Jung Kwan Jang and Cheong Kwan Jang are names used for the Korean brand 정관장 from Korea Ginseng Corporation (KGC). You will also see the styling JungKwanJang. The different English names do not, by themselves, identify different products.
The name is only the starting point
Two packs from the same brand can have different ingredients, concentrations, quantities or directions. A similar name does not prove that their formulas are equivalent, and spelling alone cannot authenticate a product.
Finding the range here
Our catalogue has a Jung Kwan Jang collection and a KGC Cheong Kwan Jang collection, reflecting the names in the supplier catalogue. Compare the exact product name and pack information in both.
Compare quantities carefully
Keep these measurements separate: the net contents of the pack, the portion or daily amount stated for the product, and the quantity or concentration of a particular ingredient. A percentage of extract is not automatically a milligram amount of an active compound per serving.
Use only the figures documented for the specific reference. Do not transfer a composition or daily amount from another market or pack with a similar name.
Before choosing
Read the full ingredients, allergens, directions and warnings shown for the reference. If a detail needed for your decision is missing, contact us before ordering. The brand's history is context; it does not replace that information.
Seoul Rituals describes the product and its stated composition without promising to prevent, treat or cure disease. Food supplements should not replace a varied and balanced diet or a healthy lifestyle.
