FAQ about lactase tablets and capsules
Many of our products have a recommended dosage of 1 to 2 break tablets, 1 to 3 capsules or even 2 to 4 tablets. We recommend starting with the highest dose, to see how you react, and then reduce to a smaller dose the next time, to find your own ideal dosage.
You can safely use our lactase capsules and tablets several times a day. We do recommend that you stick to the maximum number of tablets or capsules per day. For the lactase 2500 this is a maximum of 20 tablets per day, for the lactase 3000 and lactase 10,000 this is a maximum of 15 capsules per day. For the lactase 20,000, the maximum is 10 tablets per day.
With the lactase tablets and capsules, we have different strengths available. This strength is expressed in FCC per capsule. You can choose from 2500, 3000, 10,000 and 20,000.
If it is your first time trying one of our lactase products, we generally recommend trying one of the higher strengths first, for example the 10,000 or 20,000. Starting higher will give you a clearer indication of whether it will work well for you or not when you first try it. At a lower dose, it may be unclear if it helps or not, or it maybe that the dose wasn't high enough.
If you have a milder degree of intolerance or only want to use the capsules or tablets for smaller amounts of lactose, you can choose the 2500 or 3000 strength - depending on whether you prefer to swallow a small tablet or a capsule. If you are more sensitive to lactose or want to consume larger amounts of lactose you may want to choose the 10,000 or 20,000.

If you have trouble digesting lactose, there are a number of products that can help. Below, we briefly explain which product is for which purpose. More information can of course be found on the product page of the relevant product. Lactase 2500 is our lowest dose, for example, for smaller quantities of lactose. A small easy-to-swallow tablet that is also ideal for use with children. Lactase 3000 are our standard capsules, for use with smaller quantities of lactose in the diet. Lactase 10,000 are our relatively high-dose capsules, ideal for larger quantities of lactose. Lactase 20,000 is our strongest option, ideal for large amounts of lactose. It is also convenient for dosing as the tablets are breakable. You can use our lactase drops to make your own liquid (sweet) dairy products lactose-free, such as milk, whipped cream or custard. Convenient for cooking or baking.
Many of our products have a recommended dosage of 1 to 2 break tablets, 1 to 3 capsules or even 2 to 4 tablets. We recommend starting with the highest dose, to see how you react, and then reduce to a smaller dose the next time, to find your own ideal dosage.
FAQ about lactase drops
You can use the lactase drops for making various liquid (sweet) dairy products, lactose free. Depending on the amount and consistency of the product, you can add a number of drops. After 24 hours, 80% of all lactose in the product has been broken down.
Products that you can make lactose free using the drops include:
Milk (5 drops per litre)
Chocolate milk (5 drops per litre)
Coffee milk (5 drops per 250 ml)
Whipped cream (5 drops per 250 ml)
Cooking cream (5 drops per 250 ml)
Condensed milk (10 drops per 250 ml)
Mascarpone (10 drops per 250 ml)
Cream cheese (10 drops per 250 ml)
Unfortunately, the drops are not resistant to an acidic environment and therefore they are not suitable to make acidic dairy products such as yogurt, cottage cheese, sour cream, crème fraîche or buttermilk lactose free. However, you can take a lactase tablet or capsule to still be able to properly digest all lactose.
Add the required number of drops to the dairy product. Make sure the drops are mixed well into the dairy product by shaking or stirring well. Then leave it in the refrigerator for at least 24 hours. After 24 hours, at least 80% of all lactose will have been broken down. If you would like a completely lactose free dairy product, add more drops or leave it for longer in the refrigerator before use.
FAQ about once a day
