ClearZen — Rhodiola rosea 500mg, Ashwagandha KSM-66 1500mg and Shilajit — 90 capsules, a 45-day supply.
- Three botanicals with centuries of use across three distinct traditions — in a single daily formula
- Ashwagandha KSM-66, Rhodiola standardised to 3% Rosavins and 1% Salidrosides, and Shilajit at 60% Fulvic Acid
- For those who want a complete adaptogen routine without managing multiple bottles
Three Traditions, One Formula
Rhodiola rosea grows in cold mountain regions across Scandinavia and Siberia, where it has been used for centuries in traditional practice. Ashwagandha has been central to Ayurvedic tradition for millennia. Shilajit is a mineral-rich resin found in Himalayan rock formations, long valued in traditional practice across Central Asia and the Himalayas. ClearZen brings all three together in a single, considered daily capsule — for those who want an adaptogen formula built on genuine historical depth.

More Than Any Single Adaptogen
Many adaptogen supplements focus on a single botanical. ClearZen combines three of the most historically recognised adaptogens in one formula. Black Pepper extract (95% Piperine) is also included to support bioavailability, alongside zinc, vitamin D3 and vitamin B6 as part of the complete formulation. Two capsules a day covers the full formula — no juggling multiple bottles or separate purchases.
Part of a Considered Daily Routine
Two capsules a day with food. ClearZen tends to appeal to those who have researched adaptogens and want to consolidate — whether replacing several individual products or starting a multi-adaptogen formula for the first time. Each botanical is included at the levels most widely discussed in traditional use and the scientific literature. One bottle: 45 days of consistent daily use.
The Background, Explained Simply
Rhodiola rosea has been used in Siberian folk medicine and by Scandinavian communities for over a thousand years, and has been the subject of published human research examining its use in physically and mentally demanding conditions. Ashwagandha (Withania somnifera) is one of the most important plants in Ayurvedic medicine — where it has been in continuous use for at least 3,000 years — and KSM-66 is one of the most widely studied commercial ashwagandha extracts, having appeared in numerous published human trials. Shilajit has been valued in Himalayan traditional medicine for centuries; its Fulvic Acid content is the component most frequently discussed in the modern scientific literature. All three are included here at the levels and standardisations most commonly referenced in that body of research.
