Meet T-cells, the missing link

Your immunity starts aging at 40

As you age, T-cell production and function decline while chronic inflammation quietly rises. This imbalance is linked to more infections and age-related conditions, and it begins decades before you feel it.

  • 01
    T-cells detect and clear threats. Your body's elite defence team.
  • 02
    They also calm inflammation. Balance is the key to healthy ageing.
  • 03
    That balance fades with age. T‑cell Activator® helps restore it.

How GPComplex® works

A patented extract that works where your immunity lives

About 70% of your immune cells reside in the gut. GPComplex® acts there, through two pathways.

74% IN THE GUT (GALT)
of immune cells live in the gut-associated lymphoid tissue.
GPComplex® bioactive polysaccharide
Directly

Activates receptors on immune cells in the GALT, triggering T-cell activation.

Indirectly

Acts like a prebiotic, feeding good gut microbes to strengthen the gut barrier and support immune balance.

Clinically proven

The numbers behind the claim

In a Phase II randomised, double-blind, placebo-controlled, multi-centre trial of 240 participants, GPComplex® significantly improved T-cell measures.
