Vitamin & Mineral Capsule Manufacturing

Supplement Brands

Vitamin and mineral capsules remain one of the most stable, regulated, and scalable categories in the global dietary supplement industry. In the United States and Europe, micronutrient supplementation continues to expand across immunity, metabolic health, prenatal nutrition, longevity, and general wellness positioning.

For brands, the challenge is no longer whether to enter the vitamin market. The real question is:

Which capsule manufacturer can deliver regulatory consistency, dosing accuracy, and long-term supply reliability?

At Runxin Biotech, we specialize in Vitamin & Mineral Capsule Contract Manufacturing, providing OEM and private label production for brands targeting regulated Western markets.

This page is designed to support procurement teams, brand founders, and sourcing managers evaluating a capsule manufacturing partner for micronutrient-based products.

Why Vitamin & Mineral Capsule Manufacturing Requires Specialized Control

Unlike botanical supplements, vitamins and minerals involve:

Strict dosage accuracy requirements

Stability sensitivity (light, moisture, oxidation)

Bioavailability considerations
