Why do I need to retest?
We recommend retesting your nutrient levels every 3 months to make sure our supplements are working for you and to check for new deficiencies or toxicities. Our nutrient needs tend to change due to adjustments in eating habits, which can be purposeful or natural. For example, many people who need a vitamin D supplement in the winter won't need one in the summer.
If you don't want to retest, you can delay your Nutrient Test for up to a year from your initial test. In order to remain true to our values rooted in scientific accuracy, we require all of our customers to retest at least once a year.
