Prior to supplementing Licorice, please be aware of Glycyrrhizin (the agent that increases cortisol and reduces testosterone) and, if these results are not desired, try to get products with low Glycyrrhizin content (less than 500 mg total dose daily). 150 mg has been confirmed to not influence these hormones
Traditional Chinese Medicine recommends a decoction of 8-15 g Licorice for health protection and up to 100 g for disease states. Consumption of licorice in these doses as a food product does confer the same properties as supplementation, but the caloric and carbohydrate intake from either the root of confectionaries derived from the root need to be accounted for.
With supplementation, intakes of Licorice in the range of 150-300 mg daily appear to be most commonly used and intakes of Deglyccyrhizinated (without Glycyrrhizin) up to 1800 mg daily for 4 weeks are not associated with toxicity in humans. *
Liquid extract
Licorice extract is the most commonly found form of licorice. It’s used as a commercial sweetener in candies and beverages. Licorice extract consumption by an individual should not exceed 30 mg/mL of glycyrrhizic acid. Ingesting more could cause unwanted side effectsTrusted Source.
Powder
Health food stores and online specialty retailers sell licorice powder. Combined with a gel base, it can become a topical ointment that clears the skin. In its powder form, licorice is especially helpful in treating eczema and acne. You can also pour the powder into vegetable capsules and ingest them orally. The recommended dosage of licorice root is less than 75 milligrams per day, according to World Health Organization (WHO) guidelines.
Tea
Licorice plant leaves, dried and crushed into a tea, have become popular. You can purchase these teas at supermarkets or health food stores and online. Teas are used to promote digestive, respiratory, and adrenal gland health. When you see herbal teas for “bronchial wellness” and “cleanse and detox,” they usually contain forms of licorice. The popular throat remedy known as Throat Coat tea is a combination of marshmallow root, licorice root, and elm bark. It’s not recommended that people ingest more than 8 ounces of licorice tea per day.
DGL
DGL is licorice with glycyrrhizin removed, which is a safer form. DGL should contain no more than 2 percent glycyrrhizin. This form is recommended for gastrointestinal symptoms as long-term intake may be needed.
DGL is available in chewable tablets, capsules, tea, and powder. Consume no more than 5 grams of DGL per day. *
