Phospholipids
Essential components of cell membranes, crucial for brain health, liver function, and nutrient absorption.
Also known as: Phosphatidylcholine • Phosphatidylserine
Overview
Phospholipids are a class of lipids that are a major component of all cell membranes. They are composed of a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. This structure allows them to form a lipid bilayer, which is the basic framework of all cell membranes. Phospholipids are essential for brain health, liver function, and the absorption of nutrients.
Key Benefits
Supports Brain Health
Phosphatidylserine is a key phospholipid in the brain and has been shown to improve cognitive function, memory, and focus.
Promotes Liver Health
Phosphatidylcholine is important for liver function and can help to protect the liver from damage.
Enhances Nutrient Absorption
Phospholipids can help to improve the absorption of other nutrients, such as curcumin and milk thistle.
