The absorption problem no one talks about
Walk into any pharmacy and you will find shelves lined with supplements. What the label does not tell you is how much of that dose actually reaches your bloodstream. For most standard supplements, the answer is surprisingly little. Gastric acid, bile salts, intestinal wall resistance, and liver metabolism combine to destroy or block a significant portion of any orally taken nutrient.
What is a liposome, exactly?
A liposome is a microscopic spherical vesicle made of one or more phospholipid bilayers — the same molecules that form the membranes of every cell in your body. Inside the sphere, water-soluble nutrients are protected from the external environment. Fat-soluble nutrients can be embedded within the phospholipid membrane itself.
A liposome is, in essence, a miniature replica of a cell.
Because liposomes are made from the same material as cell membranes, the body does not recognise them as foreign. They are treated as cellular structures — not as foreign objects to be broken down.
How liposomal delivery works step by step
Encapsulation
Water-soluble nutrients (like vitamin C and glutathione) are dissolved in the aqueous core. Fat-soluble nutrients (like CoQ10 and vitamin K2) are embedded in the phospholipid bilayer.
Gastric acid protection
The phospholipid shell acts as a protective barrier against gastric acid. Liposomes pass through the stomach largely intact — the nutrient inside is shielded from degradation.
Intestinal absorption
In the small intestine, liposomes are absorbed via endocytosis — the same mechanism cells use to engulf cellular components. The liposome is absorbed as a whole unit into intestinal cells, bypassing normal piecemeal nutrient absorption.
Cellular delivery
Once inside intestinal cells, the liposome releases its contents directly. From there, the nutrient enters the lymphatic system and bloodstream, bypassing much of the first-pass liver metabolism.
Liposomal vs. standard: what the numbers show
What real liposomes look like — and how to spot fakes
Molecularly formed phospholipid vesicles, verified by TEM analysis showing double-layered structures.
A nutrient simply mixed with lecithin powder. No encapsulation, no liposomal structure, no meaningful improvement in bioavailability.
The PPH standard: Advanced Dry Liposomal Technology
Our Advanced Dry Liposomal Technology preserves molecularly formed liposomal structures in a dry powder matrix within a plant-based capsule. This solves both the absorption problem and the oxidation problem of liquid liposomal products.

Conclusion and next step
Liposomal technology is not a marketing trend — it is a scientifically validated approach to solving a fundamental problem in oral supplementation. Explore the full PPH range and read our independent lab reports.
