think you or your child may have lactose intolerance, as the symptoms can be similar to other conditions.
Before seeing your GP, keep a diary of what you eat and drink, and what symptoms you experience. Tell your GP if you notice any patterns, or if there are any foods you seem particularly sensitive to. Your GP may suggest trying to remove lactose from your diet for two weeks to see if it helps to relieve your symptoms. This will provide further evidence of whether you're lactose intolerant. You'll be asked to avoid eating or drinking during the night before the test. When you arrive for the test, you'll be asked to blow up a balloon-like bag.
This sample of your breath will be tested to find out how much hydrogen is present, measured in parts per million ppm.
You'll then be given a drink of lactose solution and your breath will be tested every 15 minutes over the next few hours to see if the level of hydrogen changes. If your breath contains a large amount of hydrogen more than 20ppm above your baseline after consuming the lactose solution, it's likely that you're lactose intolerant.
This is because lactose intolerance can cause the bacteria in the colon large intestine to produce more hydrogen than normal. In a lactose tolerance test, you'll be given a drink of lactose solution and a blood sample will be taken from your arm using a needle. Doctors also can find out if someone can digest lactose by testing for the presence of lactase with an endoscopy. During this procedure, doctors view the inside of the intestines by inserting a long tube with a light and a tiny camera on the end into the mouth.
A doctor can then take tissue samples and pictures of the inside of the gut. The amount of lactase enzyme can be measured in one of these tissue samples. People can manage lactose intolerance by not drinking as much milk and eating fewer dairy products. Most can eat a small amount of dairy. But they need to eat it with other foods that don't contain lactose and not eat too much dairy at once.
You may find that other dairy products, such as yogurt and cheeses, are easier to digest than milk. Lactose-free milk is also a great way to get calcium in the diet without the problems. It can also help to keep a food diary to learn which foods you can or can't tolerate. A lactase enzyme supplement can help too. Taking this before you eat foods that contain dairy helps your body digest the lactose sugar in dairy and prevent pain, cramping, bloating, gas, and diarrhea.
Dairy foods are the best source of calcium , a mineral that's important for bone growth. Because teens need about 1, milligrams mg of calcium each day, experts recommend that even those with lactose intolerance include some dairy in their diet. Talking to a registered dietitian is a good idea. They're trained in nutrition and can you come up with eating alternatives and develop a well-balanced diet that provides lots of calcium for developing strong bones.
Some teens might need calcium and vitamin D supplements. The symptoms of lactose intolerance may look like those of other health problems. Always see your healthcare provider to be sure. Your healthcare provider will talk to you about your past health and family history. He or she will give you a physical exam. You may be asked not to have any milk or milk products for a short time to see if your symptoms get better. While lactose intolerance and irritable bowel syndrome IBS are two different conditions, both can cause similar symptoms for people who drink milk or eat milk products.
This article explains why. There is no treatment that can help your body make more lactase. But you can manage your symptoms by changing your diet. In the past, people who were lactose intolerant were told to avoid dairy products. Today, health experts suggest you try different dairy foods and see which ones cause fewer symptoms.
That way you can still get enough calcium and other important nutrients. He or she can suggest other foods to be sure you get enough calcium. You may need to take calcium supplements. Children with lactose intolerance should be seen by a healthcare provider.
Children and teenagers need dairy foods. Lactose intolerance can affect you every time you eat a snack or meal. So you need to be careful about the foods you eat every day. However, many people can tolerate a certain amount of lactose and don't need to completely avoid it. Lactose is often added to some boxed, canned, frozen, and prepared foods such as:.
Call your healthcare provider if you have trouble managing your symptoms.
