Basically, it is the inability of the body to digest lactose

As with most nutrients in food, lactose must be split into smaller units before the body can properly absorb it. Our bodies make special substances - called enzymes - that help break down the food. The enzyme which acts specifically on lactose is calledlactase. Some people don't produce enough lactase enzyme, so the lactose in their food is not properly broken down, and the undigested lactose goes on to cause troublesome symptoms.
We all know that milk is good for us; it contains protein, fats and carbohydrates, as well as vitamins and minerals, and gives us much of the calcium wwe need.

In milk, the carbohydrate comes in the form of a special type of sugar - lactose, or milk sugar; it is this that gives milk its delicate sweetness. Many people, however, cannot digest lactose properly and this condition is known as "lactose intolerance".
Here is a checklist of the usual symptoms. If you find you can tick most of them - and that they are always brought on when you have milk in one form or another - it may be that you are lactose intolerant.
Feeling sick
Stomach discomfort
Bloated feeling
Cramping pain
"Wind" or flatulence
These symptoms may vary in severity according to how much lactose you have had. Some sufferers can tolerate the equivalent of up to about half a pint of milk without too much trouble. Only when you exceed your limit - maybe by eating something you didn't realise contained lactose - does the trouble start.

There is no hard and fast rule on how soon symptoms appear after eating lactose-containing foods. The feeling of sickness and stomach discomfort can appear after only five minutes, whereas other symptoms may take a few hours to develop.

If symptoms are persistent or particularly severe, or if they occur independently (that is, when you haven't had any lactose) you should seek medical advice.
There are two ways lactose intolerance can develop. It can be an inherited condition (which, rarely, may be present at birth, but usually shows up during childhood or later), or it can be triggered off by illness – which affect the digestive system.

Lactase is a very sensitive enzyme and is easily affected by such illness. It usually returns to former levels after the person has recovered - but sometimes not for quite a while - so the lactose intolerance is only temporary.

Occasionally, however, the affected part of the intestines may be more severely damaged and intolerance to lactose will be permanent.

The following conditions may cause lactose intolerance:
Irritable bowel syndrome
Duodenal ulcer
Coeliac disease
Sensitivity to gluten in wheat, etc
Vitamin B2 (riboflavin)
Deficiency disease
Ulcerative colitis
Cystic fibrosis
Certain tropical diseases - e.g. cholera, sprue
Temporary lactose intolerance can also be caused by certain medicines, some antibiotics, and those drugs used to treat arthritis, can temporarily upset the digestive system and reduce levels of the lactase enzyme.
The lactase enzyme in Milkaid® is extracted from natural yeasts and is totally harmless.
Lactase treated milk is exactly the same nutritionally, only the form of the milk sugar (lactose) has been altered and the milk will taste slightly sweeter.

Milk treated with lactase enzyme can be used in exactly the same way as you would use ordinary milk, in beverages, cooking, making yoghurt, ice cream - or just straight from the bottle. It doesn't matter whether the milk is full fat, skimmed, or "long life" - all can be effectively and safely treated and without fear of triggering unpleasant symptoms
Yes! Once your child starts drinking cow's milk.

Just like adults, the amount of lactase children produce varies. So, we suggest you start by giving them milk with all the lactose removed, then reduce gradually to a level that suits them.
Yes, Milkaid® Tablets are raspberry flavoured caplets containing lactase enzyme. They are intended to be chewed or swallowed immediately before consuming any food, which may contain lactose. They are ideal and convenient when eating pre-prepared foods, at home, in restaurants or on holiday.
Approximately 5 million people in the UK experience stomach cramps, bloating, wind or diarrhoea after consuming milk or dairy foods. The lactose (milk sugar) which is found in all dairy products is often the cause. This common problem, known as Lactose Intolerance occurs when the body produces insufficient amounts of the enzyme needed to help digest lactose.
Milkaid® is a dairy digestive supplement that makes milk and dairy foods digestible. Milkaid® is a safe, natural enzyme like the one your body makes. With Milkaid® you can naturally enjoy dairy foods such as milk, cheese and ice cream again. Lactose can be found in various other foods and a list is available here.
