Confusion about the recommended dose of the inability to unequivocally established on the basis of standardized experiments carried out on humans. Yet there are some constraints, provided either by specific laws or decrees that a lack of information and accurate data are the result of informal discussions among experts, representative bodies authorizing the sale of food supplements and representatives of drug companies.
All too often, the consensus of stakeholders is helpful to manufacturers of supplements. On the other hand, I understand the concerns of the approval authorities, due to difficulties in determining the minimum objective and on the other side, meanwhile the maximum "safe" daily dose of tens if not hundreds of dietary supplements and natural substances, the more complex supplement. The recommended dosage stated by the manufacturer, it is mostly just speculation or is the result of a "comparative analysis", possibly based on scientific studies. Approval Body has the task to consider whether there are grounds for adjusting the dosage, and always "downwards".
I am convinced that most supplements, when used in amounts recommended by the manufacturer and approved by the Ministry, is completely safe. On the other hand, in most cases, the approved dose so small that the consumer can not feel any effect (if it does not produce well-known "placebo effect"). The problem is solved by using the additional benefits that can be specified in the instructions accompanying the product or its label.
It is to the detriment of the user who calls the product a distinct and specific effect. It is even more surprising is that many users subconsciously rejects supplements increased benefits for fear of side effects. But this is in place! This negative attitude is caused by the warnings of specialists from the already mentioned "the adverse consequences of consuming supplements. I can not exclude the influence of other effects, and emphasizing the negative effects of medication. A possible additional factor is the economic performance accessories, the more consumed in higher doses. Firefox is not reimbursable by health insurance.
The situation becomes apparent when compared with medication. In the case of medicines with the doctor, the patient will never discuss the legality of the drug and the dose chosen, let alone their fear of possible side effects. When he finds out that his medication "does not do well, rarely complains and does not require its replacement, either because they think that such a procedure is not possible, or doctors fear negative reactions. Only those patients who do not comply with medication, sometimes decide to try a supplement.
