Ecological packaging

Since the beginning of the IAFSTORE® Rebranding we have reasoned with a view to sustainability, both in terms of product and packaging and packaging, and the new paper pack marks for us the achievement of an important goal. The envelope is made entirely of paper and can be recycled by throwing it in the special waste collection containers.
This is only the first step of a great eco-sustainability project. IAFSTORE® by 2023 has the ambitious goal of completely eliminating plastic from its entire supply chain.
Why does the product packaging seem worn?

In line with the company values and the commitment to protect the environment, we have started a process of reducing plastic from the packaging of our products, favoring a totally disposable packaging with paper and we aim to do so on all our production in the next period. .
The low weight of the material and the reduction of plastic substances could lead to a lower adhesion of the printing colors and more easily expose the package to wear. We have studied packaging that protects the quality of the food and guarantees the safety of our products.
We recommend to always store in a cool, dry place away from heat sources and direct light.

Why is there no measuring cup inside the package?

We care about the health of our planet, we are starting a process of reducing plastic both from the packaging and from the accessories of our products.
Join us in this important journey by dosing the contents with a normal spoon or with the kitchen scale.
DIRECTIONS: add 30 g of product (3 tablespoons) in 300 ml of water and take once a day.


STORAGE: keep tightly closed in a cool and dry place
