I have multiple chronic illnesses and autoimmune system problem. The effects of Zaccha are not so noticeable till after taking the 10th bottle. More energy, not easily tired. Sleeping wise is in progress, I'm not a sound sleeper.

My immunity has improved. I catch colds much less often, and the bloating and indigestion have reduced.

Energy and stamina improved. I did the Jiuzhai Valley hike without oxygen support. Sleep is consistently good.

After a few months my fatigue improved and I feel more energetic. I've taken it diligently for years.

After 3 weeks I feel more energetic and no longer need my afternoon nap. The skin itching is gone too.
Overall rating: 5 / 5 from 44 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.

I find that my immune system seemed to have improved as I hardly fall sick when there are people around me falling sick. I'm hoping my energy level can also improve with long term use..

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!

T cell is really a very effective supplement in helping out my sister who is a stage 4 lung cancer patient... After taking T cell for about a month, tremendously saw her improvement and she is getting better while staying at Hospice... I would strongly recommend to the public to trust on getting T cell to see real result. Trust me guys. It really worked on my sister... God bless. Thank you 🙏

Hi Summer, my morning stiffness from my RA is much better and I really noticed the difference when I stopped taking for a month, as I was getting my sister to take it twice a day. Hence, we didn't have enough tablets.

I took a one month break after a 3 month dose, can definitely feel the change. More energy, less lethargic and almost zero flu outbreak.

One week into the T cells. I must say it's a great product. I've taken more expensive stuff, but this one works for me. More energy and mental sharpness. Mild eczema seems to subside.

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.

Overall my right side neck pain alot better now. Besides that I hv other illness such as prostate enlargement and back strain L5/S1. So far after taking these capsules I felt more energetic like playing pickleball games and walking also faster.

Experience with the product have been good so far. Subtle and lasting energy boosts throughout the day and sleep improvement. Would like to suggest if possible to shrink the size of the pill a little more.

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!

Hi, I have been taking T-Cell Activator for about 2 weeks and find that I have better sleep and more energy.

I’ve been using Zaccha’s T-cell activator for a while and found that it helps to alleviate my acid reflux problem. So, I’ve been ordering more of the supplement in the hope that it will completely do away with my needs for gastric medication. The business support is excellent and prompt. Ms Summer, who’s the co-founder, is also warm and passionate with her advice. I am looking forward to even better results from the regular usage.

Have been taking T-CELL for about 3 months now and generally I'm feeling better like waking up energised and aching knees less painful. Attended a Preventive Health Talk given by Dr Jeremy Lim and Co-founder Summer Song to understand better about T-Cell which is informative and beneficial. I believe it's not a magic pill but I'm willing to give a try as our immune system is the core to our health.

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。

Wake up every morning consistently early and felt refreshed since taking T-Cell Activator. Go to bed early unlike before taking the activator, thence to sleep late previously.

I started taking 2 tablets each day for three weeks. I am more energetic and don't need an afternoon nap after taking. I noticed my constant itchiness gone (I am prediabetic). I bought your package for 180 days but am sharing with my brother who has recently gone for radiation due to prostate cancer. He also felt more energized and his recent medical report reveals that he is healing well.

My HK friend that I gave ur supps to after her cervical cancer surgery just told me that she started taking in end Jun and noticed her hot flash gone. Then last month she went Italy with her family and clocked like 11,000 steps a day and didn't feel tired while her kids actually got more tired than her.

I just finished a bottle. Yes, my energy levels are like back to normal without feeling tired after a lunch break. And lasted for a full day. Now onto the 2nd bottle, and will keep monitoring myself. Thanks, Lionel Teo

The T-cell activator is working out pretty well for me. Energy level is also improved and so is my stamina. I am now in Sichuan and just did the hiking trip. I managed it pretty well without the need for oxygen supplement which I saw many people needed. Sleep quality is consistently good and the mandatory afternoon naps are no longer a necessity. Glad I decided to try out the product. Will be reordering when I return from my trip next week.

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.

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.

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.
