Helpful in boosting the immune system
12-09-2021 09:25:27
I was suffering from a terrible virus and bacterial infection i just couldn't shake. After being on antibiotics and feeling so run down i started taking this to try and give me a boost. It does seem to have aided in my recovery. Might be beneficial to take in times of stress to help alleviate pressure on the immune system. I would use again.

Absolutely brilliant product for those with immune systems that need a boost. My hubby went thru Chemo and Radiotherapy 4 years ago and his immune system is shot. He has been taking these every winter, normally has flu for about 3 or 4 weeks, this year its been 3 days. Highly recommend this product.

I have not caught as many colds since taking this and have hardly ever had to have antibiotics. I previously had frequent sinus infections that meant antibiotics and prednisone

More energy

I don't take these everyday, I use them when I am feeling a bit run down. I have only ever taken one in the morning on an empty stomach, they seem to help recovery and I really do feel more energetic. I would recommend them.

My third order for these supplements - I believe they have both prevented me catching some bugs circulating around my workplace/home and have shortened my recovery time when I have caught something. I also feel my general health and energy levels improve when I take these. I take them in the morning on an empty stomach. If I take them at night I find it hard to fall asleep.

Great Product
14-08-2019 19:30:12
I have been taking this product since autumn with a view to overcoming a winter normally characterised by 2-3 bouts of flu or cold. Without changing any other behaviours I have to date been flu/cold free. My view is that this product has worked well for me.

Great product

I gave this to my husband and adult children recovering from the flu and they all felt more energetic. I would recommend this product to anyone who is run down, recovering from illness, stressed or feeling worn out by physically demanding sports.The only negative is Healthpost is out of stock. I am keen to try the Hayfever product from the same company as a preventative in October.\n\n

It works

I recently got a flu and I felt like I was heading towards getting a chest infection. I remembered that I still had some Ki in my cupboard and started taking them. To my surprise I started to feel better the next day! I was very surprised to feel the effect so quickly. I highly recommend it!
