Your Guide to Licorice root: Benefits, Dosage, and More

Looking to optimize your health or performance with Licorice root? This guide breaks down everything you need to know about this popular Botanical Extract, from its benefits and dosage to the latest research and biohacker insights.

What is Licorice root?

Licorice root is the root of the Glycyrrhiza glabra plant, traditionally used in herbal medicine and as a flavoring agent. It contains various compounds, including glycyrrhizin, which is responsible for many of its effects.

---

Key Potential Benefits & Uses

Based on research and biohacker experiences, Licorice root is often used for:

• Digestive Health: May help soothe the digestive tract lining and support healing of stomach ulcers or reduce heartburn symptoms.
• Respiratory Health: Traditionally used as an expectorant to help clear mucus and ease coughs.
• Adrenal Support: Some forms may influence cortisol metabolism, potentially supporting adrenal function under stress (use with caution).
  • Mechanism: Glycyrrhizin inhibits the enzyme 11-beta-hydroxysteroid dehydrogenase type 2, which inactivates cortisol.
• Skin Conditions: Topical application may help with inflammatory skin conditions like eczema.

---

Scientific Evidence: What Does the Research Say?

• Moderate evidence supports its use for certain digestive issues like ulcers and heartburn, particularly the deglycyrrhizinated form (DGL). Evidence for respiratory benefits and adrenal support is less robust or requires careful consideration due to potential side effects.
• Strength of Evidence: Moderate for specific digestive uses (DGL); Limited/Emerging for other uses, often requiring caution due to side effects.

How to Take Licorice root

• Common Forms: Capsules, Powder, Liquid Extract, Tea, Chewable Tablets (DGL).
• Typical Dosage: Varies significantly based on form, concentration (especially glycyrrhizin content), and intended use. DGL forms are often dosed higher than extracts containing glycyrrhizin. Always follow product instructions or consult a professional.
• Timing: Can be taken between meals for digestive support or as needed for respiratory issues.

---

Synergies & Stacking

• Licorice root is often stacked with other digestive herbs like Marshmallow root or Slippery elm, or respiratory herbs like Thyme.
• Avoid Combining With: Medications for high blood pressure, heart conditions, kidney disease, or diuretics, as it can potentially interact and cause electrolyte imbalances (especially low potassium) or raise blood pressure with forms containing glycyrrhizin.

---

Potential Side Effects & Precautions

Like any supplement, Licorice root may cause side effects, though they are typically dose-dependent and linked to the glycyrrhizin content. These can include:

• High Blood Pressure: Can occur with forms containing significant glycyrrhizin, especially at high doses or prolonged use.
• Low Potassium: Can lead to muscle weakness, fatigue, and irregular heart rhythm.
• Fluid Retention: May cause swelling.
• [Precautions]: Individuals with hypertension, heart disease, kidney disease, liver disease, or hormone-sensitive conditions should avoid forms containing glycyrrhizin. Avoid during pregnancy and breastfeeding. Consult a doctor before use, especially if taking medications. DGL forms are generally safer as most glycyrrhizin is removed.

---

Choosing the Right Form & Quality

• Form Comparison: Deglycyrrhizinated Licorice (DGL) is the preferred form for digestive support and longer-term use as it significantly reduces the risk of side effects associated with glycyrrhizin (like blood pressure elevation and potassium depletion). Standardized extracts containing glycyrrhizin are used for specific purposes (like adrenal support) but require careful dosing and monitoring.
• Quality Tips: Look for products standardized for glycyrrhizin content or clearly labeled as DGL. Choose reputable brands with third-party testing.

Biohacker Insights & Community Experiences

• Common Experiences: Many users report relief from heartburn or indigestion with DGL forms. Some report feeling more resilient under stress with specific extracts, but often with awareness of the potential side effects.
• Pro Tip: If using for digestive issues, chewable DGL tablets may offer better local contact with the esophageal and stomach lining.

Frequently Asked Questions (FAQs)

• Is DGL Licorice root safer than regular Licorice root?
  • Answer: Yes, DGL (Deglycyrrhizinated Licorice) has most of the glycyrrhizin removed, which significantly reduces the risk of side effects like high blood pressure and low potassium.
• Can Licorice root help with stress?
  • Answer: Some forms may influence cortisol levels, potentially supporting the stress response, but this should be approached with caution due to potential side effects on blood pressure and electrolytes.
