Cozidase makes me nauseous. Is that possible?

Our lactase capsules and tablets are safe to use several times a day. We do recommend that you stick to the maximum set 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.

If you have a lactose intolerance there are a number of options from which you can choose. Below, we briefly explain which product is suitable for various requirements. More information can be found on the product page of the relevant product. Lactase 2500 - our lowest dose, for a low degree of intolerance or when consuming small amounts of lactose. A small, easy to swallow tablet that is also ideal for children. Lactase 3000 - our standard capsules, to be used for a lower degree of intolerance or smaller amounts of lactose in the diet. Lactase 10,000 - our relatively high-dose capsules, ideal if you are sensitive to lactose or want to consume larger amounts of lactose. Lactase 20,000 - our strongest option, ideal for high levels of intolerance or when consuming large amounts of lactose. In addition, it is convenient to use because the tablets are breakable. Our lactase drops can be used to make your own liquid (sweet) dairy products lactose free, such as milk, cream or custard. Useful for cooking or baking. Our product once a day does not contain the lactase enzyme, but a combination of 6 specially selected lactic acid ferments, lactase precursors. Due to the fact that only one capsule per day needs to be taken, this is the most convenient solution.

Many of our products have a recommended dosage of 1 to 2 breakable tablets, 1 to 3 capsules, or even 1 to 4 tablets. We recommend starting with the highest dose, to see how you react, and then tapering down to a smaller dose next time. You can do this until you can see the minimum dose your body needs to avoid triggering the symptoms of your food intolerance. Of course, what you eat/drink and portion size will matter (as will the severity of your intolerance), but the general rule is that by starting high, you can tell more easily, if the product is helping you or not, rather than not being sure if it was enough. It is certainly helpful to taper the dose and see if you can go to a lower strength next time. Overdosing does not have any negative effect and is therefore not a bad thing. In some cases it is better to be on the safe side in order to avoid unnecessary complaints.

Yes, that is possible. Cozidase is high in copper and zinc. Taking Cozidase on an empty stomach can cause nausea. We therefore recommend always taking the capsules with a meal. If the complaints persist: take 1 capsule a day instead of 2 capsules.

No, we strongly recommend not to do so. Cozidase contains, among other things, copper, zinc and vitamin B6. If you ingest too much of these, you may experience side effects, such as severe nausea. Always stick to the recommended daily dosage of 2 capsules a day and do not take more than 2 capsules.

No. Cozidase does not contain Diamine Oxidase at all. Cozidase provides the building blocks for the body to make its own Diamine Oxidase.

Our DAO mini tablets can be taken several times a day. We do recommend that you stick to the maximum number of capsules per day. For the DAO mini, the maximum is 1 capsule per meal 3 times a day.

DAO includes products containing the Diamine Oxidase enzyme. The DAO mini tablets contain only the Diamine Oxidase enzyme (DAO). The DAO Plus capsules contain Vitamin C and Quercetin in addition to the Diamine Oxidase enzyme.

The amount of the active Diamine Oxidase enzyme is the same in both products, 20,000 - 30,000 HDU per tablet/capsule. If you want to use only the Diamine Oxidase enzyme, you should choose the DAO mini tablets. These are easy to swallow (5mm diameter). If you also want the benefits of the additional active ingredients Vitamin C and Quercetin, choose the DAO plus. If would like to spread out the quantity of DAO enzyme during your day then it's possible to open up your recommended dose of 3 capsules and just take the small beige DAO tablets multiple times a day. That way you can still adhere to the maximum dose of 3 capsules a day but are able to take smaller dosages of the DAO enzyme.

Our DAO capsules are safe to use several times a day. We do recommend that you stick to the maximum set number of capsules per day. For DAO plus, this is a maximum of 1 capsule per meal for a maximum of 3 times per day.  

Yes, you certainly can. The convenient thing about DAO Plus is that it contains capsules with 4 tablets in each capsule. 2 white/beige tablets with 20,000 - 30,000 HDU of the enzyme Diamine Oxidase, 1 green tablet with 38 mg Quercetin and 1 brown tablet with 20 mg Vitamin C. If you don't want to take Quercetin, but still want to use DAO Plus, you can remove the green tablet with Quercetin from the capsule. You can also choose to use the DAO mini tablets, which only contain the Diamine Oxidase enzyme (DAO) and no Quercetin is added.

If you use the once-a-day product you can, in theory, properly digest all the lactose you ingest in a day. In some cases, for example if you are very sensitive to lactose, it may be necessary to take a lactase capsule or tablet to digest large amounts of lactose. However, for most people this is not necessary and the once-a-day is sufficient to properly digest all lactose during the day.

The "once a day" needs some build up of time to have the full effect when used for the first time. This is because the probiotics need some time to build up in the intestines. This takes about 5-14 days after the first use for most people. The effect of the once a day will continue as long as you take a capsule daily.

Feel free to use the "once a day" capsules for a long time, as this does not result in any disadvantages or side effects. Many of our customers have been using this product for years with positive results. You can also choose to use this product temporarily, for example during a holiday. If this is the case, please take into account the build-up period of 5-14 days after the first use.

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.
