Uva Ursi Extract

What Does Uva Ursi Extract Do?

Uva Ursi, also known as Bearberry, is a botanical extract traditionally used for urinary health that has found a niche in performance supplements for its ability to manage fluid balance. It acts primarily as a natural diuretic and mild astringent, helping you achieve a "dryer" look while supporting the body's internal filtration systems.

• Natural Diuretic Effect: The active compound arbutin helps the body flush excess subcutaneous water, which can improve muscle definition and reduce the bloated feeling often associated with high-sodium pre-workouts.
• Urinary Tract Support: It possesses antimicrobial properties that support a healthy urinary environment, which is beneficial for athletes processing high volumes of supplements and protein.
• Anti-Inflammatory Properties: Rich in tannins, Uva Ursi can help soothe internal tissues and reduce minor systemic inflammation during the recovery phase.
• Antioxidant Defense: It contains flavonoids and phenolic acids that help neutralize oxidative stress caused by high-intensity training sessions.

Clinical vs. Gym Bro Dosing

Key Insight: Uva Ursi is most effective when your urine is alkaline. To maximize the conversion of arbutin into its active form, avoid taking it alongside highly acidic supplements like high-dose Vitamin C or acidic fruit juices.

Side Effects & Warnings

• Digestive Discomfort: Due to its high tannin content, some users may experience nausea or stomach cramping if taken without food.
• Urine Discoloration: It is common for your urine to take on a greenish-brown tint; this is a harmless side effect of the arbutin metabolism.
• Electrolyte Depletion: Like any diuretic, it can increase the excretion of minerals. Ensure you are hydrating with electrolytes during use.

Contraindications: Uva Ursi should not be used for more than 5-7 consecutive days. Long-term use is discouraged due to potential toxicity from hydroquinone. Avoid this ingredient if you have pre-existing kidney or liver conditions.
