T-cell Activator® is clinically studied to support healthy immune regulation, including T-cell function and a balanced inflammatory response. Formulated in Singapore from a single, rigorously researched active ingredient.
Take one serving first thing in the morning or last thing before bed, whichever fits your routine and is easiest to stick to. Clinical studies were conducted on an empty stomach, though timing matters far less than consistency. The results come from showing up daily.
Our active ingredient is a bioactive polysaccharide extracted from Chinese Licorice Root through a patented process — a natural carbohydrate in the same family as plant fibres and prebiotics.
It works primarily through the gut, which is where much of your immune system lives. It’s safe to take alongside other supplements or medications.
The immune system is complex, and everyone’s starting point is different. When you feel a shift, and how noticeable it is, depends on your existing baseline and how attuned you are to subtle changes in your body.
Here’s what our 12-week clinical studies and ongoing customer experience suggest:
Weeks 1–2: Adjustment
Your body begins responding to the active ingredient. Some customers experience a brief adjustment period during this phase. This is normal.
Months 1–3: Early Shifts
Many customers begin noticing subtle but meaningful changes: improved digestion, steadier energy, reduced fatigue, and for some, better sleep.
Month 3+: Systemic Change
With consistent daily use, deeper immune support begins to take hold. This is where the compounding effect of the ingredient starts to show.
Month 6–12: Resilience & Vitality
Customers who stay consistent over six months to a year report greater immune resilience and an overall improvement in vitality and quality of life.

A patented extract, two powerful pathways
GPComplex® is a patented extract from Chinese licorice root. Since approximately 70% of immune cells live in the gut - your body's largest immune organ - it works through two pathways:
- →Directly. Activates receptors on immune cells in GALT, triggering T-cell activation.
- →Indirectly. Acts like a prebiotic, feeding good gut microbes to strengthen the gut barrier.
Set apart from 99% of supplements
Phase II randomised, double-blind, placebo-controlled, multi-centre trial, 240 subjects.

One active. Nothing it doesn't need.
