Vitamin D3+K2, Liposomal

Each liquid sachet or 2 capsule serving contains 75μg (3000IU) Vitamin D3 + 100μg Vitamin K2.

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.

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 3000 IU of vitamin D3 plus vitamin K2 per serving in our liposomal delivery system. The difference is how you like to take it, and what else you want alongside your vitamin D.

Choose the liquid sachets if...

You want flavour and a little extra. The mixed berry sachets can be taken straight from the sachet, mixed into water, juice or smoothies, or drizzled over yoghurt and fruit. They include added vitamin E and B12, and slip easily into a bag or pocket for taking on the go.

Choose the capsules if...

You want simple and flavourless. Two small capsules a day deliver the same 3000 IU of vitamin D3 and vitamin K2, with no taste and nothing to mix, easy to keep with you and take anywhere.

Same vitamin D, 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.
