There are several DNA testing companies offering what look like very cheap tests, however, NOT ALL DNA TESTS ARE OF EQUAL QUALITY. To avoid getting an incorrect result from your test which could have devastating consequences, always ensure the following:


Sample collection and Testing

We test a number of genetic locations (known as 'loci') for each test in accordance with international paternity testing standards (including ISO 17025 guidelines) - which provides unsurpassed confidence in the paternity result. We utilise various population genetics statistics such as the Paternity Index to calculate test results. Because we guarantee a conclusive result in every case, Exact DNA provides the only DNA test you will ever need.

The lack of ongoing treatment options for "well but worried" cancer patients following successful initial treatment during the long latency that many types of cancer are known to have provides an excellent opportunity to positively intervene using appropriate dietary and lifestyle changes. Indeed, much research in recent years has demonstrated that certain naturally-occurring compounds found in small amounts in a healthy diet can be extremely beneficial in a variety of cancers for delaying cancer relapse, ameliorating some unpleasant symptoms of the disease, and prolonging survival. Very frequently however, after the completion of these studies the research teams either do not have the interest or the expertise to take their work that step further to produce an actual medicinal product and make it available to help patients. Our goal is to not only make available the latest cutting-edge research on the use of specific natural compounds proven to be beneficial for cancer, but also to offer the high-quality nutraceutical products based on this research. We aim to present all relevant research data in a readable but scientific way so an individual can be fully informed about what is known about a particular compound and the circumstances in which it may help (or not) in cancer treatment.

ALL of the data and studies presented on this site have been published in respected peer-reviewed medical and science journals. In addition, scientists and doctors with long-standing experience in cancer treatment and research have contributed to the presentation of the data shown on these pages. We've included extensive references for all studies to enable individuals who are interested in further research into of these compounds to do so. We encourage individuals to use these resources to make an informed decision about what is best for you.

We have endeavoured to provide information on all the clinical studies we can find on a given cancer type and nutraceutical component. Our aim is to provide a full and objective overview of the relevant scientific literature rather than just reporting the studies which provide positive evidence for the use of a particular component. However, in doing so we will sometimes find clinical studies which contradict the findings of other studies, yet we will present them here so you have a full understanding of the current research in the field. There are many possible reasons why some studies sometimes generate conflicting results and conclusions to other similar studies. These can include: (i) the use of different patient populations (for example a population deficient in a particular nutrient will often provide a more significant positive effect than a healthy population, or patient groups of different genetic backgrounds can respond differently to a given compound), (ii) the use of different dosages (for example some researchers will use larger amounts (so-called "mega-doses") of a particular compound which may result in differences in outcome to other studies that use a lower dose), (iii) the use of different outcomes to measure the effect (for example, a study may look at the effects of a particular compound on cancer markers in the blood, whereas another study may look at its effect purely on survival times of patients. It is possible for some compounds can show beneficial effects on one but not the other), (iv) the use of patient groups of different sizes (for example, using a small patient population can result in random effects being observed and erroneously attributed to the treatment. Generally the more individuals a study includes, the more accurate the results will be), and even different statistical methods used to analyse the data. A general rule-of-thumb is that the study which contains more patients and/or is placebo-controlled and/or double-blinded and/or uses humans rather than an animal model or in vitro system, will be the best representation of how a particular compound will work in members of the general population.

A procedure performed in vitro (Latin for within the glass) is performed not in a living organism but in a controlled environment, for example in a Petri dish or flask. In the medical sciences, in vitro generally means isolating a specific cell type only from tissue, growing it in a Petri dish or flask, and then looking at the biological effects of various manipulations to it (for example, looking at the effects of adding ascorbic acid to prostate cancer cells grown in a flask). In vitro studies are frequently used to tease out the specific cellular and molecular processes that are active in response to a given compound. Since they usually only involve a single cell type in the absence of other complex cells and tissues, they provide a much simplified background with which to study a particular treatment. However, for this very reason it is important to note that the treatment of a single population of cells growing outside the body in this way is not always representative of what happens inside the body, when the cells are engaged in much more complex interactions with each other and their environment. While in vitro studies often provide important clues as to the action of particular compounds, in the end the only truly relevant studies are those undertaken on a large population of human patients.

In vivo (Latin for within the living) is experimentation using a whole, living organism, as opposed to only parts or cells from an organism. Animal testing and clinical trials are two forms of in vivo research. In vivo testing is often employed over in vitro because it is better suited for observing the overall effects of an experiment on a living subject.

    Not all organic supplements are created equal – for example a massive 16 out of 40 nutritional supplements tested recently by the Government Accountability Office (GAO) were found to contain higher than legal amounts of pesticide residues and other contaminates. This is the often result of retailers procuring their supplements from manufacturing plants in countries with much lower safety standards, simply because they are cheap. All of our nutraceuticals are manufactured in a fully accredited pharmaceutical laboratory in the USA to the highest purity and safety standards. Every product batch is tested under the rigorous rules and procedures set by NNfA cGMP, cGLP, FDA, state and federal health departments. All of our products are therefore guaranteed to be of the highest quality.

    We provide full ingredient information, safety information, and an extensive, referenced review of scientific studies performed on each nutraceutical component and on how, why and under what circumstances each supplement is beneficial for your specific cancer type. First and foremost we want you to be fully informed about each of the components in our nutraceuticals and exactly what effects they are known to have on specific cancer types.

    To our knowledge we are the only company offering tailor-made nutraceuticals specifically for cancer patients. Our nutraceuticals are specifically formulated to the exact dosage and purity specifications outlined in the listed scientific studies for specific cancer types. Other supplement retailers focus on general health, and so do not use the specific formulation and dosage that has found to be most efficacious for specific cancers.

We would highly recommend that anyone interested in researching these nutraceuticals or cancer further look at the main database of scientific and clinical studies, PubMed. It is free to search and view abstracts from millions of scientific studies published in peer-reviewed scientific journals over the past several decades. Full tutorials and help using PubMed can be found here. While they are generally of a technical nature and intended for a scientific/medical professional audience, non-specialists should also find them extremely useful.
