Question one: standard

Basically this GMP (Good Manufacturing Practice) is applicable for everything, including medicines and food.

This standard should ensure a high level of product quality and ensure that the formula of the product manufactured is as declared, the product does not contain impurities, there is an appropriate labeling, the product is suitably packaged, it will not lose its properties over its expiration date.

That is, you are not poisoned by salts of heavy metals, phenols and other organics, but there is nothing about the USE. But this is not a POISON.

Вопрос второй: чем пищевая добавка отличается от лекарств и зачем их принимать

• according to the rules, the content of the active substance in it should not exceed the therapeutic dose (for example vitamins), and if they are obviously in a low dose, then why take them?
• "unique formula", ok, we agree, although confirmation would be needed, both of its uniqueness and effectiveness. And were her clinical trials? With drugs, these are complex and very expensive sequential trials. At a cost they are available only to large concerns. And without performance tests, you can sell according to the GMP standard
• everyone needs vitamins! Are you sure about that? Vitamins are primarily catalysts, including oxidative processes. Are you in a hurry? Are you in a hurry to grow old? In order to avoid vitamin deficiency, just good, versatile nutrition with fatty fish, a small amount of meat, vegetables and fruits is enough. Only professional athletes with a tremendous expenditure of all body forces, including protective ones, and a strong drop in immunity at the height of the peak of a sports form need such support. And it has nothing to do with health, it is a side problem of hard work!
• Omega 3, .. to everyone from the heart. Have you been to the doctor on this topic? Anlisa done, atherosclerotic index known? Or just "for health"? I spoke with a gastroenterologist who daily looks through the fiber optics into the stomach and intestines of the examined patients. Often, a mucosal sample is taken for histological examination. He told me: "... after taking the tissue for examination (a tiny piece), it hurts and bleeds, you have to cauterize, .. you ask later - the answer is: accepts omega ..." How to evaluate it? If this is a drug course of blood thinning, the patient passes a blood test almost constantly. Will blood get thinner from omega is that bad? It is difficult to say that a thrombotic stroke is less likely, while hemorrhagic is more likely. Better all the same, without amateur performances and under the control of laboratory examinations. Although children fatty acids for the development of the brain and nervous system are quite shown.
• with which I am immediately ready to agree - with a lack of trace elements. This is fundamentally important. But you also need to understand the mechanism of their absorption. If you do not have enough calcium, there is no point in chalk, only a slightly lighter stool can be. Trace elements are well absorbed only in the state associated with the organic matter, either the chelate form (amino acid salts) or the colloidal form. Especially athletes, women and the elderly need them. The most important thing is the choice of supplier. It is better to use well-known brands and order in their online stores.
