Vitamin B12, Liposomal

Liposomal vitamin B12 is vitamin B12 wrapped in a protective layer of lipids (the same kind of fatty molecules your cells are built from), forming tiny spheres called liposomes.

Vitamin B12 is an essential vitamin your body can't make on its own, so it has to come from diet or supplementation, and it isn't always easy to absorb. B12 relies on a multi-step uptake process in the gut, and a good deal of an ordinary oral dose is never taken up. The liposome is designed to shield the B12 as it travels through the digestive system, so more of it can be absorbed 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 B12.

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 a high-strength 2,500µg dose of B12, in an active, vegan methylcobalamin form.

In short: the same essential vitamin, delivered in a form built to make the most of every dose.

Vitamin B12 does a lot of quiet, essential work in the body. Here's what it contributes to, with an active methylcobalamin form and liposomal delivery for enhanced absorption.

Energy

Vitamin B12 contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue.

Mind and nervous system

Vitamin B12 contributes to normal psychological function and to the normal functioning of the nervous system.

Immunity

Vitamin B12 contributes to the normal function of the immune system.

Add to that a high-strength 2,500µg dose per sachet in our liposomal delivery system, and a great-tasting strawberry format you'll actually look forward to taking.
