                                According to nutritional data, pumpkin seeds are one of the richest sources of L-arginine, containing over 5 grams per 100g serving. While technically seeds, they significantly outperform true nuts in this category, making them a key consideration when asking which nut has the most L-arginine. Following pumpkin seeds, peanuts and almonds are among the nuts with the highest concentrations of this important amino acid.
