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 fibers 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.

Overall rating: 5.0 / 5 from 10 reviews.

I am a former AMI patient but that was 20 years ago. I replace my stents in August of 2025.....i am having a heart profusion test at NHC tomorrow 5th August Wednesday due to a strain at my pectoral muscles area. The heart perfusion test is a precautionary measure. The t cell capsules are helpful but I guess it takes time.

There were also a couple of times where I thought I was feeling as if I might be coming down with a cold or cough, but did not actually come down with it and was okay the next day.

T-CELL ACTIVATOR™ WELCOME KIT 60 DAY SUPPLY

I was quite skeptical at first about trying a supplement that’s new on the market and one I only came across on social media. Before deciding, I took the time to visit the Zaccha website and read up about it in detail. To my surprise, I started feeling the difference within just two days! I felt more energetic, mentally sharper, and had smoother, faster bowel movements. What impressed me most was the noticeable improvement in my sleep quality — I wake up feeling truly rested and refreshed. I’m genuinely excited to see even more positive changes as I continue with my second bottle!

I feel more energized and lesser brain fog. The reason why I'm taking is also to see if it helps in my pituitary tumor after surgery. As not all the tumor is removed due to its proximity to a main artery.

GPComplex mechanism
How GPComplex® works

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.
Backed by human trials
