The invention relates to a capsule with controlled release of the active substances and to a process for preparing the same. The claimed capsule comprises a body (1) and a cap (2), being provided with 1...5 impervious separating walls (3, 4, 5, 6, 7), having a wall thickness of 0.02...0.18 mm, containing 2...6 natural or synthetic active substances, the body (1) and the cap (2) are joined, the joint being insulated with a tape (8). The claimed process consists in introducing a first active substance into the capsule body, after which the first impervious separating wall is positioned into the capsule body forming a first layer therein, the other layers of active substances are similarly formed in the capsule body, having different release times, after which layers of active substances are similarly formed in the capsule cap, then the cap is joined with the capsule body on an area of 0.5...3.5 mm, upon which a tape sealing and consolidating all the circumference of the joint is applied.
