Location: Kitzbühel

Specialization: Artisanal silymarin, small-batch milk thistle extract, premium botanical extracts for niche markets

Tyrolean Botanicals & Co. is a boutique supplier that caters to niche markets and specialty brands. Based in the picturesque town of Kitzbühel in the Tyrol region, the company prides itself on artisanal production methods and attention to detail, making it a favorite among craft supplement brands and luxury wellness companies.

Unlike large-scale manufacturers, Tyrolean Botanicals produces silymarin in small batches (typically 50-100kg per run) using traditional extraction techniques combined with modern quality control.

Their extracts come with a "terroir report," detailing the origin of the seeds and the extraction process, allowing brands to share a compelling narrative with their customers.
