The History & Background of Lactase

 

Lactase is an enzyme needed for a specific biochemical reaction in the body, which is the breaking down of lactose, a sugar in milk, and milk products. Lactase splits lactose to create sugars, glucose, and galactose. Some people are said to have lactase deficiency and are called lactose intolerant. This happens when a person’s body doesn’t make enough Lactase. As a result, they are not able to digest milk well. These people tend to take supplemental Lactase to help their bodies break down lactose and tolerate milk; in this method, they can prevent symptoms of lactose intolerance, which include cramps, diarrhea, and gas.

Studies show that a single genetic mutation, especially in chromosome 2, occurred around 4500 BC and seemed to be the root of lactose tolerance. Another modification came from the population of East African Tutsi; however, communities from sub-Saharan African, southern Europe, and people native to America and the Pacific Islands do not posses Lactase into adulthood.

Use in Supplements

Lactose intolerance happens when one’s body couldn’t produce enough lactase enzymes. One way to treat such conditions is to avoid milk/dairy products. As a result, the body would lack essential nutrients and vitamins such as calcium, vitamin D, riboflavin, and protein. People with low lactase enzyme can usually tolerate only small amounts of milk products, up to 2-4 ounces and get symptoms after a large intake of 6 ounces or more. Taking lactase enzyme with milk products as directed helps prevent signs of lactose intolerance such as cramps diarrhea and gas. Lactase is usually taken after consuming lactose or can also be added to milk. Lactase catalyzes the chemical breakdown of lactose (milk sugar) into galactose and glucose.

A lot of bodybuilders are lactose intolerant, but that doesn’t mean that they have to sacrifice the benefits of dairy. Taking lactase enzymes just before consuming dairy could help ensure that all the nutrients wind up in muscles. Several clinical trials on lactase enzymes show a significant increase in lactose digestion. Now, even those who are considered lactose intolerant positively can consume dairy products with the help of lactase enzyme supplements.

Common Dosing

For those suffering from lactose intolerance, the typical dosage of Lactase is 6000-9000 IU, a tablet at the start of a meal that contains lactose is taken orally. A solution of 2000 IU added to 500 mL milk before drinking it has also been used.

Lactase could be taken in many forms, typical tablets, or even chewable tablets. For people with different health conditions, it is recommended to consult the experts first before taking it.

Potential Side Effects of Lactase

The lactase enzyme has very few side effects. So far, there were no complaints regarding this ingredient. It is rare to experience a severe allergic reaction with this ingredient; however, one must still stay cautious in taking lactase enzymes. If rash, itching/swelling, dizziness, and trouble breathing occurs, it is recommended to ask for medical help.

Although there were no reported side effects for the lactase enzyme, it is still best for pregnant and lactating mothers to avoid taking this ingredient.

FAQs

Q: What are Lactose and Lactase?

A: As a sugar, lactose is part of the carbohydrate family. It’s relatively small and simple compared to the other carbohydrates, but not quite simple enough. Each molecule of lactose is made by joining two simpler sugars, glucose and galactose. Digestion makes the lactose usable in the body by splitting it back into these parts. Digestive enzymes are named for the molecule that they specifically target — that’s why lactose’s enzyme is called Lactase. No other enzyme will digest lactose.

Q: When Do Most People Stop Producing Lactase?

A: Lactase is the last intestinal enzyme to develop and is present in the smallest quantities. Hardly surprising then to learn that it is also the first to go. Generally speaking, those populations with the highest percentage of LI among adults will again lose their Lactase at the youngest age. A few may even start losing it in their first year of life. Many more will keep their Lactase high through age five (i.e., after weaning) and only then see a drop. In others, lactase production may fall very, very gradually throughout life so that symptoms from milk will not be noticed until adulthood. A few people have first reported lactose intolerance in their seventies. And many people keep producing sufficient Lactase and never have LI at any time in their lives.

Q: Lactose Intolerance – How many Lactaid or Lactase pills do you take before eating dairy?

A: I take five before beginning to eat dairy and still have occasional problems. Thanks

Studies

A study on lactase deficiency was conducted on 104 American Indians and two white subjects in 19 families. The issues were considered deficient in Lactase if breath-hydrogen excretion exceeded 0.20 ml per min above fasting at 2 hr after a lactose load of 2 g per kg of body weight (maximum 50 g). 71% of the males and 75% of the females were Lactase deficient. In three families in which both parents were Lactase familiar, 40% of the children were Lactase low; and in the three families with one parent lactase normal and the other Lactase insufficient, 65% of the children were down in Lactase; and finally, in the seven families with both parents Lactase deficient, 93% of the children were Lactase low. The results suggest that this trait shows an autosomal-recessive pattern of inheritance in the distribution of lactase deficiency in the families. The autosomal-recessive pattern of inheritance is one of the several ways for a trait to be passed down through families.

Another study was conducted on some dietary factors and cancer risk. Mendelian randomization has been suggested as a way to overcome confounding by exploiting the random allocation of alleles from parents to offspring. In mid-2006, the authors conducted a study of allele frequencies for lactase (LCT) and taste receptor, type 2, member 38 (TAS2R38) genes that include 634 volunteers (1992-1998) from the Italian branch of the European Prospective Investigation into Cancer and Nutrition. The authors hypothesized a lower milk intake among the carriers of the LCT CC genotype and different information on cruciferous vegetables among carriers of the TAS2R38 variant. Overall, the frequency of the LCT L allele was higher in northern Italy than in southern Italy. Food intake was associated with gene variants. An association was evident for ice cream and LCT variants (p=0.004), less so for milk intake, the TAS2R38 variant showed a graphic gradient and an association with cruciferous vegetable intake. The result of the study suggests that both LCT and TAS2R38 are good candidates from Mendelian randomization studies about cancer and other health outcomes.

Final Review of Lactase

Dairy products are essential to the human body, and it gives various health benefits. Milk is a significant source of calcium, and a lack of calcium can develop weak bone, which we call osteoporosis. In the bodybuilding industry, milk is also needed. Milk consists of 20% whey protein and 80% casein protein. The benefits of whey in the bodybuilding industry have been known for years. Whey is second to whole egg protein in quality and digestibility, which makes it a top choice for many athletes.

Since taking dairy products will be hard for all of those with lactase deficiency, I strongly recommend this ingredient for everyone and not just athletes and bodybuilders since milk or any other dairy product isn’t limited to a specific group of people only. Taking this ingredient will help those with lactase deficiency break down lactose and tolerate milk and still not miss out on the essential health benefits that it gives to the human body.
