    • Probiotics and prebiotics: Support the health of intestinal microflora, which can indirectly affect metabolism and weight.

  2. The mechanisms of the action of dietary supplements positioned as a means for weight loss:

    Various dietary supplements can act differently, depending on their composition:

    • Fathers: Presumably accelerate metabolism and increase energy consumption, contributing to burning fat. They may contain caffeine, green tea extract, L-carnitine and other components.

It is important to critically evaluate research results and not rely solely on advertising.

  2. Risks and side effects:

    Bades, like any other substances, can cause side effects. Some side effects can be insignificant, such as stomach disorder or headache, while others can be serious, such as an increase in blood pressure, rapid palpitations or allergic reactions.
