Science Intro - Rootine

Intro To The Science

This serves as a basic introduction to primary scientific principles that guide our data-based personalization.

The Rootine approach combines nutritionally relevant data from your lifestyle choices, DNA (genetics), and blood values to create a unique nutrient profile for you.

The Data We Use

Each type of data plays a role in determining your unique nutrient needs. Data points are used to contextualize each other and build a model to determine the type and amount of each nutrient to meet your ideal daily intake.

  • Lifestyle: Our 19-question analysis provides information about your size, age, weight, biological gender, activity level, dietary preferences, family life, and more. This data is used directionally to create your baseline range for each nutrient.
    • Example: If you eat a vegan diet, we know you likely need more vitamin B12.1, 2, 3
    • Example: If you avoid dairy, we know you likely need more calcium.4, 5, 6
    • Example: If you are a female and have a heavy menstrual flow, we know you likely need more iron.7, 8, 9
  • DNA: The science of nutrigenetics details how slight variations in your genes can alter how you absorb, metabolize, distribute, and excrete nutrients, thus impacting the type and amount of each nutrient you need. We assess 50+ of these variations and layer the impact into your profile.
    • Example: A variation in the NQO1 gene makes your body less efficient at activating CoQ10. We correct by increasing other antioxidants in your formula.10, 11, 12, 13, 14
    • Example: A variation in the VDR gene makes vitamin D bind less efficiently to its receptor. We correct by increasing your vitamin D to achieve a normal level of receptor activation.15, 16, 17, 18, 19
  • Blood: Blood nutrient levels have long been the gold standard in recommending supplements and guiding dose. Changes (or lack of positive change) over recurrent blood tests is also used to determine if the dose needs further increase, a decrease, or if it is at the ideal amount.

We combine peer-reviewed research with clinical expertise to create the data modeling (i.e. algorithm) that generates the bespoke formulas.

In some cases, the analytics process is straightforward; If a user’s blood value of vitamin D is too low ⮕ increase the amount in their formula.

In other scenarios, it is far more complex; the user is a male, vegan, and indicates low energy ⮕ likely indicates an increased need for iron; however, the user has a double HFE gene mutation which makes supplemental iron poisonous ⮕ remove all iron from the formula.

Overall, our science team utilizes scientific research (and our PhDs) + clinical experience (from our MDs, DOs, RDs, and PharmDs,) + sound logic to combine the numerous points of data that influence the final recommended dose for each nutrient.
