BIOAVAILABILITY

If you're not absorbing the nutrients, then what's the point?

ABSORPTION IS COMPLICATED

Bioavailability is a measure of how much a nutrient is able to reach its target — it’s a function of absorption (how much we take in) and secretion (how much we let out).

A nutrient must travel through your digestive tract, where it interacts with other nutrients, food and drink along the way. These interactions can inhibit absorption, meaning you may not get the full benefit of what a supplement promises. In short, a lot happens after you swallow.

A highly bioavailable supplement like ours helps your body absorb the necessary nutrients, which helps you to stay healthy.

HOW WE OPTIMIZE FOR BIOAVAILABILITY

For better bioavailability, it's important to pair certain nutrients — ones that work together to perform specific functions — and separate the nutrients that inhibit one another’s absorption, while also avoiding any other adverse interaction.

That was our MO in creating First & Foremost — we provide the right dose of each nutrient at the right time, without going over its absorbable limits and considering these four factors:

A SUPPLEMENT BACKED BY SCIENCE

Our registered dietitians formulated First & Foremost after poring over decades of nutrition research from credible sources like NHANES, NIH and the FDA for each and every essential nutrient.

Our strong understanding of common deficiencies, nutrient interactions and dietary needs led to our patent-pending, comprehensive supplement program that gives you the strong foundation you need.
