Do Niacin supplements help to increase circulation and heal areas with poor blood flow?

Question

I am considering trying Niacin supplements to help heal an injury in the inside of the knee, where blood flow is supposed to be poor. I heard that Niacin dilates blood vessels and can increase blood flow. Is that true? Can it help bring more blood flow to the knee? Thanks

Answer 1

Niacin (B3) is needed for proper circulation.

Answer 4

The flushing reaction is a superficial capillary dialation. This will not affect deep circulation to body areas so the answer is no. Niacin will not improve circulation to body areas like the knee.
