Premium organic kelp 
for health & wellness

Sourced from the pristine waters of Iceland, Thorvin kelp ingredients offer unmatched purity and nutrient density for your formulations.

Thorvin Kelp Ingredients™— the trusted source of nutrient-rich kelp from Iceland’s pristine waters

Thorvin is a global leader in sustainably harvested kelp ingredients, known for exceptional purity and nutrient density. For over 30 years, Thorvin has sourced premium kelps from the mineral-rich fjords of Northwest Iceland—nourished by glacial rivers, geothermal vents, and ocean currents—and processed them to preserve their full nutritional value.

Delivering certified organic ingredients, premium formulas, and custom blends, Thorvin enables manufacturers to formulate with confidence, consistency, and a clear focus on consumer health and product performance.

Thorvin kelp is harvested from the purest, mineral-rich Icelandic waters for unmatched nutrient content.

Sea plants — nature’s most powerful bioaccumulators

Sea plants, especially cold-water kelps, are among the most nutrient-dense plants on Earth. Unlike land plants, sea plants feed directly from seawater through their entire surface—absorbing a full spectrum of minerals and trace elements.

What makes kelp a superior ingredient

Full mineral spectrum

Seawater contains all essential minerals — in ratios similar to human blood — making kelp a potent natural source of nutrients.

Functional & versatile

Supports thyroid health, detox, metabolism, immune balance, and skin nourishment.

Cold-water grown

Slow-growing in cold, mineral-rich waters, premium kelps concentrate higher levels of vitamins, enzymes, and amino acids.

Naturally sustainable

Requires no fertilizers or irrigation and regrows quickly — making kelp one of the most sustainable crops on Earth.
