Time-release Multivitamins: The Science Behind Better Absorption
Discover how Stack's time-release multivitamin technology improves absorption, reduces nutrient clashes, and delivers better results for long-term wellness.

Introduction: Why Supplement Absorption Matters
When it comes to multivitamins, it's not just about what you take. It's about what your body can actually absorb. Traditional supplements often deliver everything at once, which can cause nutrients to compete and reduce effectiveness. While important, that approach misses a critical factor: timing. At Phi Health Sciences, we have invested heavily in delivery technologies to create a next-generation time-release multivitamin designed for better absorption, efficiency, and results. Stack was born out of that research.
Why Nutrient Timing Matters in Supplement Absorption
The body is not a static system. Nutrients compete for absorption, enzymes fluctuate throughout the day, and the gastrointestinal tract can only handle so much at once. For example:
- Calcium and magnesium, while both essential, compete for transport channels in the gut. Taking them together in large amounts reduces the efficiency of each.
- Vitamin C enhances iron uptake but may reduce the absorption of certain other minerals if not separated.
This explains why many people who take multivitamins see limited results. It's not just about the formula. It's about delivery and timing.
What Are Time-release Multivitamins?
Stack was designed around a simple but powerful principle: nutrients should be delivered when the body can best use them. Using advanced micro-bead technology, we separate vitamins, minerals, and bioactives into distinct layers, each dissolving at specific times during digestion.
- Immediate release: Nutrients your body needs right away (like B vitamins).
- Delayed release: Compounds that bypass the stomach and are absorbed in the small intestine.
- Sustained release: Nutrients that trickle in over hours for steady support (like vitamin D).
This approach allows synergistic nutrients to be paired together, avoids nutrient clashes, improves bioavailability, and provides longer-lasting benefits.
The Science Behind Stack's Supplement Delivery System
Our innovation at Phi Health Sciences was guided by three core principles:
1. Absorption Kinetics
Each nutrient has a known absorption curve. By aligning release profiles with these curves, we increase efficiency. For instance, B vitamins are water-soluble and benefit from rapid release, while fat-soluble compounds such as vitamin D require slower, sustained release.
2. Nutrient Synergy and Separation
Stack separates competing minerals, allowing each to be absorbed without interference. At the same time, it pairs synergists, such as vitamin C with iron.
3. Lifestyle Integration
Stack simplifies this into one smart system that works seamlessly with daily life and syncs with your body's rhythms.
Benefits of Time-release Multivitamins
The innovation behind Stack reflects a broader shift in nutritional science. Switching from traditional vitamins to Stack's time-separated release system offers measurable advantages:
- Improved nutrient absorption and efficiency
- Fewer nutrient clashes (better bioavailability)
- Steady energy, focus, and immune support
- Simplified daily routine with one capsule instead of multiple pills
The Future of Multivitamins
The launch of Stack reflects a broader shift in nutritional science, away from "one-size-fits-all" pills and toward intelligent, science-driven formulations. With time-release technology, supplements can finally deliver on their promise: nutrients that your body can absorb, use, and benefit from.
