The Delivery Paradox
In micronutrient science, "intake" does not equal "status." Just because a vitamin is present in a food or a fortificant does not mean it reaches the bloodstream. Bioavailability is the fraction of an ingested nutrient that becomes available for use and storage in the body. Our research is dedicated to identifying the barriers—chemical, physical, and biological—that prevent nutrients from reaching their target tissues.
The Three Pillars of Bioavailability
Our research framework focuses on the "Big Three" factors that dictate nutrient success:
1. Chemical Form (Speciation)
The molecular structure of a nutrient determines how easily the body can break it down.
- Chelation: We study how minerals bound to organic acids (like Magnesium Bisglycinate) outperform inorganic salts (like Magnesium Oxide).
- Active vs. Inactive: Researching the necessity of methylated B-vitamins for individuals with specific genetic markers (like MTHFR) who cannot convert standard folic acid.
2. Food Matrix & Synergies
Nutrients rarely act alone. They work in complex synergies that can either "lock" or "unlock" their potential.
- The Enhancers: Investigating how Vitamin C increases non-heme iron absorption and how Vitamin D is required for calcium transport.
- The Inhibitors: Quantifying how phytates in grains, oxalates in spinach, and tannins in tea can bind to minerals and prevent them from being absorbed.
3. Biological Individualism
Age, gut health, and genetics play a massive role in absorption rates.
- The Microbiome Factor: How healthy gut flora facilitates the synthesis and absorption of Vitamin K and certain B-vitamins.
- Aging & Acidity: Studying how reduced stomach acid in older populations hinders the breakdown of Vitamin B12 and Calcium.
From Lab to Life
By focusing on bioavailability, our advocacy ensures that global fortification efforts aren't just "checking boxes" with cheap, poorly absorbed nutrients. We push for High-Bioavailability Standards in public health policy, ensuring that every milligram delivered is a milligram utilized.
