Despite all the precautions we have described, it still is possible that, after a long period of time, the contents of certain vitamins may be reduced below the original formula.
Indeed, factors such as storage condition, heat, and humidity can contribute to the natural instability of certain vitamins.

WITH TWYDIL®, PRODUCTS ARE CONFORM TO THE LABEL CLAIM UNTIL BEYOND THE EXPIRY DATE.

To assure that we reach that goal, we have established a quality control procedure in which we analyse samples of all our products every 6 months, from their production until their expiry date.
If analysis shows that even a single one of the active substances of the product does not conform to the label, the stock is immediately withdrawn from the sale.
Taking into account the labile nature of certain vitamins, it’s a challenge that required the highest standards at every step of the production.

It’s only because of the extent of all these precautions that TWYDIL® is able to guarantee the vitamin contents of its products.
