Research related literature: You can know whether health care products are really effective by reading relevant scientific research and medical literature. If these documents do not mention the benefits of this product, it is likely to be false propaganda.
Seek professional advice: seek advice from a doctor or pharmacist and ask them what they think of this health care product. They can tell you whether there is enough evidence to support the effectiveness of the product.
Compare different brands of health care products: understand the ingredients and functions of different brands of health care products and compare their advantages and disadvantages. If a brand claims to be "unique" or "magical", then they may just use marketing strategies to attract consumers.
Pay attention to the difference between food and medicine: health care products are usually food rather than medicine, and do not need to go through strict drug approval procedures. This means that they don't need to prove its effectiveness and security, so it is difficult to prove their scam.
In short, to prove that some health care products are deceptive, comprehensive analysis and research are needed. It is necessary to understand the composition and function of health care products, study relevant literature, seek professional advice, compare different brands of health care products, and pay attention to the difference between food and medicine.
