28 years,
one formula.

One formula, built by a biochemist in Cambridgeshire in 1998 and never changed since. The athlete who has taken it every morning since 1998 ended up buying the company that makes it.

1998

A biochemist and a breakthrough

Biochemist Brian Welsby had spent years on a question most supplement makers skip: the form each nutrient takes, not just the list of names. His answer was Food State nutrition, with minerals cultured in yeast and vitamins complexed the way they occur in food, rather than isolated synthetics pressed into a tablet.

In 1998 he built a complete daily formula around that idea, 34 vitamins, minerals and plant nutrients in one scoop, and called it Breakthrough. The same year, Paula Radcliffe, then a track and cross-country international, started taking it. She never stopped.

2003

The world record.

London Marathon, April 2003. Paula runs 2:15:25, a world record that stands for sixteen years. Behind it are 130-mile training weeks, and elite marathon training is exactly where nutrition gaps show first.

Through that record, three London wins and three New York wins, her morning routine didn’t change: one scoop of the same formula. Sir Ranulph Fiennes carried the original Breakthrough formula on polar expeditions in the same era. He is not a current endorser of Immufix.

The philosophy

Why it has never changed.

Nutrients the way food carries them

Food State minerals are cultured in yeast and vitamins are complexed the way they occur in food. It’s the principle the formula was built on in 1998.

Everything declared, nothing hidden

Nothing hidden behind a blend name. All 34 nutrients are listed with their exact per-serving amounts, and every claim on this site uses only wording authorised in the UK.

One formula, tested by time

Twenty-eight years of daily use by elite athletes and everyday customers. It has not been reformulated once since 1998.

The formula Paula Radcliffe took through every marathon of her career is the same one in every pouch today.

2026

The customer buys the company

After twenty-eight years of daily use, Paula and a group of friends buy the company. Among them is Phillippa Spilsbury, who found the formula as a customer and now co-owns Be Well Health & Nutrition, the company behind it.

It’s a rare structure in this industry: the people who own the formula are the people who have taken it longest. Their first decision as owners was the simplest one, to change nothing about what goes in the pouch.

Today

Breakthrough becomes Immufix

Same formula, new name, still made in Cambridgeshire. 34 nutrients in one daily 25g scoop, exactly declared, in orange and vanilla. Vitamin C, vitamin D, zinc and selenium contribute to the normal function of the immune system.

The full label, with every amount and what each nutrient contributes to, lives on The Science page. Every declared amount is listed there.
