  • How to choose between Lactolerance 1Day, 4500 and 9000?

    A daily capsule of Lactolérance 1Day protects 24 hours a day, whatever the level of intolerance.
    One capsule of Lactolérance 4500 (moderate intolerance) or 9000 (severe intolerance) protects for 45 min to 1 hour.

    For the first use we recommend Lactolérance 9000, because it is effective immediately, from the first use.

    If the experience is positive, try Lactolérance 1Day, effective after an adjustment period of about a week. During this period, we recommend the association of Lactolérance 1Day with Lactolérance 9000.

Since I take a single 1Day capsule, no more worries when consuming a dairy product and no more having to walk around with capsules just in case. One a day and everything is settled.

My 16 year old son has been lactose intolerant for many years thanks to the "lactolerance" products, he can afford to deviate from his lactose free diet. The products are very effective and the site very serious. Thanks to Lactolérance!
