2. Seek information from credible sources: Seek information from credible sources, such as medical research reports, nutritionists' suggestions, magazine reports, etc. Ensure that the information comes from trusted organizations or independent third parties, not from product brochures or their affiliates.
3. Study the ingredients and effects: Study the main ingredients, dosage, mechanism and effects of the product. Understand the influence of this ingredient on the body and its reaction to drugs, so as to evaluate whether the product is beneficial to the health of the elderly.
4. Comparison of product effect and cost: Compare with other similar products, and compare their effect and cost. This can help you achieve a more comprehensive understanding. For example, some products claim to use magical ingredients or just some unnecessary vitamin combinations, but in fact, the health care effect is not great.
5. Respect the opinions of the elderly and explain: Finally, you need to respect the autonomy of the elderly and remind them of the risks. Old people may be reluctant to give up using some health care products, but you can help them understand more comprehensively whether these products are really beneficial to their health and provide them with alternative healthy living programs.
