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.

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!

We have been trialing these tablets for the last two months, they are quite strong/ work very well.. Beware if you have Gastra reflux and take them in the morning with food as they will keep you awake..

I was recommended to take astragalus and olive leaf extract due to chronic illness to support my immune system (chronic fatigue syndrome and fibromyalgia). I found my stomach couldn't tolerate these supplements separately so I thought i'd give this a go after seeing they had these things as the active ingredients. I'm so glad I did because these are amazing and don't trigger my IBS at all. I tend to only take them when I have a cold and my immune system needs an extra helping hand, but my cold symptoms are significantly reduced when I take them and it will only last a few days compared to a few weeks without them (this prevents me have a significant crash and being completely bedridden with the chronic fatigue syndrome). I gave these to my family when they had a cold as well and they were almost completely symptom free later in the day. I see they have recommended these for chronic fatigue syndrome under the overview, but from my experience these don't boost my energy or relieve my fatigue (I haven't found any supplement that does). But like I said they do prevent me from having a major crash when I'm sick, which makes them well worth it!
