You can take the lactase 2500 tablets prior to any lactose-containing meal. The tablets are the size of a sweetener and therefore easy to swallow. You can take the tablets with some water, for example. The capsules are suitable for use with children (from 2 years of age). After ingestion, the lactase enzyme is active for about 30-45 minutes.
The tablets can be chewed if necessary, but as the tablets are not specifically made for this, it may stick a bit in the teeth. The best option remains to take the tablets with some water without chewing.
