Why Nature Favors Consistency

Nature’s recovery model is built on consistency. Whether you’re a lifelong athlete or a health-conscious parent, your body thrives on steady nourishment. 

The natural world doesn’t deliver nutrients in abrupt bursts. Instead, it provides a gradual, ongoing supply—think of how a river nourishes its banks over time, not in a single flood.

Your body’s recovery processes—muscle repair, hydration, and energy replenishment—are continuous. They don’t stop when your workout ends or the sun sets. To truly support these processes, your nutrition should match this steady rhythm.

Choosing the Right Supplement

When it comes to supplements, there’s no one-size-fits-all. You’ll find different types—immediate-release, sustained-release, and chewable—each made to fit different needs:

• Immediate-release: Ideal for fat-soluble nutrients—alpha lipoic acid, coenzyme Q10, omega-3 fats—to be taken with food for optimal absorption.

• Chewable: Ideal for active ingredients that work directly in the digestive tract like zinc L-carnosine, prebiotics, phytosterols.

• Sustained-release (SR): Ideal for electrolytes and water-soluble vitamins like B vitamins and vitamin C, botanicals, and specialty nutrients to promote optimal absorption and tissue retention.

Where sustained release really shines is when you need a steady stream of nutrients, so your body gets the most benefit throughout the day.

The Sustained-Release Advantage

Sustained-release supplements aren’t just convenient—they’re a smart way to help keep your energy up and feel your best whatever your day brings.

For athletes, it can mean powering through to the finish line instead of hitting a wall mid-race. For active seniors, it’s the difference between feeling vibrant and energized versus struggling to keep up as the day wears on. For families, it’s about supporting well-being throughout the day—not just for a fleeting moment. In other words, with sustained release, you get nutrients that work with you, hour after hour.

The Science Behind Sustained-Release

Sustained-release (also called time-release or extended-release) supplements are engineered to mimic nature’s gradual approach. These formulations are designed to release nutrients slowly over several hours, providing a consistent supply that your body can absorb and use efficiently.

How Sustained-Release Works

• Gradual nutrient delivery: Ingredients are embedded in various types of slow-release matrices, including a vegetable wax matrix—one of the most effective delivery systems.

• Optimized absorption: Your body has more time to absorb and utilize nutrients, reducing waste and maximizing benefits.

• Stable support: Slow and steady nutrient delivery helps keep your blood levels stable, so you get consistent energy, hydration, and recovery support—without the rollercoaster effect of spikes and crashes.

Real-World Benefits: What the Research Shows

1. Improved Nutrient Absorption and Bioavailability

Consider vitamin C, a favorite supplement for athletes, active adults and seniors. Your body is great at absorbing vitamin C, but only up to about 200 mg at a time. Take more all at once, and your body absorbs a lot less and gets rid of the rest in your urine. It’s a key reason Endur-C® Vitamin C with Rose Hips is formulated for sustained-release delivery. Instead of releasing all the vitamin C at once, these tablets release it slowly over several hours to match how your body naturally absorbs vitamin C.*

2. Optimal Recovery and Less Waste

With slow, steady nutrient release, your body is able to absorb and use more of the nutrients you consume. This not only supports better recovery but also means you’re not wasting your investment on nutrients your body can’t use all at once.

3. Enhanced Compliance and Convenience

Sustained-release supplements often require fewer servings per day, making it easier to stick to your routine—an important factor for athletes, busy families and active seniors alike.
