LEC Inc. (Headquarters: Chuo-ku, Tokyo; Representative Director: Mitsuo Aoki) launched Guronsan Yojinbo®, a new product from its nutritional drink brand Guronsan, in February 2026.

Guronsan Yojinbo®

【Background of Development】
Targeting males aged 40-60 who frequently attend social gatherings, experience declining physical strength, and are prone to liver strain, we developed drink and tablet type products that can be used "before and after drinking." These products contain ingredients that support liver function and aim to alleviate the fatigue associated with hangovers due to nutritional deficiencies.

Usage Scene

【Product Features】
・Efficacy: "Improvement of fatigue due to hangovers caused by nutritional deficiencies"
The strength of Guronsan Yojinbo is that it is a "quasi-drug" that can claim the efficacy of improving hangover fatigue.
・Refreshing and crisp orange flavor (Drink type)
Guronsan Yojinbo (drink type) contains glucuronolactone, which aids liver function, thiamine nitrate (Vitamin B1), which tends to be deficient due to alcohol consumption, and nicotinamide (Niacin), which acts as a coenzyme for alcohol-degrading enzymes, along with royal jelly containing various nutrients, as active ingredients.
・Non-caffeinated and easy to drink before bed (Tablet type)
In addition to glucuronolactone and thiamine nitrate (Vitamin B1), it contains taurine, which aids liver function, and L-cysteine, which promotes acetaldehyde metabolism.
