For many people, chronic conditions are seen as part of aging, thinking that nothing can be done to improve their condition.

They resign themselves to a lifetime of medication — hoping to keep symptoms under control, even if it means living with side effects.

 

You may feel it every day as fatigue, a lingering cough, skin issues, poor sleep, loss of appetite, getting sick more often, and taking longer time to recover.

What many people don’t realise is that these chronic conditions often share the same root cause: Immune dysfunction and chronic inflammation.

Understanding this connection is key to addressing the problem at its source.

So why do our immune system weaken as we age?

Meet T cells — the missing link in immune health

T-cells are your body’s elite defense team — detecting and eliminating viruses, bacteria, and cancerous cells with precision. They also regulate your immune system, calming inflammation once the threat is gone to protect healthy tissues.

Immune aging begin as early as 40.

As we age, T-cell production and function decline, while chronic inflammation quietly rises. This imbalance is linked to increased risk of infections, cancer, and age-related diseases.

Meet T-cells: a type of white blood cell that plays a critical role in our immune system.

They find and destroy viruses, bacteria, and even cancer cells, protecting our body from diseases.

After the age of 40, our body’s T-cell production declines significantly due to thymic involution—the gradual shrinking of the thymus.

By age 50, T-cell output drops by about 75% compared to when we were 20.

And by age 70, this decline can reach a staggering 95%.

That means your body gradually loses its ability to fight back, as chronic inflammation silently causes ongoing damage. You may be thinking: “But I’m already on medication. Isn’t that supposed to make me better?” The truth is, while medication manages symptoms, it doesn’t rebuild your immune defense.

But Here's the Good News

While ageing is inevitable, your rate of decline is NOT. Now, there’s a scientific way to activate existing T-cells in your body to help your immune system thrive again. 

A method so effective it is clinically proven to suppress tumor growth (anti-cancer) and improve immune function in patients with chronic bronchitis.

Undergone Phase 3 Clinical trial & Real World Efficacy

There are countless immune health supplements out there.

But less than 0.1% have been backed by Phase III clinical trials — the gold standard in clinical research.

That means this ingredient has been scientifically proven to be safe and effective in large groups of real people.

It’s what makes this product far more trustworthy and reliable than most over-the-counter options.

How is T-Cell Activator™ Different From
Other Immune-boosting Supplements or Herbs?

Join Thousands Who Have Benefitted From T-Cell Activator™

Goodbye immune ”boosters”.
Hello balanced, resilient immune system

T-Cell Activator™ is ideal for adults who:

  • Want to maintain long-term health, promote vitality, resilience and healthy longevity
  • Want advanced immune support due to their chronic conditions like diabetes, COPD, osteoarthritis, hypertension to maintain vitality
  • Are recovering from cancer or a major illness and looking to use supplementation to help you improve physical condition and energy level in the recovery process

T-Cell Activator™ contains GPComplex®, a patented bioactive polysaccharide extracted from glycyrrhiza uralensis (commonly known as Chinese licorice root). It has been clinically proven to enhance T-cell activity and modulate response — helping your body defend against viruses, inflammation, and cancer cells. By restoring immune balance, it helps your body fight back, heal faster, and recover stronger.

GPComplex® activates T-cells and modulates immune responses through two pathways.

  1. Direct Interaction in the Gut: Some polysaccharides are partially absorbed or interact with immune cells in the gut-associated lymphoid tissue (GALT). Specialized antigen-presenting cells, such as dendritic cells and macrophages in Peyer’s patches and the lamina propria, recognize polysaccharides via TLRs (especially TLR). This triggers intracellular signaling cascades that enhance cytokine production, activate T-cells, and modulate the immune response.
  2. Microbiome-Mediated Interaction: Many bioactive polysaccharides act as prebiotics, feeding beneficial gut bacteria like Bifidobacteria and Lactobacilli. These microbes ferment the polysaccharides into short-chain fatty acids (SCFAs) and other metabolites, which can indirectly modulate immune responses. SCFAs influence TLR expression and signaling, helping maintain immune balance and reducing excessive inflammation

T-Cell Activator™ is made from 100% natural, plant-based polysaccharides. It has had no reported side effects in over 25 years of use.

It contains no synthetic chemicals or artificial additives — and is safe to take alongside other supplements or medications. If you have a known allergy to licorice or polysaccharides, consult your doctor before use.

T-cell activation and proliferation occur in several phases typically taking days to weeks. Immune modulation takes place typically 4 – 6 months. Our clinical studies have shown T-cell proliferation and immune modulation over the course of two months. Most people start noticing improvements in around 2 – 8 weeks — such as better energy, appetite, digestion and sleep. People with long standing health problems may take up to 6-8 months to feel an improvement. Effects vary according to your immune function, daily habits, and existing health conditions.

Yes. T-Cell Activator™ is a non-invasive, natural immune modulator and does not interfere with medication. There are no reported interactions between T-Cell Activator™ and medications. However, it is best to consult your health care provider if you have specific medical concerns.

 

Absolutely. T-Cell Activator™ is designed for long-term immune support and health maintenance.

For adults above 60s, who want to keep their immunity and body strong even as they age. We recommended taking it consistently, and on a daily basis for immune resilience, energy, and healthy aging.

Generally healthy or younger individuals who feel their immune system is out of balance, due to lifestyle or environmental factors, may choose to take it until they notice improvement.

Take 2 capsules daily for general immune support.

For those looking for additional support or are managing chronic health conditions, you may take 4 capsules daily (2 in the morning, 2 in the evening).

It is best taken on an empty stomach — consistency is more important than timing.

Unlike generic supplements or TCM herbs or supplements, the active ingredient in T-Cell Activator™ has undergone the most rigorous large-scale Phase III clinical trial proving its safety and its benefits in immune modulation, anti-inflammation, anti-infection, anti-cancer effect. 

To put this in context, out of all the supplements on the market, less than 10% have ever been tested in human studies. And when it comes to the most rigorous standard — Phase III human clinical trials — the number drops to less than 0.01%. 

Our extraction method has received multiple international patents, including a recent one in Singapore for enhancing T-cell proliferation. It is also patent-pending for the treatment of cancer-related fatigue.

This is where we truly stand out — not just with strong customer testimonials, but with real scientific innovation and validation at the highest level.
