The Importance of Ingredient Bioavailability

Testing to ensure bioavailability of supplement ingredients

There are many aspects of nutritional product quality, but one of the most important by far is bioavailability. After all, except for supplements exerting their functions in the GI tract, the best quality nutritional ingredients in the world won’t help anyone if they’re not able to be effectively absorbed and utilized by your body.

To ensure the bioavailability of our products, NOW regularly conducts research studies with human volunteers to assess the bioavailability of various products by measuring ingredient levels in plasma (blood). These tests help us confirm the absorption and distribution of nutrients and natural bioactive ingredients from the dietary supplements we produce.
