Xtend-Life's Uncompromising Quality

This is taken directly from Xtend-Life's website, with the only amendment's from "we" and "our" to "they" and "theirs". I am inspired by Warren's life story and Xtend-Life's principles, and I felt that it is an integral part of my journey to be part of the Xtend-Life affiliate team, and I also think that Xtend-Health.com readers should read and understand who and what drives the founder of Xtend-Life to build this brand since 2000.

For more information, please visit Xtend-Life website directly here.

Unlike most of the other supplement companies, they fully own and control the manufacturing of all the products they develop through their fully-owned manufacturing company Natural Products (NZ) Ltd, which is a member of the Xtend-Life group (refer to the link Company Ownership).

Their Facility

Natural Products (NZ) Ltd. operates from a purpose built facility in Christchurch, New Zealand. Both the facility and processes are registered and audited by the local council authority Environmental Health Licensing unit, directly responsible to the New Zealand Ministry of Health. The company has implemented hazard analysis critical control point programs (HACCP) and good manufacturing practices. This enables the company to rigorously control the quality of all raw ingredients and comply with GMP processes and standards.

The equipment used is all state of the art and includes some equipment rarely seen in either supplement or pharmaceutical manufacturing companies, such as a special 3D blender.

This blender ensures a much better homogeneous mix that is simply not possible with normal blenders. Through its unique action it is possible to avoid stratification (division) of ingredients in multi complex formulations.


It is easy to talk about quality…but few manufacturers actually achieve it! This statement is born out by the significant number of supplements on the world market today that are either not true to the ingredient label, or have contaminants present. The reasons for this are manifold. It can be due to:

  • Dishonest management.
  • Pressure from shareholders to cut corners and improve profitability.
  • Poor manufacturing processes - Substandard raw ingredients Quality can ONLY be achieved if the correct steps are taken and there are no short cuts.

The Production and Testing Process

The following is a simple explanation of the steps and processes they take with tablets to ensure that the quality of products we produce are unsurpassed by any other manufacturer in the world. Similar processes are taken with their liquid soft gels and capsules.

Step 1. Raw Ingredients

For each raw ingredient there are a multitude of manufacturing suppliers scattered around the world. To most people there would seem to be no difference between the same ingredient supplied by any one of these different manufacturers. But…in reality there can be an enormous difference in efficacy and potency, just as there can be an enormous difference in price.

When they source their raw ingredients price is given a very low priority. Their highest priority is quality…which means efficacy and purity. This is crucial as the finished product can only be as good as the raw ingredients used. When choosing a supplier they do not just rely on Certificates of Analysis when making a decision.

They do a series of crosschecks before purchasing including independent laboratory testing. With most ingredients there is a wide range of potencies available, particularly for herbal extracts which can have anything from 5% to 90% of the active ingredient present depending upon the ingredient. They have specific requirements and zero flexibility when selecting their raw ingredients. If they do not conform to the specifications they need for a particular formula they will not use them.

Here is an example of a typical test result that they may receive for a raw material potency test,  the example shown is for Resveratrol.  This analysis was done by Cawthron, a New Zealand laboratory that they use on a regular basis.

Step 2. The Quarantine Process

This process begins when the raw ingredients arrive in their facility. At that point a sample is taken of the product and the ingredient is placed into a quarantine area until an analysis is completed on the sample.

This analysis includes:

  • Microbiological testing including total plate counts for bacteria, mould and yeast, coliforms, E-coli and Salmonella.
  • Potency testing, to confirm that the active ingredients are present in the amounts stated in the manufacturers COA (Certificate of Analysis).
  • Heavy metal testing. We check that there is no contamination with Mercury, Lead, Arsenic or Cadmium.

Providing the sample passes ALL tests it is then released for use in the manufacturing process. All materials that are sensitive to room temperature, such as enzymes, are stored at all times in chillers.

Step 3. The Weighing Process

This is the start of the manufacturing process for each product. Two technicians carry out this process with one cross checking the other and maintaining a record of each ingredient. The ingredients for each batch are then grouped, ready to be used in the blending/mixing process.

Step 4. The Blending/Mixing Process

This is one of the most crucial stages. They use a variety of pharmaceutical mixers in the various blending stages and finish with their special 3D Blender. Unlike most other manufacturers, who use a ribbon type blender and mix for around 20 minutes, their blending process goes through five stages and takes 5 hours for each batch.

This is critical in order to ensure there is no stratification of ingredients and to ensure that low dose ingredients are properly and evenly dispersed throughout the mix.

Immediately below is a diagram of a typical Manufacturers Blending Process...compare this to Xtend-Life's blending protocol below that.

Step 5. The Tableting Process

The granulated powder is fed into an automatic tableter. Periodic checks are made to ensure that the hardness is within specifications.

Step 6. Friability and Disintegration Testing

After the tableting process is complete the tablets are tested for friability (not to be confused with cooking, but the tablet's resistance to breakage) and disintegration (the fragmentation and distribution of ingredients).

Their self imposed standards exceed those set out by the US and British Pharmacopoeia. Providing the tablets pass this testing then they move to Step 8.

Step 7. Enteric Coating Process

This is another sophisticated process, rarely used in the supplement industry primarily because of the cost. However, because of the complexity of many of their formulas and the sensitivity of some of the ingredients to stomach acid this is a critical step.

Most of the tablets they manufacture therefore utilize this delivery system. Enteric coating enables the tablets to pass through the stomach without the ingredients being damaged by stomach acid. This can increase the potency of some ingredients many times. It also ensures sensitive ingredients such as SAMe retain their integrity.

The process requires the application of a special polymer film to the tablet which protects the tablet during its passage through the stomach. When it reaches the upper intestine which has a different pH, the film disintegrates and passes harmlessly out of the body whilst the active ingredients are absorbed through the intestinal wall.

Enteric coating ensures active ingredients are absorbed properly and maintain their integrity.

Step 8. More Disintegration Testing

Samples of the tablets are now taken and tested for disintegration by simulating the pH levels of both the stomach and the upper intestine. Providing they pass, the tablets move on to step 10.

The protocol they follow for disintegration is that set out by the British Pharmacopeia which has tougher standard than the US Pharmacopeia.

Step 9. Microbiological Testing

A further set of tests are now carried out to ensure that the tablets have not picked up any contaminants during the manufacturing process. If this test is passed a COA is prepared for that batch and the product is released for bottling and labeling.
