I trust Chong Kun Dang Jagonwon.

Jongkundang Jagwanwon is a multifunctional joint supplement that contains MSM, N-acetylglucosamine, and calcium to help reduce the risk of osteoporosis and promote joint, cartilage, and bone health. According to human application test results of MSM, in adults aged 40 to 76 experiencing knee discomfort, 12 weeks of MSM intake was shown to reduce joint pain and improve joint physical condition.
MSM contains a maximum daily intake of 2,000 mg, and N-acetylglucosamine extracted from domestic red crab shells is a functional ingredient that needs to be ingested from outside sources. It is said to be a substance that constitutes glycosaminoglycans, which are components of cartilage, such as hyaluronic acid and chondroitin.

This is a product I would recommend for those who are concerned about joint health, experiencing decreased cartilage function due to aging, or need management.

I think it's convenient because I can easily take one packet once a day and take care of my joint health.

Jongkundang Joint En Jagonwon MSM Joint Supplement contains 4th-grade premium MSM with 98% purity, combined with up to 20 carefully selected sub-ingredients to provide additional nutrition.

As with Chong Kun Dang, it contains no additives or excipients, so you can consume it with confidence.
