Do you trust Chong Kun Dang MSM dietary sulfur supplement?

Since my twenties, I have had joint issues due to dieting and incorrect exercise postures.

Especially when I was young, I jumped rope on asphalt a lot, so my knees are not in good condition.

So, I looked into joint supplements, and most people recommended MSM because they saw a lot of effectiveness.

I trust the Chong Kun Dang brand, so I also trust Chong Kun Dang MSM supplements.

The price is also affordable, so it's good to take regularly.

It's a creaky knee, but I have seen some improvement.
