Ingredient research · Open questions · Clear limits
Traditional use begins a conversation. Research helps us ask better questions. Here is how we separate an ingredient, an extraction method, and a finished formula.
A randomized trial of Reishi, with or without Cordyceps, found no significant improvement in the measured cardiovascular risk factors in people with metabolic syndrome. That result matters. It does not support clinical benefit claims for KUZŪ.
Read the randomized trial ↗Wild Ophiocordyceps sinensis, cultured mycelium and Cordyceps militaris should not be treated as interchangeable. Check the species, material, dose and preparation before applying a study to a bottle.
Explore a cultured Cs-4 study ↗Extraction research examines how process conditions affect the compounds recovered from Reishi. Laboratory antioxidant tests do not establish effects in people, and a published method does not verify our production process.
Read the extraction study ↗No clinical trial of the finished KUZŪ Reishi Cordyceps tincture is presented here. These references provide ingredient and process context, not proof that this product prevents, treats or cures disease. Batch laboratory reports answer a different question: what was measured in that sample.

Bhutan is the beginning of the story. A traceable batch is where the details belong.
Search your bottle’s origin →Our Cordyceps supplier from Gasa represents his community and around 30 fellow highland foragers. Meet the relationship behind the ingredient, then follow your bottle’s batch record for its specific source.
Meet our sourcing communities →Dambar Gurung represents his farm and community in our Reishi sourcing relationship. People, their work and their connection to the land are central to the story of KUZŪ.
Explore our Reishi relationship →Certificate ABSCH-IRCC-BT-280228-1 records prior informed consent and mutually agreed terms. It lists 11 April 2025–10 April 2030 and specifies Non-Commercial use. It is not evidence of commercial authorization, Cordyceps coverage, product safety, or efficacy.

A liquid supplement bringing together Reishi and Cordyceps Sinensis. Check the current product label for the complete ingredient list, amounts per serving and directions. Ingredient research does not establish benefits for this finished combination.
Solvent choice influences which compounds an extraction can recover. Water and ethanol are studied in mushroom extraction, but the result depends on the material and process. “Dual extracted” alone does not tell you the amount of a compound per serving, absorption, or clinical effectiveness.
Our exact process conditions and finished-product specifications should be read with the approved manufacturing and batch records. We do not claim that KUZŪ uses the ultrasonic method described in the linked study.
Read extraction researchFollow the directions and serving size on your current bottle. We do not translate doses used in studies of other preparations into drops of KUZŪ. Keep out of reach of children.
No supplement is suitable for everyone. Review the ingredient and alcohol information before use. If you are pregnant or breastfeeding, take medicines, have a health condition, or are unsure whether this product is suitable, ask a qualified healthcare professional before using it.
A code such as A001 connects to an active, published origin record when one is available. A identifies Reishi Cordyceps Tincture; 001 is the batch identifier. The planned batch size is 1,000 units, not a unique serial number for each bottle.
The record can include ingredient sources, consented farmer profiles and laboratory documents. An unpublished record is not proof of failed testing; contact us for the relevant documentation.
