1 capsule per day to be taken each morning with a glass of water, ideally on an empty stomach. You can take them on an empty stomach because our capsule is vegetable and has been designed to dissolve once it reaches the less sensitive areas of your intestine.

Do not exceed the recommended daily dose. Food supplements are not a substitute for a varied and balanced diet.

Our capsules are small and easy to swallow. If you ever have trouble swallowing them, you can open the capsule in half and dilute it in a bit of water or in compote or yogurt.

No contraindication has been found against pregnant women. But we still advise you to consult your doctor to avoid any interaction with another drug.

Yes ! This was one of the important points for us when developing our formulas. Our food supplements are vegan, cruelty free, GMO free, gluten free and its capsules are 100% vegetable.

To be certified organic, a food supplement must contain 95% of ingredients from organic farming. 56% of the ingredients contained in GO FOR DETOX and 67% of the ingredients contained in GO FOR PROTECTION are plants from organic farming.

The rest are probiotics (lactic ferments), vitamins and non-certifiable nutrients. We have favored everything in 1 capsule (probiotics + organic plants) over certification for your daily comfort and savings.

How quickly our food supplements will work depends on each person. Some will see the result in a few days, others in a few weeks. What is certain is that they depend on the regularity with which they are taken. Listen to your body and you will know! Moreover, food supplements are aptly named, they complement a balanced lifestyle. We support you in your change, the more you are involved, the more you will see measurable results.

No, because the strains of probiotics used in our supplements are tyndalised. This means that they have been subjected to a heat treatment which allows them to be “deactivated” without destroying them. This heat treatment is controlled and guarantees the inactivation of the original ferments, in addition to guaranteeing the integrity of the structure of their proteins and their biological properties. Thus, despite the presence of probiotics, it is not necessary to keep the supplements cool.


There are several reasons that can cause oily skin. We therefore advise you to act by elimination / priority:

  • Adopt a healthy and balanced diet (not too fatty or too sweet).
  • Do not strip and dry your skin with products that are too aggressive. These products are only intended to send your skin the signal of dry skin to be nourished with sebum. You understand the problem/vicious circle.
  • Do not neglect to moisturize and nourish your skin. She needs it like all your organs!

=> All DEMAIN products are 100% natural, organic and enriched with prebiotics and probiotics that rebalance the curanic microbiota (the health of your skin). The TOMORROW beauty routine that you can adopt is the following:

  • GO FOR DETOX cure to cleanse your body and therefore your skin from the inside.
  • GO FOR GLOW Gentle Exfoliating Cleanser to purify and exfoliate your skin (and prevent bad bacteria from growing under dead skin).
