Innerbody Research recently celebrated its 20-year anniversary online. Over the past two decades, we have helped tens of millions of readers make more informed decisions involving staying healthy and living healthier lifestyles.

We extensively test each health service we review. We try our best to give you, our readers, an unbiased exploration of at-home health services, free of marketing jargon or gimmicks. We evaluate the service based on our adherence to quality, the latest medical evidence and health standards, and a simple question: would we buy the product or service ourselves if it weren’t part of our job, and would we recommend it to family and friends?

Additionally this review of Xtend-Life, like all health-related content on this website, was thoroughly vetted by one or more members of our Medical Review Board for accuracy.

Right before the turn of the millennium, Xtend-Life was founded in New Zealand by entrepreneur Warren Matthews and bio-scientist Dr. Munem Daoud. Under their initial vision, Xtend-Life products were meant to stave off the symptoms of aging for as long as possible.

Back then, relatively little research had been conducted with regards to age-related cellular damage or the effect of free radicals on the aging process. What Dr Daoud and Matthews did know, however, was that aging can progressively make body systems less adaptable; they start functioning less efficiently, take longer to recover, or even begin to degenerate. This can lead to worsening digestive problems, dwindling hormone production, a weaker immune system, problems creating new muscle mass, or even generalized lack of energy.

Thankfully, however, a big part of this process can be influenced by healthy habits and thorough nutrition. The purpose of Xtend-Life supplements is to provide synergistic blends of ingredients and nutrients that can help stave off the effects of aging for as long as possible, keeping organs and systems functioning like those of a young person.

In 2001, Xtend-Life launched its first version of the Total Balance supplement, meant to delay cellular aging in general. During the following years, Xtend-Life’s product range expanded to address specific systems and symptoms and to include superfood extracts and protein powders for athletes. A few years later, it also added a skincare line, Kanapa, to round off its quest for prolonged youth.

Xtend-Life’s catalogue now includes over 50 different products ranging from multivitamins and herbal extracts to superfood-based shakes and beauty creams. The company organizes these products into three main categories:

1. Dietary supplements

2. Superfood extracts (Zupafood)

3. Skincare line (Kanapa)

All of the products share the original unifying characteristic, though: the purported ability to extend life (or at least, youth), improving your general health and specific ailments alike.

Xtend-Life supplements are all made at the company’s facility in Christchurch. Most of its raw ingredients are developed, processed, and packaged in-house. All of its products are created using cruelty-free standards, and nothing is tested in animals. The company routinely sends samples of its protein powders and supplements to an external facility owned by the government of New Zealand for third-party purity testing.

At first, Xtend-Life dietary supplements were all meant to increase the efficiency of the body as a whole. However, the company has branched out its product offering exponentially over the last decade. Now it includes more specialized supplements that address specific conditions or systems (like heart health, high blood sugar, and yeast infections).

There is still a strong emphasis on holistic health and the idea of different supplements acting synergistically (boosting one another’s effects). Xtend-Life expresses this potential via “Core Wellness packages” that bundle supplements that go well together.

Xtend-Life’s health supplements for men are mainly targeted at men over 40 years old, who are first beginning to see the effects of aging and dwindling testosterone levels.

This product line includes:

• Omega 3 and DHA supplements. Meant to improve brain function, these gel capsules contain essential fatty acids made from New Zealand Hoki fish, and DHA, a testosterone precursor. Prices start at $17.95.
• Kiwi Klenz. This digestive enhancer is made mostly from Kiwi extract. It promotes regular bowel movements. Prices start at $35.50.

These supplements are all sold in bottles of 60.

In addition to individual bottles, you can also buy the following Core Wellness packages, which all include three bottles of different supplements, meant to act in sync.

Formulated primarily for women ages 25 and older, the women’s health supplements from Xtend-Life are meant to balance your nutrition and support a harmonious endocrine system. This can help prevent many of the distressing symptoms of PMS, perimenopause and more.

These supplements are all sold in bottles of 60.

Xtend-Life’s line of children’s supplements is intended for kids between the ages of 4 to 12.

Xtend-Life’s Zupafood products were all created to provide highly concentrated and standardized functional foods. Rather than bland capsules and tablets, however, Zupafood products can be turned into fizzy drinks and protein shakes.

This product line includes:

No matter how distant the company’s headquarters may be (at least from Americans), buying from Xtend-Life is as simple as ordering from any online retailer. You can browse products by category or by health concern, in addition to using standard site-wide search when you’d like.

The Skincare and Superfood sections are limited enough that you can browse around them easily. Xtend-Life’s supplement range, on the other hand, offers a wider set of options. It isn’t hard to confuse two different Core Wellness packages, so make sure to check the total number of bottles before adding a package to your cart.

At checkout, pay using any major credit card (VISA, MasterCard, AMEX, or JCB), as well as PayPal or AliPay. Xtend-Life protects you on the payment page using EV-SSL encryption, the strictest currently available standard, and we didn’t find any reports of fraud. The website can process payments in US Dollars, Australian Dollars, New Zealand Dollars, and British Pounds.

Xtend-Life offers several standard and premium shipping options that cater to clients all around the world. At first glance, these are surprisingly budget-friendly for international shipping standards:

• Standard shipping for orders under $60 is just $6.50
• Standard shipping for any orders $60 or above is free.
• Premium or priority shipping will vary by region (USA and Canada, South Pacific, East Asia, or the rest of the world). Rates start at $9.50 for orders over $60.

Standard shipping uses New Zealand Post Priority Air Mail, and delivery can take between 10 to 20 days. Premium shipping is done via DHL and usually takes between 4 to 10 days.

You should take into consideration that these prices and timeframes are only valid until the package arrives into the country of destination. Customs and import fees may increase the total price of the order, while also adding a few extra days of waiting time.

Xtend-Life supplements are all designed for long-term use. Because Xtend-Life is confident you’ll find benefit from using its supplements, the company has designed a “membership program” that helps its long-term clients to access additional savings.

An Xtend-Life Club membership lets you set up automatic subscriptions and access an additional 10% discount on any order placed. It also includes a few minor marketing perks, such as customized alerts whenever specific products go on sale. Membership is free.

All Xtend-Life products come with a 365-day guarantee. During this time, if you are not satisfied with the product, you can simply email them and ask for a return and refund – a refreshingly easy, customer-friendly process.

Xtend-Life staff is helpful and courteous at all points of this process. The company seems to have no interest in delaying the refund process and it doesn’t harass you with satisfaction surveys, nor does it try to discourage you from returning the items. However, you will need to pay the cost of shipping the items back to New Zealand.

Xtend-Life’s privacy policy conforms to what you would expect from any good online retailer. All payment information is encrypted and it is not stored directly by the company. However, Xtend-Life does collect cookies, with your permission. If you sign up for any of their newsletters, it will send your first name and email address to a third-party company that handles its newsletters.

All orders are sent in plain, sturdy packaging, so they won’t attract unusual attention whenever they are delivered. The company labels its products as “Dietary Supplements” or “Cosmetics” (for the KAPALA skincare line) – information that will be declared on any Customs forms.
