"Novanoc natural sleep" - Please give me a professional opinion.

Novanoc natural sleep has the status of a dietary supplement. The manufacturer of a dietary supplement cannot legitimately say that its product can cure or prevent disease. Please remember that it is the task of herbal medicines to treat diseases. When looking for information about a good quality preparation, it is worth paying attention to information about the extract included in the preparation. One such parameter is - DER (Drug Extract Ratio). This is a parameter that determines the ratio of the amount used in the extraction process of the substance to the amount of extract obtained. The second important parameter is information on the standardization of the extract for the content of active ingredient(s). Standardized extract – contains an ingredient or several (group) of ingredients with a documented effect, brought to a strictly defined content of active compounds using co-formulant excipients or preparations with a high or low content of active ingredient. So if on the packaging of the product we find information about both of these parameters (DER and standardization), we can be sure that we are dealing with a valuable extract. The above conditions are met m.in.
