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.

Hi Summer, I’ve been feeling weak every morning when I wakeup for months because of my low sodium in my body. However since I started taking two T-cell capsules every morning the first thing when I wake up for about 2 weeks now, I feel like my energy is better. I do not feel lethargic or weak, which to me is a win!

去年我的母亲9月份开了一个直肠癌的手术。是二期的,手术还是比较成功的。之后做了一个化疗,但是整个化疗过程中她比较痛苦。其实也没有坚持下去。也是医生看到她的整个状态和手术之前有很大的差别 让她叫停了。那么我当时就抱着一个试一试的心态 然后就跟那个T-cell Activator联系。那么妈妈服用了两个月以后 她的食欲很快地就恢复了,然后她有了食欲的话就有了信心了,精神气也很快地恢复。 的确就是在下一次的体检的时候,再去见医生的时候,不管她自个儿她都感觉到这个状态很好,连医生都觉得很诧异。他说妈妈一下子感觉到她恢复了她手术前的那个精神状态,他觉得非常的吃惊。妈妈到现在也还是坚持这个药。然后去年九月份的手术,今年四月份 妈妈就跟我两个人到日本去旅游,然后有的时候徒步一万步她都能够很精神十足地完成了这个所有的旅途。而且她整个过程当中,她还不忘了带上这个按时服一早一晚的。然后我也后来把这个药介绍给了一些其他的朋友,也是中老年患者,或者是他的母亲刚手术 过了以后。他们都会主动地跟我说 哎呀我还想再买,可见他的这个反应还是都比较积极的。我认为这个药比较好的一点就是,我不把它当药看,我更多把它当保健品看。它真的是全天然的,它对于患者本身服的药,没有太大的冲突,它也能够很好的提神 这个患者的这种一些食欲,或者是她一些基础病的问题 所以呢 我是觉得是不错的一个选择。

Hi Summer. I brought my mum out today and she suddenly asked me if she can increase the dosage. She mentioned she seems to be more energetic and can walk longer after taking.

T-CELL ACTIVATOR™ QUARTERLY SUBSCRIPTION

I started on 09AUG and have been taking 2 capsules each in the morning and before bed. I do feel more energetic and sleep better but not markedly. My appetite improved by heaps. My CEA was high during my last checkup on 08Aug. Next checkup is 28Oct. I hope I can see a significant lowering of the CEA by then.

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.
