Joint supplements are from Chong Kun Dang.

Jongkundang MSM is a health supplement recognized by the Korea Food and Drug Administration, containing functional ingredients such as MSM, as well as vitamins D and zinc.

MSM is a dietary sulfur component that helps with joint and cartilage health, and is important for forming collagen, which makes up cartilage and ligament tissues.

Vitamin D is a nutrient that plays a crucial role in the formation and maintenance of bones, and must be consumed to prevent osteoporosis.

Zinc is an essential element for immune function and a nutrient necessary for normal cell division.

I think the Jongkundang joint supplement, made up of things that help with joint health like this, is good.
