High strength Vitamin D3 with added K2 for superior absorption; providing daily support for your immune system, muscles & bones.
Liposomal vitamin D3+K2 is vitamin D3 and K2 wrapped in a protective layer of lipids (the same kind of fatty molecules your cells are built from), forming tiny spheres called liposomes.
Vitamin D3 and K2 are both fat-soluble, which means your body absorbs them best in the presence of fats. Taken as a dry tablet with nothing to carry them, a good deal can go to waste. The liposome surrounds them in a lipid layer designed to shield them as they travel through the digestive system, so more is protected on the journey and taken up rather than passed through.
We've seen how powerful this delivery method can be. In a double-blind, randomised human trial on our own liposomal vitamin C, blood levels reached almost four times higher than standard, non-liposomal vitamin C at the same dose, with no reported side effects. That's the same liposomal technology we use to deliver vitamin D3 and K2.
Because the lipid shell is so similar to the body's own cell membranes, it's a format designed to work with your body rather than against it: a smoother, more efficient way to take two of the most important fat-soluble vitamins, in a form built to make the most of every dose.
In short: the same essential vitamins, delivered in a form built to get more of them where they're needed.

Bone responds to the load it carries, so significant weight loss of any kind is associated with some loss of bone mineral density. Recent studies of people on GLP-1 medicines have reported the same pattern, tracking the amount of weight lost.
Vitamin D supports normal calcium absorption and vitamin K contributes to the maintenance of normal bones, which is why the two are paired.
Supplements are a supporting measure. The best-evidenced way to look after bone during weight loss is weight-bearing and resistance exercise.

Zooki wraps each nutrient in liposomes: tiny spheres made of phospholipids, the same kind of lipid your cell membranes are built from. The liposome shields the nutrient as it passes through the digestive system, so more of it is protected on the journey.
In a double-blind, randomised human trial on Zooki's liposomal vitamin C, blood levels reached almost four times those of standard vitamin C at the same dose. Zooki uses the same liposomal approach across the range.
Zooki is stocked in over 1,400 locations across the UK, including Boots, Holland & Barrett, Selfridges and Harrods, and in more than 50 countries. PPRX supplies the range under the PPRX × Zooki partnership.
