What are liposomal vitamins and how do they work?

The absorption problem that is rarely talked about

In every drugstore, the shelves are stocked with supplements. What the label doesn't tell you is how much of the dose actually makes it into your bloodstream. Stomach acid, bile salts, the intestinal wall, and liver metabolism all work together to ensure that a portion of any ingested nutrient is broken down or not absorbed.

What exactly is a liposome?

A liposome is a microscopic sphere made up of one or more double layers of phospholipids: the same molecules that make up the membranes of all your cells. Inside the sphere, water-soluble nutrients are shielded from their surroundings. Fat-soluble nutrients can be incorporated into the membrane itself.

A liposome is essentially a miniature version of a cell membrane.

Because liposomes are made of the same material as cell membranes, they align well with how the body handles fats and membranes.

How liposomal delivery works, step by step

1

Encapsulation

Water-soluble nutrients (such as vitamin C and glutathione) are dissolved in the aqueous core. Fat-soluble nutrients (such as coenzyme Q10 and vitamin K2) are incorporated into the double layer of phospholipids.

2

Protection against stomach acid

The phospholipid shell is intended as a protective layer against stomach acid, so that the nutrient inside is less broken down during digestion.

3

Absorption in the intestine

In the small intestine, liposomes can be absorbed via endocytosis: the mechanism by which cells "enclose" particles. This is a different route than the normal absorption of individual nutrients.

4

Release

After absorption, the liposome releases its contents. The nutrient then enters the lymph and the bloodstream.

Regular vs. liposomal: the differences

NutrientChallenge with the regular formLiposomal approach
Vitamin CAbsorption decreases with higher doses per intake1.76× higher bioavailability measured (CT-0007-17)
GlutathioneLargely broken down in the stomach and intestinesEncapsulated for protection during digestion
Coenzyme Q10Large, fat-soluble molecule that is relatively poorly absorbedIncorporated into a phospholipid structure
IronCan cause gastrointestinal issuesEncapsulated; research into tolerability is in development

What real liposomes look like, and how to recognize fakes

Real liposomes

Phospholipid vesicles formed under controlled conditions. The double layers can be made visible using transmission electron microscopy (TEM).

Powders with a lecithin coating

A nutrient that has simply been mixed with lecithin powder. No encapsulation and no liposomal structure.

The PPH standard: dry liposomal technology

Our dry liposomal technology preserves liposomal structures in a dry powder matrix, inside a plant-based capsule. This is how we combine liposomal encapsulation with a stable form without preservatives.

Stable — the dry form is less sensitive to oxidation than a liquid
No preservatives — stable without chemical additives
36-month shelf life
Certified production — FSSC 22000, independently audited by Kiwa Nederland B.V.

For which nutrients is liposomal delivery interesting?

GlutathioneLargely broken down in the stomach and intestines in regular form
Vitamin CAbsorption decreases with higher doses per intake
Coenzyme Q10Relatively poorly absorbed from regular capsules
IronRegular iron salts can irritate the intestinal mucosa
NAD+Rapidly broken down in the gastrointestinal environment
NACStable form of the amino acid cysteine

Conclusion

Liposomal technology is not a marketing trend, but an approach that has long been researched to improve the oral absorption of nutrients. View the PPH range and read more about our research.

Frequently Asked Questions

Lecithin, the source of the phospholipids in liposomes, is a natural nutrient. Nevertheless, discuss every supplement with your midwife or gynecologist before taking it during pregnancy. Some ingredients, such as ashwagandha and berberine, are not recommended during pregnancy.
High doses of regular vitamin C can cause loose stools because unabsorbed vitamin C attracts water in the intestine. For every supplement, stick to the recommended daily dose on the packaging.
Ask the manufacturer how the liposomes are made and if measurements have been taken, such as TEM images, particle size (real liposomes are between 50 and 200 nm), and the polydispersity index (PDI; below 0.3 indicates a uniform preparation).
