Does lactase solve the problem of lactose intolerance? How lactase works and where you can find it

Lactose intolerance is a common problem that affects millions of people around the world. The main cause of this ailment is the deficiency of lactase enzyme, which is responsible for digestion of lactose - sugar found in milk and its products. Lactase plays an important role in the digestion process, and its deficiency can lead to unpleasant digestive symptoms. In the article below, we will take a closer look at what lactase is, how it works, and how it can be supported by its action to enjoy the consumption of dairy products without worrying about health.

Lactase - what is this enzyme and how does it work?

Lactase is a digestive enzyme that plays an important role in the digestion process of lactose - sugar present in milk and its preserves. Lactose, which is a disaccharide, consists of two simpler sugars: glucose and galactose. In order for our body to be able to effectively absorb these ingredients, lactose must be spread over these two simpler sugars, which is done thanks to the effect of lactase. This enzyme is produced in the small intestine, mainly by the cells of the intestinal mucosa, known as enterocytes. The mechanism of lactase action is relatively simple - when lactose gets into the small intestine, lactase breaks its glucose and galactose molecule, which is then absorbed into the bloodstream and used as a source of energy. The performance of this process is important to avoid the symptoms of lactose intolerance that may occur when the lactase enzyme is not enough or when its activity is insufficient.

Adult lactase enzyme - role and importance in the digestion of lactose

Although lactase is the most active in infants and young children, its production usually falls as they grow up. In many adults, this leads to a reduction in the ability to digest lactose, which results in symptoms of lactose intolerance. This intolerance is manifested by digestive discomfort, flatulence, diarrhea and abdominal pain after consuming milk or dairy products. For adults who experience lactose intolerance, lactase enzyme supplementation can be an effective solution. The lactase enzyme available in the form of supplements helps in the distribution of lactose during a meal, enabling digestion of dairy products without unpleasant symptoms. This is especially important for people who want to derive health benefits from milk and its products, rich in calcium and vitamin D, without giving up digestion.

Side effects related to lactase - what can they occur and how to deal with them?

The use of lactase, although it is generally safe, can be associated with some side effects, especially in sensitive people. Side effects, however, are rare and usually have a mild character. These include, among others, light stomach ailments, flatulence or allergic reactions that may occur as a result of hypersensitivity to any component of the supplement. If any side symptoms appear, it is worth reduced the dose of the supplement or consult a doctor to choose the right amount of enzyme. People with severe allergies or with chronic diseases should be particularly careful and consult medical advice before the start of supplementation.

Where is lactase? Natural sources of enzyme in the diet

The natural sources of lactase in the diet are limited because this enzyme is produced primarily in the body, and not supplied from the outside in traditional food products. However, some products can support lactase activity or replace its function. For example, some fermented dairy products, such as yogurt or kefir, contain live bacterial cultures that can partially spread lactose, facilitating its digestion. These products can be better tolerated by people with lactose intolerance. For people with serious lactose intolerance, natural lactase sources are not enough, which is why it is often necessary to support enzymatic supplements.

The use of lactase enzyme - as it can be used in the context of lactose intolerance

The lactase enzyme is widely used as a means of supporting people with lactose intolerance, enabling them to eat dairy products without digestive ailments. Lactase supplements are available in various forms, such as tablets, capsules or drops that can be added directly to milk. Thanks to this, people with lactose intolerance can enjoy their favorite dairy products, while avoiding discomfort associated with their digestion. The use of lactase can also help in better absorption of nutrients from dairy products, such as calcium, which is especially important for bone health, especially in the elderly or women during menopause.

Summary

The lactase enzyme plays an important role in digestion of lactose, enabling the breakdown of this sugar into glucose and galactose, which are easily absorbed by the body. Lactose intolerance, resulting from lactase deficiency, is a common problem that can lead to unpleasant digestive ailments. Lactase supplementation is an effective solution that allows you to eat dairy products without intolerance. It is worth remembering, however, that although the use of lactase is generally safe, some people may have side effects that should be monitored. Lactase is available in various forms of supplements that can be used before consumption of dairy products, which significantly improves the comfort of life of people with lactose intolerance. Ultimately, lactase not only facilitates digestion, but also supports better absorption of valuable nutrients from milk and its products.
