Science That Works

Let's face it everyone is different, we all have different needs both internally and externally. Traditional gyms and trainers rely on guessing, averages, and a what works for one will work for all” theory. You typically hear things like drink a gallon of water each day while this could possibly be true for many individuals, you may in fact need more or less water. This ideology also holds true with meal planning as well as creating fitness plans. Sure it may work but are you maximizing your time? When you introduce science into your health and fitness plan you achieve optimal gains that last a lifetime. Your body is unique which means that your solution must be unique, your trainer has as much of a chance guessing the best meal plan for you as he/she does guessing your blood type. Stop the guessing and come to RNS for the REAL answers.

FAQ about our testing

For example, people who are diagnosed with wheat intolerance may also be intolerant to the chemicals used to manufacture the bread or other food item containing wheat.
Our test is the only test that identifies these chemicals.

Hay fever sufferers can be intolerant to grass, wheat or tree pollen.
Our test identifies the exact pollen which causes your hay fever.

A common cause of skin disorders is an intolerance to lettuce.
Our test not only identifies if you are intolerant to lettuce but the type of lettuce e.g Kos.

Intolerances to chemicals and non-food items causes identical symptoms to those of food intolerances so it is essential that both are tested at the same time.

Our test is currently the only test available on-line that tests both food and non-food items.

Everyone suffers intolerances but not all will lead to visible symptoms or cause major problems.
This is why a one-stop test is important and you do not have to then pay extra to discover what those intolerances are.

Your intolerances can alter over time and are affected by your exposure to the item and your environment.

If you have unexplained skin, respiratory or digestive problems you should have your intolerance levels tested regularly.
