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.

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

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!

Not great
22nd May 2018
I was really hopeful of this product. After reading all the amazing reviews I thought it would help. Unfortunately it hasn't helped me at all. Perhaps this is because I was already sick when I started taking it, however I thought 3 1/2 weeks of taking the tablets might help somewhat. Possibly it has better use as a preventative measure. I won't be buying this product again.

I was recommended this by a friend while in North Queensland on holiday. I was coming down with the flu and recovered to enjoy my holiday within a couple of days. A must for anyone who gets sick.
