What Methylated B Complex Ultra supports

Science-backed, high-impact ingredients.

Why I started Prime Vitality

Why I started Prime Vitality

Built from lived experience. Backed by better ingredients.

It started with a simple question: why do so many supplements promise the world but leave you feeling exactly the same?

After years of trying generic B-complex products and not feeling a difference, I set out to build a formula using the active, methylated forms of B vitamins your body can actually use.

Every batch is made in Britain to high quality standards, vegan, non-GMO, and designed for real life: one tablet, once a day.

The science behind the formula

It comes down to the form.

Many people feel nothing from a B-complex, and the reason is the form: cheap, inactive vitamins your body has to convert first.

0%

of people carry a common MTHFR gene variant

People who carry the MTHFR gene variant turn folic acid into active folate less efficiently. Prime Vitality skips that step by using methylfolate directly, the active form your body can use straight away, so it works for them too.
