Green tea, L-carnitine and choline complex is suitable for periods when you want to support metabolism during a regular working day – typically with a sedentary routine, irregular movement or fluctuating energy levels.

In practice, take 2 capsules in the morning and 2 capsules at midday, always after meals and with a sufficient amount of water.
