Are Insadol and Igatan effective if taken consistently?

My gums feel a bit weak lately, so I'm looking into products like Insadol or Igatan.

Does taking this consistently actually help with gum health?

There are a lot of ads, but I'm curious about honest reviews...

I want to know if it is effective for symptoms like bleeding or numbness, or if it is just a supplement.

I am also curious about how long I need to take it to feel the effects, and I am concerned about whether it is safe to take it long-term.
