So impressed with the results, I had terrible fatigue after a cold, shallow breathing and general weakness. Being a Mum of 3 & a fitness instructor, I’m very busy and was starting to feel like I couldn’t cope. After 3 days I feel like I’ve got my energy back, more relaxed, less stressed and breathing better. Highly recommend!

Very helpful product that works but the previous product that was used was the Thyroid Tonic which was more specific for the condition and better overall but the the Adrenal Tonic still has similar ingredients so still helpful though not as good. It is a real shame the Thyroid Tonic was discontinued!

Excellent product

Normally I do not write review, and not normally give “full mark” for the product. However, this product such like life saver. From the beginning, I tried the small bottle and wow, after couple of days I had found myself less irritated and more peaceful, and the biggest change is that I can get more sleep not only 4 hours or 5 hours. Now, I can wake up with fresh myself and feel more rejuvenated. I also found it is from New Zealand as well:) Thank you healthpost to stock this product. :)

Definately helped with my sleeping, I took 2 big bottles so far. The taste is nice too. It is very expensive however sadly.

Thought I'd try this out because many years ago I used to run on adrenaline and over the years have learnt to tone things back a bit. After 5 days I found I have more sustainable energy. I think I'll do a course of this (500ml x 1) 3 times this year and see where I'm at then.

My daughter has had glandular fever and was suffering fatigue for months afterward which was seriously affecting her schooling. Taking adrenal tonic has been a huge boost for her. She has managed 5 days a week at school instead of the 1 to 2 days a week without it. Highly recommended.

It has helped lift my energy levels

Yes, I feel that this has helped increase my energy levels. After suffering from Pneumonia last year I have found it a struggle to feel energised again but I feel the tonic is helping to lift my energy levels and I also feel that I am helping my body to heal by supporting it with the tonic.
