Providing a better way
for our customers...
Researcher, Manufacturer & Distributor
Our story
"We have hundreds of thousands of happy customers in more than 40 countries whose health spans have been improved by using our products… I am one of them.
I really get a kick out of the fact that we've got customers who have been with us for 20 years even though they are scattered all over the world. There is a lot of misinformation circulating about health and supplements. Most people are so busy that they don't have time to do in-depth research. This is why we do the research to ensure that our formulas get the results that you are looking for, and they really make a difference to the way you look and feel."

Our manufacturing facility
Our formulas are complex, and our ingredient specifications are much more exacting than 'normal' supplements. We comb the world from the Tibetan Plateau to the Amazon rainforest to find the most effective ingredients for the formulas objectives. This would not be possible if we were to produce our products like most other brands… with a contract manufacturer.
We control every step of the process. This is why in 2012, we built a new state-of-the-art pharmaceutical-grade facility in New Zealand to house all departments to ensure there are no compromises in any stage of the process. This replaced the three buildings we had used in the preceding years.
At the bottom of this page, there are videos about our facility and how the supplements are made.







Our people
Over the last 20 years, we have built a solid team of key people in the business, not only in our headquarters in New Zealand but globally. Like our customers in over 40 countries who are the most important part of our business, the people who make up our staff and advisors are also key to the success of Xtend-Life.
Equally important is that Xtend-Life remains a family-owned business and can operate in the best interests of customers and staff without the pressures of external financial interests.

Our customers
Our customers tend to be in the older age bracket, knowledgeable about the benefits of professional supplementation and have a desire to increase their health span so they can enjoy their later years active and without the normal age-related conditions.
In the last 20 years, we have serviced more than 350,000 customers in 40 countries, with thousands of customers still receiving their monthly packages 20 years later.
