Lactase tablets and lactase drops contain the same type of digestive enzyme, but they are designed for different routines. The useful question is not simply “which is stronger?”—it is where the lactose is, when the food will be eaten and whether you want to treat the food or take lactase with the meal.
What lactase does
Lactose is the natural sugar in milk and many dairy foods. The small intestine normally makes lactase, an enzyme that breaks lactose into smaller sugars for absorption. When lactase activity is lower, undigested lactose can reach the large intestine and contribute to symptoms such as bloating, wind, abdominal discomfort or diarrhoea.
Healthdirect and Dietitians Australia both emphasise that tolerance varies. Many people do not need to remove every lactose-containing food; the amount and type of food, portion size and individual tolerance all matter.
The practical difference
| Format | Best suited to | How it fits the routine |
|---|---|---|
| Lactase tablets | Meals, snacks and drinks containing lactose, including mixed or acidic foods | Taken at the time directed on the product label, immediately before the lactose-containing food or drink |
| Lactase drops | Suitable dairy liquids or cream | Added directly to the food or drink according to the product directions; some uses involve refrigeration before consumption |
The format does not change the underlying issue being addressed: both supply lactase for lactose. What changes is whether the enzyme is used with the meal or added to a suitable dairy liquid.
When tablets may be the simpler option
Tablets are often the more flexible choice when the lactose is part of a mixed meal—for example, café food, a creamy sauce, ice cream, yoghurt or dessert. They are also useful when you cannot prepare the food in advance or do not know exactly how it was made.
For the Intoleran Australia range, Lactase 20,000 tablets are taken immediately before a meal or drink containing lactose, following the pack directions. The scored tablet allows the labelled serving to be adjusted within the stated directions.
When drops may be more convenient
Drops can be useful when you regularly prepare milk, cream or another suitable dairy liquid at home. Rather than taking a tablet with each serve, you treat the liquid according to the directions for that product.
Intoleran Lactase Drops can be stirred into suitable milk products for immediate use or added to a larger quantity and refrigerated for the directed preparation time. The current product directions state that the drops are not suitable for acidic products such as yoghurt and buttermilk; a tablet or capsule format is the more appropriate option for those foods.
Five questions to help you choose
- Is the lactose in a liquid you control? Drops may suit milk or cream prepared at home; tablets are usually easier for restaurant meals and packaged foods.
- Will you eat it now or later? Tablets travel with the person, while drops can be used to prepare suitable liquids ahead of time.
- Is the food acidic? Check the drop directions carefully. Some acidic dairy foods are not suitable for this format.
- How much lactose is in the serve? A splash of milk and a large milkshake are not equivalent. Follow the specific product directions rather than assuming one amount suits every meal.
- Is the issue lactose intolerance or milk allergy? Lactase does not make milk safe for someone with a cow’s-milk protein allergy.
Keep nutrition in view
Dairy foods can contribute calcium, protein and other nutrients. If you reduce dairy substantially, choose suitable fortified alternatives and review the overall diet rather than focusing only on symptom avoidance. An Accredited Practising Dietitian can help identify a nutritionally adequate approach that reflects your individual tolerance.
When to seek advice
See a GP or qualified healthcare professional if symptoms are new, severe, persistent, associated with weight loss or bleeding, or occurring in a young child. Other gastrointestinal conditions can cause similar symptoms, and self-diagnosis can delay appropriate assessment.
