"Norton Shopping Guarantee provides a sense of trust to the new products before customers are even able to write product reviews, and that helps us.”

For more than 35 years, Life Extension has supplied consumers with a large selection of high-quality vitamins and supplements in pursuit of human health and longevity. Motivated by a passion for knowledge and scientific advancement, research and development have been the driving forces of their unique formulas. An in-house science team creates the specialized formulas which allows Life Extension to produce their own supplements with the highest quality ingredients.

Gus Milla, eCommerce Manager of Life Extension, explains that “People who are serious about their health can see the quality of the products from the beginning. That, in combination with specialized supplements that aren’t easy to find, is what keeps our customers loyal to Life Extension.”

Though people generally know that diet and exercise play key roles in living a healthy life, getting the right type and amount of nutrients is not always easy. Life Extension is able to assist in building an effective and individualized supplement plan through the use of blood tests. They also publish their own magazine so customers can stay up to date with the latest medical research and findings, therapies, and treatments.

So why did this highly reputable and successful company decide to try Norton Shopping Guarantee? “We wanted to build on the trust our visitors have with our site and brand to ensure they felt complete confidence in buying from us regarding the purchasing process and the security of their information,” replied Gus. “We work to make our customers’ purchase decisions easier. This type of guarantee benefits our customer base and was the driver for implementing this solution.”
