How it works

Beyond a basic multivitamin

01

The essentials, done properly

A full spectrum of vitamins and chelated minerals at meaningful doses, in forms your body can actually absorb.

02

Active, bioavailable forms

Methylfolate, methylcobalamin and P5P are the ready-to-use forms of folate, B12 and B6, with no conversion required.

03

A specialist layer

Nicotinamide riboside, ubiquinol CoQ10, spermidine and broccoli seed extract add cellular-health nutrients a standard multivitamin leaves out.

Built for the life you lead.

Quantum is a complete daily foundation of comprehensive vitamins, chelated minerals and longevity compounds, whoever you are and whatever you ask of your body.

Students

Long terms and late nights ask a lot of you at once. A full spectrum of B vitamins, vitamin C and vitamin D that contribute to normal psychological function, the reduction of tiredness and fatigue, and the normal function of the immune system.

Why the forms matter

Not all multivitamins are equal

Active B-vitamins

Methylcobalamin, methylfolate and P5P are pre-converted, so they work even if your body is less efficient at activating the cheaper synthetic forms.

Chelated minerals

Magnesium, zinc and selenium are bound to amino acids such as bisglycinate and selenomethionine, for gentler digestion and better absorption.

Cellular-health nutrients

Ubiquinol CoQ10, nicotinamide riboside and spermidine support energy production and healthy cellular ageing.
