# Sourcing Quality Usnea / Usnic Acid

Product quality matters more than usual with usnic acid.

### Why sourcing is a real issue

Most commercial tinctures are not standardised for exact usnic-acid content.

That means dose precision can be poor unless the product comes with stronger quality support.

### What to look for

* clear herb-to-solvent ratio
* alcohol percentage
* certificate of analysis where possible
* supplier transparency
* realistic short-term usage guidance

### Why this matters clinically

With a compound like UA, weak standardisation affects both:

* effectiveness
* safety

### Example sourcing notes

Examples cited here as practical options include:

* US option: [Mountain Rose Herbs Usnea Extract](https://mountainroseherbs.com/usnea-extract)
* Australia option: [Maha Farm Usnea Tincture](https://mahafarm.com.au/2024/02/22/usnea-tincture/)

These are examples, not endorsements.

### Bottom line

With Usnea, sourcing is not a minor afterthought.

If the product is vague, the whole dosing conversation gets weaker.

### Practical note

If a clinician-level protocol depends on accurate usnic-acid exposure, look for the best available documentation on strength and composition rather than assuming all tinctures are interchangeable.
