Whether a health product can be used long-term depends on several key factors:

Situations where long-term use is possible:

**Safe and necessary ingredients:** If the health product's ingredients are natural and mild, with no obvious side effects, and you genuinely need long-term supplementation or regulation based on your own health needs—for example, some essential vitamins that the body cannot synthesize (such as vitamin C and vitamin D)—and dietary intake is insufficient, long-term appropriate supplementation at recommended doses is acceptable.

**Reliable and guaranteed quality:** If the product comes from a reputable manufacturer, the production process strictly adheres to relevant standards, the quality is stable, and it has undergone long-term market validation and positive user feedback without any safety issues, then long-term use is relatively reassuring.

Situations where long-term use is not recommended:

**Potential risks associated with ingredients:** Some health products may contain irritating or toxic ingredients. Even if they may have some short-term effects, long-term use may harm the body. For example, some products containing hormones may disrupt the body's natural hormonal balance with prolonged use.

**Dependence:** Some health products may cause dependence. Once you stop using them, you may experience adverse reactions or a decline in your original bodily functions. In such cases, long-term use is definitely not recommended.

**Changed needs:** As your physical condition changes or your lifestyle adjusts, the health needs you previously required may no longer exist. In this case, you should stop using the corresponding health products.

Therefore, when deciding whether to use health products long-term, careful evaluation is essential, and it is best to do so under the guidance of a doctor or professional health expert.
