Bio-what--Why-You-Need-to-Understand-What-‘Biomarkers’-Are-Now

Sports Test

Absolutely. Carrying out a Biostarks test will enable you to find out what your micronutrient deficiencies and excesses are. Following these results, you will be able to modify your diet thanks to our advice. Micronutrients have a direct link with sports performance. Improving them is also improving your sports performance.

The Sport Biostarks test is divided into 4 categories: endurance, strength, performance and recovery. Thanks to the different categories of the sport test, you can immediately see where your strengths and weaknesses lie. You will then be able to work on your weaknesses and improve yourself through our nutritional advice.

Deficiencies or excesses have a direct link with sports performance. Indeed, they can lead to chronic fatigue, injuries, lack of energy but can also influence your stress. These disorders will lead to a decrease in sports performance.

In addition to a physical activity adapted to muscle mass gain, our tests can allow you to know which micronutrients you should pay attention to. These micronutrients are directly related to strength or recovery, which are components of muscle mass gain.

Nutrition Test

The results delivered by Biostarks include personalized nutritional recommendations to help you bring your biomarker levels into their optimal ranges. Following these recommendations can help you improve your general eating habits.

The Science

Your results will be as accurate as conventional lab results. Our accredited labs use rigorous scientific methods, state-of-the-art mass spectrometry machines, and unique algorithmic sequences to ensure unsurpassed sensitivity and specificity of results. Please do note that for accurate results, you should follow the instructions contained in your biomarker test kit.

A biomarker is a distinctive biological or biologically derived indicator (such as a molecule or other measurable substance) of a process, event, or condition. Your body is a treasure trove of these indicators.

The number of biomarkers we measure varies, depending the test. You can find the exact number for each test on their specific page.

These biomarkers have been carefully selected by the Biostarks Research and Development team based on the impact they have on specific functions and processes of the human body, and grouped into categories befitting our different test kits.

Biostarks uses high resolution mass spectrometry multiplex laboratory technology coupled with unique algorithmic sequences to measure and format thousands of molecular markers found in a few drops of fluid.

We do not recommend this, as stopping supplementation or a medication can have serious consequences. If you have any questions, we advise you to contact your physician.

Supplements and/or medication can affect your biomarker levels in different ways depending on the specific supplement/medication. This is something to consider when interpreting your results. If you have any questions, we advise you to contact your physician or contact us at contact@biostarks.com

Your Results

Your result is summarized into a score, based on how many of your biomarkers are in their optimal ranges. Ideally, you want to be as close to 100 as possible. A low number is no cause for panic, but we recommend you follow our recommendations to correct any excesses or deficiencies.

Your results come complete with personalized recommendations, complete with lists of foods and portions you should incorporate into your diet to help you reach the optimal level for each biomarker!

For each result, 10 different foods will be suggested. If you are allergic to one of them, you can include the other 9 foods in your diet. If you follow a vegetarian, vegan, keto or gluten-free diet, you can choose your specific diet in the tab “my identity”. The recommended foods will be adjusted to reflect this setting.

You can click on any biomarker to see its specific range graph which represents the recommended range for each biomarker and where your result is situated in relation to it.

If your results are outside the limits of a biomarker range (e.g. Vitamin D, magnesium, etc), then you are either deficient or in excess. We recommend you follow our personalized recommendations to reach the optimal range.

Your unique biomarker map regroups all the biomarkers included in your test, and presents your results in an easy-to-understand visual summary. The color code is a simple way to visualize which biomarker levels are optimal and which ones need attention.

In the “science” tab on biostarks.com you will find the biomarkers glossary and their description.

Please feel free to consult your physician if you see any unusual values or if you woud like some further explanation of your biomarker levels and their implications. You can extract your results as a PDF and send it to your physician.

If you are outside of the reference range for 1 or more biomarkers, it is recommended that you follow your personalized recommendations.

To request the cancellation of your personal data, you must send us a written request at contact@biostarks.com

If your test was purchased by a doctor/dietician, they will be able to acess your results. If not, you can export your results as a pdf and share it with them.

Some biomarker levels can change relatively quickly while others, such as Magnesium, can take several months to change in a significant way. Thus we recommend taking the test every 3 months so that your progress is noticeable.

Our team of nutritional expert has conducted extensive research using the USDA (United States Department of Agriculture) database. The USDA provides the exact composition of thousands of foods, and we base ourselves on this data when delivering personalized nutritional recommendations.

We recommend taking a test every 3 months to check your progress in optimizing your biomarker levels. If your biomarkers are within their optimal ranges, we recommend you take the test twice a year, or if you have gone through a substantial lifestyle change (ran a marathon, changed your diet drastically, etc).

The foods shown in the “my top foods” section are the compilation of foods the most relevant to your specific deficiencies/excesses across all biomarkers tested. We recommend adding these foods to your diet as a priority. The foods shown by clicking on a specific biomarker are foods that are not individual to you, but rather the foods that are richest in that specific micronutrient.

Though your results are directly correlated with your diet and lifestyle, there are additional factors that can affect your results. For example, an athlete who sweats a lot can experience increased mineral loss. His diet may not fully cover his mineral expenditure, thus the athlete may be deficient in certain minerals even though his diet and lifestyle are healthy.
