Thorne: Science-Based Nutritional Supplements

Thorne is a brand of science-based nutritional supplements, founded in 1984 in the United States and now headquartered in Summerville, South Carolina. The company started with a single product and grew to become the most recommended clinical brand by healthcare professionals.

Its mission is clear: to empower every person to take control of their health through rigorously tested and scientifically validated formulas, at every stage of life.

Quality Standards and Certifications

Thorne's commitment to quality begins long before the final product. Each supplement undergoes four rounds of testing, ingredient validation, and independent certifications that ensure purity, potency, and bioavailability.

The brand's facilities are certified by NSF International — a benchmark of excellence in supplementation — and comply with Good Manufacturing Practices (cGMP). Thorne also holds an "A" rating from the Australian TGA, often described as the most stringent regulatory agency in the world.

More than 20 products in the range are NSF Certified for Sport®, tested for the absence of hundreds of substances prohibited in high-competition sports — the reason why over 100 professional teams trust the brand.

Product Range and Specialized Nutrition

Thorne develops formulas with bioavailable ingredients — such as methylcobalamin (vitamin B12) and magnesium bisglycinate — for superior absorption, avoiding gluten, artificial colours, and unnecessary excipients. The catalogue covers several hundred products, organized by health objective.
