Frequently Asked Questions
Metis Sleep & Nervousness Duo is suitable for anyone who has trouble sleeping due to worrying, stress or underlying tension. Whether you have trouble falling asleep, sleeping through the night or not waking up refreshed. Metis helps you with this and supports your body in the way you need.
Compared to many other products, Metis formulas often contain a higher dose (the number of mg) of ingredients with more active substances (e.g. the % Valerenic acid). In addition, our formulas not only contain completely natural ingredients, but also the necessary co-factors for optimal absorption and processing of the main ingredients.
No, Metis Sleep 08 is a natural and freely available nutritional supplement. The formula supports you in sleeping better and falling asleep faster by supporting the body in a natural way.
The Metis Sleep & Nervousness Duo has been specially formulated to provide complete support to the body. Metis Anti-Stress 03 reduces the impact that stress has on your body, as stress is one of the biggest causes of poor sleep quality. The body cannot fully relax and worrying can make it difficult for you to fall asleep. That is why it is important to reduce the impact of stress and then allow the body to completely relax.
No problem. All Metis formulas have been specially developed to be used together when you take the recommended dose.
If you want to use Metis supplements in combination with a chronic condition, the use of medication and/or therapies, we would like to recommend that you first discuss this in detail with your treating physician. This person has a better idea of your medical history and will therefore be able to provide appropriate medical advice.
The formulas are effective from day one. However, for optimal effect, it is best to use the formulas for a longer period.
Safe supplements, produced in Belgium and of pharmacist quality
Metis is different from other supplement brands. Many brands in the industry use minimal amounts of an ingredient, purely to capitalize on the fame of that specific ingredient. They do not guarantee that the ingredient used represents the active part of the plant.
Take Valerian as an example: the real power of Valerian comes from the Valerenic acid in the plant, not from the leaves. Although both parts come from the same plant, there is a significant difference in how they work. At Metis we ensure that we use therapeutic doses that are scientifically substantiated, rather than lower amounts purely for marketing purposes.
