Liposomes - Sunflower Lecithin Phospholipids
Liposomes represent an innovative approach to nutrient delivery, with the potential to offer superior absorption - over 8 times more - compared to conventional forms.
They enable higher therapeutic efficacy at lower doses by maximizing absorption and minimizing toxicity.
Liposomal mechanism prevents the degradation of the active ingredients within the digestive system, as often occurs with conventional pill or capsule forms.
Liposomes are tiny spherical vesicles composed of lipid bilayers, which can encapsulate both water-soluble and fat-soluble substances. This unique delivery system is designed to enhance the absorption and bioavailability of the encapsulated ingredients.

The term "lecithin" originates from the Greek word "lekithos," meaning "egg yolk," where the substance was first identified. Plant-derived lecithin powders are commonly used as supplements to support liver function, including detoxification, and to improve fat digestion and absorption in the digestive tract.
The human body naturally produces lecithin primarily in the liver, bile fluid, and brain.

Liposomes can protect the encapsulated nutrients from degradation in the digestive system, allowing more of the active ingredient to reach the bloodstream. This can potentially result in higher bioavailability compared to traditional supplements.
Liposomes can facilitate the delivery of nutrients directly to cells and tissues, potentially improving the efficacy of the supplement.
By protecting the active ingredients from the harsh environment of the stomach, liposomal supplements may reduce gastrointestinal irritation and improve tolerance.
The lipid bilayer of liposomes can protect the encapsulated ingredients from oxidation and other forms of degradation, potentially extending the shelf life of the supplement.
Liposomal supplements are often more expensive than traditional supplements due to the complex manufacturing process. However, the potential benefits might justify the higher cost.
