- Serious immune system and energy production support. -

Zen Therapeutics Ki Immune Defence and Energy Formula is formulated to enhance the immune system and at the same time boost the body’s energy reserves. The plant extracts help increase the number of white blood cells and enhance the activity of the body’s natural killer cells to help promote a healthy immune system.

Astragalus is a major herb prescribed in China for strengthening the immune system and also has the added benefit of being a potent energy tonic and powerful antioxidant.

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.

Update on my review dated 22/4/14 ....
A year now since I started using this product and still no cold/flu. I take 1 capsule daily just before breakfast.
Still believe taking this is the reason I have not become sick.

This has to be my favourite immune booster, and I really notice the change in my energy levels, since taking it. Its a great combination of herbs.

  • star

My health support person put me on Ki a couple of months ago and the effects for me was instant ---- my energy levels lifted noticeably and my brain functions became more astute. When taking it I do not need an afternoon nap and I just feel so much better in myself. I am recovering from a car crash which left me with fatigue, brain and body issues. I reckon this product is speeding up the quality of my life (naturally) as it's a herbal medicine. Thanks KI.

While on holiday in Canada I had the flu. I found a good product from a natural health shop. Back in NZ I could not find it so tried this product which is similar. I work long hours and get run down/sick frequently but have had none of my usual colds/sniffles in the past 4 months. Since that is unusual I believe it is because of these tablets.

Feel like I am coping with winter since I have been taking this supplement! Energy levels are more even throuout the day, and so far no illness even though those around me are getting sick. Intending to continue taking this supplement as i feel more 'balanced'.

  • star

I work in a very large open plan office and have been taking this product for 2 years. Everyone around me has had colds and flu during this period and I have managed not to catch anything. Prior to taking this product, I had several colds and was generally run down over the winter period. I put my resistance to colds and flu down to regularly taking this product. I highly recommend this product.
