Behind the tonics

Goldthread was founded by William Siff—licensed acupuncturist, clinical herbalist, and life-long ethnobotanical adventurer with over 20 years of experience working with natural medicine. He formulated our line of tonics based on the incredible results he saw working with plants in his clinical practice. Goldthread is the first of its kind in an entirely new category of plant based, functional beverages that empower our daily rituals and strengthen the foundation of our health and happiness.


As a team of innovators and disruptors, the Goldthread brand evolved from a grassroots movement into a worldwide effort to support and promote plant-based healing traditions and the cultures that still preserve and practice them. Our ingredients are sourced through a network of direct relationships with farmers to maximize the quality of the herbs, prosperity for the farmers and long-term sustainability for our planet.


The Goldthread Difference

Supporting Small Farms

We work exclusively with small family farms around the world that provide the best, hand-picked ingredients.

Commitment to Sustainability

All of our tonics are micro-brewed in the USA, and bottled in glass with metal caps—yay for no plastic!

Made for You

We use fresh-squeezed citrus juice to keep our tonics shelf-stable & delicious, for traveling to the gym or around the world.
