01The molecule

Beta‑1,3‑D glucan

A molecule critical for immune system function. A long helical backbone with delicate side-branches — and the branching pattern is precisely what makes it work.

02The problem

It was too expensive to matter

Beta glucan had always shown promise. Its high production costs rendered it inaccessible to the average consumer — promising science nobody could afford.

031995–96

A new way to make it

A manufacturing method to synthesise highly pure beta glucan at a cost ordinary people could reach. The science stopped being theoretical.

“The only relevant immune modulator”

Journal of the American Nutraceutical Association. Everything below is what A.J. Lanigan has published about why.

Fact 01

Your immune system is the first line of defense

The body’s primary defense mechanism against disease. It identifies and combats pathogens — bacteria, viruses, fungi and parasites.

Fact 02

It remembers

One of its most remarkable features is the ability to remember pathogens it has encountered before. That memory is the basis of how vaccines work.

Fact 03

About 70% of it lives in your gut

The gut microbiome — trillions of bacteria — plays a crucial role in educating and regulating the immune system.

Fact 04

Sleep is when it builds its weapons

During sleep the body produces cytokines — proteins that help fight infection and inflammation. Chronic stress does the opposite, and suppresses it.

Fact 05

The molecule comes from a common yeast

Beta‑1,3‑D glucan is drawn from the cell wall of baker’s yeast — one of the most ordinary organisms on earth.

Fact 06

Purity is the whole argument

Not all beta glucan is the same. What separates one preparation from another is how pure it is — and how much of it survives to do anything at all.

Fact 07

Two systems, not one

Innate immunity is the first line of defense and responds quickly to invaders. Adaptive immunity develops against specific pathogens and provides lasting protection.

Fact 08

“If there is ever going to be a cure for cancer, the immune system will be at the centre of the technology.”

Knowledge of how the immune system works has already opened immunotherapies for cancer and autoimmune disease.
