Zooki Liposome Vitamin C: Boosts immunity and protects skin. 14 vials pack

Liposomal vitamin C is vitamin C wrapped in a protective layer of lipids (the same kind of fatty molecules your cells are built from), forming tiny spheres called liposomes.

Ordinary vitamin C has to survive the acidic environment of digestion before your body can absorb it, and at higher doses much of it is simply passed through. The liposome shields the vitamin C on that journey, so more of it is taken up and stays in your system for longer.

And this isn't just theory. 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 1,000mg dose, with no reported side effects.

Because the lipid shell is so similar to the body's own cell membranes, it's a format that works with your body rather than against it: a smoother, more efficient way to take vitamin C, without needing the megadoses that can leave standard vitamin C sitting in the gut.

In short: same essential vitamin, delivered in a form proven to get more of it where it's needed.

For our capsules, take two capsules daily with or without food.

For our liquid sachets:

• One sachet a day – perfectly portioned and ready to drink, simply rip, sip and go.
• Store at room temperature – but for the best taste, keep in the fridge.
• Enjoy your way – straight from the sachet, mixed into water, juice, and smoothies or drizzled over yoghurt, fruit, and oats.

Enjoy in the morning or mid-afternoon for lasting, all-day energy.

Both give you 1000mg of vitamin C per serving in our liposomal delivery system. The difference is how you like to take it, and what else you want alongside your vitamin C.

Choose the liquid sachets if...

You want flavour and a little extra. The sachets come in pineapple, citrus orange and acai berry, taken straight from the sachet or mixed into water, smoothies or yoghurt. They include added vitamin E (with vitamin B12 in some flavours), slip easily into a bag or pocket for taking on the go, and they're the format used in our clinical absorption trial.

Choose the capsules if...

You want simple, flavourless and portable. Two small capsules a day deliver the same 1000mg of vitamin C, with no taste and nothing to mix, easy to keep with you and take anywhere.

Same vitamin C, same daily amount, and both easy to take on the move. The sachets are the more enjoyable, nutrient-rich option, while the capsules are the fuss-free, flavourless way to take your daily dose.
