My wife and I have recently moved to Colorado, USA from the United Kingdom to establish a residential training center for athletes of all abilities to train and live at altitude.

Anyone who has been at altitude will know that the decrease in available oxygen creates a major challenge to the body's energy supply systems. I was immediately interested in ACT as it provides vital support and supplementation at a cellular level in a form that is healthy for the body.

I have tried a number of energy drinks over the years, all of which have come with a number of issues for me. I don't drink caffeine so a large hit of caffeine makes me feel "wired" and high sugar contents and various artificial sweeteners and flavorings led to energy peaks and troughs and stomach cramps and often nausea - not a great combination for training!

I was surprised to discover when I had finished that I had run the route 30 seconds faster than I normally do, and had been holding back too. The next run I did was a tougher one over trails that started at 8,500 feet and climb to > 9,000 feet. Again I found I had bags of energy and set another best time for that route too! Since then I have been taking ACT every day, half a packet in the morning and half a packet after lunch. My running is going great - the energy that ACT releases in my body has resulted in me making significant gains in both endurance and speed. I unfortunately turned an ankle heavily on a trail run a few weeks ago so had not been able to run for nearly 2 weeks while the swelling went down! I had entered my first ever trail run at altitude - the ankle injury meant I decided to take it easy and just get round. I finished 7th in my age group which I was very pleased with under the circumstances. Last weekend I raced in a shorter race and finished 3rd in my age group, only 11 seconds behind the age group winner. Again I was very pleased as I am racing against people who have been living and racing at altitude for years, I have just arrived!

ACT gives me the ability to dig that bit deeper when I need to and also recover more quickly after training and racing. A further benefit of ACT is the ratio of sodium to potassium. All energy drinks that I have seen and tried are relatively higher in sodium and lower in potassium. Generally most people have adequate levels of sodium in their diet so there is no requirement to supplement. This is interesting as potassium is the chief intracellular mineral. Potassium concentration in cells is required to achieve a well regulated exchange of nutrients and waste products between the cells and their external fluid environment. It also plays a key role in maintaining electrical gradients across cell membranes that is vital for the transmission of nerve impulses and effective muscle stimulation. ACT therefore provides a key ingredient to enable efficient metabolism and energy delivery at a cellular level.

I am so excited about ACT and talk to anyone who is prepared to listen. Just about everyone can benefit from ACT - the potential market is huge and I am also excited at now being involved in the energy drinks business and helping others to establish another income stream!
