Introduction
For infants, the elderly, or individuals with weakened immune systems, milk formula fortified with lactoferrin can provide certain supportive benefits. As a natural component, lactoferrin helps regulate the activity of immune-related cells. Combined with the nutritional content of the formula, it supports the body's immune function, making it especially suitable for these populations who may lack sufficient lactoferrin intake through their regular diet.

Generally, lactoferrin-enriched formula milk may have a supportive effect on the immune system for specific populations, but its benefits are limited for individuals with normal immune function. If in doubt, it is advisable to consult a healthcare professional in advance. The detailed analysis is as follows:

For infants, elderly individuals, or those with weakened immunity, lactoferrin-enriched formula milk can provide certain supportive benefits. As a natural component, lactoferrin helps regulate the activity of immune-related cells. Combined with the nutritional content of the formula itself, it supports the body's immune function and is particularly suitable for these groups who may lack sufficient lactoferrin intake through regular diet.

For healthy adults with normal immune function, the effectiveness of lactoferrin-enriched formula milk in boosting immunity is limited. These individuals typically meet their basic nutritional needs through daily diet, and their immune systems are already stable. Additional lactoferrin supplementation is unlikely to produce noticeable effects, so there is no need to rely on such formulas to enhance immunity.

When choosing lactoferrin-enriched formula milk, individuals should consider their own health conditions and should not regard it as a therapeutic product for medical conditions. If any immune-related issues arise, prompt medical consultation is recommended to determine the underlying cause, avoiding excessive reliance on nutritional supplement formulas.
