Phosphatidylserine is a naturally occurring phospholipid found in food, especially in animal brain tissue and some plants.
Phosphatidylserine is mainly found in animal brain tissue (especially bovine brain and chicken brain) and in some phospholipid-rich plants, such as soybeans, fish, especially deep-sea fish, which are also thought to contain some amount of phosphatidylserine.
Phosphatidylserine is usually found in foods along with fats, so consider eating foods that contain phosphatidylserine with some healthy fats, such as olive oil, nuts, avocados, etc., to promote absorption.
In addition to animal brain tissue, some plants provide foods that also contain lecithin, which includes phosphatidylserine. Soy lecithin is one of them**, so increasing your intake of soybeans and their products (e.g., tofu, soy milk) may also help with phosphatidylserine.
To ensure adequate phosphatidylserine intake, it is recommended to maintain a varied diet that includes a variety of foods of animal and plant origin.
Food intake of phosphatidylserine may be subject to individual dietary preferences, dietary constraints, and dietary culture, but supplementation may be considered as a nutritional supplement if there are specific health needs or phosphatidylserine supplementation considerations, but consult a physician or healthcare professional for advice to ensure safety and appropriate dosage.
