– Growth hormone regulation
– Neuroendocrine system function

## Dietary Sources of Aspartic Acid

Aspartic acid is found in various protein-rich foods, including:

– Animal sources: beef, poultry, eggs, and dairy products
– Plant sources: soy products, lentils, peanuts, and almonds
– Supplements: available as standalone amino acids or in protein blends

## Safety and Considerations

While generally safe, individuals should consider:

– Typical dietary intake is sufficient for most people
– Possible interactions with certain medications
– Potential side effects with excessive supplementation
– Consultation with healthcare providers before taking supplements

## Conclusion

Aspartic acid serves as a multifunctional amino acid essential for numerous physiological processes. From supporting brain function to enhancing energy production and athletic performance, this important nutrient contributes significantly to overall health. While most individuals obtain adequate amounts through a balanced diet, understanding its functions can help optimize nutritional choices for specific health goals.
