Usnea Supreme Tincture – 2 fl oz

Usnea Tincture – Respiratory, Microbial Balance & Antioxidant Support

Traditional Old Man’s Beard Lichen in a Concentrated Liquid Extract

Usnea Tincture from Supreme Nutrition provides Usnea barbata, commonly known as Old Man’s Beard, a lichen with a long history of use in traditional herbal practice.

Usnea naturally contains several distinctive botanical compounds, including usnic acid, polyphenols, and other lichen metabolites that have attracted modern research interest for their antioxidant activity, microbial interactions, and effects on biofilm formation.

Its traditional use has centered especially on respiratory, throat, oral, skin, and general wellness support, while modern laboratory research has helped identify some of the compounds that may contribute to those historical uses.

Key Benefits of Usnea Tincture:

✅ Supports Respiratory Wellness – Usnea has a longstanding history of traditional use in botanical approaches focused on the throat and respiratory system

✅ Supports Healthy Microbial Balance – Usnic acid and other Usnea compounds have demonstrated significant activity against certain microorganisms in laboratory research

✅ Supports Natural Biofilm Defense – Experimental research has shown that usnic acid can interfere with bacterial biofilm formation and signaling

✅ Provides Antioxidant Support – Usnea contains polyphenols and other lichen metabolites with demonstrated antioxidant activity

✅ Concentrated Liquid Botanical – The tincture format provides Usnea in an easy-to-use liquid preparation rather than capsules or tablets

Usnea extracts and usnic acid have shown particularly notable activity against several Gram-positive bacteria in experimental research, although laboratory activity should not be interpreted as evidence that this tincture treats human infections.

What’s Inside Usnea Tincture:

• Usnea (Usnea barbata) – A traditional lichen naturally containing usnic acid, polyphenols, and other botanical compounds associated with antioxidant and microbial-defense activity

Serving size: 30 drops (1.2 mL)

Other Ingredients: Organic vegetable glycerin, distilled water, and 1%–7% organic cane alcohol.

Supreme Nutrition prepares the tincture using organic cane alcohol during extraction, removes as much alcohol as practical while retaining the extract, and then adds organic vegetable glycerin.

Product Details:

Quantity: 2 fl oz (59 mL)

Serving size: 30 drops (1.2 mL)

Suggested Use: Take 10–30 drops up to three times daily or as directed by your healthcare professional.

Supreme Nutrition's detailed guidance recommends using Usnea for short periods—generally up to two weeks—followed by a break rather than continuous long-term use.

Why Choose Usnea Tincture?

Usnea is unusual because it is not technically a conventional herb. It is a lichen, a naturally occurring partnership between a fungus and a photosynthetic organism.

That unique biology allows lichens to produce secondary compounds that help them compete and survive in their environment. One of the best-known of these compounds is usnic acid.

Modern research has found that usnic acid can affect:

• growth of certain microorganisms
• bacterial membrane and metabolic activity
• microbial signaling
• biofilm formation
• oxidative processes

This helps provide a scientific framework for understanding Usnea’s longstanding traditional reputation as a botanical used for respiratory and microbial wellness.

Usnea & Healthy Microbial Balance

The body's relationship with microorganisms is complex. The goal is not to eliminate microbes indiscriminately, but to maintain appropriate microbial balance and normal protective defenses.

Usnea and its best-studied constituent, usnic acid, have demonstrated antimicrobial activity in laboratory research—particularly against several Gram-positive organisms. Reviews also report more variable activity against Gram-negative bacteria, yeasts, and fungi.

For this reason, Usnea is most appropriately described as botanical support for healthy microbial balance and normal defense mechanisms, rather than as a substitute for antibiotics, antifungal medications, or other treatment of infection.

Usnea & Biofilm Research

One particularly interesting area of Usnea research involves biofilms.

Biofilms are organized communities of microorganisms that attach to surfaces and surround themselves with a protective matrix. Laboratory studies have found that usnic acid can interfere with aspects of biofilm development and microbial signaling.

In one well-known experimental study, usnic acid incorporated into polymer surfaces inhibited biofilm development by Staphylococcus aureus. More recent reviews continue to identify usnic acid as one of the better-studied lichen compounds in biofilm research.

These findings are scientifically interesting but do not mean that taking Usnea Tincture has been demonstrated to eradicate biofilms in the human body.

Usnea & Antioxidant Defense

Usnea also contains polyphenols and other secondary metabolites with antioxidant properties.

Laboratory analyses of Usnea extracts have demonstrated free-radical-scavenging and antioxidant activity, supporting its use as a botanical that may complement the body's normal cellular defense systems.

Who May Consider Usnea Tincture?

✔ Those seeking traditional botanical support for respiratory and throat wellness

✔ Individuals interested in maintaining healthy microbial balance

✔ Those looking for botanical antioxidant and cellular-defense support

✔ Individuals interested in botanicals studied for biofilm and microbial-signaling activity

✔ Those who prefer a concentrated liquid botanical rather than capsules

Usnea Tincture provides traditional Old Man’s Beard lichen in a concentrated liquid extract to support respiratory wellness, healthy microbial balance, antioxidant defenses, and normal botanical defense mechanisms.

Important Information

Consult your healthcare professional before use during pregnancy or breastfeeding.

Usnea naturally contains usnic acid. Concentrated oral usnic acid products have been associated with rare but potentially serious liver injury. The reported cases primarily involved substantially different, concentrated usnic-acid-containing products and do not establish the same risk for this finished Usnea tincture; however, caution is appropriate with oral use.

Individuals with known liver disease, abnormal liver function, or those taking medications or supplements that may affect the liver should consult a qualified healthcare professional before use.

Discontinue use and seek medical evaluation if symptoms suggestive of liver injury develop, such as unusual fatigue, persistent nausea, dark urine, yellowing of the skin or eyes, or unexplained upper abdominal discomfort.

Use according to manufacturer directions and avoid prolonged continuous use unless supervised by a healthcare professional.
